电池管理系统荷电状态估算策略的设计

以电池管理系统荷电状态为研究对象,主要侧重于设计电池工作过程中真实、显示SOC的估算策略。在估算策略的设计过程中,充分考虑了影响电池管理系统荷电状态的因素。在荷电状态估算算法上采用了安时积分法结合开路电压法,对电池真实SOC进行估算,并增加了小电流修正环节,最后通过Simulink建立电池管理系统荷电状态估算策略模型。

Design of Battery State Estimation Strategy for Battery Management System

This paper takes the state of charge of the battery management system as the research object,and focuses on the estimation strategy of real and display SOC during the design of battery operation.In the design process of the estimation strategy,the factors affecting the state of charge of the battery management system are fully considered.In the state of charge estimation algorithm,the ampere-hour integral is combined with the open-circuit voltage method to estimate the real SOC of the battery,and the small current correction link is added.Finally,the state management estimation model of the battery management system is established by Simulink.
