Product Description
Tingfeng Hardware provides hard-to-make stamped busbar contact springs for energy storage BMS, using copper alloy with tin plating. These flexible connection springs deliver contact resistance ≤10mΩ, rated current 50A–300A, and 0.5–2.0mm elastic travel to absorb charge-discharge thermal expansion. With 16 years of precision manufacturing experience, we understand that energy storage systems demand long-cycle reliability and full lifecycle cost far beyond ordinary consumer electronics — our flexible connection solution is engineered for this commercial logic.
Product Overview
Energy storage batteries undergo significant thermal expansion during charge-discharge cycles, and rigid connection points can loosen or fatigue-fracture over long-term cycling. Our busbar springs provide electrical connections through flexible elastic structures, maintaining stable contact force over a 0.5–2.0mm displacement range — a hard-to-make requirement that many traditional stamping factories struggle to achieve consistently.
On the commercial side, energy storage projects typically have design lives exceeding 10 years and extremely low O&M tolerance. When selecting connection solutions, clients look beyond initial unit price to lifecycle failure risk and maintenance cost. Our 100% contact resistance and elastic travel testing, along with traceable batch management, are designed to reduce long-term O&M uncertainty for our clients.
