Consequently, it is usually unavoidable to encounter temperature changes. Hence, an efficient battery thermal management system is required to maintain the appropriate temperature range, minimize temperature gradients, and mitigate the adverse effects of temperature.
Evaluation metrics for batteries temperature prediction and thermal management models To assist the performance of the ML model and its accuracy, it is important to define an evaluation metrics. Sometimes simple methods such as calculating the difference between the actual value and the predicted value is not enough for evaluating the model.
In general, a systematic review of low-temperature LIBs is conducted in order to provide references for future research. 1. Introduction Lithium-ion batteries (LIBs) have been the workhorse of power supplies for consumer products with the advantages of high energy density, high power density and long service life .
It is vital to demonstrate a proper way of processing test data and propose a performance evaluation method for the proposed battery temperature prediction system. First, the system’s performance is evaluated using the test data collected at various ambient temperatures ranging from 10 °C to 30 °C for a fresh cell under the WLTP test profile.
Machine learning provides strong information-processing algorithms that can model, optimize, predict, and control battery applications. There is no perfect ML technique for battery temperature prediction and thermal management.
Although many efforts have been made in the research of low-temperature batteries, some studies are scattered and cannot provide systematic solutions. In the future study, high-throughput experiments can be used to screen materials and electrolytes suitable for low-temperature batteries.
