双频分层模块化多层电池均衡器架构

This article presents a dual frequency hierarchical modular multilayer balancer (MMB) architecture capable of performing electrochemical impedance spectroscopy (EIS) and self-heating for battery systems. The MMB comprises two layers of balancing circuits: a cell-level balancer operates at a few MHz with miniaturized size; and a string-level balancer operates at a few hundred kHz to achieve high ef...
