Abstract: This paper presents a double ended forward converter designed to charge small arrays of batteries placed in series and parallel such that high output characteristics of converter is supported. Hybrid charging technique has been used consisting 2 technique namely constant current and constant voltage respectively. This gives insight on influence of different charge profiles on batteries and on their indicators, State of Charge (SOC). The main design step for the Double ended forward converter is presented with the experimental results of the designed converter. The latter used to ensure that the battery cells will operate within their safe limits.

Keywords: State of charge (SOC), Double Ended Forward Converter, Hybrid charging technique, Battery charging.
