On-Board Charger (OBC)
An On-Board Charger (OBC) is an electrification component in an electric vehicle (EV) or plug-in hybrid electric vehicle (PHEV) that is responsible for charging the vehicle's battery. The OBC is an integrated part of the vehicle and is typically located under the hood or inside the vehicle. It converts alternating current (AC) from a charging station or wall outlet into direct current (DC) and delivers it to the vehicle's battery, allowing the battery to charge.
Ongoing advancements in On-Board Charger technology focus on increasing power density, improving efficiency, reducing size and weight, and supporting higher charging capacities. These developments aim to enhance the overall charging experience, reduce charging times, and promote widespread adoption of electric vehicles.
The On-Board Charger plays a vital role in electric and plug-in hybrid vehicles by converting AC power from the grid into DC power for charging the vehicle's battery. Its efficient power conversion, charging control, and safety features are essential for enabling convenient and reliable charging of electric vehicles.
