Excerpts from the report

The application of intelligent technology in batteries gives batteries the ability to sense internal/external stimuli and make timely response strategies, improve the adaptability of batteries in multiple application scenarios, and ensure the safe, efficient and stable operation of batteries. Battery intelligence mainly includes three aspects: intelligent perception, intelligent response, and intelligent control, through multi-dimensional perception of information from the internal and external environment, stimulate internal response and external control, and jointly make response decisions.

Intelligent sensing is mainly to obtain the signal change when the battery is stimulated through multi-dimensional sensing technology. Intelligent response is mainly through functional materials to respond to battery-perceived stimuli. Intelligent management and control is mainly through the battery according to the obtained state information for self-diagnosis, adjustment and control. This report mainly introduces the current development of battery intelligent technology in three aspects: intelligent response, intelligent perception, and intelligent control, and further discusses the development trend of battery intelligent technology in the future.
