Description

The invention relates to a method for providing a proposal for an electric charging station for charging an electrically operated truck, the electrically powered truck transmitting a charging request to a charging management system via a communication unit. The invention also relates to an electronic charging management system with an interface for receiving a charging request and for outputting a proposal for an electric charging station, the electronic charging management system being designed to carry out the aforementioned method.

Trucks often need parking along their route. For example, this is made possible along motorways at motorway service stations. The use of battery-powered trucks results in an increased number of parking spaces. As a result, charging options along the respective travel routes of the electrically operated trucks are managed. Furthermore, parked trucks are not allowed to be moved during a legally prescribed driving break. For partially or fully electrified commercial vehicles, this means that they are not allowed to be moved even after they have been fully charged, which would block a charging station for other vehicles.

the DE 10 2018 203 387 A1 discloses a vehicle charging station having an electric charging system with a voltage converter. This provides a central distribution system for charging several vehicles.

The object of the present invention is to enable an electrically powered truck to be charged more efficiently.

This object is achieved by a method and an electronic charge management system according to the independent patent claims. Meaningful further developments result from the subclaims.

One aspect of the invention relates to a method for providing a proposal for an electric charging station for charging an electrically operated truck, the electrically powered truck transmitting a charging request to a charging management system via a communication unit. In addition to the charging request, information about the current state of charge of the electrically operated truck and / or a current travel route is transmitted to the charging management system, with a current driving duration and / or an upcoming steering break in the electrically operated truck being recorded and transmitted to the charging management system. Depending on the current state of charge and / or the current travel route and / or the current driving time and / or the upcoming driving break, the charging management system provides the electrically operated truck with the proposal for the electric charging station for selection.

The proposed method can automatically provide an improved charging option for the electrically operated truck. In particular, the different current conditions of the electrically operated truck can be taken into account when the electric charging station is provided. As a result, for example, the electrically operated truck can use its upcoming steering break more efficiently, since an electric charging process can be carried out during the upcoming steering break. For example, it can also be achieved that there are shorter waiting times for a charging facility for electrically operated trucks. In particular, the proposed electric charging station for selection can give the electrically operated truck an overview of an available charging option.

Another aspect of the invention relates to an electronic charging management system with an interface for receiving a charging request and for outputting a proposal for an electric charging station, the electronic charging management system being designed to carry out a method according to the aspect just described or a development thereof.

Further advantages, features and details of the invention emerge from the following description of preferred exemplary embodiments and on the basis of the drawing (s). The features and combinations of features mentioned above in the description as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the single figure can be used not only in the specified combination, but also in other combinations or on their own, without the frame to leave the invention.

The single figure shows a charging management system for providing an electric charging station for charging an electrically operated truck.

For example, the figure shows an electrically powered truck 1 . In the case of the electrically powered truck 1 in particular, it is a battery-powered truck or an electrified commercial vehicle. It is also conceivable that other types of motor vehicles can be designed. It is also conceivable that it is an electrically operated vehicle or a hybrid vehicle.

The electrically powered truck 1 has an electrical energy store 2 on. This requires the electrically powered truck 1 a charging option at an electric charging station 3 to the electrical energy storage 2 to be able to load.

Should now be the electrically powered truck 1 a charging option for its electrical energy storage device 2 need, so can the electrically powered truck 1 automatically via a communication unit 4th of the electrically operated truck 1 a charge request to a charge management system 5 to transfer. The charging request is transmitted via a communication link 6th , for example via a mobile radio standard, to the charge management system 5 . It is also conceivable that the user of the electrically operated truck 1 via an input unit of the communication unit 4th the charge request manually to the charge management system 5 transmitted. With the charge management system 5 it is in particular a central server or a data cloud with which the charging requests from electrically operated trucks in combination with a large number of electric charging stations 3 can be managed.

In particular, additional information about a current state of charge of the electrical energy store can be provided with the aid of the charge request 2 of the electrically operated truck 1 and / or a current travel route 7th the charge management system 5 via the communication technology and, in particular, wireless connection 6th transmitted and made available. With the current itinerary 7th it is, in particular, the course of the route or the course of the current travel of the electrically operated truck that is being carried out 1 to a destination 8th .

For example, the charge management system includes 5 an interface 9 , with which the charging request of the electrically powered truck 1 can be received.

