Electric Vehicles (EV) & New Energy

Advanced Switching Solutions for BMS, Charging Piles, and Energy Storage.

Battery Management Systems (BMS)

The safety of modern Electric Vehicles depends on the BMS. High voltage DC contactors are critical components used to switch and protect the main battery charging and discharging lines. They must automatically detect and isolate faults to prevent short circuits and fires.

  • Main Disconnect: Isolating the HV battery pack from the vehicle.
  • Pre-Charge Circuit: Preventing inrush current damage to capacitors.
  • Fast Charging: Managing high current DC charging piles (Superchargers).

Solar Inverters & Energy Storage (ESS)

In photovoltaic systems, relays are used for real-time detection, auxiliary power, and safety disconnection. As solar arrays move to 1500V DC architectures, standard relays arc and fail. MiRelay ceramic contactors use Hydrogen arc extinction technology to safely break these high voltage loads.

EV Auxiliary Control

Beyond the main battery, relays control various subsystems within the vehicle including air conditioning compressors, steering pumps, braking assist, and fluid heaters.

  • Reliability: IATF 16949 certified production.
  • Compactness: High power density to save weight.
