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.
