This requires a high power battery charger circuit which can operate at universal input voltage and be capable of maintaining the required output voltage and current with low ripple. The topology ...

Abstract: An onboard charger is responsible for charging the battery pack in a plug-in hybrid electric vehicle (PHEV). In this paper, a 3.3-kW two-stage battery charger design is presented for a PHEV ...

Powered by a 6A lithium battery of its own, the 12V smart charger is controlled using a built-in LED display that shows the current, voltage, temperature, battery power, and more in real time.
