The power battery market demand has great flexibility and space. At present, we have mastered the most advanced power battery technology and have the most complete industrial chain in the world. Not only is the technology advanced, but also the cost is low. The technology and cost advantages of China's power battery industry leak detection system can be maintained for a long time. Therefore, China's power battery may have a market that is more than three times the demand for China's new energy vehicles.

Although the United States, Europe and other major automobile markets leak test machine are building local power battery production capacity at full capacity, China's power battery technology and cost advantages will not be weakened, and China's status as the world's major power battery producer will not change.In addition, the estimation of the effective production capacity of power batteries vacuum leak testing is more complicated, and the actual effective production capacity is far lower than the planned construction capacity.

Moreover, the production capacity targets announced by power battery manufacturers have a lot of moisture. This aspect can be simply classified as planning goals and actual development goals. The planning goals are made on the basis of the maximum development possibility, and are mainly used for competition publicity and local preferential policies, while the actual development goals are realistic and must correspond to Specific models and specific power battery specifications. Generally speaking, the development plan within two years is real, and the medium and long-term plans will be adjusted at any time according to the actual market demand.

At least from the current point of view, the advanced production capacity of power batteries is insufficient, and the supply of advanced products helium leak test machine is in short supply. The products of large batteries have already appeared the phenomenon of grabbing goods and queuing up. Outdated production capacity is likely to be eliminated, mortgaged, faced with low-price competition, and faced with products that no one even cares about. The lithium battery industry chain is capital-intensive and technology-intensive, which requires continuous research and development, upgrades, and iterations to maintain product leadership.

Therefore, appropriate overcapacity is a manifestation of the market economy, and advanced production capacity will not face the problem of overcapacity, because the industrial chain updates and iterations are relatively fast, and there are no requirements for the manufacturer's R&D strength, capital strength, and industrial upgrading capabilities. very high.

According to the different discharge methods of the battery, the low-temperature heating technology of the battery can be divided into two types: AC heating and self-heating. The solution of AC heating helium leak test equipment is to use an external voltage boost/step-down circuit to realize the function of high-frequency mutual charge and discharge of the battery cells in the battery pack. Since the battery is mainly ohmic impedance at high frequencies, and the ultra-short charging process makes it difficult for lithium dendrites to occur, this solution can achieve efficient and safe heating performance without a significant decrease in battery life .

This solution is still in the experimental stage. In principle, this solution can achieve high-efficiency low-temperature heating of the battery. For example, the control effect of internal and external temperature difference is better, but more design and verification of hardware circuits and control solutions are still needed.
