Today, electric cars are becoming more advanced and intelligent. The research and manufacturing technology of electric vehicles is constantly improved, and the manufacturing technology of electric vehicles is becoming more and more mature. But there is one drawback that has been holding back the development of electric cars -- the battery!
As countries around the world have a wave of development boom has been released to ban the sale of fuel vehicles, the new energy industry ushered in again. It can be predicted that lithium batteries will be widely used in the electric vehicle industry in the future. The three main categories of lithium for electric vehicles, the first three lithium, is currently the most widely used for lithium batteries, lithium iron phosphate, the second, the third lithium titanate, lithium titanate which is low in popularity, is less used by people. Now the first day, the major manufacturers and AMD basically 3 yuan is mainly lithium battery, lithium days use 18650 battery, lithium original AMD soft pack lithium three yuan, belongs to the 3 yuan lithium type, 3.7V, 4.2V charging.
Lithium-ion battery to use in the three taboos
The first temperature, the lithium battery is afraid of high temperature.
Secondly, high current value, such as 18650, the core is 3C discharge, electric bicycle 800 0W, the use of less than electric bicycle discharge current value, will lead to lithium-ion battery temperature is too high, the current value is too large, the service life is short, or the occurrence of drum packaging waste. If your electric bicycle is very powerful and fast, it is recommended to choose the 10C current value of 18650, which is obviously very important!
The third is full charge storage. The full charging voltage of the ternary lithium battery is 4. 35 volts. Currently, the protection plate on the market is cut off at 4.2 volts. As a result, many people who buy lithium-ion batteries for electric cars say they don't have the much-rated capacity. In fact, that's why. In general, lithium-ion batteries in electric cars last a long time, and half the TV sets are the best. For example, when you buy a new phone, many phones use up 50% of their battery.
If the full charge storage time is long, it will reduce the capacity of the lithium battery. Except for lithium iron phosphate and lithium titanate, these two can be full of electricity storage but also need to pay attention to the choice of good quality protection plate, the lithium battery is the biggest taboo is over rushed over put, three yuan lithium a put will be scrapped, too rushed must be scrapped. Pay attention to these points, your electric car lithium battery lasts five or six years is no problem.
