A method and system for monitoring an insulation resistance (IR) of an e-machine includes a bridge circuit arrangement. A voltage across the bridge circuit arrangement is detected. The IR is calculated as a resistance in the bridge circuit arrangement associated with the detected voltage.

System and method for e-machine stator insulation resistance monitoring

Online electrochemical impedance spectroscopy (EIS) circuitry and methods. For mobile installations, such as in a hybrid or electric vehicle, battery management units or battery management systems having EIS circuits can provide additional data regarding the state, health and potential failure of batteries. New topologies for the EIS circuitry are proposed, allowing voltage controlled and current controlled EIS to be performed.
