In modern electrical systems, maintaining stable and efficient conductivity is critical to overall performance. From EV battery modules and power distribution units to industrial connectors and high-current interfaces, even minor fluctuations in contact resistance can lead to heat generation, energy loss, and long-term system degradation.

High-current systems demand more than simple mechanical retention. In applications such as EV battery connectors, power distribution modules, industrial power equipment, and high-performance charging interfaces, maintaining stable contact force and electrical continuity under thermal and mechanical stress is critical. Traditional spring designs often struggle in these environments due to force instability, relaxation, or vibration-induced degradation. This is why engineers increasingly turn to canted coil springs for high-current applications.

In high-power EV battery connectors, maintaining stable electrical contact under extreme temperature cycling, vibration, and high current loads is one of the most challenging engineering problems.
