Current Conducting Connections TRIZ Cases

Elastic press contact replaces welding for battery temperature sensing, preventing deformation and particles while lowering module assembly cost.

Slits and notches in a battery module busbar disperse swelling stress, prevent rupture, and maintain reliable overcurrent connections.

A smooth wavy weld track avoids inflection and overlap points, improving battery cell weld strength and reducing over-welding risk.

A flexible board with an integrated fuse and displacement coupling cuts battery wiring costs while maintaining connections under thermal expansion.

Segmented non-overlapping conductive adhesive patterns suppress temperature variance in power storage stacks while maintaining stable module joining.

Spark-delay side plates and fire-proof sheets let runaway gas vent quickly while containing sparks and blocking external oxygen.

An insulative sheet with pre-arranged wires replaces injection-molded resin protectors, cutting battery module wiring cost and assembly complexity.

A wraparound insulating member and fixing link to the busbar frame improve cell stack isolation and retention inside the module frame.

Inclined asymmetric bus bar projections absorb cell swelling, prevent plate gaps, stabilize welding, and cut die cost in cell stacks.

A sliding sensing block and integrated bus bar simplify battery module voltage sensing assembly, reducing interference, time, and cost.

Intersecting elastic supports hold bus components and cables in two directions to reduce vibration shake and joint failure in batteries.
