Abstract
A converter includes a plurality of switching elements coupled between power signal lines that receive a first voltage from an external power source. The converter includes at least one capacitance, and at least one connector including a first port coupled to the first battery and a first power signal line of the power signal lines, a second port coupled to the second battery and a second power signal line of the power signal lines, and a third port coupled to an output line. The output line is coupled between the first battery and the second battery. The converter includes a resonant circuit coupled to the plurality of switching elements. During a charging mode, the plurality of switching elements, the resonant circuit and the at least one capacitance operate to balance voltages of the first battery and the second battery through the first, second, and third ports.
