HV safe Temperature Measurement 
HV safe Temperature Measurement
The CSM HV DTemp measurement system is designed for the digital and precise measurement of up to 512 temperature measurement points via a single cable connection to the HV DTemp Central Unit.
Precise knowledge of thermal behaviour and temperature profiles is an essential prerequisite for the further development of high-performance high-voltage battery systems. For this purpose, temperatures must be measured with several hundred measurement points, even between the cells of the battery.
With the HV DTemp measurement system, such measurements can be easily performed due to the connection via a single digital line into the HV environment and the decentralized control of up to 512 temperature measurement points.
The measurement system consists of three components:
HV DTemp IC Sensors
HV DTemp-Mx Controller
HV DTemp-P Central Unit
The individual components are combined specifically to a complete measurement system for each application.
In addition, the DTEMPconfig conficuration software provides further options for individual configuration, such as the selection and naming of temperature measurement points, the entry of comments, support of device firmware updates and the output of configuration reports.
The HV DTemp measurement system is suitable for all demanding temperature measurements with a large number of measurements points in confined installation spaces. The measurement system can be used to determine temperature profiles between the battery cells, especially in HV batteries, e.g. for the optimization and validation of HV batteries in electric or hybrid vehicles.
It is used for measurements whose requirements are not met by conventional analog measurement systems, in particular for reasons of space and lack of interference immunity. With a high number of temperature measurement points, the transmission of interference-sensitive analog signals proves difficult in mobile applications.
Due to the digital data transmission and the small space requirements of the components of the HV DTemp measurement system even such measurement tasks can be mastered. With the compact and robust design of the IC sensors and the controllers, measurements can be made at all levels (cell level, module level, battery level).
The measurement system is suitable for use on test benches and installed in the vehicle during road tests.
