摘要

为了解决梯次电池在风光储电、家庭储电、移动储电等储能领域实际应用中

电池一致性管理的问题

提出一种新型的多模块并联输入串联输出（MPISO）的电池成组拓扑结构。其中

36只单体电池并联组成电池模块;DCDC为一种新型开关电源

可实现双向升降压;电池模块和DCDC组成电源模块;串联电源模块输出端

组成高压系统。基于此拓扑设计一种梯次电池储能系统

并对其进行试验研究

结果表明:储能系统可在各种情况下快速收敛各电源模块荷电状态（SOC）;各电源模块可在线退出系统

且退出并不会对母线电压造成冲击。

Abstract

In order to solve the problem of battery consistency management in the practical application of wind and solar storage

household storage

mobile storage

and other energy storage areas

we have proposed a battery group topology with the multi-module parallel-input and series-output（MPISO）.The battery module consists of 36 single cells in parallel; direct current to direct current converter（DCDC） is a new type of switching power supply

and can achieve two-way bulk and boost; the battery module and a DCDC constitute a power module; a high voltage system is composed of power modules in series.Based on this topology

a second-use battery energy storage system is designed and tested.The results show that the energy storage system can quickly cluster SOCs of power modules in various conditions.As well as the power supply module can exit the system online

and the exit does not impact the bus voltage.
