随着新能源技术的发展，越来越多的工程车辆采用的是新能源汽车。由于不同工程车辆使用工况不同，部分车辆电量消耗大，但使用场所受限导致充电困难，而部分车辆电量消耗小并且电池容易补充电量，电池利用效率不高，因此为提高电池的利用效率，可通过车对车充电的方式，利用消耗小的供电车为消耗大的受电车进行充电。With the development of new energy technology, more and more engineering vehicles use new energy vehicles. Due to the different working conditions of different engineering vehicles, some vehicles consume a lot of power, but the limited use places make it difficult to charge, while some vehicles consume little power and the battery is easy to replenish, so the battery utilization efficiency is not high. Therefore, in order to improve the battery utilization efficiency, The vehicle-to-vehicle charging method can be used to charge the power-receiving vehicle with low consumption by using the power supply vehicle with low consumption.
目前实现车对车充电的方式，是通过将充电机接入供电车和受电车之间，利用充电机控制供电车和受电车进行充放电，以将从供电车接收到的直流电转换为交流电，再将交流电转换为可供受电车充电的直流电对受电车进行充电。然而，这种方式需要依赖于充电机的接入，硬件成本高。且充电机通常是固定设置，需要将供电车和受电车移动到充电机所在位置接入充电机后，才能进行车对车充电，同时需要供电车、充电机以及受电车进行三方适配，导致车对车充电的通用性和灵活性差。The current way to realize vehicle-to-vehicle charging is to connect the charger between the power supply vehicle and the electric vehicle, and use the charger to control the power supply vehicle and the electric vehicle to charge and discharge, so as to convert the DC power received from the power supply vehicle into AC power. Then the alternating current is converted into direct current which can be charged by the electric vehicle to charge the electric vehicle. However, this method needs to rely on the connection of the charger, and the hardware cost is high. Moreover, the charger is usually fixed. It is necessary to move the power supply vehicle and the electric vehicle to the location of the charger and connect it to the charger before vehicle-to-vehicle charging can be performed. The versatility and flexibility of car-to-car charging are poor.
针对上述技术问题，本申请实施例由供电车通过直流充电线束的低压线缆，来向受电车发送闭合信号，使受电车根据该闭合信号闭合受电车的充电回路，并通过低压线缆向供电车发送指示受电车的充电回路闭合的反馈信号，使供电车闭合供电车的充电回路，以由供电车通过直流充电线束的高压线缆向受电车供电。从而由供电车和受电车通过直流充电线束自行进行信号传输和充放电控制，无需设置充电机，减少车对车充电所需的硬件成本，提高车对车充电的通用性和灵活性。In view of the above technical problems, in the embodiment of the present application, the power supply vehicle sends a closing signal to the receiving vehicle through the low-voltage cable of the DC charging harness, so that the receiving vehicle closes the charging circuit of the receiving vehicle according to the closing signal, and supplies power to the receiving vehicle through the low-voltage cable. The vehicle sends a feedback signal indicating that the charging circuit of the receiving vehicle is closed, so that the power supply vehicle closes the charging circuit of the power supply vehicle, so that the power supply vehicle supplies power to the receiving vehicle through the high-voltage cable of the DC charging harness. Thus, the power supply vehicle and the electric vehicle receive the signal transmission and charge and discharge control by themselves through the DC charging harness, without setting up a charger, reducing the hardware cost required for vehicle-to-vehicle charging, and improving the versatility and flexibility of vehicle-to-vehicle charging.
