| 提出一种基于充电损耗与时间综合目标函数的超级电容器最优充电策略，根据预先提取的电容器“阻-流”特性在线确定不同运行条件下的最优充电电流。对Maxwell 2.7 V/10 F超级电容器单体进行测试，以验证所提策略的可行性。在此基础上，以1 kV/6.7 kW·h的超级电容器为例，通过MATLAB仿真定量分析了充电模式、荷电状态区间以及电容器老化对最优充电性能的影响。研究结果表明：所提策略可在超级电容器不同充电模式、荷电状态区间及老化状态下有效提升系统充电效能。 |

| Abstract: |
| An optimal charging strategy for supercapacitors based on the integrated objective function of charging loss and time is proposed. The optimal charging current under different operating conditions is determined online according to the resistance-current characteristics of the capacitor. The Maxwell 2.7 V/10 F supercapacitor is tested to verify the feasibility of the proposed strategy. On this basis, the 1 kV/6.7 kW·h supercapacitor is taken as an example, and the influence of charging mode, state of charge(SOC) interval and capacitor aging on the optimal charging performance is quantitatively analyzed through MATLAB simulation. The results show that the proposed strategy can effectively improve the charging efficiency of the system under different charging modes, SOC intervals and aging states. |
