Abstract
An apparatus for protecting a battery pack, includes: a battery module; a relay to apply an output of the battery module to a load of a vehicle, or block the output of the battery module; an actuator to operate by a power supplied from a starter battery; and a processor to: monitor the battery module when a start signal is input to detect a failure of the relay; and if the failure of the relay is detected, control the actuator to discharge the starter battery and block a start of the vehicle.
Claims12
An apparatus for protecting a battery pack, comprising:
- a battery module;
- a relay configured to apply an output of the battery module to a load of a vehicle, or block the output of the battery module;
- an actuator configured to operate by a power supplied from a starter battery external to the battery module and for powering ignition of the vehicle;
- and
- a processor configured to:
- monitor the battery module when a start signal is input to detect a failure of the relay
- if the failure of the relay is detected, control the actuator to discharge the starter battery and block a start of the vehicle,
- wherein, if a failure of the battery module and the failure of the relay is detected, the processor is further configured to maintain an ignition-off state of the vehicle by discharging the starter battery before an ignition of the vehicle is turned on by the start signal.

A method of protecting a battery pack, comprising:
- monitoring, by a processor, a battery module when a start signal is input to detect a failure of a relay;
- applying, by the processor, a control signal to an actuator of a vehicle if the relay fails;
- operating the actuator using power supplied from a starter battery external to the battery module and for powering ignition of the vehicle;
- and
- discharging the starter battery to turn an ignition of the vehicle off,
- wherein to turn the ignition of the vehicle off, the processor maintains an ignition-off state of the vehicle by discharging the starter battery before the ignition of the vehicle is turned on by the start signal.
