(first embodiment)

A charging device for an electric vehicle according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 8 .

FIG. 6 is a block diagram showing a schematic configuration of a charging device 1A for an electric vehicle (hereinafter referred to as "charging device 1A"). The charging device 1A includes a charging control section 2 housed in a main body, a display 3, an operation input section 4, a relay R1, a zero-phase current transformer (ZCT) 5, and terminal blocks TB1, TB2.

One end of the power cable CB1 is connected to the terminal block TB1 and the other end is connected to a power connector CN1 adapted to be detachably connected to a power outlet such as a commercial AC power supply (hereinafter referred to as "commercial AC power supply"). One end of charging cable CB2 is connected to terminal block TB2 , and the other end is connected to charging connector CN2 adapted to be detachably connected to charging connector 103 of electric vehicle 100 . It should be noted that the charging connector CN2 is integrally provided with: a gripping portion 110 that is held by the human hand; It is detachably connected to the charging connector 103 . Here, the power cable CB1 includes two power lines L1, L2, and a ground line L3. In addition, the charging cable CB2 includes two power lines L1, L2, a ground line L3, and a signal line for transmitting and receiving signals (so-called CPLT signals) between the charging device 1A and the charging circuit 101 included in the electric vehicle 100.

Two contacts included in the relay R1 are respectively connected to wires connected to corresponding power lines L1, L2 among internal wires connected between the terminal blocks TB1 and TB2. The charging control unit 2 controls the on/off of the contact of the relay R1. When the contacts are turned on, power is fed to the electric vehicle 100 . When the contacts are opened, the electric power fed to the electric vehicle 100 is interrupted. It should be noted that when a charging start signal is input from the electric vehicle 100 to the charging control part 2, the relay R1 having a normally open contact is switched from an open state to a closed state by the charging control part 2, thereby feeding power to the electric vehicle 100.

The zero-phase current transformer 5 is used to detect an unbalanced current generated between the power lines L1 and L2 when a leakage occurs on a wire on the electric vehicle 100 side with respect to the relay R1.

Charging of electric vehicle 100 is controlled by turning on and off relay R1 based on a signal input from charging circuit 101 of electric vehicle 100 via signal line L4 to turn on and off power supply to electric vehicle 100 . When the occurrence of electric leakage is detected based on the output of the zero-phase current transformer 5 in the charging mode, the charging control section 2 turns off the relay R1 to interrupt the power supply to the electric vehicle 100 .

The display 3 includes display lamps such as light emitting diodes. The charging control unit 2 changes the operating state of the display 3 (eg, on, blinking, off) to show various states of the charging device 1A (eg, charging mode, non-charging mode, leakage detection, etc.).

The operation input section 4 is provided to perform operations such as stopping power supply to the electric vehicle 100 . The charging control section 2 performs a given operation in response to an input signal from the operation input section 4 .

Next, the structure of the charging device 1A will be described with reference to FIGS. 1 to 3B . Note that, unless otherwise noted, the up-down and left-right directions are defined as the directions shown in FIG. 1 (state where the charging device 1A is installed on the wall 200 ). Furthermore, the front side is defined as the left side in FIG. 3B , and the back side is defined as the right side in FIG. 3B .

The main body 10 of the charging device 1A is formed into a substantially flat plate shape by using synthetic resin. The main body 10 includes a base 11 attached to a wall 200 of a building; and an elongated box-like body 12 made of synthetic resin and formed with an open back, which is attached to the front of the base 11 .

The base 11 is provided with an insertion hole formed through the base 11 in the front-rear direction. The fixing screws 15 (see FIG. 3B ) penetrating through the insertion holes are screwed into the wall 200 , thereby fixing the base 11 on the wall 200 . Here, the installation part for installing the main body 10 on the installation position mainly includes fixing screws 15 and sockets (not shown) provided in the base 11 for the fixing screws 15 to be inserted through the base 11. .

