The iso-BTC provides thermal duty information in real-time, without any need for online calibrations or offline calculations. Operation from -40 oC to 100 oC is possible with pouch, prismatic or cylindrical batteries.
iso-BTC’s are normally paired with a charge/discharge unit to measure the electrical capacity of the cells and help characterize the nature of the cell. An iso-BTC can measure the amount of energy and power generated during the charging and discharging of the cells, while keeping the cell at a constant temperature. Thus, the iso-BTC is performing the battery temperature management task, and the results can be directly applied to real-world examples.
“Battery A” was tested due to its wide availability, durability, and similar design features with other gel batteries. Battery A has a charge capacity of 2.2 Ah, and is comprised of three gel cells that are connected in series, in a common housing with passive charge balancing.
This study aims to highlight how an iso-BTC can help characterize features of Battery A that could be related to the batteries cell’s design, composition, or State Of Health (SOH).
