1battery leakageCommon leaks:1） the seal between the upper cover and the bottom groove is not good or due to collision, and the sealant is cracked;2）the safety valve seeps and leaks;3）Leakage of acid at the terminals;4）other parts showed acid leakage.

Energy is the cornerstone of social science and technology development. At present, with the increasing global pollution, energy conservation and environmental protection has become the top priority of social development.

Lead:In January, the production and sales of new energy vehicles were 91,000 and 96,000 respectively, an increase of 113% and 138% respectively over the same period of the previous year Among them, the production and sales of pure electric vehicles were 67,000 and 75,000 respectively, up 141.

In 2018, China turned from a large lithium salt importing country to a lithium salt exporting country Overall, the sharp increase in China's lithium hydroxide exports is on the one hand the release of China's lithium producer capacity, and on the other hand, the rapid growth in demand for lithium hydroxide overseas.

The technical parameters of UPS power supply are important indicators of the quality of UPS and are the main basis for selection For the UPS power supply to be able to supply the load device with clean and uninterrupted power supply, it is necessary to have a detailed understanding of its performance parameters.

First Overview of the situation1.

In the past 2018, many industry people have seen it as a milestone year for the new energy vehicle market In this year, not only the macroscopic traditional car enterprises opened up the electrification transformation layout, the new energy vehicle policies in the two major markets of China and the United States were adjusted, and the sales on the micro level were greatly increased.

Electric vehicle batteries are generally lead-acid batteries, charging time is generally 8 to 10 hours, should not exceed 12 hours

Lithium batteries can also be divided into two types, the cell voltage is 3.7V each 3.2V, of which 3.2V polymer battery is said to be safer than the other.

During the use of polymer lithium batteries , battery bulging may occur due to excessive charging current, overcharging, etc.
