This research addresses the current control of an energy management system (EMS) for reused lithium-ion battery (RLIB). RLIB in parallel with an ultracapacitor (UC) is connected to the dc-link by a dc/dc boost converter. One daily energy consumption of aeration pumps in wastewater treatment plant is illustrated. Aeration pumps use most electricity in the plant. This topology is utilized to enhance the system peak power and reduce the depth of discharge (DoD) of RLIB in the acceleration/deceleration of aeration pumps. The converter used here boosts the voltage of ultracapacitor up to the same level of RLIB side so that their current can be regulated to meet the demand, particularly peak power of pump. Here, the state-space averaging method and Lyapunov stability theory are applied in EMS to manage the power flow between RLIB and UC. For alternatively managing demand load current, switch S1 and S2 is configured between the UC, RLIB and dc-link. EMS is used to carry out the current control between these two switches. A simulation is performed to confirm the effectiveness of the proposed control scheme of EMS. Besides, the comparison of topologies with and without auxiliary switch S2 based on the same load current pattern is also discussed. In conclusion, current control of EMS for RLIB is developed and used in the acceleration/deceleration process of aeration pumps in wastewater treatment.

这项研究针对的是可重复使用的锂离子电池（RLIB）的能量管理系统（EMS）的当前控制。与超级电容器（UC）并联的RLIB通过dc / dc升压转换器连接到dc-link。说明了废水处理厂中曝气泵每天的能耗。曝气泵在工厂中消耗大部分电力。利用这种拓扑结构可以提高系统峰值功率，并减少充气泵加速/减速中RLIB的排放深度（DoD）。此处使用的转换器将超级电容器的电压升至RLIB端的相同水平，从而可以调节其电流以满足需求，特别是泵的峰值功率。在这里，状态空间平均法和李雅普诺夫稳定性理论被应用在EMS中，以管理RLIB和UC之间的功率流。为了交替管理需求负载电流，在UC，RLIB和直流母线之间配置了开关S1和S2。EMS用于执行这两个开关之间的电流控制。进行仿真以确认所提出的EMS控制方案的有效性。此外，还讨论了基于相同负载电流模式的有无辅助开关S2的拓扑比较。总之，目前针对RLIB的EMS控制已得到开发，并用于污水处理中的曝气泵的加速/减速过程。还讨论了基于相同负载电流模式的有无辅助开关S2的拓扑比较。总之，目前针对RLIB的EMS控制已得到开发，并用于污水处理中的曝气泵的加速/减速过程。还讨论了基于相同负载电流模式的有无辅助开关S2的拓扑比较。总之，目前针对RLIB的EMS控制已被开发出来，并用于废水处理中的曝气泵的加速/减速过程。
