Description

The present invention relates to a power supply system having an energy storage device and a receiving device for the energy storage device according to the preamble of patent claim 1 and a passenger vehicle comprising a power supply system according to the invention.

Energy supply in private road transport is almost 100% geared to crude oil or gas for the operation of internal combustion engines. While advances in power consumption have been made in recent decades, they are far behind expectations and necessity. This is especially true with regard to 150 years of development work on the internal combustion engine and future supply security with crude oil.

The efficiency, ie the measure of the ratio of supplied power to the delivered useful power, has increased comparatively slightly and has become established at around 25%. This means. that about 75% of the energy supplied is not used for the actual locomotion.

Even with hybrid drives, the disadvantages of the main engine combustion engine drive source remain. In addition, other negative aspects, such as significantly increased feedstock and energy costs in development, production and utilization, are added. In contrast, there is a comparatively low energy savings, which can be completely eliminated depending on the driving style and driving distance.

A conversion from mineral oil to biodiesel (fatty acid methyl ester) will not be able to assert itself to any appreciable extent because the amount that can be generated is far below the demand. In addition, there is an extremely negative eco-balance over the entire production process of biodiesel. Due to the lucrative cultivation of the necessary oil plants worldwide, the limited agricultural area even marks a decline in much more necessary food production.

Other alternative sources of power do not play any significant economic role.

• – Enorme Energieverschwendung, bedingt durch den geringen Wirkungsgrad;
• – Abhängigkeit von rarer werdenden Erdolvorkommen aus oftmals Krisengebieten, bei gleichzeitiger Erhöhung des Bedarfs an Individualverkehr;
• – Abhängigkeit vom Erdöl als unersetzbarer wichtiger Rohstoff in weiten wirtschaftlichen Bereichen wie Chemie und Medizin;
• – Abhängigkeit der Weltwirtschaft und der globalen Stabilität vom Erdöl; Kostspielige und gefährliche Gewinnung, ineffektiver Transport des Energiemediums Erdöl; und
• – Hohe Umweltverschmutzung, die sich negativ beim Klimawandel auswirkt.

The conservative drive system has the following disadvantages in particular:

• - Enormous energy waste, due to the low efficiency;
• - dependence on rarer petroleum deposits from crisis areas, while increasing the demand for private transport;
• - dependence on crude oil as an irreplaceable important raw material in broad economic sectors such as chemistry and medicine;
• - dependence of the world economy and global stability on oil; Expensive and dangerous extraction, inefficient transport of the energy medium oil; and
• - High pollution, which has a negative effect on climate change.

The necessity of a radical change in the energy supply of the current individual traffic with internal combustion engine is not to be overlooked. New developments with potential for rapid change in the situation are currently not foreseeable. It is possible that current developments consider a test and trial period of approx. 10-15 years to be realistic, after which an enforcement period of another approx. 10-15 years can be expected. Even these optimistic outlooks are not sufficient to counter the expected effects in the environment, society and the economy. An effective method of upheaval must have prevailed almost globally over the next 5-10 years. This has to succeed with resources that are available today.

In the small power range (up to approx. 1 kW), electric motors have typical efficiencies of approx. 60-90 percent, while in the range of higher outputs (> 1 kW) efficiencies of 98 percent are quite common. Except for a small amount, the much larger part of the energy is converted into the already desired rotational movement. Partly even the heat release can be used.

Electric motors can also be operated in the same unit as generators and convert excess kinetic energy back into elktrische Bordenergie.

For example, the US 2004/0040755 A1 a completely electric motor vehicle. This vehicle comprises two electric motors, which are connected via clutch plates with drive wheels of the vehicle. Each of these electric motors are assigned insertion channels, in the energy storage devices of a generic power supply system, in the form of replaceable batteries, are inserted.

In addition, the reveals DE 44 11 843 A1 another energy storage device, in the form of a device for replacing batteries. It is proposed that a package of batteries be enclosed in a housing for ease of handling and safety of the occupants of an electric vehicle. The Housing with batteries is hung below and outside a vehicle floor and air cooled. Used batteries are replaced with charged batteries and the vehicle can continue driving.

