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