Description
The electric powertrain contains a system that shuts down the high voltage line when the vehicle crashes. The SRS unit sends vehicle crash information to the battery condition monitor module via a dedicated signal line when the SRS unit detects that the vehicle has crashed. When the battery condition monitor module keeps receiving vehicle crash information from the SRS unit for a set time, the battery condition monitor module judges that the crash shut down condition has been met, and shuts down the high voltage contactor.
