Conventional voltage equalizers or equalization chargers, which are used for series-connected energy storage cells to eliminate cell voltage imbalance, consisting of a number of switches or transformers tend to be complex with the number of series connection of the energy storage cells. A novel voltage equalization charger consisting only of capacitors, diodes, and an ac power source is proposed, and its dc equivalent circuit expressed by resistors and a dc power source is derived in this paper. Experimental charge tests demonstrated that series-connected EDLCs could be charged up to the uniform voltage by the proposed equalization charger.
