Abstract: Hybrid-electric and pure electric vehicles include a traction battery. During vehicle operation, impedance parameters of the traction battery may be estimated. To ensure accurate estimation results, certain persistent excitation criteria may be met. These conditions may not always be met, in which case active excitation of the traction battery power demand may be initiated. The invocation of active battery excitation may be based on a variability of estimates of a battery parameter and an age of a most recent estimate of the battery parameter. As the variability of the parameter estimates increases, the time between active battery excitation requests may decrease.

Abstract: A battery pack includes a first battery and a second battery connected electrically in parallel and performing charge and discharge, and a heater generating heat. The first battery can perform charge and discharge with a current larger than that of the second battery. The second battery has an electric storage capacity larger than that of the first battery. The heater is placed at a position closer to the first battery than the second battery.
