摘要:

针对高压电池组单体电压检测漏电流大、贮存时间短的问题,提出一种浮地电压检测方案。详细介绍浮地电压检测电路的设计方法,并对蓄电池组的漏电流进行理论计算,单体漏电流由3.3 mA减小至0.83 mA。基于Saber软件搭建仿真平台进行漏电流的仿真,并与计算电流进行对比验证,为后续产品设计提供理论依据。实现了极小漏电流的高压电池单体电压检测,满足了电池组长期运行与贮存的需求。

Abstract:

To address the issues of high leakage current and short storage time in high-voltage battery pack cell voltage detection,a floating ground voltage detection scheme is proposed.The design method of the floating ground voltage detection circuit is introduced in detail,and the leakage current of the battery pack is calculated theoretically,which reduces the individual cell leakage current from 3.3 mA to 0.83 mA.A simulation platform is built using Saber software to simulate the leakage current,and the results are compared with the calculated current for verification,providing a theoretical basis for subsequent product design.This achieves the voltage detection of high-voltage battery cells with minimal leakage current, meeting the requirements for the long-term operation and storage of battery packs.

Key words: high-voltage battery pack, single cell voltage detection, floating ground voltage detection, leakage current
