Description:

Sensata SIM series is a kind of active high voltage isolation monitoring device for EV/HEVs capable of operating correctly even when the battery is active, and experiencing large voltage variations, no variations, or even if the battery is not connected. The Sensata SIM product continuously monitors the isolation resistance between a vehicle’s IT (Isolated Terra) power system and chassis for deterioration of isolation and potentially dangerous levels of leakage current. The module detects not only leakages but also capacitively stored energy that could be harmful to human operators.

Unique advantage:

•         Could realize active insulation monitoring

•         ±5% error

•         Response time < 5s

•         Reports isolation resistance in Ω/V

•         Also reports capacitively stored energy

•         Best in class performance during voltage transients

•         Monitor isolation resistance before battery connected

Application:

•         OBC main circuit

•         Charging Pile

Prospect:

With development of 800V system and wide usage of high-speed recharge, the request on insulation monitoring will be harsher in the future. Thus, the active IMD will be widely used by vehicle and charging stations.
