【Abstract】The detection of leakage faults inthe high-voltage system of electric vehicle isactualythe testing of thehigh-voltage insulation performanceof electricvehicle.Theonlinemonitoring system forelectricvehiclefaults based onelectromagneticeffectsuseshigh-precision LinearHallEfect Sensor toequivalentlymeasure theleakagecurrentof thehigh-voltagewiring harnessof electricvehicle.Atthesame time，themethod ofsettng threshold values is used as thejudgmentconditionforthelevelof leakagefaults，achievingonlineelectricvehicleofleakageinthehigh-voltage system of electric vehicle and ultimately providing guarantees for human and vehicle safety.