In the body 12, the charging control section 2, the display 3, the operation input section 4, the relay R1, the zero-phase current transformer 5, and the terminal blocks TB1, TB2 described above as circuit components are housed. The body 12 is attached to the base 11 in a suitable manner. The front lower side of the body 12 is opened in a left-right direction at a central portion thereof to form a receiving groove 13 . A receiving groove 13 into which the charging connector CN2 is partially inserted is provided at a lower portion of the body 12 . In the accommodation groove 13 , the connector holding portion 14 is provided to hold the cylindrical connection portion 111 provided at the tip end of the charging connector CN2 in such a manner that the connection portion 111 is inserted into the connector holding portion 14 . The connector holding portion 14 molded of synthetic resin is formed in a cylindrical shape with one end closed, and holds the charging connector CN2 in a state where the tip end of the connecting portion 111 is inserted into the cylinder. In the bottom surface of the body 12 , insertion holes for respectively passing the power cable CB1 and the charging cable CB2 therethrough are provided on left and right sides of the receiving groove 13 . The power cable CB1 and the charging cable CB2 are inserted into the body 12 through corresponding jacks introduced into the body 12 , and are connected to the terminal blocks TB1 , TB2 housed in the body 12 . In addition, on the front of the main body 12, a plurality of (for example three) light emitting diodes LD1, LD2 and LD3 constituting the display 3, and a plurality of (for example two) control switches SW1 and SW2 constituting the operation input part 4 are arranged side by side. - down direction.

As shown in FIG. 1 , the main body 10 of the charging device 1A having the above configuration is installed on a wall 200 of a building. When the power connector CN1 of the main body 10 is connected to the power socket 201 installed on the wall 200 as well as the charging device 1A, electric power is supplied to the charging device 1A from a commercial AC power supply serving as an external power source. It should be noted that when an external power source (such as a power socket of a commercial AC power source) is provided separately from the charging device 1A, the power connector CN1 may be connected to a socket-type connector provided at one end of a power line 202 extending from the external power source. 203, so that power is supplied from the external power source to the charging device 1A.

When the charging device 1A is not used for charging the electric vehicle 100 , the charging connector CN2 is accommodated in the connector holding portion 14 . If the charging connector CN2 is left on the ground in the non-charging mode, the charging connector CN2 and the charging cable CB2 may be stepped on by a person's foot or a vehicle. However, in this embodiment, the user can store the charging connector CN2 in the connector holder 14 in the non-charging mode. Therefore, this reduces the worry of the charging connector CN2 and the charging cable CB2 being stepped on by a person's foot or a vehicle.

On the other hand, when charging electric vehicle 100 by using charging device 1A, the user first separates charging connector CN2 from connector holding portion 14 and connects it to charging connector 103 of electric vehicle 100 . Subsequently, when electric vehicle 100 is ready to be charged, a charging start signal is output from charging circuit 101 to charging control section 2 . Charging control section 2 switches relay R1 from an open state to a closed state, thereby supplying electric power to electric vehicle 100 . At this time, the charging circuit 101 charges the battery 102 in the electric vehicle 100 . When the charging of the battery 102 is completed, a charging completion signal is output to the charging control unit 2 . When the charging completion signal is input from the charging circuit 101 of the electric vehicle 100, the charging control unit 2 switches the relay R1 from the closed state to the open state to stop the electric power supply to the electric vehicle 100, and simultaneously notifies the user through the display 3 finished charging. If a current leakage occurs on the electric vehicle side in the charging mode, the charging control section 2 may detect the occurrence of the leakage based on the output of the zero-phase current transformer 5 . When electric leakage is detected, the charging control section 2 interrupts the power supply to the electric vehicle 100 by turning off the relay R1. The charging device 1A performs the above operations to charge the electric vehicle 100 .

The charging device 1A of the present embodiment includes the above-described main body 10 having a mounting portion (such as a fixing screw 15 ) for attachment at a mounting position. The main body 10 is provided with: a charging cable CB2 connected to the charging connector CN2, the charging connector CN2 is adapted to be detachably connected to the electric vehicle 100 to be charged; used to control the charging of the electric vehicle 100 connected to the charging connector CN2 and a power cable CB1 connected to a power connector CN1 adapted to be connected to an external power source. Charging device 1A feeds electric power supplied from an external power source via power cable CB1 to electric vehicle 100 via charging cable CB2.

Therefore, since the power connector CN1 for connecting to the external power source is wired to the power cable CB1, even a general user, not an expert, can easily connect it to the external power source. This eliminates the need for electric power distribution work by electricians, thereby enabling reduction of the initial cost of the charging device 1A.

