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.

Abstract: An electrified vehicle includes a drive device including an alternating current motor and an inverter that drives the alternating current motor, a control device that controls the drive device, and a heat transfer device that transfers heat of the drive device to a heating target. When a predetermined heat requirement condition transferred to the heating target is satisfied, the control device executes loss increase control to control the drive device so that the power loss increases compared to a case where the heat requirement condition is not satisfied. When an index value regarding a rotation speed of the alternating current motor is less than a first threshold, the loss increase control includes first control to make a d-axis current of the alternating current motor larger than a reference d-axis current, which is the d-axis current when the heat requirement condition is not satisfied.
