New energy industry -- car lithium battery solution


In recent years, China's power lithium battery industry has experienced from null to existence, from small to big, from weak to strong development. At present, with the strongly support of national science and technology project, the key technology, the key materials and products research of China’s power lithium battery have made significant progress. Although small capacity power lithium battery technology and products of power type still have some gap compared with abroad technology and products, the large capacity power lithium battery industry has developed at the international leading level. The characteristics of single power battery have been qualified for popularization and application. Power lithium battery industry has entered the key stage of industrial construction and popularization and application. The industrial process of power lithium battery has also been in the international leading position.  

In 2018, the output of China's lithium ion battery market increased by 26.71% year-on-year, up to 102.00 GWh, accounting for 54.03% of the world's output. At present, China has become the world's largest manufacturer of lithium ion batteries. Meanwhile, in 2018, the production of lithium ion batteries increased by 48.57% year-on-year and reached up to 5.2GWh. The production of the energy-storing type lithium ion batteries is expected to reach 6.8GWh in 2019.

Abilities and advantages
Faster input speed

WitJoint Electrical Technology provides a variety of brands/protection levels of high-quality products for new energy industry customers. With years of accumulated experience, we can help you understand and avoid possible errors and unnecessary delays. At the same time, Rockwell's simple programming interface and tags as well as modular programming languages save your debugging time.
