Battery power cut off system for vehicle and method thereof

A battery power cut off method for a vehicle, comprising:

• detecting, by a controller, an impact quantity and an output current quantity of the battery applied to the vehicle;
• determining, by the controller, whether the generation of a collision current, a short current, and an overcurrent as an abnormal current is detected by analyzing the impact quantity and the output current quantity of the battery;
• and
• cutting off, by the controller, the battery power supplied to large-capacity loads when at least one of the collision current, the short current, and the overcurrent is detected.

A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:

• program instructions that detect an impact quantity and an output current quantity of the battery applied to the vehicle;
• program instructions that determine whether the generation of a collision current, a short current, and an overcurrent as an abnormal current is detected by analyzing the impact quantity and the output current quantity of the battery;
• and
• program instructions that cut off the battery power supplied to large-capacity loads when at least one of the collision current, the short current, and the overcurrent is detected.
