当能量存储设备（例如双电层电容器）的电池串联连接时，由于各个电池的不均匀特性，导致每个电池中的电压不平衡。在以前的研究中，作者提出了一种新的电池电压均衡电路使用LC串联电路，他们检查了这种电路的有效性。然而，电池电压均衡操作的特性取决于每个电池电压差。因此，所提出的电路具有均衡时间倾向于比具有升压电路的其它电池电压均衡电路长的缺点。本文提出了一种减少均衡时间的方法，该方法使用由线性同余生成器生成的伪随机数序列。所提出的方法可以减少平均均衡时间，而无需添加任何其他有源或无源元件。实验结果验证了该方法的有效性。根据实验结果，提出的均衡时间减少方法减少均衡时间为传统方法的86.5%。
When the cells of energy storage devices such as electric double‐layer capacitors are connected in series, it results in voltage imbalance in each cell because of the nonuniform properties of the individual cells. In a previous research, the authors proposed a novel cell voltage equalization circuit using an LC series circuit, and they examined the effectiveness of this circuit. However, the characteristics of the cell voltage equalization operation depend on each cell voltage difference. Therefore, the proposed circuit has a disadvantage that the equalization time tends to be longer than other cell voltage equalization circuits with a boosting circuit. This paper proposes an equalization time reduction method that uses a pseudo‐random number sequence generated by the linear congruential generators. The proposed method can reduce the average equalization time without adding any other active or passive elements. The effectiveness of the proposed method is verified through the experimental results. According to the experimental results, the proposed equalization time reduction method reduces the equalization time to 86.5% of the conventional method.
