Our high-voltage DC contactors are widely used in household energy storage, industrial and commercial energy storage and large-scale grid energy storage systems. Common specifications include 300A/1500Vdc, 500A/1500Vdc and 800A/1500Vdc, suitable for various new energy storage solutions. With the rapid popularization of photovoltaic + energy storage systems, our DC contactors provide efficient and stable current control and protection in application scenarios such as solar energy storage, off-grid/grid-connected energy storage, and grid frequency modulation, helping energy management systems (EMS) improve overall operating efficiency.

In the field of electric vehicles, our low-voltage DC contactors are widely used in electric forklifts, electric logistics vehicles, electric buses, electric trucks and special electric vehicles to ensure safe connection between battery packs and drive systems. DC contactors have high impact resistance, vibration resistance and high reliability, can adapt to complex working conditions, provide stable and reliable power control for new energy vehicles, and help the rapid development of the electric vehicle industry.

Battery Packs Charging

 
The 20A, 50A, and 100A DC contactors we produce are widely used in charging management systems for lithium battery packs, lead-acid battery packs, and other energy storage batteries. During the charging and discharging process of the battery pack, the high-voltage DC contactor undertakes key functions such as current switching, overcurrent protection, and system safety control to ensure the efficient operation of the charging system and extend the battery life. Its stable and reliable performance makes it an ideal choice for applications such as** electric vehicle charging stations, energy storage power stations, and industrial battery management systems (BMS).
