One-cable measurement of 500+ temperature points
CSM Computer-Systeme-Messtechnik

Exact knowledge of thermal behavior and temperature curves is particularly important in the development of high-performance high-voltage battery systems. The acquisition of temperatures between cells and other vital points throughout the battery must be carried out safely to protect personnel and equipment. Often this is done at several hundred points simultaneously.

CSM’s HV DTemp measurement system – which will be on display at the expo – was developed for the accurate, digital and thus interference-free acquisition of up to 512 temperature measurement points via a single cable connection to the HV DTemp-P central unit, without modification of the battery housing.

The complete system, which is HV-safe up to 1,000V DC, offers a measurement accuracy of ±0.1°C to ±0.25°C, allowing for exact tracking of temperature curves. The very small temperature sensors can be applied precisely yet flexibly, including using an ultra-thin, flexible circuit that can be customized for specific applications. The robust, compact design allows measurements to be taken at all levels (cell, module and battery). The measurement system is suitable for use on test benches or in vehicles for road tests.
