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.

Abstract: A vehicle having a traction battery with at least one cell includes a controller coupled to the traction battery and programmed to control charging and discharging of the traction battery in response to detecting lithium plating in the at least one cell indicated by a ratio of differential voltage of the at least one cell as a function of time to cell charging rate of the at least one cell. The ratio may be compared to a threshold associated with current battery state of charge to indicate lithium plating when the ratio is below the threshold. Lithium plating may also be detected based on a measured cell open circuit voltage (OCV) relative to a previously stored OCV value. The measured OCV value may be calculated based on a measured cell voltage and current, and a previously stored cell internal resistance.

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: Vehicles that use electric power as a motive force may use accurate measurements of battery power for numerous purposes, e.g., battery characteristics, state of charge of the battery, travel distance remaining for the vehicle and the like. A traction battery measurement should be taken when the battery is fully relaxed, i.e., the battery is neither being charged nor providing power and a time period thereafter when the battery chemistry reaches a steady state. A controller or methods may determine if the battery is relaxed and if the battery is not relaxed, delay charging or discharging of the traction battery to allow accurate battery capacity determination. The controller may control a battery charger to ensure the battery is fully relaxed before sensing battery characteristics.
