A vehicle-to-vehicle charging box and a method for direct current fast charging using the same are disclosed. The charging box performs a direct current fast charge (DCFC) session of a recipient by a supplier, for example during a vehicle-to-vehicle (V2V) charging session, and includes: a portable housing; a disconnection device connected to a high voltage (HV) bus to connect or disconnect the respective inlet and outlet charging ports with or from the bus; and a plurality of direct current to direct current (DC-DC) converters. A high voltage to high voltage (HV-HV) converter is connected to the bus. An optional high voltage to low voltage (HV-LV) converter may be connected to the HV-HV converter. An optional low voltage (LV) energy storage device is connected to the housing and the HV-LV converter. A communication processing unit (CPU) establishes bidirectional communication between a supplier and a receiver. The system controller selectively pre-charges the bus, recharges the energy storage device, and selectively commands unloading of the DC charging current from the supplier through the HV-HV converter and to the recipient.

    公开了车辆到车辆充电箱以及用于使用其的直流快速充电的方法。充电箱例如在车辆到车辆(V2V)充电会话期间通过供给方执行接收方的直流快速充电(DCFC)会话,并且包括:便携式外壳;断连设备,其连接到高压(HV)总线以将相应的入口充电端口和出口充电端口与总线连接或断连;和多个直流到直流(DC‑DC)转换器。高压到高压(HV‑HV)转换器连接到总线。可选的高压到低压(HV‑LV)转换器可以连接到HV‑HV转换器。可选的低压(LV)能量存储设备连接到外壳和HV‑LV转换器。通信处理单元(CPU)在供给方与接收方之间建立双向通信。系统控制器选择性地对总线进行预充电,对能量存储设备进行再充电,并且选择性地命令DC充电电流从供给方通过HV‑HV转换器并且向接收方的卸载。
