Insulation Monitoring for DC Charging Stations | EVSE Safety Standards

The spread of fast charging stations is vital for the extensive adoption of e-mobility. Industry associations, including CHAdeMO and CharIn, encourage interoperability of charging stations and EV/PHEVs. As Electric Vehicle Supply Equipment (EVSE) criteria transition to elevated DC voltages to meet the needs of heavier vehicles, safety has become among the industry’s first priorities.

An Isolation Monitoring Device (IMD) is the device responsible for surveilling for possible electrical hazards in each EVSE. Here, Sensata will discuss the international standards requirements for this safety monitoring function and the efficacy of technologies in meeting these criteria.

Along the way, Sensata will demonstrate how Sendyne’s SIM100MOD isolation monitor accords with the current and changing criteria of international standards.

This white paper, first published in 2019, includes capacitance estimates alongside other performance data for the Sendyne SIM100 Insulation Monitoring Device. Although the specific values and outputs might differ across product groups, these safety and electrical design foundations and guidelines remain appropriate for the whole SIM product group, including the SIM200.
