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 measurement points.

The measurement system consists of three components:

HV DTemp IC Sensors

• Up to four IC temperature sensors are combined to form an HV DTemp sensor assembly. The sensors are either arranged individually on an ultra-thin flexible circuit or positioned together on one larger flexible circuit.
• The dimensions of the flexible circuit and the sensor position can be selected according to the measurement task.

HV DTemp-Mx Controller

• The compact HV DTemp controllers are installed decentrally in the HV environment. They provide the power supply for the temperature sensors and acquire up to 64 temperature signals in parallel.
• The power supply of all HV DTemp controllers and the transmission of the measured temperature 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 temperature 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 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.
