The scale of the power battery industry will increase sharply, and the technical bottleneck needs to be broken through

A few days ago, it is predicted that the lithium-ion power battery market is entering a golden period, and by 2017, the scale of the power battery industry will skyrocket to 4 times
the current one.
Under such a leapfrog scale growth, the quality of the battery has become an unavoidable technical point
.

Recently, Beijing issued a document to adjust the warranty of vehicles and power batteries, including a warranty of not less than 5 years or 100,000 kilometers for key components such as power batteries, and adjusted to provide a warranty of not less than 8 years or 120,000 kilometers
.
Shanghai, like Beijing, as the country's leading demonstration city for the promotion of new energy vehicles, is also considering increasing the service life of power batteries, based on the current power battery warranty service standards of various car companies, power batteries can generally run for 5 years and 100,000 kilometers
.
How to break through the technical bottleneck and extend the service life of the battery is a common issue
faced by all battery manufacturers.

The bottleneck of electric vehicles lies in the battery, only the battery power problem is solved, other problems can be solved
.
Under the current technical conditions, changing the charging method of the power battery is a good choice
to extend the battery life.
Over time, the differences in the cells in the battery pack will gradually increase, which will eventually affect the performance of the battery, resulting in rapid decay
of battery performance.
Different charging methods are important factors affecting the performance and service life of single lithium-ion batteries, and the appropriate charging method can not only maximize the battery capacity, but also extend the battery life
