摘　　要：针对纯电动汽车应用场合电池包内部高压漏电发生绝缘故障的问题,研究了一种可以精确计算绝缘电阻以及故障点位置的测量方法。系统采用MC9S12XDT256单片机为主控芯片,采用新型计算方法,在Simulink/Stateflow中完成逻辑系统建模,通过目标机完成绝缘检测系统的功能实现。系统能在较短时间内监测出电池包内部故障位置处的绝缘电阻值大小及相应的对地短路故障点位置,以保证更高效地实现绝缘监测功能。To solve the problem of insulation fault in the battery pack in the application of pure electric vehicle,a method of measuring the insulation resistance and verifying the location of the fault point is studied.The system uses MC9S12XDT256 MCU as the main control chip,adopts the new algorithm to complete the logic system modeling in the Simulink/Stateflow,and accomplishes the function of the insulation detection system by the target machine.The system can monitor the insulation resistance value and verify the corresponding ground short-circuit fault location in a short time so as to ensure more efficient realization of insulation monitoring.
