A Closer Look at the On-Board Charger: The development of the second-generation module for the Chevrolet Volt

Battery-electric vehicles and plug-in hybrid-electric vehicles typically include an on-board-charger (OBC) module. The OBC converts ac power from the electrical grid to dc power that is used to charge the vehicle's propulsion battery. The OBC design supports overall vehicle objectives, including high-efficiency, performance, reliability, utility, and affordability. This article describes General Motor's (GM's) objectives for development of the second-generation (Gen2) OBC introduced in the 2016 Chevrolet Volt.
