As per FMVSS 305 specification, at least 500 Ω/V of isolation resistance must be maintained from high-voltage systems to chassis ground. Depending on the leakage current measured, HEV/EV system error-handling functions may be designed to take appropriate actions..
Reliable performance under harsh circuit and environmental distortions is a substantial prerequisite for any device to be used in inverter circuit of the new electric vehicle (EV) cars Gonzalez-Hernando et al. (2019).
Any single point for failure of isolation loss does not have much impact on the operation of the system, but it does become a potential life risk when operators make contact with this high-voltage operating environment.
Due to its bipolar input range, current sensing in both directions is possible. In contrast, voltage monitoring is done via high ohmic voltage dividers to reduce power losses. The measurement signal is only given by the resistance ratio and can be adapted to voltage levels, which can be measured more easily.