Furthermore, a current driving duration and / or an upcoming steering break of the electrically operated truck can be used 1 recorded and via the communication link 6th the charge management system 5 be transmitted. The current driving time is, in particular, the current driving time or driving time or driving time of the electrically operated truck 1 . The upcoming steering break is, in particular, a legally prescribed steering break, which is taken from the electrically operated truck 1 and in particular by the user of the electrically powered truck 1 must be adhered to.

In particular, the charge management system 5 depending on the current state of charge and / or the current travel route 7th and / or the current time and / or the upcoming break a suggestion for the electric charging station 3 the electrically powered truck 1 to be provided for selection. Thus, in particular, the electrically powered truck 1 several possible potential charging options at the electric charging station 3 to be provided for selection. In particular, the current state of charge of the electrical energy store can be used 2 and / or the route of the current travel route 7th and / or the driving time and / or when the upcoming driving break must be carried out when determining the electric charging station 3 must be taken into account. Thus, the electrically powered truck 1 a charging option adapted to the current situation at the electric charging station 3 to be provided for selection. This allows, for example, the electrically powered truck 1 automatically the suggested selection of the electric charging station 3 accept or the proposal can be given to the user of the electrically powered truck 1 are offered for selection, so that this is the suggestion of the electric charging station 3 can confirm or reject.

In particular, with the proposal for the electric charging station 3 a charging point and / or a charging time and / or a type of electrical charging station 3 be determined. This means that you can take into account the different circumstances and situations when preparing the proposal for the electric charging station 3 must be taken into account. In particular, the charging time can be adapted to the upcoming driving break and the charging point of the electric charging station 3 can be attached to the itinerary 7th be adjusted.

For example, the electrical charging station corresponding to the proposal 3 from the charge management system 5 automatically for a reservation time for the electrically powered truck 1 be reserved. Thus, the electrically powered truck 1 a certainty about the availability of the charging facility can be granted. In particular, the electrically powered truck can thereby 1 and especially the user of the electrically powered Trucks 1 When looking for a charging option, depending on the various factors, can be relieved by automatically finding a suitable charging option at the electric charging station 3 reserved and therefore the electrically powered truck 1 provided.

For example, the charge management system 5 at a point in time which is before the time of the reservation, check whether the reserved electric charging station 3 is available at the time of reservation and, if not, find an alternative electric charging station and the electrically powered truck 1 offered for selection or automatically reserved. It can thus be ensured that the reserved and required electrical charging station is actually used at the time of the reservation 3 for the required electrical charging process for the electrically operated truck 1 can be provided. Thus, the electrically powered truck can be prevented 1 in front of a not free and in particular occupied electric charging station 3 stands, as a result of which, for example, the driving time and / or the upcoming driving break cannot be observed. Problems can also arise because of the blocked electrical charging station 3 the current state of charge is not sufficient to drive to the nearest electric charging station.

In particular, with the help of the charge management system 5 the electric charging station according to the proposal 3 indicate at least one such charging power that a charging process of the electrically operated truck 1 within the prescribed driving break of the electrically operated truck 1 can be carried out. It can thus be achieved that the upcoming legally prescribed steering break can be used efficiently and, if necessary, the electrical energy storage device 2 can be fully charged during this steering break.

Furthermore, the electrically operated truck can be charged 1 at the proposed electric charging station 3 continuously monitored by a monitoring system, with the electrical charging station at the end of the charging process 3 a warning about leaving the electric charging station 3 on the electrically operated trucks 1 transmitted. This can result in unnecessary blocking or rectification of the electric charging station 3 prevented so that a following vehicle can use the electric charging station 3 can take advantage of.

In particular, with the electronic charge management system 5 the user of the electrically powered truck 1 and / or the electrically powered truck 1 a not yet occupied, i.e. currently free, charging option at an electrical charging station 3 recommended. Are for example along the route 7th The charging management system recommends that all charging options are occupied 5 the electrically powered truck 1 the best possible charging option through intelligent calculation and selection of the still achievable charging option within the permitted driving time or driving time. For example, it can be that the charging facility or the electrical charging station 3 is blocked. The route is calculated in such a way that the driving break is always at an available electric charging station 3 can be carried out, which results in that even by detouring the travel route 7th a faster total travel time to the destination 8th can be achieved. The intelligent selection or determination of the electric charging station 3 also takes into account that for long breaks (e.g. longer than eleven hours) electric charging stations with a lower charging capacity should be selected and for short driving breaks (e.g. less than one hour) electric charging stations with a higher charging capacity should be required and selected.

