Abstract
A vehicle generally includes a motor that drives wheels of the vehicle, a high voltage battery that supplies electric power to the motor, and an exhaust system that exhausts a gas generated by the high voltage battery from the vehicle. The exhaust system for a battery includes an exhaust fan that exhausts the gas generated by the high voltage battery, a control unit that controls operation of the exhaust fan, and a collision detection unit that detects a collision of the vehicle. The control unit has a structure that operates the exhaust fan when the collision detection unit detects a collision of a vehicle.
Claims2
An exhaust system for a battery in a vehicle which includes a motor that drives wheels of the vehicle, a high voltage battery that supplies electric power to the motor, and an exhaust system that exhausts a gas generated by the high voltage battery from the vehicle, the exhaust system for a battery comprising:
- an exhaust fan that exhausts the gas generated by the high voltage battery;
- a control unit that controls operation of the exhaust fan;
- a collision detection unit that detects a collision of the vehicle;
- a first relay having a first relay switch,
- wherein the control unit has a structure that operates the exhaust fan when the collision detection unit detects a collision of the vehicle, and
- wherein the first relay switch has one end connected to the exhaust fan and has another end connected to a power supply line to which a power supply voltage is always supplied irrespective of a state of an ignition switch, wherein the power supply voltage is supplied to the exhaust fan when a control voltage from the control unit is not applied to a first relay coil and the exhaust fan is operated.
