BMS中基于TC265芯片的CAN通信模块设计
Introduction:
Nowadays,theuseofelectricvehicles(EV)hasbecomeincreasinglypopularduetotheireco-friendlinessandcostefficiency.Withtheincreasingdemandforelectricvehicles,ithasbecomeequallyimportanttofocusondevelopingefficientbatterymanagementsystems(BMS)toensurethesafetyandlongevityofthebattery.TheBMSisanelectronicsystemthatmanagesthebatteryofanEV,includingmonitoringthebattery'sstateofhealth(SOH),stateofcharge(SOC),andstateoffunction(SOF)aswellasprovidingprotectionmechanismagainst,overcharge,undercharge,andthermalrunaway.OneofthecriticalcomponentsoftheBMSsystemisthecommunicationmodulethatfacilitatescommunicationbetweenthebatteryandotherelectronicmodules.