For example, several electrically powered trucks can be traveling in a convoy. This means that a large number of charging options and electrical charging stations are required. In this case, the driving breaks can be based on the truck that has the lowest current state of charge or the lowest range to be expected. In particular, with the help of the charge management system 5 include a predictive function. This function can be used to detect when an electric charging station is occupied 3 becomes free. If this point in time roughly coincides with the time of arrival of another vehicle, this becomes vacant electric charging station 3 reserved directly for the arriving vehicle. This communication can either be via a central control point, in particular the electronic charge management system 5 , or via a direct data exchange between the electrically powered truck 1 and its potential electrical charging station 3 . This results in a higher utilization of the electric charging station 3 .

For example, the electric charging station 3 Be part of a rest area. This rest area can, for example, have several electric charging stations 3 or charging stations. It is also conceivable that the electrical charging station 3 has several charging stations. For example, the electric charging station 3 be designed for a single parking space or for multiple parking spaces. In the case of the only parking space, the electric charging station 3 via a short charging cable. Should be the electric charging station 3 be designed for several parking spaces, this has at least one long charging cable which can be passed on as soon as a corresponding electrically operated vehicle has reached a desired state of charge of the respective electrical energy storage device.

For example, the individual electrical charging stations can differ in their maximum charging power. The electric charging stations can be divided into at least two groups, for example. For example, a high charging power can be output in the first group, while a lower charging output can be output in a second group. The electrical charging stations can also be dimensioned with regard to an electrical current and an electrical voltage, so that in some electrical charging stations the electrical current and thus the cable cross-sections of the cables and the required cooling of the electrical charging stations can be reduced. Other electrical charging stations can then also be limited with regard to their voltage, which results in the fact that, in addition to less expenditure on insulation, the electrical charging station is required. One advantage of this differentiated dimensioning of the electric charging stations with regard to the charging capacity is, on the one hand, reduced investment costs and, on the other hand, the higher cost-effectiveness due to the significantly higher number of full load hours compared to normal sized electric charging stations, as every electric charging station 3 the needs of the electrically powered truck 1 can be allocated and customized.

In particular, the maximum charging power of the electric charging station is also available 3 in direct connection with the time until the electrical energy storage 2 is loaded. This loading time should in turn be based on the statutory driving time break. So it makes sense to have an electrically powered truck 1 that does not leave a rest area for a long time (for example, when staying overnight) with a lower charging power. As an incentive to use this lower charging capacity, costs of the charging process can be differentiated, for example. For example, one kilowatt hour or the price of one kilowatt hour can be set higher if the required charging power is higher than for charging processes with lower charging powers. To avoid, for example, the electric charging station 3 , which are the electrically powered trucks 1 has already charged, but is still blocked, for example an additional price per kilowatt hour per unit of time is charged. This price per unit of time is based, for example, on the maximum available charging power of the electric charging station 3 . That means that for a 200 kilowatt electric charging station, for example 3 For example, two euros per hour would be incurred and only 50 cents per hour would be incurred for a 50 kilowatt charging power from an electrical charging station.

Furthermore, in order to avoid that charging stations are booked but not used, a reservation price is charged, which is incurred when the electric charging station is used 3 reserved but not used. This reservation can, for example, be canceled at any time, but the shorter the cancellation, the higher the cancellation costs.

Furthermore, it can also happen that someone has an electric charging station 3 has reserved, but this is blocked by another vehicle because it has exceeded a parking time or charging time for undetermined reasons. In this case, the vehicle can be assigned to a different electric charging station. If this is not possible, the most obvious solution is to contact the driver or the company of the electrically powered truck 1 , which is the electric charging station 3 blocked, to be responsible and that they compensate the other vehicles that need a charging facility. In this case, a kind of contractual penalty can be imposed on the driver of the electrically powered truck 1 , of the downtime at the electric charging station 3 exceeded.

Intelligent charging of the electrically operated truck can also be used 1 can be used to stabilize a regional energy supply network. This can be implemented in such a way that the price per kilowatt hour is adjusted depending on the supply and demand for electricity. So can this electric charging station 3 the electrically powered trucks 1 load dynamically and vary the charging power in order to achieve the minimum total charging price in the overall charging cycle.

In particular, with the help of the charge management system 5 a better utilization of the electric charging stations can be made possible. In addition, network stabilization of an energy network can be provided through intelligent charging. By charging the electrical energy store 2 of the electrically operated truck 1 a battery-saving charging option can also be enabled.
