High Voltage and Current Sensor Module

High Voltage Sensor - Marquardt

• The High Voltage Sensor is designed for precise monitoring and protection of modern high-voltage systems. The compact sensor solution combines four key functions: shunt-based current measurement, voltage measurement, isolation resistance measurement and pyro switch activation.

• Precise and fast current measurement enables reliable monitoring of high currents within the high-voltage system. At the same time, up to eight voltage measurement channels allow multiple points within the system to be monitored. Integrated isolation resistance measurement monitors the electrical insulation between the battery and connected components.

• For additional system safety, the High Voltage Sensor integrates a pyro switch activation function. In the event of a crash or overcurrent, the function can trigger the pyro switch to disconnect the high-voltage system from the power supply.

• The scalable design allows the sensor to be adapted to different system requirements. Communication with other control units is enabled via Private CAN. Depending on the measurement and safety function, the integrated functions achieve automotive functional safety levels up to ASIL D.

• The High Voltage Sensor is particularly suitable for high-voltage battery systems in electric, hybrid and fuel cell vehicles as well as trucks, off-road vehicles and other industrial high-voltage applications.
