Current and voltage measurements on electrical consumers in vehicle power supply systems

The number of electrical and electronic components in vehicles is steadily rising. In order to provide an efficient design of vehicle electronics and electrical systems, precise measurements of current and voltage are essential.

It is important to test current and voltage curves under real operating conditions, already in the development phase. Only then an effective energy management and thus an optimal operation of the vehicle is possible. This includes, for example, a safe interaction of the individual sensors, actuators and electronic control units in operating and stand-by periods. CSM provides compact and robust measurement modules and shunts for precise current and voltage measurements in decentralised measurement applications during driving tests.

Thanks to the protection class IP67, the compact design and the wide operating temperature range from -40 °C to +125 °C, these modules are ideally suited for harsh environment conditions. They can be mounted directly in the engine compartment and thus close to the points of measurement which allows precise measurements with almost no interference. In addition, measurement modules and shunts, on account of their low intrinsic heat generation, offer a high measurement accuracy over the entire ambient temperature range.