Incidentally, in the charging device 1A of the present embodiment, the power cable CB1 may have an extendable wire W1 (so-called winding wire) as shown in FIG. 4 . The extendable wire W1 is helically curled so as to be extendable, whereby the wire W1 can be extended according to the distance from the used power outlet.

Therefore, by extending the used power cable CB1 , the power connector CN1 can be connected to an external power source located at a distance longer than the length of the shortened power cable CB1 . Also, when not in use, the power connector CN1 is separated from the external power source (power socket 201) and shortened. This makes the power cable CB1 compact, thereby reducing the space for accommodating the power cable CB1. Therefore, the power cable CB1 is prevented from becoming an obstacle when not in use. It should be noted that in the embodiment of FIG. 4, only the power cable CB1 is made extensible, but the charging cable CB2 can be made extensible instead of the power cable CB1, or the power cable CB1 and the charging cable CB2 can be made extensible. Both can be made extensible.

As shown in FIG. 5 , in the charging device 1A of the present invention, a housing portion 16 for accommodating the power cable CB1 and the power connector CN1 may be provided in the main body 10 . The housing portion 16 includes a box body 17 having a box-like shape (the front of which is opened and attached to the lower right side of the main body 10); and a door 18 attached to one side of the opening portion of the box body 17 via a hinge so that The opening of the case 17 is openably closed.

When the charging device 1A is not in use, the user opens the door 18 to house the power cable CB1 and the power connector CN1 in the case 17 . Then, the door 18 is closed so that the power cable CB1 and the power connector CN1 can be stored in the housing part 16 . When using the charging device 1A, the user opens the door 18 to take out the power cable CB1 and the power connector CN1 from the case 17 . Then, the power cable CB1 is connected to, for example, a power outlet, so that the charging device 1A can be connected to an external power source.

Therefore, since the housing part 16 for accommodating the power cable CB1 and the power connector CN1 is provided in the main body 10, the user can accommodate the power cable CB1 and the power connector CN1 in the housing part 16 when not in use. Therefore, the power cable CB1 and the power connector CN1 can be prevented from getting in the way when not in use, thereby improving their operability.

In this embodiment, the wall-mounted charging device 1A is described as an example, but a standing charging device 1B as shown in FIG. 7 may also be used.

The charging device 1B includes a main body 20 erected on the ground. The main body 20 is fixed on the installation position by passing the anchor bolt (not shown) embedded in the foundation through the socket 24 of the installation base 23, and tightening the nut (not shown) to the anchor bolt . Here, the installation part for installing the main body 20 on the installation position includes the insertion hole 24 of the installation base 23 and the like.

The main body 20 has an elongated box-like shape, and the circuit components described in FIG. 6 are accommodated inside the main body 20 . The charging cable CB2 is pulled out through the jack provided on the front of the main body 20, and the charging connector CN2 is wired to the tip end of the charging cable CB2. The power cable CB1 extends from the lower part of the back of the main body 20 . The power connector CN1 is connected to the tip of the power cable CB1. The power connector CN1 is connected to a connector 203 wired to a power line 202 extending from an external power source, or to a power outlet provided in a wall of a building, thereby connecting the charging device 1B to the external power source.

Therefore, the power connector CN1 for connection to an external power source is wired to the power cable CB1 included in the standing charging device 1B. Therefore, even a general user, not an expert, can easily connect the power connector CN1 to an external power source. Therefore, even ordinary users can easily install the standing charging device 1B.

Meanwhile, in the standing charging device 1B, as described in FIG. 4 , the power cable CB1 or the charging cable CB2 can be made extensible, or both the power cable CB1 and the charging cable CB2 can be made extensible. of. When the power cable CB1 is made extensible, it can be conveniently stretched and used according to the distance from the external power supply. In addition, when the charging cable CB2 is made extensible, it can be conveniently stretched and used according to the distance from the electric vehicle. In addition, in the non-charging mode, the power cable CB1 and the charging cable CB2 can be shortened. Therefore, the power cable CB1 and the charging cable CB2 are prevented from being bulky and compactly housed.

As shown in FIG. 8 , a door 21 may be provided at the rear of the main body 20 . Inside the door 21, a housing portion 22 for accommodating the power cable CB1 and the power connector CN1 may be provided. When the user opens the door 21, the casing part 22 is opened. In this state, the power cable CB1 and the power connector CN1 can be taken out from the case portion 22 or housed in the case portion 22 .

