There Are Three Taboos For The Use Of Lithium Batteries In Electric Vehicles. If You Understand These, Your Lithium Battery Can Last For Five Or Six Years!
Nowadays, electric vehicles are becoming more and more intelligent. The R & D and manufacturing technology of electric vehicles is constantly improving, and the manufacturing process of electric vehicles is becoming more and more mature. But there is a drawback, but has been restricting the development of electric vehicles, that is, batteries!
With the release of the global ban on fuel vehicles, the new energy industry once again ushered in a wave of development boom. It can be predicted that lithium battery will be widely used in the electric vehicle industry in the future. Lithium batteries for electric vehicles are mainly divided into three categories: the first ternary lithium, which is also the most widely used lithium battery, the second lithium iron phosphate and the third lithium titanate. Among them, the popularity of lithium titanate is very low, and few people use it. The first one is that Tianneng Chaowei and other major manufacturers basically provide ternary lithium batteries. Among them, Tianneng lithium batteries use 18650 lithium batteries, while the superwei lithium batteries are mainly soft pack ternary lithium batteries, which are all of the ternary lithium type, 3.7V, full charge 4.2V.
Three taboos of lithium battery!
First temperature, lithium battery is afraid of high temperature.
The second largest current, for example, 18650 cell is 3C discharge, your electric vehicle is 8000w, and the cell used is lower than the discharge current of your electric vehicle, which will cause the lithium battery temperature to be too high, the current to be too large and the life to be short, and the bulge will be scrapped. If your electric vehicle has very large power and very fast speed, it is recommended to select 18650 cell with 10C current, so as to select the right one The core is obviously very important!
The third is full battery storage. The full battery capacity of ternary lithium battery is 4.35v. At present, the protection boards on the market are all 4.2V, so many people buy lithium batteries for electric vehicles and say they don't have the nominal capacity. In fact, that's the reason. It's the best to store lithium batteries for electric vehicles for a long time. For example, when you buy a new mobile phone, many batteries are 50% on Quantity.
If the storage time is long, the capacity of lithium battery will be reduced. With the exception of lithium iron phosphate and lithium titanate, these two kinds can be stored at full power, and we need to pay attention to the selection of high-quality protection plate. The biggest taboo of lithium battery is over flushing and over discharging. Once over discharging of ternary lithium, it will be scrapped, and over flushing will be scrapped. Pay attention to these points. It's OK to use your electric ebike lithium battery for five or six years.
