A protective member covers the terminal post penetration hole to block debris and welding slag, improving battery cell reliability and safety.

Integrated first and second cell supports cut parts and assembly steps while improving space use and fixing strength in energy storage packs.

A vented cell cover lets pouch cells mount directly in the pack case, improving energy density while directing gas and flame upward.

A stacked cell layout with a straight cooling path improves temperature uniformity, cuts pressure drop, and reduces pump size.

Lid-mounted restricting parts hold electric wires in place inside the housing, preventing interference and improving space use.

An integrated bus bar frame spans multiple pouch-cell assemblies to cut parts and assembly steps while maintaining electrical connection and thermal protection.

A grooved protective layer shields electrode tab burrs to prevent short circuits while limiting thickness growth and preserving energy density.

Sequential pressure relief and buffer chambers channel thermal-runaway gas for controlled release, limiting spread inside the battery pack.

A foldable 800°C-resistant cover shields battery cell terminals and side walls, limiting heat transfer while preserving venting during thermal runaway.

A pressure-sensitive member flips to short-circuit the cell before the vent sheet bursts, limiting electrolyte leakage and explosion risk.

Adhesive or welded joints replace bolts in a battery pack structure, cutting mass and space use while improving vibration and impact resistance.

An integrated terminal insulation seal overlaps the lower plastic part to eliminate gaps, reducing short-circuit risk in columnar batteries.

Movable snap-fit terminal caps guard traction battery pack terminals from inadvertent contact while keeping service access simple.

An inward recessed crimp and sealing gasket create double sealing to prevent electrolyte leakage while improving battery pack fixing stability.

An integrated sealing member and overlapping plastic structure remove terminal-hole gaps to prevent end-wall short circuits and improve sealing.

Multi-rib cross members and cover-wall joints spread impact loads to protect battery cells without enlarging or adding weight to the housing.

Offset primary and secondary vent holes with a porous barrier discharge hot gas while blocking re-entry and delaying thermal propagation.

A moving heat-sealing process improves lid-to-film corner sealing in power storage packages, reducing leaks while keeping assembly controlled.

An axially sliding end cap disconnects and locks battery contacts before removal, preventing short circuits during recycling or replacement.

Partitioned buffering space and a coupling member guide hot gas and flame through a controlled path to cut pressure, cool discharge, and limit spread.

A breaker placed ahead of the fusing unit and an insulated fuse space prevent live exposure, short circuits, and shock during replacement.

A supported insulating member keeps the discharge channel open during thermal runaway so the pressure relief mechanism can vent reliably.

A pack-case discharge path redirects flame and gas to ease pressure buildup, spread heat more evenly, and lower thermal runaway risk.

A protruded pack cover, venting device, and partition walls guide failure gas out of dense battery packs to suppress thermal propagation.

An insulation piece protects the adapter transition region from vibration while helping it melt first to cut current during thermal runaway.

Blocking structures split the battery pack filling space into compartments, improving adhesive uniformity, stiffness, and module-to-case strength.

Holding members joined to the outer case stabilize battery modules, limiting collision damage under vibration and impact.

Thickened rib regions aligned with label openings reinforce cell spacing and frame support to improve battery pack durability.

Chamfered groove corners in a battery end cap spread stress more evenly, protecting the pressure relief zone from impact damage.

Folded guide parts and openings steer hot gas from the cell stack to housing vents, protecting adjacent cells from thermal runaway spread.

A pressure-open vent hole cover releases battery cell gas outward while blocking contaminants and reducing heat spread between adjacent cells.

A cover-mounted engageable element pulls the battery connector free when the housing opens, preventing servicing short circuits and device damage.
