Battery Management Systems: Accurate State-of-Charge Indication for Battery-Powered Applications describes the field of State-of-Charge (SoC) indication for rechargeable batteries. With the emergence of battery-powered devices accurately estimating the battery SoC, and even more important the remaining time of use, becomes more and more important.
It can be concluded that the presented impedance-based temperature indication methods are valuable tools for temperature monitoring of Li-ion batteries. However, high DC (dis)charge currents, interference from electric components, crosstalk interference, SoC and aging dependencies make it challenging to implement.
Similar to Zhu and colleagues , Schmidt et al. performed impedance-based temperature indication in the relaxation time after current pulses. However, no equations were used for corrections. The obtained impedance-based temperature was directly used as indicator for the internal battery temperature.
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 three are commonly used, the E-type would be very suitable for accurate battery temperature measurements due to the high EMF output, which can also be clearly seen in Fig. 13 b. The EMF measured at the cables can be directly converted to temperature with help of a lookup table or by using a mathematical function.
A number of impedance-based-related temperature indication methods have been presented. For example, Champlin patented a method to determine internal battery temperature by performing EIS measurements and calculating time constants of RC-circuits, accordingly.
