Nowadays, electric vehicles are increasingly developing in the direction of high-end intellectualization. The development and manufacturing technology of electric vehicle is progressing, and the manufacturing technology of electric vehicle is becoming more sophisticated. But the lithium battery manufacturer of electric bicycle has a disadvantage, which restricts the development of electric bicycle!
With the continuous announcement of the worldwide timetable for banning the sale of fuel vehicles, the lithium battery industry of new energy electric bicycles has once again ushered in a wave of upsurge. It is foreseeable that lithium batteries will be widely used in electric vehicle industry in the future.
Lithium batteries for electric bicycles can be divided into three main categories. The top three lithium batteries are also the lithium batteries most used by electric bicycle lithium battery manufacturers. The second lithium iron phosphate and the third lithium titanate are the lithium batteries. At present, Tianneng Chaowei and the major manufacturers mainly produce ternary lithium batteries. In the meantime, Tianneng lithium batteries use 18650 lithium batteries. The main type of ultra-Wei lithium batteries is soft-packed ternary lithium, which belongs to the ternary lithium type, 3.7V, and charged 4.2V.
3 Taboos Of Lithium Batteries:
At the top of the list, lithium batteries are afraid of high temperature.
Second, high 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 lead to excessive temperature of lithium batteries, excessive current and shorter life, and will also present a situation of drum waste. If your electric car has a very large power and very fast speed, it is recommended to select 18650 battery with 10C current, so as to select the appropriate electric battery. The core is obviously very important!
Third, overcharge. The Three-Yuan lithium battery is 4.35V. Now the protective panels on the market are 4.2V to cut off charging. So many people buy lithium batteries for electric vehicles that have no nominal capacity. In fact, this is the reason. Generally, long-term storage of lithium batteries for electric vehicles is the best way to store 50% of the TV. For example, when you buy a new mobile phone, many of them are 50% of the power on. Quantity. If the full storage time is long, the lithium battery capacity will be reduced. Lithium iron phosphate and lithium titanate outside, these two can be stored at full power, but also need to pay attention to the selection of better quality protection board, the biggest taboo of lithium batteries is overcharge and overdischarge, lithium ternary overdischarge will be discarded, overcharge will be discarded.
Watch out for these points, your lithium-ion battery for five or six years is no problem!
