Abstract
A vehicle includes an electric machine, a battery, an electrical circuit, an overcharge limit device, and a controller. The electric machine is configured to propel the vehicle. The battery has a plurality of cells and is configured to provide electrical power to the electric machine. The electrical circuit is configured to deliver the electrical power from the battery to the electric machine. The overcharge limit device is configured to individually disconnect each of the plurality cells from the circuit in response to an internal pressure of a respective cell exceeding a pressure threshold. The controller is programmed to, in response to detecting a first set of parameters that are indicative of a first of the cells being disconnected from the electrical circuit via the overcharge limit device, discontinue control the first of the cells.