Since the end of the 20th and the beginning of the 21st century, accumulators have been developing for the first time in compact designs up to today's variety in use, function and durability. In the necessary short-term, they currently represent the most enormous development potential in terms of future ease of use, security and rapid dissemination.

Electricity can be won from many, even regenerative forms of energy in different and independent locations all over the world.

Electromobiles already existed in the early stages of global motorization. Among other things by the then progress in the field of internal combustion engines, the apparent security of supply with the energy carrier oil, as well as the insufficient development in the field of electrical energy storage in terms of durability, size and energy density, the internal combustion engine prevailed.

A particularly serious disadvantage is the time constant present in the case of a charge, the charging curve of the accumulator resulting therefrom, and the associated expenditure of time until the full capacity is restored, which prevents its use as an energy store that can be quickly filled up. The necessary charging times (depending on the battery and state of charge) have been considerably shortened to date, but it still exists to the extent that the charging procedure means more than a short stay, especially compared to the energy consumption in a car with an internal combustion engine.

Even waiting times in the double-digit minute range would be a fact. which prevent broad suitability for everyday use and a noteworthy dissemination.

For the exchange of batteries suggests, for example DE 10 2005 056 972 A1 an energy storage module with an energy storage unit, which is formed from a plurality of battery cells, an electronic unit and a carrier, on which the energy storage unit and the electronic unit are arranged before.

A similar module is also from the US 2001/0031392 A1 and the US 5,866,276 known.

To overcome these disadvantages, therefore, the already mentioned systems have been developed in the prior art which make it possible to exchange the complete accumulators of the vehicle for charged accumulators within a short time compared to a complete charging of the accumulators.

However, the energy storage systems known from the prior art have the disadvantage that a user can exchange only the complete battery pack. In addition, depending on the available volume, the automobiles have different types of accumulators, which differ in particular from one another by volume and capacity. As a result, the systems are only suitable for avoiding long service lives of the vehicle during the charging process. For this purpose, a user of a vehicle holds several accumulators at his home location and, if necessary, exchanges the accumulators that are deflated by charged accumulators. Therefore, due to the limited range of the vehicles, a user of the vehicle can only benefit from the advantage of interchangeability of the accumulators if he is within a predetermined radius of his home location. If he moves too far away from this hometown, he must first interrupt the drive with the vehicle to recharge the battery located in the vehicle.

In particular, due to the number of different accumulators that would have to be provided by a charging station, it is economically unattractive to build a system of charging stations similar to the existing refueling station system for petroleum-based fuels.

It is therefore an object of the present invention further develop the generic power supply system such that the disadvantages of the prior art are overcome, in particular to achieve an increase in the range of electric vehicles while minimizing the time required for recharging the electric vehicle with energy and inexperienced users a time and labor efficient and safe, in particular damage or destruction of the energy storage device, the receiving device and / or the motor vehicle avoiding, to allow recharging the vehicle, the user should also have the opportunity to supply only his desired amount of energy to the vehicle, similar to a gasoline-based vehicle possible selection of how much fuel is poured into a tank.

This object is achieved by the characterizing features of claim 1.

The claims 2 to 23 describe preferred embodiments of the invention.

Furthermore, the invention relates to the use of a power supply system according to the invention in a passenger vehicle according to claim 24.

It is particularly preferred that the passenger vehicle has the features of claim 25.

The invention is therefore based on the surprising finding that an energy storage device can be designed such that a time-efficient, safe and easy refueling of an electric vehicle is made possible by the energy storage device having a standardized or standardized size and at the same time arranging connection elements on the energy storage device are that when inserting the energy storage device into a receiving device of a vehicle no special orientation of the energy storage device relative to the recording or no special plug-in device of the energy storage device must be considered in the recording. In particular, a reverse polarity, which could lead to short circuits, excluded. The provision of a standardized size of the energy storage device makes it possible for different vehicles to be "refueled" with one and the same energy storage device. Thus, the different vehicles may have a different number of receiving devices for the energy storage devices.

