Whether a car is a battery electric vehicle (BEV) or plug-in hybrid electric vehicle (PHEV), one critical component is the on-board charger (OBC). This enables the charging of the high-voltage DC battery packs from various electric vehicle service equipment (EVSE) or charging stations. Those range from single-phase Level 1 residential chargers (~3 kW) to multi-phase Level 2 commercial capable of providing up to 22 kW, supporting both 400 and 800 V batteries. Of course Level 3 fast chargers provide a DC voltage direct to the battery, bypassing the OBC. However, a small highly efficient form factor is required to give manufactures the flexibility to place the OBC in different locationss in various models.
