Abstract
Systems or methods for testing performance of an isolation monitor for a vehicle having a high voltage traction battery electrical system isolated from a low voltage electrical system include a device for connecting to an isolation/leakage monitor under test. The device includes a current leakage bus, a current leakage array, and a current leakage destination with associated switching elements automatically controlled by a programmed microprocessor to introduce various leakage impedances to a second voltage source or ground and to evaluate performance of the isolation/leakage monitor under test.
