HV DTemp Measurement System

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 or humidity measurement points.

The measurement system consists of three components:

HV DTemp IC Sensors

• The sensors are either arranged individually, as a sensor assembly or for IC temperature sensors on an ultra-thin flexible circuit.
• Since up to four sensors can be connected together to form an assembly, only one cable is required per controller port.

HV DTemp-Mx Controller

• The compact HV DTemp controllers are installed throughout the HV environment. They provide the power supply for the IC sensors and acquire up to 64 temperature or humidity signals in parallel.
• The power supply of all HV DTemp controllers and the transmission of the measured values out of the HV environment is provided via a single HV-safe connection cable.

HV DTemp-P Central Unit

• Up to eight of the HV DTemp controllers can be operated simultaneously on the HV DTemp-P Central Unit via an internal digital measurement bus.
• From the HV DTemp-P Central Unit to the measurement data acquisition system, the values are transmitted via a single digital CAN bus cable, which also contains the power supply for all DTemp components.

The individual components are combined specifically for a complete measurement system for each application.

In addition, the configuration software CSMconfig provides further options for individual configuration, such as the selection and naming of measurement points, the entry of comments, support of device firmware updates and the output of configuration reports.
