METHOD FOR AUTOMATIC ENERGY DISCHARGE OF A BATTERY PACK VIA INTERNAL BATTERY ELECTRONICS POST CRASH EVENT |
摘要 |
A system and method for individually discharging battery cells in a high voltage vehicle battery. The system includes a battery controller that monitors and controls the state-of-charge of each of the battery cells and a cell balancing circuit for maintaining the charge of the cells substantially equal. The controller receives a signal from a vehicle crash detector indicating that the vehicle has been in a crash, and in response instructs the cell balancing circuit to discharge all of the battery cells. |
