| Abstract: | The effect of capacitance deviation rate on the supercapacitor energy storage module was analyzed,The supercapacitor energy storage was compared before and after voltage balance.The existing voltage balancing methods were discussed.In view of these problems,a simple and practical supercapacitor voltage balancing circuit was designed,and a simulation analysis was carried out.The results show that supercapacitor energy increase 37% after voltage balancing.The circuit can be reached to the voltage balance within 2 s.The accuracy of balance is about 4%.The problem of supercapacitor voltage balancing when it charging can be solved effectively. |