A charging device of a second embodiment will be described with reference to FIGS. 9 and 10 . Note that the same reference numerals are assigned to the same components in the charging devices 1A and 1B described in the first embodiment, and redundant descriptions thereof will be omitted.

In the charging devices 1A and 1B of the first embodiment, electric power is supplied from a commercial AC power source. However, in the present embodiment, as shown in FIG. 9 , the charging device 1B receives electric power from an electric vehicle 100A serving as a power supply source (hereinafter referred to as "electric power supply electric vehicle"), and feeds electric power to the electric vehicle to be charged. 100B (hereinafter referred to as "electric power receiving electric vehicle").

The circuit configurations of the charging device 1B and the electric vehicles 100A, 100B will be described with reference to the schematic block diagram shown in FIG. 10 .

As a power cable, the charging device 1B includes a power cable CB3 connected to a power supply electric vehicle in addition to a power cable CB1 connected to a commercial AC power source. It should be noted that the power cable CB3 and the connector CN3 have the same structure as the charging cable CB2 and the charging connector CN2, but the colors and marks are different from the charging cable CB2 and the charging connector CN2 for easy identification.

Furthermore, charging device 1B includes relay R1 , charging control unit 2 , communication unit 6 , DC/AC converter 7 , switching unit 8 , and setting unit 9 .

The setting unit 9 is for the user to switch between a state in which the electric power receiving electric vehicle receives electric power from a commercial AC power source and a state in which the electric power receiving electric vehicle receives electric power from the electric power supplying electric vehicle. The setting portion 9 includes, for example, a slide switch, and is provided on the front surface of the main body 20 as an operation knob.

The charging control unit 2 controls the DC/AC converter 7, the switching unit 8, and a communication unit 6 .

When the switching unit 8 is switched to supply power from the commercial AC power source by the charging control unit 2, the AC power input through the power cable CB1 is output to the relay R1. When the switching portion 8 is switched to supply electric power from the electric power supply electric vehicle by the charging control portion 2 , the DC power input through the power cable CB3 is output to the DC/AC converter 7 .

When DC power (hundreds of DC volts) is input to DC/AC converter 7 through switching section 8, DC/AC converter 7 converts the DC power into AC power (100 to 200VAC) and outputs it to relay R1.

Also, the electric vehicles 100A and 100B include a battery 102 , a charging connector 103 , a charging/discharging circuit 104 , a charging/discharging control circuit 105 , and a communication circuit 106 .

Either one of the charging connector CN2 and the connector CN3 is detachably connected to the charging connector 103 . Here, the charging connector CN2 is provided in the charging cable CB2 extending from the charging device 1B, and the connector CN3 is provided in the power cable CB3 extending from the charging device 1B.

The communication circuit 106 transmits and receives signals between the electric vehicles 100A, 100B and the charging device 1B via the power cable CB2 or the power cable CB3 connected to the charging connector 103 .

The charging/discharging control circuit 105 controls the charging/discharging circuit 104 based on the signal received by the communication circuit 106 from the charging device 1B.

The charging/discharging circuit 104 charges the battery 102 (charging operation) or outputs electric power discharged from the battery 102 to the charging device 1B (discharging operation) based on a control signal from the charging/discharging control circuit 105 . In the charging mode of the battery 102 , the charging/discharging circuit 104 converts AC power (for example, 100 to 200 VAC) input from the charging connector 103 into DC power, and charges the battery 102 . In the discharge mode of the battery 102, the charging/discharging circuit 104 outputs DC power (several hundreds of DC volts) discharged from the battery 102 to the charging device 1B via the charging connector 103.

Now, the charging operation of the electric vehicle using the charging device 1B will be described.

