Abstract
A battery power cut off system for a vehicle is provided that improves safety of the vehicle by separately detecting an overcurrent, an abnormal current, and a short current generated due to various causes while a vehicle is driven and cutting off power output from a battery. The system includes a collision sensing unit that detects an impact quantity due to a collision while the vehicle is driven and a battery sensor that detects an output current quantity of the battery. A controller analyzes the impact quantity and the output current quantity of the battery to determine whether a collision current, a short current, and an overcurrent are generated and perform a power cut off control. A switch is configured to cut off the battery power supplied to a large-capacity load element in response to a control signal of the controller.
