Description:

The Sensata SIM series is a kind of high-voltage active insulation monitoring device for EVs and EVs, capable of working correctly even when the battery is active, with large voltage changes, no changes, or even when the battery is not connected. The Sensata SIM product continuously monitors the insulation resistance between the vehicle IT system (Isolated Terra) and the chassis for insulation degradation and potentially dangerous levels of leakage current. The module detects not only leaks, but also capacitive stored energy that can be harmful to the human operator.

Unique Advantage:

• Can implement active insulation monitoring

• Error ±5%.

• Response time < 5 s

• Shows insulation resistance in Ω/V

• Also reports on capacitive stored energy

• Best-in-class performance during voltage transients

• Check the insulation resistance before connecting the battery

Application:

• OBC Main Circuit

• Charging pile

Perspective:

With the development of the 800V system and the widespread use of high-speed recharging, the demand for insulation monitoring will become more stringent in the future. Therefore, active IMD will be widely used in cars and charging stations.
