  • Publication number: 20240297511
    Abstract: A power supply system includes a battery pack including a solid-state battery cell and a restraining member, and a battery control device which controls power on charge and discharge of the battery pack. During a charge of the battery pack, the restraining member is compressed due to expansion of the solid-state battery cell, and a surface pressure applied to the solid-state battery cell is increased. During a discharge of the battery pack, the restraining member is restored due to contraction of the solid-state battery cell, and the surface pressure is decreased. The battery control device performs control to limit an output opening rate of the battery pack in a case where a temperature of the battery pack is equal to or higher than a control start temperature, and sets the control start temperature based on a usage state of the battery pack and a battery state of the battery pack.
