Example Embodiment

[0036] Example 1:

[0037] A vehicle-to-vehicle charging device, such as figure 1and figure 2 shown, where, figure 1 The shown car A is the power supply car, and the B car is the electric car. The vehicle-to-vehicle charging device includes: a vehicle-mounted two-way charger, a charging and discharging connection device and a control box.

[0038] The vehicle-mounted two-way charger is used for charging the power-receiving vehicle or receiving the discharge of the power-supplying vehicle, and the vehicle-mounted two-way charger includes an inverter, a rectifier and a charge-discharge mode control unit, and the inverter is used for converting direct current into alternating current , so as to provide the output electric energy for the on-board bidirectional charger through the battery on the vehicle, the rectifier is used to convert the alternating current into direct current to charge the battery on the vehicle, and the charge-discharge mode control unit is used to control...

Example Embodiment

[0055] Example 2:

[0056] The embodiment of the present invention provides a vehicle-to-vehicle charging method, such as image 3 As shown, the method includes:

[0057] S1. The first on-board two-way charger of the power supply vehicle is connected to the charging and discharging connection device, and sends a CP signal and a CC signal to the second on-board two-way charger of the power receiving vehicle. The CC signal is used for connection confirmation, and the CP signal is used for in control confirmation

[0058] S2. The second on-board two-way charger of the electric vehicle is connected to the charging and discharging connection device, and obtains the CP signal and the CC signal from the charging and discharging connection device. If the CC signal is successfully transmitted, the connection is confirmed, and the electric vehicle starts self-checking;

[0059] S3. After the power supply vehicle is connected to the CC signal line, adjust the amplitude of the CP signal...

Example Embodiment

[0065] Example 3:

[0066] An embodiment of the present invention provides a control box, the control box is arranged on a vehicle-to-vehicle charging and discharging connection device, and the control box is used to access and control the signal sent by the power supply vehicle, and transmit the signal to the power receiving vehicle. vehicle.

[0067] like Figure 4 As shown, car A is the power supply car, and car B is the electric car. The control box is provided with a power supply vehicle interface and an electric vehicle interface, and the control box is also provided with a CP signal detection unit and a CP signal transmission unit, the CP signal detection unit is connected to one side of the power supply vehicle, and the CP signal The sending unit is connected to the side of the receiving train.

[0068] Both the power supply vehicle interface and the electric vehicle interface are provided with a three-phase AC interface, an N line interface, a PE line interface, a ...

Abstract

The invention relates to the field of electronic appliances, and provides a vehicle-to-vehicle charging device and method. The vehicle-to-vehicle charging device comprises a vehicular bi-directional charger, charging and discharging connection devices and a control box, and the vehicular bi-directional charger is used for charging for other vehicles or receiving discharging of the other vehicles.The charging and discharging connection devices are used for connecting a power supplying vehicle and a power receiving vehicle, and an alternating current control switch is arranged on the control box and controls charging current. According to the device, the control box is additionally arranged between the charging and discharging connection devices of the power supplying vehicle and the powerreceiving vehicle, the control box can control connection and disconnection of charging current, the charging current is disconnected when an operator operates the device, and electric shock of the operator is avoided.

Description

technical field [0001] The invention relates to the field of electronic appliances, in particular to a vehicle-to-vehicle charging device and method. Background technique [0002] New energy vehicles are currently a hot spot, and new energy vehicles have attracted widespread attention for their low pollution and energy saving. Electric vehicles are new energy vehicles. Whether electric vehicles use pure electric power or hybrid power, after a period of driving, the battery needs to be charged after the power is exhausted. Therefore electric vehicle wants to popularize, the setting of charging device is indispensable. However, in some cases, the electric car may run out of power before reaching a fixed charging device, and there may not be a fixed charging device nearby, so in such cases, the owner can only find a rescue tow truck to send the electric car to Go to the nearest fixed charging device or use a mobile charging vehicle equipped with a mobile charging pile to char...
