Abstract: Lithium ion battery state of charge (SOC) is a function of open circuit voltage (OCV). Battery internal diffusion process needs to be nearly completed to be able to measure battery open circuit voltage. The length of the minimum settling time depends on the battery type, usage and temperature. Described are methods to determine electric vehicle battery voltage relaxation time based on battery temperature and usage history.

Abstract: A vehicle includes a traction battery. The vehicle further includes a controller programmed to generate a capacity estimate of the traction battery and, in response to an amount of energy supplied to the traction battery during a charge cycle being less than an estimated amount of energy stored in the traction battery during the charge cycle, detect that the capacity of the traction battery has changed and alter an operating strategy of the traction battery until the capacity estimate is updated.

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.
