Abstract
A vehicle includes a battery pack with a plurality of battery cells. The battery pack is configured to power an electric machine that propels the vehicle. Cell balancing can take place in which electric energy from one cell is transferred to another cell to balance out the respective charges of the cells. The vehicle includes a receiver configured to receive a wireless signal from a wireless key fob. A controller is programmed to inhibit the cell balancing for a user-defined time period that is initiated in response to the wireless signal being received by the receiver.
