All-in-One Electromechanical High Voltage Contactor for Electric Vehicles


Introducing E-T-A's electromechanical contactor designed specifically to protect the HV-battery in electric vehicles (EV).

Our HVB10 solution combines protection and switching functions in a single device, eliminating the need for HV fuses and reducing complexity. With autonomous short-circuit and overcurrent protection, our solution ensures unparalleled safety standards while offering the convenience of effortless resetting for minor overcurrents, enabling uninterrupted vehicle operation.

Join us in shaping the future of EV safety and efficiency with E-T-A's electromechanical contractor.

Reduce Vehicle Service Costs

Diagnostic functions for open or closed contacts thanks to reliable, integrated mechanical auxiliary contact.

ADDITIONAL FEATURES

  • Protecting and switching in one device. Integrated, autonomous short-circuit and overcurrent protection. In case of overload, the device trips by itself. A HV fuse is no longer necessary, so you reduce complexity.
  • Overall, less installation space, as components including connection technology are replaced.
  • No coordination effort between contactor and fuse. Safe "All in One" solution!
  • No contamination by pyrotechnics. Air and creepage distances do not have to be extended. In addition, less handling effort! (Storage, production, aftersales, logistics especially air freight).
  • Can be completely reset in the event of a slight overcurrent. The vehicle can drive to the workshop if necessary.

Savings

The HVB10 can save up to 15 components per battery pack:

  • 2 x High Volt Relay
  • 2 x PWM relay current saving modules
  • 1 x Fuse
  • 1 x Pyrofuse
  • 2 x control lines (relay and pyrofuse)
  • 2 x HV busbars
  • 5 x connections between individual components

For a long-haul truck with 10 battery packs, 150 components can be replaced by 15 HVB10s.