Compared to permanently installed energy stores of electrically powered automobiles on board the vehicles, which are charged via a power cable to a power outlet, in which process the vehicle is tied to this location and can not be used for transportation, various advantages are achieved.

The car has a possibility to replace the energy storage for the movement energy in a short time, so that it is suitable for continuous use, so for everyday life and short-term implementation.

It can be spent at a suitable gas station from the energy store, the time of loading. The actual automobile changes only the energy cell and is therefore immediately operational.

Such an automobile can also be charged conventionally via the socket in addition to the exchangeability of the accumulator.

The power required for the charge can be inexpensively transported via lines, the energy storage are fed back to the circuit after the charging time, errors are diagnosed at the gas station and fixed.

Depending on the size of the electric drive used in the automobile and / or the available volume, a different number of energy storage device can be used. This makes it possible to achieve equality of energy storage, with benefits for charging at the gas station and supply of spare parts.

The infrastructure of filling stations for internal combustion engines can be used for the provision of standardized energy storage and be adapted to the range of automobiles.

The supply networks of these stations can be different sizes, and z. B. as a stand-alone solution with gas station and energy production in one place from z. B. regenerative energies can be provided.

Energy companies can be integrated into the infrastructure of the battery network as energy storage for the urgent need of balancing the existing load peaks in energy production and production.

Finally, the use of the normalized energy stores allows them to be combined to a user-desired amount of energy by adapting the number of charged energy stores purchased by a user so that a user can tailor the amount of energy to his needs, especially to purchase the desired amount of energy Vehicle can supply. This modular design of the energy storage also means that not only the desired amount of energy, but also the weight required for this amount of energy must be arranged in the form of energy storage devices in the vehicle and so the total weight of the vehicle can be reduced, resulting in a further energy savings leads.

Further features and advantages of the invention will become apparent from the following description in the preferred embodiments of the invention are explained with reference to the accompanying drawings.

In 1 is a perspective view of an energy storage device 1 shown. The energy storage device 1 serves in particular for the storage of electrical energy, thus represents an accumulator, which is used in particular for supplying a drive device of a passenger car with energy. However, the present invention is not limited to electrical energy storage devices. Thus, gases can also be stored, with an energy potential difference resulting from different pressures at the connection elements.

The energy storage device 1 includes a housing 3 which comprises an electrically insulating material. As will be explained below, the energy storage device 1 inserted in a use in a passenger vehicle in a receiving device. In this case, the energy storage device 1 a symmetry plane SE1, wherein the outer contour of the energy storage device 1 is formed mirror-symmetrically to the plane of symmetry SE1. The energy storage device 1 moreover comprises a first connection device, which in 1 illustrated first connection elements 5 includes.

In 2 is a side view of the energy storage device 1 from direction A in 1 shown. As 2 can be seen, has the energy storage device 1 in addition to the first plane of symmetry SE1 a second plane of symmetry SE2, with respect to the energy storage device 1 also has a mirror-symmetrical contour shape, on. In addition, results from 1 a third plane of symmetry SE3 of the contour shape of the energy storage device 1 , wherein the plane of symmetry SE3 of the leaf plane of the 2 equivalent.

As 2 can be seen, comprises the first connection device of the energy storage device 1 next to the first connection elements 5 a second connecting element 7 ,

The first connection device of the energy storage device 1 is constructed such that through the first connection elements 5 positive poles of the energy storage device 1 be provided while through the second connection element 7 a ground pole is provided.

In the 3 and 4 are views of the energy storage device 1 of the 1 from direction B ( 3 ) or C ( 4 ). In the 3 and 4 the leaf plane represents the plane of symmetry SE1. Like 2 can be seen, are the connection elements 5 . 7 with respect to the plane of symmetry SE1 arranged on opposite surfaces of the energy storage device. In 3 are therefore the first connection elements 5 drawn in solid, while the second connection element 7 placed on an opposite surface with respect to the first connection elements 5 is arranged, dashed dargstellt is. Analogously, in 4 the second connection element 7 shown in solid, while the connection elements 5 spiked are drawn. However, the present invention is not limited to that the terminal members of the first terminal device are disposed on opposite surfaces of the energy storage device. Thus, the respective connection elements can also be arranged on a common surface of the energy storage device.

