Temperature measurements of Li-ion batteries are important for assisting Battery Management Systems in controlling highly relevant states, such as State-of-Charge and State-of-Health. In addition, temperature measurements are essential to prevent dangerous situations and to maximize the performance and cycle life of batteries.
Although these measurements are useful for quantifying the internal temperature, either specially designed batteries with integrated sensors must be made, or a hole must be drilled into an existing (commercial) battery to insert a sensor.
Sensor assembly process is minimally intrusive and semi-automated. Method presented hold promise to be implemented in battery management systems. Temperature monitoring is important for improving the safety and performance of Lithium Ion Batteries (LIB).
Abstract: 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.
Literature suggests that the optimal temperature range, i.e. an appropriate balance between performance, battery life and safety, lies within approximately 20–40 °C with a maximum temperature gradient of less than 5 °C , , , , , . Note that, however, the operating temperature can be in a range between −30 and 60 °C.
One of these complications is temperature monitoring of a battery. Under extreme conditions, such as over (dis)charge, high current loads or short-circuiting, substantial heat is generated internally. Therefore, monitoring the surface temperature underestimates the maximum temperature of batteries.
