The Sensata | Sendyne SIM100MOD is the first high voltage isolation monitoring / insulation monitoring / IMD device for Electric Vehicles (EV/HEVs) and charging stations capable of operating correctly even when the battery is active, and experiencing large voltage variations. The SIM100MOD continuously monitors the isolation resistance between a vehicle's IT (Isolated Terra) power system and chassis for deterioration of insulation and potentially dangerous levels of leakage current.
Features
• Measures voltage for each battery terminal to chassis
• Reports battery voltage
• Operates normally while the battery is having large voltage excursions and variations
• Measures and reports modeled leakage resistances per model adapted by the safety standards ISO6469-1, FMVSS §571.305 and others
• Reports calculated isolation resistance in Ω/V per requirements of the safety standards
• Measures and reports the value of capacitance from each battery terminal to chassis
• Calculates and reports the energy stored by the total capacitance between the battery and chassis
• Continuously monitors connections of the voltage sense lines to the battery terminals; reports inadequate connections
• Continuously monitors connection of the unit to chassis; reports inadequate connection Provides high immunity to common-mode noise that can be present on the battery terminals
• Provides nonvolatile storage for the value of the maximum (design) voltage of the battery (used in calculations of the isolation resistance and stored energy).
