Many electronic loads in car are 12V driven while today’s battery line has come to a combination of 48V for enhanced bus and additional power efficient supplies, of which in EV/HEV the 48V battery will be charged from high voltage battery pack or traction battery. To fulfill the different voltage buses the 12V-48V bi-directional power conversion is populated in power system in car body and both of the two have isolated or non-isolated DCDC converters down the road which are serving the in field powering on for different functional units’ requirements.
