The three taboos of using lithium batteries for electric vehicles

Nowadays, electric vehicles are increasingly moving in the direction of high-end intelligence. The development and manufacturing technology of electric vehicles is constantly improving, and the manufacturing process of electric vehicles is becoming more and more sophisticated. However, the electric bicycle lithium battery manufacturer has a drawback, and it has always restricted the development of electric vehicles, that is, the battery!

With the continuous announcement of the ban on the sale of fuel vehicles in various countries around the world, the new energy electric bicycle lithium battery industry has once again ushered in a wave of development. It is foreseeable that lithium batteries will be widely used in the electric vehicle profession in the future.

The electric vehicle lithium battery is divided into three major categories, the top three yuan lithium, is also the most used lithium battery, lithium iron phosphate, third lithium titanate, lithium titanate is very low. There are very few people who use it. At the top of the list, Tianneng Chaowei and the major manufacturers are basically ternary lithium batteries. In the meantime, Tianneng Lithium Battery is 18650 lithium battery, and Chaowei Lithium Battery is mainly soft ternary lithium, all attributed to ternary lithium. Type, 3.7V, fully charged 4.2V.

The three taboos of lithium batteries!

At the top of the list, lithium batteries are afraid of high temperatures.

The second largest current, for example, 18650 battery is 3C discharge, your electric car is 8000W, the battery used is lower than the discharge current of your electric car, which will cause the lithium battery temperature to be too high, the current is too large and the life is shortened. It will also show the situation that the drum kit is invalid. If your electric vehicle is very powerful and very fast, it is recommended to select 18650 batteries with 10C current. It is obviously very important to choose the right battery core!

The third is full power storage, ternary lithium battery full power is 4.35V, now the protection board on the market is 4.2V which when it is over will be cut off charging, so many people buy electric car lithium battery said there is no nominal capacity, in fact, For this reason, it is generally best to store lithium batteries 50-inch TVs for electric vehicles for a long time. For example, if you buy a new mobile phone, many of them are powered by 50%. If the full power storage time is long, the lithium battery capacity will be reduced. lithium iron phosphate and lithium titanate are outside, these two can be fully charged, but also need to pay attention to the selection of better quality protection board, the biggest taboo of lithium battery is overshoot and over discharge, once the ternary lithium over discharge obsolete, and the overshoot must be sterilized.

Pay attention to these points, your electric car lithium battery is no problem for five or six years!
