Temperatures are an important factor for the performance of high-voltage batteries, inverters and electric motors. Here you can find out how temperatures are measured in a high-voltage safe way.
Thermal runaways in the HV batteries of electric and hybrid vehicles can lead to fires that are difficult to extinguish and endanger passenger safety. Extensive testing is required to ensure that HV batteries are designed safely with suitable protective mechanisms. In this application example you will learn how the necessary temperature measurements can be carried out at many points in the battery.
The thermal characterization of high-voltage batteries requires precise temperature measurements down to cell level with a large number of sensors. Only with precise insights in the thermal behaviour of battery cells and the whole system further optimization can be performed. With the HV DTemp measurement system, temperatures on the cell level can be measured with up to 512 sensors on only one sensor cable.
High-voltage batteries play a central role in the development of electric vehicles. Temperature management is one of the key factors for their optimal function, which is why temperature measurements are carried out under different conditions during development and pre-series production. The following example shows how such a temperature measurement can be realized in the high-voltage battery.
