新能源发展，大量电池的应用，对废旧电池组的剩余电能回收也提出了挑战。为解决上述问题，本文提出一种基于轨道式MC-WPT(磁耦合无线电能传输)技术的电能回收系统，为废旧电池剩余电能回收提供了一种新的补充方式。该系统在流水线上运输多组废旧电池组的同时将其剩余电能高效传输至电网，提高电能回收利用率。本文通过对传统轨道式MC-WPT耦合机构进行改进，将非轨道端作为电能发射端，轨道作为接收端，设计了系统电路拓扑，建立系统数学模型，仿真分析该种耦合机构形式下系统的传输特性。最后搭建一个电能回收实验平台，在轨道上对四组废旧电池组电能同时回收至电网，系统输入功率为1116.8W，电能回收效率约为82.4%，实验结果验证了系统的可行性与高效性。

The development of new energy and the application of a large number of batteries have also posed challenges to the recovery of residual energy from waste battery packs. To address the above issues, this article proposes an electric energy recovery system based on track type MC-WPT (Magnetic Coupled Wireless Power Transfer) technology, providing a new supplementary method for the recovery of residual electric energy from waste batteries. This system transports multiple sets of waste battery packs on the assembly line while efficiently transmitting their remaining electrical energy to the power grid, improving the energy recovery and utilization rate. This article improves the traditional track type MC-WPT coupling mechanism by using the non-track end as the energy transmitting end and the track as the receiving end. The system circuit topology is designed, a system mathematical model is established, and the transmission characteristics of the system under this coupling mechanism form are simulated and analyzed. Finally, a power recovery experimental platform was built, and four sets of waste battery packs were simultaneously recovered to the power grid on the track. The system input power was 1116.8W, and the energy recovery efficiency was about 82.4%. The experimental results verified the feasibility and efficiency of the system.
