The electrochemical energy storage technology represented by the lithium ion battery becomes the energy storage technology with the fastest increase of installed capacity in the field of electric power energy storage at present due to the advantages of flexibility and rapidness. Particularly in recent years, with the improvement of the permeability of the electric automobile, the scale effect of the lithium battery is shown, the cost is rapidly reduced, and the effect on the renewable energy consumption and the traffic electrification industrial chain is increasingly important. The market of the electrochemical energy storage industry is increasingly scaled up on a global scale, and the commercialization inflection point is accelerated. The scale crossing development of the electrochemical energy storage machine can greatly promote the high quality of the power grid, and plays an important role in the construction and development of the future power grid.
Under the double thrust of national policy and social development requirements, the electrochemical energy storage market rapidly develops, the total reserve capacity of the lithium ion battery increases year by year, and according to CNESA statistics, the reserve capacity of the lithium ion battery reaches 8454MW by 2019.

In addition, other abnormal conditions of the battery occur, such as the battery generates heat when overcharged, and the heat management needs to be started timely to control the temperature of the battery.
