Sažetak
To ensure operational safety and effective utilization of a battery pack it is important to determine temperature level and temperature distribution across its battery cells. This paper as the first of a series of papers, presents a battery pack segment 1s7p testing environment for the purpose of measuring, not only the temperature of each cell, but also the voltage and current of the entire segment. The segment’s cells are thoroughly monitored with three temperature sensors per cell to get the most accurate thermal distribution available. After developing and building the battery pack segment, it is placed in a temperature controlled test chamber, so it can be tested at different temperature levels. Future articles, will describe the segment’s thermal image during charging and discharging. The goal of this paper is to present the accuracy of this testing environment, this must be done without charging or discharging the segment. It is necessary to measure and calculate the temperature sensor’s characteristics, accuracy and offsets, as well as the monitoring system’s sampling time, lag time and any lag time that is generated in the data processing step. With this information, certain measurement compensations can be made (if necessary) for future tests and experiments.
