Measurement example

Evaluate battery temperature changes during aging and actual operation. Acquire various data such as temperature, heat flows, and voltage simultaneously to monitor the temperature rise of the cell due to charging and discharging during aging. Wireless connectivity further allows a time-efficient, remote measurement set up.


The modular-based Memory Logger LR8450-01 can be set up to log up to 120 channels of data of cell temperature with plug-in type modules. The usage of wireless modules eliminates the need for long thermocouple wiring and allows to remotely connect with a wireless module in a separate aging chamber away from the main unit. Such a set up also is time-efficient and the overall modular character of the main unit allows to extend the number of channels overall up to 330. Due to excellent reduction of noise effects the LR8450 delivers stable logging, even at high voltages and frequencies making it the ideal device for temperature logging of batteries during charge/discharge aging.
