Challenges & Solutions
Solving the Complexities of EV & Battery Wiring
High Voltage and Current Transmission
Challenge: EV and battery systems require harnesses to handle up to 800V and high continuous current without overheating.
Solution: We use thick-gauge, high-temp rated cables with insulation and terminal systems designed for HV safety, stability, and minimal power loss.
Limited Space in Battery Packs and EV Platforms
Challenge: Modern EV designs require complex routing in confined areas with tight bend radii.
Solution: We provide ultra-flexible cable assemblies with compact sealing components and optimized harness geometry.
Heat and Vibration Stress
Challenge: Battery environments experience continuous thermal cycling and mechanical vibration, which can cause wire fatigue.
Solution: Our harnesses are tested for vibration resistance, thermal cycling, and are jacketed with abrasion- and heat-resistant materials.
EMI and Signal Interference
Challenge: BMS and EV control systems require accurate data transmission and are sensitive to noise.
Solution: We offer shielded signal cables, twisted-pair layouts, and proper grounding schemes to ensure data integrity.
Connector Reliability under Harsh Use
Challenge: EV connectors undergo repeated mating cycles, exposure to moisture, and high current.
Solution: We source automotive-grade sealed connectors with high mating life and IP-rated environmental protection.
Scaling Production with Evolving Battery Designs
Challenge: Battery module designs and interfaces change frequently in new EV platforms.
Solution: Our agile engineering team supports rapid prototyping, connector changes, and BOM flexibility for fast design adaptation.
