A freely configurable sensor module for current, voltage and temperature

A freely configurable sensor module for current, voltage and temperature

Charge and discharge cycles have an impact on the longevity of lithium ion batteries used in electric vehicles and the ultra-capacitors used for energy storage in photovoltaic systems. 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).

    IVT sensor module

  • 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.

  • Modular system

  • 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. As well as the off-the-shelf products, customers can order specific solutions upon request.

  • Technical data on the IVT Modular:

  • Power supply 7-60 V; 5 V 5-12 V; Current range 150A... 1500A; Extended current range up to 5600 A; Current precision ... 125°C; Temperature measurement resolution 1°C and operating temperature -40...105°C

  • Main Advantages

    Operating range up to 5 kA peak and 1500 A continuous current
  • Interfaces: CAN, SPI
  • Bus bar temperature: up to 105 °C
  • Automotive-qualified
  • Accuracy: 16 bit
  • Up to 3 voltage channels for high voltages up to 800 V

    Using data sheets correctly when selecting resistors.

    When selecting a resistor for your application, there is more to bear in mind than you might think. In order to make a preliminary choice using a product data sheet, developers need certain background information and have to calculate some dimensions themselves. We herewith show how to correctly use a data sheet...

  • Current and voltage measurement in and around hybrid and electric drives

    No matter if you're designing a hybrid, electric or fuel cell powered application - a new development's sustainability always depends on the reliability in every-day use and therefore on controlling its energy flow and consumption permanently. Not every method for measuring current and voltage is able to fulfill each of the difficult requirements. Isabellenhütte has developed the current and voltage measuring module IVT for DC applications in alternative drive concepts based on its experience in the area of car battery management.

     

     

  • Low profile braking resistor, optimized design for high energy to heat conversion

    When designing a motor controller, which has to be as compact as possible, every engineers challenge is to deal with the heat dissipation which is being generated when braking the motor. Using the BRK-series of Isabellenhütte as a braking chopper, you're able to resist high energy loads. It's ideal for use on Inverters, EV pre-charging & current limiting applications.

  • Ideal precision shunt for extreme conditions

    When you're working on the design of a power application for extreme temperature conditions and you'd like to measure voltage or current, you might run into limitations. When the internal temperature of your application is rising, the constant load capacity of your shunt decreases and the long-term stability is put to the test.
