On the road to a greener future

High-voltage contactors for the mobility of tomorrow

The automotive sector is one of the most crucial industries that can help mitigate climate change. While it still contributes significantly to the emission of global greenhouse gases, the transport sector is now also vigorously shifting towards electric vehicles and alternative, fossil-free engines. The stakes for the mobility of tomorrow are high, promising fewer emissions, lower noise levels and, overall, a better quality of life.

However, to achieve comparable power in electric vehicles as in combustion engines, high direct current (DC) voltages are indispensable. Powerful lithium-ion batteries are currently the most used battery-type for electromobility. Schaltbau’s DC contactors play a key role within the safety circuit of electric cars, buses, or commercial vehicles: They reliably disconnect the high-voltage battery from the rest of the vehicle’s electrical system in case of failure, thermal overload or an accident.

Once the battery is disconnected from the vehicle’s electrical system, currents can no longer flow. In an emergency, our solutions therefore ensure safety for passengers, emergency services as well as the vehicle itself.