As is clear from the 3 and 4 gives, are the first connection elements 5 mirror symmetrical in each case to the planes of symmetry SE2 and SE3 or point-symmetrical to an intersection of the planes of symmetry SE2, SE3 and the plane of the paper on the respective surface of the energy storage device 1 arranged. On the other hand, the second connection element 7 arranged at the intersection of the symmetry planes SE2, SE3 and the paper plane. This arrangement allows the energy storage device 1 can be inserted into a receiving device substantially in any direction and any orientation. So can the energy storage device 1 be inserted into a receiving device having an opening which in 2 illustrated cross-sectional shape of the energy storage device 1 equivalent. By a suitable arrangement of mating contacts to the connection elements 5 . 7 The energy storage device can also with regard to the 2 can be inserted rotated 180 °. Furthermore, by the symmetrical arrangement of the connection elements 5 . 7 on the energy storage device 1 the energy storage device 1 in the 3 respectively. 4 rotated by 90 °, 180 ° and 270 ° are inserted into a receiving device and at the same time it is ensured that corresponding mating contacts to the connection elements 5 . 7 the receiving device, the connection elements 5 . 7 Contact without it can lead to incorrect polarity.

As can be seen in particular from the 3 and 4 results are the connection elements 5 . 7 formed as contacts, wherein the surface of the contacts of the connection elements 5 smaller than the surface of the connection element 7 is. In addition, the connection elements 5 . 7 , in particular in 2 is shown in wells of the energy storage device 1 arranged. It is also achieved by this arrangement of the connection elements that it can not lead to a short circuit of the connection elements when the energy storage device is deposited on an electrically conductive surface. With regard to a consideration of the symmetry of the energy storage device 1 with respect to the symmetry planes SE1, SE2 and SE3, however, these depressions are disregarded. It is therefore under the contour shape of the energy storage device 1 the square symmetrical cross-sectional shape of the energy storage device 1 with respect to the planes of symmetry SE1 and SE2 in FIG 2 or the square-symmetrical contour shape of the energy storage device 1 with respect to the symmetry planes SE2 and SE3, as shown in FIG 3 and 4 is shown, understood.

As will be explained later, leads the different size of the connection elements 5 . 7 to the advantage that an unwanted contacting of the connection elements 5 by a mating contact, for contacting the connection element 7 serves, can be prevented by a corresponding dimensioning of the mating contact, in particular can be prevented in this way that the mating contact in the smaller-sized recess of the connection elements 5 can reach into it, but only in the recess of the connection element 7 fits.

In alternative embodiments, it may be provided that the plurality of connection elements 5 can be configured by a single contact, which is designed as an annular contact. This would achieve that the energy storage device 1 in the 3 and 4 could be rotated in the leaf level at any angle, without any contact of the connecting elements 5 . 7 would be influenced.

In the 5 and 6 are perspective views of the energy storage device 1 on the in the 3 and 4 shown sides of the energy storage device 1 shown.

In 7 is a side view of a second embodiment of an energy storage device according to the invention 1' shown. The elements of the energy storage device 1' that of the energy storage device 1 correspond, bear the same reference numerals, but simply deleted.

The energy storage device 1' differs from the energy storage device 1 in that next to a first Connecting device, the first connection elements 5 ' and the second connection element 7 ' comprises, a second connection device comprises, the third connection elements 9 ' and a fourth connection element that through the second connection element 7 ' is formed. The second or fourth connection element 7 ' represents a neutral or ground potential of the energy storage device 1' ready. On the other hand, there are the first connection elements 5 ' and the third connection elements 9 ' on different positive potentials:
This structure of the energy storage device 1' causes the energy storage device 1' in different vehicles that require different operating voltages can be used or different voltages are provided by one and the same energy storage device.

