Abstract

A capacitor assisted battery module includes a first diode including an anode and a cathode. A second diode includes an anode and a cathode. The anode of the first diode is connected to the cathode of the second diode at a first node. A first capacitor assisted battery (CAB) block includes a positive terminal, a negative terminal and N CABs, where N is an integer greater than zero. The positive terminal of the first CAB block is connected to the cathode of the first diode. A second capacitor assisted battery (CAB) block includes a positive terminal, a negative terminal and N CABs, wherein the negative terminal of the second CAB block is connected to the anode of the second diode. The negative terminal of the first CAB block and the positive terminal of the second CAB block are connected to a second node.
