POWER SUPPLY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18582687 titled 'POWER SUPPLY SYSTEM
Simplified Explanation:
This patent application describes a power supply system that includes a battery pack with a solid-state battery cell and a restraining member, along with a battery control device that manages the charging and discharging of the battery pack. The system adjusts the surface pressure on the solid-state battery cell by compressing or restoring the restraining member based on the cell's expansion or contraction during charging or discharging. The battery control device also limits the output opening rate of the battery pack at high temperatures to protect the battery.
- The power supply system includes a battery pack with a solid-state battery cell and a restraining member.

Questions about Power Supply System: 1. How does the restraining member impact the surface pressure on the solid-state battery cell? 2. What factors determine the control start temperature set by the battery control device?
Original Abstract Submitted
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.
