无线充电装置及其电池管理系统设计

Design of Wireless Charging Device and Battery Management System

无线充电技术是一种利用电磁感应(即电感耦合),将电能从供电端递送至用电端的技术.BMS即电池管理系统,是负责处理动力电池组实时状态的重要装置,起到了保护电池组与用电设备的稳定性和安全性的作用.本文设计了无线充电装置的电路及其电池管理系统(BMS),并具备SOC的估算以及电池组保护功能,有效地实现了电池组的主动均衡.通过上位机软件监测电池组的状态信息,结合实验验证了设计的正确性.

Wireless charging technology uses electromagnetic induction(i.e.inductive coupling)to deliver electric energy from the power supply end to the user end.BMS(battery management system)is an impor-tant device to deal with the real-time status of power battery pack,which is responsible for protecting the sta-bility and safety of battery pack and electrical equipment.In this paper,the circuit of wireless charging de-vice and its battery management system(BMS)are designed.It has the function of SOC estimation and bat-tery protection,which effectively realizes the active equalization of battery pack.The correctness of the de-sign is verified by monitoring the state information of the battery pack by the upper computer software and the experiment.
