Abstract

The invention relates to an intelligent battery. The intelligent battery comprises a battery shell, a layered battery cell, a positive electrode, a negative electrode, an embedded multi-source sensorgroup and an intelligent chip, wherein the battery shell, the layered battery cell, the positive electrode and the negative electrode are arranged on a common battery. According to the intelligent battery provided by the invention, by adopting the intelligent chip and the embedded multi-source sensor group, the core pressure, the core temperature, the current and other working information of the battery can be detected in real time, so that the real-time monitoring of the working state and the safety state of the battery is realized, and the safety of the battery is improved on the basis of realizing the self-sensing function of the battery. Therefore, the use safety and reliability of the battery are improved. Moreover, according to the intelligent battery provided by the invention, the traditional battery structure is modified by adding the intelligent chip and the embedded multi-source sensor group, so that the blank state of research on research on research and development, manufacturing, production and the like of the intelligent battery is filled up on the premise of ensuring that the volume of the battery is not changed.

Description

technical field [0001] The invention relates to the field of batteries, in particular to an intelligent battery. Background technique [0002] The development of new energy vehicles is the only way for China to move from a big car country to a car power, and it is a strategic measure to deal with climate change and promote green development. Developed countries such as Europe, the United States, and Japan have invested heavily and successively released and implemented new energy vehicle development strategies, and increased policy support. In recent years, the development of China's new energy automobile industry has achieved world-renowned achievements and has become an important force leading the transformation of the world's automobile industry. [0003] Compared with other types of batteries, lithium-ion batteries are recognized as the first choice for power batteries for electric vehicles at present and for a long time to come due to their significant advantages of hig...
