It is strictly forbidden to immerse the battery pack in water. Once it enters the water or the water enters the battery, it should be isolated and treated immediately, and professional personnel should be asked to deal with it; it is strictly forbidden to charge the battery pack at a high temperature of over 45°C; it is strictly forbidden to discharge the battery pack at a high temperature of over 60°C Or put it on hold, and keep away from fire, heaters, corrosive items, etc., otherwise it may cause the battery pack to overheat, catch fire or fail to function, shorten its life, or even be dangerous;

The storage temperature is 0°C~40°C (the best storage temperature is 15°C~25°C, dry storage). The performance of the battery pack is affected by the temperature. The most intuitive performance is the change of the battery pack capacity, which is a normal phenomenon.

Lithium-ion battery energy storage technology mainly refers to the storage of electrical energy. The stored energy can be used as emergency energy, and can also be used to store energy when the grid load is low, and output energy when the grid load is high, which can be used to shave peaks and fill valleys to reduce grid fluctuations.

At the recently held forum on "Frontier Technologies and Applications of Power and Energy Storage Batteries", Chen Chunmei, Director of the Automobile Division of the Equipment Industry Department of the Ministry of Industry and Information Technology, revealed that the Ministry of Industry and Information Technology is currently speeding up the drafting and compilation of the "Guiding Opinions on Promoting the Development of the Automotive Power Battery Industry". The "Opinions" will make it clear that by 2025, it will accelerate the construction of the national power battery innovation center, strengthen the upgrade of lithium batteries and the research and development of new system batteries, promote the coordinated development of the industrial chain, strengthen the quality inspection of product safety, and improve the management business system, etc. to formulate further measures.

In the relevant regulations of "Dismantling Specification" and "Remaining Energy Inspection", strict requirements are respectively imposed on the safety, operation procedures, storage and management of waste power battery recycling and utilization. The test procedures such as charge and discharge current discrimination and residual energy test are also stipulated.
