EV Charging & Grid BufferSystem Harness Solutions
Custom-engineered EV charging HV harness, grid buffer cables, and HVIL safety harness assemblies for DC fast chargers and energy storage systems. Manufactured in China, Thailand, Philippines. IATF 16949 certified quality.
What Are EV Charging & Grid Buffer Harnesses?
EV charging HV harness and grid buffer cables are custom-engineered high-voltage cable assemblies that deliver 1000A+ DC power from battery storage to vehicle charging ports or grid interconnection points. Unlike standard power cables, these assemblies must handle 1500V DC with active thermal management, integrated HVIL safety harness interlocks for personnel protection, and comply with IEC 61851/SAE J1772 charging standards plus utility grid codes.
Our B2B custom manufacturing approach means every harness is engineered specifically for your charger power level and installation environment, from 350kW ultra-fast DC chargers to multi-MW grid buffer systems. We source high-voltage connectors globally and manufacture in Asia (China, Thailand, Philippines) to deliver competitive pricing without compromising safety or reliability.
