Abstract

This paper describes a “flexbattery” modular battery pack concept that integrates the function of energy storage, active cell balancing, and bidirectional multilevel power conversion.As a result, the flexbattery pack does not have a positive or negative terminal, but terminals that can operate at arbitraryvoltage levels, both positive or negative. Since each connection terminal can generate a variable voltage within a certain range, the system can also supply ac voltage. Therefore, with appropriate control this innovative flexbattery could be directly applied to an electrical motor. Also, the flexbattery pack can be charged from any voltage level within the nominal output range of the pack, both dc or ac. The elementary flexbattery unit is introduced and analyzed together with the operation of a pack. Additionally, the concept has been experimentally verified with a 120 W three-unit, nine-level prototype under both ac and dc operation.
