For this reason, it is necessary for battery safety and longevity to be able to establish the state of charge (SoC) and the state of function (SoF). Isabellenhütte has a solution to this challenge in the form of the tried-and-trusted IVT sensor module for measuring current, voltage and temperature, which is now available in a modular design enabling customers to select individual components and configure their own made-to-measure IVT in accordance with their specific needs.
For instance, a customer might choose communication between SPI or CAN interfaces, between a sensor module with or without galvanic separation or many other configuration possibilities. As well as the current input, up to three voltage inputs are possible; these can be fitted with input filters. Likewise, customers can choose from three different power supplies. The IVT can be equipped with an optional overcurrent detection facility. The sensor module has a current range of 150 to 1500A and operates from either 7 to 60V, or 5V, or in the 5 to 12V range. The voltage measurement resolution is 5mA to 186mV and the sensor is rated for operation in a temperature range from -40 to 125°C.
