摘要
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.关键词
