EV Relays (DC Contactors) in Electric Vehicles(HCF Series)

EV Relays (DC Contactors) are already in use in the electric vehicle market. They are now mass-produced to meet the needs of well-known global automotive manufacturers who have built up trust in Hecheng’s products. The high-voltage DC relay, applied to electric vehicles, is installed between the vehicle battery and the inverter to cut off the DC power for charging and discharging the battery. It is also used between the external charger and the vehicle battery.The products applied are General Electric Relay (HCF) series with rated voltage of 450V,800V,1000V and 1500V DC and rated current of 40A~400A.

As the global trend of renewable energy continues to expand, the demand for Hecheng EV Relays (DC Contactors) is expected to grow exponentially. Fast chargers for electric vehicles convert AC to DC to supply power to the vehicle, while high-voltage DC relays are used to supply and disconnect power. eSS is a system that stores power and uses EV Relays (DC Contactors)  between the battery and PCS. EV Relays (DC Contactors) are used to turn on/off solar modules in photovoltaic systems.

Based on its achievements in DC 400V electric vehicles, Hecheng will continue to commercialize EV Relays (DC Contactors)  to DC 1000V and DC 1500V for electric vehicles and chargers, and will continue to be a pioneer in the renewable energy market.

EV Relay (DC Contactors) products manufactured by Hecheng Electric Company have been maturely used in electric vehicle components.
