【Abstract】This study mainly introduces the current situation and main problems of the adhesion detection technology scheme of the main and negative relays in electric vehicles. And it also focuses on the application of a detection scheme for the new main negative relay adhesion in power battery systems. Through appropriate simulation analysis，it can effectively simulate the real operating condition and provide a reference for the development of BMS（battery management system）in electric vehicles.

【Key words】electric vehicle；main negative relay；adhesion detection；simulation analysis

近年來，在“雙碳”政策的落實(shí)與推動(dòng)下，新能源汽車產(chǎn)業(yè)飛速發(fā)展，中國(guó)的新能源汽車總量已突破1300萬(wàn)輛，2022年中國(guó)新能源汽車銷量688.7萬(wàn)輛，同比增長(zhǎng)93.4%，隨著新能源汽車數(shù)量的攀升，汽車的安全問題急需引起重視[1-3]。（剩余2626字）
