A charging box performs a direct current fast charging (DCFC) session of a recipient by a donor, e.g., during a vehicle-to-vehicle (V2V) charging session, and includes a portable housing, disconnect devices connected to a high-voltage (HV) bus to connect/disconnect respective inlet and outlet charging ports to/from the bus, and multiple 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 HV-LV converter. A communication processing unit (CPU) establishes two-way communication between the donor and recipient. A system controller selectively pre-charges the bus, recharge the energy storage device, and selectively command offloading of a DC charging current from the donor, through the HV-HV converter, and to the recipient.
