On-Board Charger (OBC)
Installed in PHEV and BEV electric vehicles to convert AC to DC for battery charging
The on-board charger (OBC) is an internal system installed in plug-in hybrid (PHEV) and battery electric vehicles (BEV) to convert alternating current (AC) into direct current (DC) required for battery charging. It plays a crucial role in allowing EVs to charge their high-voltage batteries while parked, ensuring greater driving range through improved battery capacity and energy efficiency.
With battery voltage levels standardizing around 450V, and rising to higher voltages, OBCs help shorten charging times and minimize internal wiring. Whether using AC power at home or public/private charging stations, today's OBCs range from 1kW single-phase to 22kW three-phase converters. These chargers are designed to ensure high efficiency and fast charging, making them an essential component for maximizing vehicle range and performance.