First, a case where the charging device 1B receives power supply from a commercial AC power source and charges the electric vehicle 100B will be described. The user connects the power connector CN1 of the charging device 1B to a power outlet of a commercial AC power source, and connects the charging connector CN2 to the charging connector 103 of the power receiving electric vehicle 100B. Then, by using the setting unit 9, the user switches the charging device 1B to a state where electric power is supplied from a commercial AC power source. At this time, the switching unit 8 is switched by the charging control unit 2 so that the AC power input via the power cable CB1 is output to the relay R1. When the charging control section 2 turns on the relay R1 based on the signal transmitted from the electric vehicle 100B, the AC power input from the commercial AC power supply is fed to the electric vehicle 100B so that the battery 102 is charged/discharged by the charging/discharging circuit 104 of the electric vehicle 100B. Charge. During charging, the charging control section 2 turns on the light emitting diode LD4 provided on the front surface of the main body 20 . Lighting of the light-emitting diode LD4 notifies the user that the power supply is received from the commercial AC power supply and the electric vehicle 100B is being charged. When charging of battery 102 in electric power receiving electric vehicle 100B is completed, a charging completion signal is transmitted from communication circuit 106 to communication unit 6 of charging device 1B. When receiving the charging completion signal via the communication section 6, the charging control section 2 of the charging device 1B turns off the relay R1 and stops the power supply to the electric vehicle 100B. At the same time, the charging control unit 2 turns off the light emitting diode LD4 to notify the user that the charging is completed.

Next, a case will be described where, for example, when a commercial AC power source fails, charging device 1B receives DC power from electric vehicle 100A and charges electric vehicle 100B other than electric vehicle 100A. First, the user connects the power connector CN3 of the charging device 1B to the charging connector 103 of the power supplying electric vehicle 100A, and connects the charging connector CN2 to the charging connector 103 of the power receiving electric vehicle 100B. After connecting charging connector CN2 and power connector CN3 , the user switches charging device 1B to a state where electric power is supplied from electric vehicle 100A by using setting unit 9 . At this time, the switching unit 8 is switched by the charging control unit 2 so that the DC power input via the power cable CB3 is output to the DC/AC converter 7 . When the power receiving electric vehicle transmits a charge start signal to charge control section 2 via communication section 6 , charge control section 2 transmits a discharge start signal to power supply electric vehicle 100A via communication section 6 . Then, the charge control section 2 turns on the relay R1 and starts a DC-AC conversion operation through the DC/AC converter 7 . At this time, in electric power supply electric vehicle 100A, charging/discharging control circuit 105 controls charging/discharging circuit 104 so that it discharges DC power in battery 102 and outputs the DC power discharged from battery 102 to charging device 1B. In charging device 1B, DC power supplied from electric vehicle 100A is output to DC/AC converter 7 through switching portion 8 . The DC power is converted into AC power by the DC/AC converter 7, and then fed to the power receiving electric vehicle 100B via the relay R1. In the electric power receiving electric vehicle 100B, the battery 102 is charged by the charging/discharging circuit 104 . During charging, the charging control section 2 turns on the light emitting diode LD5 provided on the front surface of the main body 20 . Lighting of the light emitting diode LD5 notifies the user that the electric power supplied from the electric vehicle 100A is received and the battery 102 is charged. Subsequently, when the charging of the battery 102 in the electric power receiving electric vehicle 100B is completed, a charging completion signal is transmitted from the communication circuit 106 to the communication section 6 . When receiving the charging completion signal via the communication section 6, the charging control section 2 of the charging device 1B turns off the relay R1, and stops the power supply to the electric vehicle 100B. At the same time, the charging control section 2 outputs a signal to the electric power supply electric vehicle 100A, and stops discharging from the electric vehicle 100A. In addition, the charging control unit 2 of the charging device 1B turns off the light-emitting diode LD5 to notify the user of the completion of charging.

Therefore, in the charging device 1B of the present embodiment, the power connector CN3 is connected to the power supply electric vehicle 100A to feed the power supplied from the power supply electric vehicle 100A to the power reception electric vehicle 100B.

Therefore, since the power connector CN3 of the charging device 1B can be connected to electric vehicles other than the power receiving electric vehicle, the power receiving electric vehicle can receive electric power from the above electric vehicle to charge its own battery.

It should be noted that the charging device 1B of the present embodiment receives DC power from the power supply electric vehicle, but the above electric vehicle may be provided with an AC/DC converter for converting DC power discharged from the battery 102 into AC power, And output it to the charging device 1B. In this case, the charging device 1B can output AC power supplied from the above electric vehicle to the power receiving electric vehicle without modification, whereby the DC/AC converter 7 does not have to be provided in the charging device 1B.

In this embodiment, the standing type charging device 1B is described as an example, but the wall-mounted charging device 1A described in the first embodiment may also receive power supply from the power supply electric vehicle 100A and output it to the power supply An electric vehicle 100B is received.
