Three taboos of lithium batteries for electric vehicles

There are three main types of lithium batteries for electric vehicles, ternary lithium, which is also a kind of lithium battery that is currently used a lot, lithium iron phosphate and lithium titanate. Among them, lithium titanate is very low in popularity and few people use it. Three taboos of lithium batteries! 1. Temperature, lithium battery is afraid of high temperature. 2. Large 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. This will cause the lithium battery to have too high temperature, too much current and shorter life. There will also be cases of bulging scraps. If your electric car is very powerful and very fast, it is recommended to choose 18650 batteries with 10C current. It is obviously very important to choose a suitable battery! 3. It is fully charged. The full charge of the ternary lithium battery is 4.35V. At present, the protection boards on the market are 4.2V cut-off charging, so many people who buy lithium batteries for electric vehicles say that there is no nominal capacity, but it is just this. The reason is that it is generally better to store the lithium battery of electric vehicles for a long time. A 50/50 TV is better. For example, when you buy a new mobile phone, most of it is powered by 50% of the power. If the battery is fully charged and stored for a long time, the capacity of the lithium battery will decrease. Except for lithium iron phosphate and lithium titanate, these two types can be stored at full power. It should also be noted that a better quality protection board should be selected. The greater taboo of lithium batteries is overshoot and overdischarge, and ternary lithium overdischarge at one time. It will be scrapped, and the overshoot must be scrapped.
