New Product Launch | High-Voltage DC Relays: Tailored for EV Charging and Energy Storage

As the global transition toward sustainable energy accelerates, the demand for reliable high-voltage power management has never been greater. We are proud to announce the official launch of our latest innovation: the HVDC (High-Voltage Direct Current) Relay Series. Specifically engineered for the demanding environments of Electric Vehicle (EV) charging stations and Battery Energy Storage Systems (BESS), this new product line represents a significant milestone in our commitment to powering the green energy revolution.

The Heart of High-Voltage Safety

In the world of renewable energy, safety and efficiency are non-negotiable. Our HVDC relays are designed to handle the critical task of circuit switching and protection in high-voltage DC systems. Utilizing advanced ceramic brazing technology and hermetic sealing, these relays ensure that arcs are quickly quenched in a gas-filled chamber, preventing oxidation and ensuring stable contact resistance over thousands of cycles.

Key Technical Highlights

  • Superior Arc Suppression:Features a hydrogen-mixed gas filling and magnetic blow-out technology to safely interrupt high-current DC loads up to 1000V.
  • High Load Capacity:Available in configurations ranging from 50A to 350A, meeting the rigorous requirements of DC fast chargers and large-scale industrial storage.
  • Compact & Lightweight:Despite their heavy-duty performance, the series features a space-saving design, allowing for easier integration into modern, compact charging pile cabinets.
  • Energy Efficient:Optimized magnetic circuit design reduces coil power consumption, enhancing the overall efficiency of the host system.
  • Rugged Reliability:Rated for over 10,000 electrical operations at full load, providing the long-term durability essential for infrastructure projects.

Versatile Applications

Our HVDC Relays are the ideal solution for:
  1. EV Charging Piles:Safeguarding DC fast chargers (Level 3) during the connection and disconnection phases.
  2. Energy Storage Systems (ESS):Managing battery clusters and providing emergency disconnect functions in solar and wind storage facilities.
  3. Electric Vehicles:Serving as the main contactor in the High-Voltage Distribution Box (HVDB).
  4. Industrial DC Power Supplies:Reliable switching for heavy industrial automation and telecommunications.