In the 8th and 9 are views of the energy storage device 1' from direction D ( 8th ) and from direction E ( 9 ) in 7 shown. As can be seen from these figures, the in 8th solid connection elements 5 ' . 9 ' on a first surface of the energy storage device 1' arranged while the connecting element 7 ' , this in 7 is shown in dashed lines, on an opposite surface of the energy storage device 1' is arranged. Similar to the energy storage device 1 is the second or fourth connection element 7 ' at the intersection in the plane of symmetry SE2 ', SE3' and the paper plane, while the first connection elements 5 ' point symmetrical to this point of intersection or mirror symmetry to the symmetry planes SE2 'and SE3' are arranged. Also, the third connection elements 9 ' mirror-symmetrical to the planes of symmetry SE2 'and SE3' arranged or mirror-symmetrical to the intersecting lines of the symmetry planes SE2 'and SE3'. However, the connection elements have 5 ' a smaller distance to the intersection of the plane of symmetry SE2 ', SE3' and the paper plane, as the connecting elements 9 ' ,

In the 10 and 11 are perspective views of the energy storage device 1' on the in the 8th respectively. 9 shown surfaces shown.

In 12 is a perspective view of a front side of a receiving device according to the invention 11 shown. The recording device 11 points in total 10 Receiving devices in the form of slots 13 on. Into the bays 13 can total 10 Energy storage devices 1' be inserted. The energy storage devices 1' are not only in terms of their external shape, but also in terms of their energy capacity substantially uniform so standardized or standardized configured. Thus, the structure of the receiving device makes it possible for a user of a vehicle to make an arbitrarily graded "refueling" of the vehicle with energy depending on the energy requirement.

Although in 12 all bays 13 with energy storage device 1' are occupied, it is also possible that only single bays 13 with energy storage device 1' be occupied. For example, if a user merely plans a short-haul trip, he may only have a smaller number of bays with energy storage devices 1' occupy. As a result, it can reduce the total weight of the vehicle and thus also reduce the energy consumption of the vehicle.

Also, this can significantly reduce the "refueling time" since only the desired number of fully charged energy storage devices 1' in the bays 13 is introduced. Also, this modular structure of the vehicle's power system allows a user to have only a limited number of energy storage devices, for example, in the case where he has only a limited amount of money available 1' Being discharged by charged energy storage devices 1' can replace. The energy storage devices 1' are provided for this purpose at charging stations similar to the currently known gas stations and recognizes a user that discharged energy storage devices 1' through recharged energy storage devices 1' must be replaced, so he drives to such a charging station and removes the emptied energy storage devices 1' from the receiving device 11 and, after a corresponding payment, takes a desired number of charged energy storage devices 1' which he then places in the drawers 13 inserts. This causes a "refueling" of the vehicle is made possible in a very short period of time and beyond a refueling with the greatest possible flexibility, in particular with regard to the amount of energy supplied to the vehicle, can be performed.

In 13 is a perspective view of the receiving device 11 from direction F in 12 shown.

Like both 12 as well as 13 can be seen, are in each slot energy transfer devices 15 assigned. How the particular 13 it can be seen, are the energy transmission devices 15 the two lower rows of slots 13 configured separately from each other while the energy storage devices 15 the three upper rows of slots are in communication with each other such that the respective three upper energy storage devices 1' at a slot in the bays 13 be connected in parallel with each other electrically.

In 14 is a side view of an energy storage device 1' that are in a slot 13 the receiving device 11 is shown. Again 14 can be seen, includes the energy transmission device 15 first energy transfer elements in the form of contacts 17 , second energy transfer elements in the form of contacts 19 as well as third energy transfer elements in the form of contacts 21 , The contacts serve 17 for contacting the first connection elements 5 ' the energy storage device 1' , The contacts 19 for contacting the second connection element 7 ' the energy storage device 1' and the contacts 21 for contacting the third connection elements 9 ' ,

