The present disclosure relates to a smart battery. The smart battery includes a battery shell, layered cells, a positive electrode, a negative electrode, an embedded multi-source sensor group and an intelligent chip. The smart battery can detect the temperature and the pressure of the core of the battery and the current of the battery in real time by using the intelligent chip and the embedded multi-source sensor group, thereby realizing a real-time monitoring of the working state and safety state of the battery, and improving a safety and the reliability of the battery on the basis of realizing the self-sensing function of the battery. The modification to the conventional battery structure by adding the intelligent chip and the embedded multi-source sensor group makes up the gap in research and development, manufacturing and production of the smart battery on the premise of ensuring that the battery volume remains unchanged.
