Abstract

A vehicle includes an electric machine, a battery, and a controller. The electric machine is configured to deliver power to wheels to drive the vehicle. The battery has an array of cells that are configured to deliver electrical power to the electric machine. The controller is programmed to, in response to a charge imbalance within the array of cells, simultaneously discharge a number of cells within the array based on a temperature of the controller.
