Towing device for electric vehicle
First Claim
1. A towing device for an electric vehicle, which uses a towing vehicle to tow the electric vehicle, the electric vehicle including a high voltage line for supplying power from a storage device to a drive motor via an inverter, a storage device control unit for controlling said storage device, a vehicle control unit for controlling said drive motor and said high voltage line, a low voltage line for supplying power to said inverter, said storage device control unit, and said vehicle control unit, and a communication network for transmitting a signal between said vehicle control unit, said inverter, and said storage device control unit, said towing device comprising:
- a connection tool mounted between said electric vehicle and said towing vehicle and transmitting a towing force of said towing vehicle to said electric vehicle;
a communication cable connected detachably to a connection terminal connected to said communication network and connecting a drive motor prioritization control unit provided in said towing vehicle to said vehicle control unit; and
a power supply cable connected detachably to a power supply terminal connected to said low voltage line and connecting a power source provided in said towing vehicle to said low voltage line.

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.
