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: All state of charge (SoC) estimation algorithms based on equivalent circuit models (ECMs) estimate the open circuit voltage (OCV) and convert it to the SoC using the SoC-OCV nonlinear ...

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.
