Pascal Mast, Director Sustainable Technologies at TÜV SÜD, an international testing, inspection, auditing and certification service provider said EV batteries undergo strict testing to ensure their safety and performance before being released on the market, with the battery management system (BMS) being a key focus.
University of Maryland researchers studying how lithium batteries fail have developed a new technology that could enable next-generation electric vehicles (EVs) and other devices that are less prone to battery fires while increasing energy storage.
This indicates that WOA-LSTM has the highest improvement in the safety performance of power batteries and the greatest reduction in maintenance costs. Table 2 compares the safety indicators and probability of battery safety accidents of power batteries using three different models.
With the development of sustainable economy, new energy materials are widely used in various industries, and many cars also adopt new energy power batteries as power sources. However, it is currently not possible to accurately diagnose faults in power batteries, which results in the safety of power batteries not being guaranteed.
Jianle Yu, in Tunnelling and Underground Space Technology, 2023 New energy vehicles (NEV) are different from traditional internal combustion engine vehicles (ICEV), mainly including hybrid electric vehicles, battery electric vehicles (BEV), and fuel cell electric vehicles (FCEV).
Traditional FDM falls far short of the expected results and cannot meet the requirements. Therefore, the fault diagnosis model based on WOA-LSTM algorithm proposed in the study can improve the safety of the power battery of new energy battery vehicles and reduce the probability of safety accidents during the driving process of new energy vehicles.
