Four balancing electrodes are used to compensate the asymmetry and the sensitivity method is used to calculate the balancingvoltage.
在非轴对称的情形下，利用四个平衡电极来进行补偿，并通过灵敏度法来求得四个平衡电压值的大小。

So it is usually needed to connect several diodes in series to endure high voltage stress, but design of balancingvoltage of these diodes is difficult.
通常要用多个高频二极管串联以解决耐压问题，但均压设计较困难。

Further, direct current power supply is utilized to recharge the batteries in parallel connection, thereby increasing the efficiency of balancingvoltage.
