Taboo of Lithium Battery for Electric Vehicle

Nowadays, electric vehicles are becoming more and more high-end and intelligent. The research and manufacture technology of electric vehicle is progressing continuously, and the manufacturing technology of electric vehicle is becoming more and more mature. But there is a disadvantage, but has been restricting the development of electric vehicles, that is, batteries!

As countries around the world to ban fuel car schedule reporting, once again usher in a wave of new energy industry boom. It is expected The lithium battery The future will be widely used in the electric car industry.

Electric cars Lithium electricity Pool is divided into three main categories, the first three Yuan lithium, is also one of the most used lithium batteries, lithium iron phosphate, 2 third lithium titanate, including lithium titanate popularity is very low, very few people use. It can out of AMD and major manufacturers are basically ternary lithium batteries, lithium electricity use is the day18650 lithium batteries, AMD ternary lithium electricity mainly soft package, belong to the ternary lithium type, 3.7 V, charged to 4.2 V.

Lithium battery's three big taboo:

1, temperature, lithium battery was afraid of high temperature.

2, high current, such as 18650 batteries is 3 c discharge, electric cars is 8000 w, you use the batteries is lower than your current electric discharge, it leads to lithium battery temperature is too high, excessive current and short service life, still can appear beat scrap, if your electric power is very big, very fast, advised to choose a 10 c current 18650 batteries, so choose the right batteries obviously is very important!

3, is full of electricity storage, ternary lithium electricity electricity is 4.35 V, full protection plate is currently on the market by charging 4.2 V, so a lot of people buy electric lithium battery all say no nominal capacity is much, in fact, it is for this reason, general storage electric lithium battery for a long time, with less than 50 best TV, for example, if you buy a new phone, many of them are up fifty percent of the electricity. If a full charge storage time long, can let the lithium battery capacity decreases. Except and lithium iron phosphate lithium titanate, the two can be full of electricity storage, also need to pay attention to is to choose a good quality protection board, the biggest taboo is the lithium-ion batteries have crossed, a ternary lithium, burton had put overshoot must bulge is discarded.
