A bidirectional on-board battery charger (OBC) is an electric vehicle component that allows charging the vehicle’s battery from the grid while also enabling the battery to supply power back to the grid or external loads. It supports vehicle-to-grid (V2G) and vehicle-to-home (V2H) functionalities, improving energy management and grid stability.

The primary types of bidirectional on-board battery chargers are silicon-based and silicon carbide-based. A silicon-based bidirectional on-board battery charger uses silicon semiconductors to both charge a vehicle battery and feed energy back to the grid or home. It is compatible with various battery types, including lithium-ion batteries, lead-acid batteries, nickel-metal hydride (NiMH) batteries, and solid-state batteries. These chargers support multiple charging technologies, such as alternating current (AC) charging, direct current (DC) charging, wireless charging, and hybrid-ID (Hy-ID) charging. They are applied in electric vehicles (EVs), renewable energy systems, power backup systems, and electricity grid services, serving diverse end users including residential, commercial, industrial, and public charging stations.North America was the largest region in the bidirectional on-board battery charger market in 2025.
