Auxiliary Equipment – powering vehicle support
The change towards an electrified future goes beyond powertrain electrification. After all, a modern car requires a variety of additional e-machines, e.g. for windshield wipers, pumps, or the air-conditioning compressor. In an all-electric vehicle, the performance and efficiency of these e-machines directly influences driving range and experience.
At SEG Automotive, we employ our long time experience in developing automotive e-machines to also offer tailored solutions for auxiliaries. With compact packaging and high flexibility in terms of voltage level and as output power, our e-machines for auxiliaries can cover a wide range of application requirements.
Relay
As a leading manufacturer of Starter Motors, we have been producing reliable relays for decades.
High Voltage relays are needed throughout electric vehicle. In the charging system, for example, or to control auxilliaries.
For this wide variety of applications, we offer reliable relays in the range of 450V to 1.500V and 20A to more than 500A that fulfill the highest safety standards.
