【摘  要】為了評(píng)估動(dòng)力電池用高壓繼電器生命周期內(nèi)老化狀態(tài),確保能及時(shí)維修和檢查高壓繼電器,提出不同時(shí)間窗口內(nèi)電流負(fù)載計(jì)算方法和報(bào)警算法。此算法可以有效統(tǒng)計(jì)繼電器使用周期內(nèi)負(fù)載頻譜,并且已經(jīng)成功實(shí)施到一款高端新能源BMS中。

【關(guān)鍵詞】動(dòng)力電池;高壓繼電器;老化;負(fù)載

【Abstract】In order to evaluate the aging state of high voltage relay used in power battery during its life cycle and ensure timely maintenance and inspection of high voltage relay,current load calculation method and alarm algorithm in different time windows are proposed. This algorithm can effectively count the load spectrum of the relay during its service life and has been successfully implemented in a high-end new energy BMS.

【Key words】power battery;high voltage relay;ageing;load
