xEV auxiliary systems replace traditional mechanical solutions and improve system efficiency by changing from an engine belt-driven solution to an electric drive solution. Battery electric vehicles (BEVs) do not have a combustion engine, requiring the auxiliary systems to be converted to an electric drive alternative. Hybrids (HEVs) and Plug-in Hybrids (PHEVs) have an internal combustion engine (ICE), but auxiliary systems in these architectures can be more efficient running from the high-voltage battery, rather than the engine belt. While the voltage levels may be different for the design, mild hybrids (MHEVs) have both 12 V and 48 V batteries, allowing larger loads to run from the 48 V power net. This provides benefits from a system efficiency standpoint and can lead to a reduction in wiring size.
In high-voltage systems (BEV, HEV, PHEV) and medium-voltage systems such as MHEV, applications like e-Pump, e-Compressor, e-Cooling Fan, e-Turbo, electronic power steering (EPS), other auxiliary motor inverters, and coolant PTC all address the expanding xEV needs in this space.
