摘　　要：为了克服超级电容传统充电策略充电时间与电容满充之间的矛盾,提出一种基于超级电容内阻补偿的恒流充电方法,该充电方式能够通过恒流充电达到传统恒流-恒压充电方式的满充效果,同时大大减少充电时间。首先分析了超级电容器充电轨迹优化的原理,然后通过实验对可行性与有效性进行验证,最后进一步采用Matlab仿真分析了不同条件下超级电容器的充电性能。研究结果表明:该方法可在基本不降低充电效率(0.2%)的前提下有效减少超级电容器的充电时间(23.5%)。In order to overcome the contradiction between charging time and full charge for capacitor existing in traditional constant-voltage or constant-current charging strategies,a charging trajectory optimization strategy based on internal resistance compensation is proposed.By appropriately extending constant-current charging time to compensate the influence of internal resistance,the capacitor can be quickly fully charged.This paper first analyzes the principle of supercapacitor charging trajectory optimization,then uses the Matlab to simulate the charging performance of supercapacitor under different conditions,and finally further verifies the feasibility and effectiveness.The results show that this method can be adopted to effectively reduce the charging(23.5%)of ultracapacitors without increasing the charging efficiency(0.2%).
