Hybrid Electric Vehicle (HEV) Stop/Start System  Favorite


This system shuts the engine off instead of idling while burning fuel and restarts it instantly on demand.

Stop/start systems require power electronics that can handle high current during cranking and ensure reliability during engine cycles operating on/off at high temperatures.

Freescale offers 8- and 16-bit MCUs plus analog switches, system basis chips (SBC) and transceivers for the numerous engine stop and start cycles.

The MM912J637 battery sensor fits with the start/stop system to monitor the current, voltage and temperature to inform the energy management system.
