ELECTRIFIED VEHICLES, BATTERY SYSTEM ARCHITECTURES, AND CONTROL LOGIC FOR VEHICLE-TO-VEHICLE CHARGING

Abstract: presented are high-voltage (hv) electrical system architectures for vehicle-to-vehicle (v2v) charging of vehicle batteries, methods for making/using such systems, and vehicles equipped with such systems. an hv electrical system for a motor vehicle includes a main hv bus that electrically connects the vehicle's traction motor(s) to the vehicle's battery pack(s), and a charging inlet port that electrically mates with and receives direct-current (dc) power from dc fast-charging (dcfc) cables of a donor vehicle and a charging station. a dc-to-dc (dc-dc) converter is interposed between and electrically connects the charging inlet port to the main hv bus. the dc-dc converter is operable in a bypass mode, in which the dc-dc converter passes therethrough dc power received from the dcfc cable of the charging station, and a vehicle-to-vehicle (v2v) mode, in which the dc-dc converter modulates dc power received from the dcfc cable of the donor vehicle.
