AI Technical Summary
Technical Problem
Existing battery packs face safety risks due to uncontrolled thermal events, where high-temperature gases and flames from thermal runaway can cause deformation of the pack case, blocking vent paths and leading to chain reactions and explosions.
Method used
A battery pack design featuring a fixing member interposed between the pack case and the housing to suppress deformation, maintaining a vent space and ensuring safe discharge of gases and flames, using components like springs and elastic pads to manage deformation and insulate against heat.
Benefits of technology
The design effectively prevents and delays thermal runaway by securing a path for venting gases and flames, enhancing safety and reliability by minimizing deformation and maintaining a stable vent space.
