Abstract
A battery management system for a vehicle includes a controller programmed to charge a battery at a predetermined charge current. The controller activates an electrical load to discharge the battery for a predetermined time in response to a charge current of the battery becoming less than the predetermined charge current at a predetermined voltage limit. After discharging for the predetermined time, the controller resumes charging at the predetermined charge current. A current magnitude during the discharge and the predetermined time may be based on factors including the predetermined charge rate, a battery temperature, and a charge current magnitude during charging.
