Abstract
When the electric vehicle is to be towed by a towing vehicle, the two vehicles are connected by a connection tool, and a drive motor prioritization control unit is connected to the communication network by a communication cable. Power from a battery is then supplied to the low voltage line by a power supply cable, and the inverter is controlled by a signal from the drive motor prioritization control unit of the towing vehicle.
