El Sensata | Sendyne SIM100MLP 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 SIM100MLP 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 resistive leakages but also capacitively stored energy that could be harmful to human operators. Due to a proprietary, patented and patent pending advanced algorithm, the module is capable of detecting all sources of leakage, including multiple, simultaneous symmetrical and asymmetrical faults, as well as resistive paths between the chassis and points in the battery with the same potential as the chassis.

In the case of an isolation fault, the unit identifies the position of the fault in relation to the battery’s terminals.

Battery-connected VX1 (Vp) and VX2 (Vn) voltage inputs can measure ±1.1 kV (max, see ordering options for other ranges) in reference to Chassis (0 V).

Communications are achieved via an isolated CAN 2.0B interface and the unit operates over a wide temperature range of –40 °C to +105 °C/+125 °C without connectors.

CATEGORIAS

• Measures voltage of each battery terminal with refernce to chassis
• Informa el voltaje de la batería
• Reports accurate estimates of the isolation status while the battery is having large voltage variations
• When the battery is not connected or if the battery voltage drops below 15 V, the parallel combination of the two reported isolation resistances (for the high and low sides) is still accurate, as well as the sum total of the reported high and low capacitances
• Medidas y reportes de resistencias de fuga modeladas por modelo adaptados a las normas de seguridad ISO6469-1, FMVSS §571.305 y otras.
• Informa la resistencia de aislamiento calculada en Ω/V según los requisitos de las normas de seguridad.
• Mide e informa el valor de la capacitancia desde cada terminal de la batería al chasis.
• Calcula e informa la energía almacenada por la capacitancia total entre la batería y el chasis.
• Reports uncertainty for all measured and calculated values
• Monitorea continuamente las conexiones de las líneas de detección de voltaje a los terminales de la batería; informa conexiones inadecuadas
• 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
• Proporciona almacenamiento no volátil para el valor del maxVoltaje máximo (de diseño) de la batería (utilizado en los cálculos de la resistencia de aislamiento y la energía almacenada). Si el voltaje real observado de la batería es mayor que el establecido maxVoltaje máximo, el valor más alto se utiliza en los cálculos de la resistencia de aislamiento y la energía almacenada.
• Proporciona almacenamiento no volátil para la calibración de las mediciones de voltaje y otros parámetros; todas las mediciones reportadas tienen sus respectivos parámetros de calibración aplicados automáticamente
• Proporciona una fuente de excitación incorporada galvánicamente aislada e intrínsecamente segura contra fugas.
• A single CAN message provides sufficient information for determination of the safety status of the system
• Initializes in under 6 seconds
• Fast detection of a rapid change in insulation resistance: The SIM100 detects an insulation value change in less than 5 secs
• Warning and Fault alerts provided in the STATUS byte for low insulation resistance values
