EV Auxiliary Power

Today’s hybrid/electric vehicles (xEV) contain many vehicle sub-systems used to perform various auxiliary tasks. They have been traditionally powered by the 12 V battery, but are migrating to the high-voltage battery bus - typically 48 V, 400 V, or 800 V. These systems are primarily three-phase motor driven loads which can run more efficiently at the higher voltage levels. They can be realized in either high-voltage (400 – 800 V) systems, or in 48 V systems. Some of the auxiliary loads found in a xEV vehicles are: E-supercharger, AC compressor, EPS, roll stabilization, cooling fan, fluid pumps, air conditioning compressor, and PTC heaters.