As will be explained later, the contacts are 17 . 19 . 21 equipped as bifurcated contacts. In this case, the contacts are designed to be elastic and designed such that they engage in insertion of the energy storage device 1' in the slot 13 be elastically deflected and moved by a restoring force in the direction of the respective connection elements. Here, the elastic restoring force through the contacts 17 . 19 . 21 itself or by an additional return element, such as a spring element, are provided. It can also be provided that the energy storage device 1' by a fixing device, not shown within the slots 13 is fixed. It can be provided in particular that the fixing device so with the contacts 17 . 19 . 21 or the reset element interacts. that the contacts 17 . 19 . 21 only on the connection elements 5 ' . 7 ' . 9 ' rest when the energy storage device 1' fixed by the fixing in the slot 13 located.

In 15 is a plan view of the energy storage device 1' of the 14 from direction G, while in 16 a plan view of the energy storage device 1' in 14 from the direction H is shown. As can be seen in particular from a comparison of 15 and 16 with the 8th and 9 results, contacted the contact 17 one of the first connection elements 5 ' , the contact 19 the second connection element 7 ' which is in 16 through the contact 19 is hidden and the contact 21 one of the third connection elements 9 ' , It lies in the 15 displayed part of the contact 19 on a surface of the housing 3 ' on while in 16 represented part of the contacts 17 and 21 on a surface of the electrically insulating housing 3 ' rests. By contacting the connection elements 5 ' . 7 ' . 9 ' can be between the contacts 17 and 19 a first potential and between the contacts 19 and 21 a second potential can be tapped. So it is conceivable that to supply a consumer within the vehicle, the potential between the contacts 17 . 19 is used, for example, 12 volts, while for another consumer, the potential difference between the contacts 21 and 19 , for example, 24 volts is used. It is also conceivable that different vehicles or different bays of a receiving device in a vehicle exclusively the contacts 17 or the contacts 21 exhibit. For example, in a vehicle that has only consumers who have a potential difference between the contacts 19 and 21 need on the contacts 17 be waived. At the same time, these energy storage devices 1' However, be used in the various bays or different vehicles for a power supply, regardless of which potential difference is tapped in the respective vehicle or the respective slot.

In addition, from the 15 and 16 recognizable that the contacts 17 and 21 compared to the contacts 19 have different widths. This will ensure that the contacts 19 exclusively with the connection elements 7 ' can come into contact because, as described above, the connection elements 7 ' a larger dimension than the connecting elements 5 ' respectively. 9 ' and to a surface of the energy storage device 1' are arranged deepened. In these wells, only the contacts 17 . 21 intervene while the contacts 19 through the housing 3 ' from their contacts 7 ' stay at a distance. This will cause the formation of a short circuit upon insertion of the energy storage device 1' in the receiving device 11 ' avoided. Also, thereby the connection elements 5 ' respectively. 9 ' , as described above, are replaced by annular contacts, thus ensuring that the contacts 19 not with these connection elements during insertion of the energy storage device 1' into the respective slot can come into contact. Also, the contacts can 17 and 21 have different dimensions in order to avoid that the respective contacts unintentionally with connection elements to which a contact is not desirable, can come into connection.

In the 17 and 18 are perspective views of the sides of the energy storage device 1' that in the 15 and 16 are shown shown.

Finally, in 19 a detailed perspective view of the contacts 17 . 19 . 21 shown. As 19 it can be seen, the contacts have 17 . 19 . 21 elastic contact tongues 23 . 25 . 27 on, which make it possible for contact elements 29 . 31 . 33 from one to the 14 to 18 shown position in which the respective connection elements of the energy storage device 1' be contacted, deflected by a through the reeds 23 . 25 . 27 constructed restoring force against the respective connection elements or the surfaces 3 ' the energy storage device 1' to be pressed.

By the arrangement of the connection elements on the energy storage device 1' and the design of the contacts 17 . 19 . 21 and the leadership of the energy storage device 1' in the slot is further ensured that when inserting the energy storage device 1' in the slot 13 the contact 17 excluding the connection elements 5 ' , the contact 19 excluding the connection element 7 ' and the contact 21 excluding the connection elements 9 ' contacted.
