Cell Lids/Covers TRIZ Cases

Embedding the collecting member in the insulating end cover enables voltage collection without busbars, preserving energy density and insulation.

A grooved tray, cover cavity, buffer members, and packing belts create a flat, stackable battery pack package that reduces transport collisions.

A tray support groove and lapped cover create a flat, stable battery pack package that improves stacking and reduces transport collisions.

A recessed terminal plate matched to a protruding subplate simplifies prismatic battery assembly while improving fitment and electrical reliability.

Engaging paired mounting portions lets the protection cover pre-assemble to the busbar support, improving battery module assembly reliability.

Interconnector structures improve weld access to battery cell terminals while creating insulated spaces to dissipate heat and release gases.

A lead plate closing part and insulating cover block hot vented matter from reaching the gasket, helping prevent short circuits and cell-to-cell thermal failure.

Partially molded polymer supports insulate and stabilize conductors, enabling flexible battery cell layouts with lower assembly cost.

A weakened film section over the battery cell pressure relief mechanism breaks during thermal runaway, enabling timely venting and lowering explosion risk.

A carbon-nanotube polymer cap plate balances flame retardancy, conductivity stability, strength, and thermal shock resistance in battery cells.

A spaced battery unit on a bearing body avoids frame impact, reducing deformation and explosion risk during transport and use.

A polymer-backed conductor structure simplifies battery cell contacting, improves insulation, and supports more flexible pack layouts.

Roll-formed steel side plates with curved folded portions stiffen long battery modules while saving space and avoiding welding-heavy assembly.

Localized case thickness adds rigidity where cells swell, limiting pack deformation while reducing weight and preserving inner space.

Localized crack mitigation regions in the enclosure flange redirect impact and weld cracks to preserve the sealed battery compartment.

A press-and-rotate locking cover makes battery compartments hard for children to open while allowing adult access to the battery.
