Electric System

For reliable and efficient support of different coolant circuits in both vehicles with combustion engines and electric vehicles: Bosch electric coolant pumps are used for diverse applications, e.g. to support the heating circuits also in start/stop operation and to cool components such as turbochargers or charge air coolers.

Cost-effective, reliable and safe: Bosch electric switches are available for almost all vehicles while offering versatile activation and deactivation in a broad range of applications which require electrical power.

Ensure excellent operation of engine cooling fan for reliable air flow across the radiator: Bosch engine cooling motors are developed using high quality material and drive the fans electrically via DC brush motors or brushless DC motors.

Cost-effective, reliable and safe: Bosch mechanical switches are available for almost all vehicles while offering versatile activation and deactivation in a broad range of applications.

Reliably perform switching operations in a wide range of vehicles due to a particularly compact design: The Bosch micro relay allows rated switching currents of up to 25 A and has a nominal voltage of either 12 or 24 volts.

Reliably perform switching operations in a wide range of vehicles due to its compact design: The Bosch mini relay allows rated switching currents of up to 75 A and has a nominal voltage of either 12 or 24 volts.

Perform powerful and reliable switching operations in engines, starters and large consumers: The Bosch power relay works with rated switching currents up to 350 A and in case of battery cut-off, with relays up to 3,500 A.
