Contraindications for using lithium batteries in electric vehicles

Electric vehicle lithium batteries are mainly divided into three categories. The first ternary lithium is also the most used lithium battery at present, the second lithium iron phosphate, and the third lithium titanate. Among them, the popularity of lithium titanate is very low, and the people who use it are very low. less. First, Tianneng Chaowei and major manufacturers are basically ternary lithium batteries, during which Tianneng lithium batteries use 18650 lithium batteries, and Chaowei lithium batteries are mainly soft-packed ternary lithium, which belong to ternary lithium batteries. Three taboos of lithium type, 3.7V, and 4.2V rechargeable lithium batteries! At the first temperature, lithium batteries are afraid of high temperatures. The second largest current, for example, the 18650 battery is 3C discharge, your electric car is 8000W, and the battery used is lower than the discharge current of your electric car, which will cause the lithium battery to have too high temperature, too much current and shorter life. There will also be a situation where the bulge is invalid. If your electric car has a very high power and a very fast speed, it is recommended to choose the 18650 battery with 10C current. It is obviously very important to choose the right battery! The third is the full battery storage. The ternary lithium battery is fully charged at 4.35V. At present, the protection boards on the market are all 4.2V and the charging is cut off. Therefore, many people buy lithium batteries for electric vehicles and say that they have no nominal capacity. In fact, For this reason, it is generally best to store lithium batteries for electric vehicles for a long period of time, and it is best to charge 50% of the TV. For example, if you buy a new mobile phone, many of them are powered by 50% of the power. If the full battery storage time is long, the capacity of the lithium battery will be reduced. Lithium iron phosphate and lithium titanate are outside. These two types can be stored at full power. It should also be noted that the protection board of better quality should be selected. The biggest taboo of lithium batteries is overshoot and overdischarge. Ternary lithium can be used in one pass. If it is released, it will be invalidated, and the overshoot must be invalidated as well. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
