Abstract: A battery system includes a battery and an ECU. The ECU executes polarization cancellation control for canceling polarization of the battery and calculation processing for calculating SOC of the battery after the polarization cancellation control. When the polarization cancellation control is executed after the battery is discharged, the polarization cancellation control is charging control for charging the battery. When the polarization cancellation control is executed after the battery is charged, the polarization cancellation control is discharging control for discharging the battery.

Abstract: A vehicle includes a battery including an all-solid-state battery configured to be externally chargeable with electric power supplied from outside of the vehicle, a heater configured to heat the battery, and a control device configured to control the heater. The control device controls the heater such that when a predetermined condition related to the external charging is satisfied, the temperature of the battery during execution of the external charging is higher than when the predetermined condition is not satisfied. The predetermined condition includes a condition that an elevation of the vehicle during the execution of the external charging is higher than a predetermined height.
