Abstract

Claims (19)

1. A battery pack provided to for a vehicle, comprising:

at least one battery module having at least one battery cell;

a relay configured to connect the at least one battery module to a motor of the vehicle; and

a controller connected to the relay and the motor to control the relay and the motor,

wherein, when a temperature of the at least one battery cell of the at least one battery module rises over a predetermined temperature, the controller operates the relay so that the motor idles.

2. The battery pack according to claim 1 , wherein, when the temperature of the at least one battery cell of the at least one battery module rises over the predetermined temperature, the controller closes a switch of the relay.

3. The battery pack according to claim 2 , wherein, when the temperature of the at least one battery cell of the at least one battery module rises over the predetermined temperature, the controller shifts a gear of the vehicle to a neutral mode.

4. The battery pack according to claim 2 , further comprising:

a warning unit configured to transmit a danger signal to a driver of the vehicle.

5. The battery pack according to claim 4 , wherein, when the temperature of the at least one battery cell of the at least one battery module rises over the predetermined temperature, the controller controls the warning unit to send a danger signal to the driver of the vehicle.

6. The battery pack according to claim 5 , wherein the controller shifts a gear of the vehicle to a neutral mode together with operating the warning unit so that the motor idles.

7. The battery pack according to claim 5 , wherein after a preset predetermined time passes from the operation of the warning unit, the controller shifts a gear of the vehicle to a neutral mode so that the motor idles.

8. The battery pack according to claim 1 , further comprising:

at least one external resistor configured to connect the relay and the motor.

9. A control method of a battery pack for a vehicle, comprising:

shifting a gear of the vehicle to a neutral mode, when a temperature of at least one battery cell of at least one battery module rises over a predetermined temperature;

operating a relay connected to the at least one battery module over the predetermined temperature; and

allowing a motor of the vehicle connected to the relay to idle according to an operation of the relay.

10. A vehicle, comprising at least one battery pack according to claim 1 .
