Safety for motors,
temperature protection for batteries and connectors

Temperature measurement and overheatingprotection

E-mobility is gaining in importance not only through battery-electric and hybrid passengercars, but also through e-scooters, e-bikes, municipal vehicles and electrically powered forklifts. Microtherm Sentronic has accompanied industry earlybirds in early electrification projects from the outset and has gained extensive experience in the development and manufacture of application-specific temperature management systems.

Electric motors and
charging connectors Temperature sensor



  • Overtemperature protection andtemperature-dependentfunction management for electric motors andcharging connectors
