Title:
PRESSURE CONTROL SYSTEM AND PRESSURE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/084259
Kind Code:
A1
Abstract:
This pressure control system (15) controls pressure applied to a battery module (2) in which a plurality of battery cells (21) having a solid electrolyte and a negative electrode containing lithium are laminated. The pressure control system (15) comprises a movable end plate (166) for applying pressure to the battery module (2) by pressing the battery module (2) along the lamination direction of the battery cells (21), and a controller (10) for adjusting the pressure value by controlling the movable end plate (166), and in a case in which a battery control system (1) controlling charging/discharging of the battery module (2) is to be stopped, the controller (10) first reduces the pressure to a prescribed pressure, then the battery control system (1) is stopped.
