Battery average temperature is estimated with online calculated impedance phase. Temperature affects lithium-ion battery performance, health and safety. Therefore, obtaining temperature is quite necessary for battery management system. Impedance is widely adopted and proved to be feasible to estimate temperature.
Then a method, based on electrochemical impedance spectroscopy measurement, has been proposed to estimate the internal temperature of power lithium-ion battery by analyzing the phase shift and magnitude of impedance at different ambient temperatures.
Jilte et al. observed that the localized temperature zone within lithium battery cells is influenced by the module’s position. In certain specific areas of the battery, temperature increases of up to 7 degrees Celsius were recorded, leading to the formation of a temperature gradient and compromising thermal uniformity within the battery cell.
The distribution of temperature at the surface of batteries is easy to acquire with common temperature measurement approaches, such as the use of thermocouples and thermal imaging systems . It is, however, challenging to use these approaches in monitoring the internal temperature of LIBs.
Proper storage of lithium batteries is crucial for preserving their performance and extending their lifespan. When not in use, experts recommend storing lithium batteries within a temperature range of -20°C to 25°C (-4°F to 77°F). Storing batteries within this range helps maintain their capacity and minimizes self-discharge rates.
The interaction between temperature regulation and lithium-ion batteries is pivotal due to the intrinsic heat generation within these energy storage systems.
