Approximately how long is the life of lithium-ion batteries for electric vehicles?

After taking the above 10 measures, lithium-ion batteries can double their service life. Do you use electric vehicles every day and know how long the life of electric vehicles’ lithium-ion batteries is? Can lithium-ion batteries only be charged and discharged 500 times? Most consumers have heard that the life of a lithium-ion battery is 500, 500 times the number of times, the battery will die, many friends in order to be able to extend the battery life, the battery is completely exhausted every time it is charged, so there is time for the battery life Does it affect? u200bu200bThe answer is no. The lifespan of a lithium-ion battery is 500 times, not the number of recharges, but a cycle of charging and discharging. The charging cycle refers to the battery from full to empty, and then from empty to full, which is different from charging. For example, a lithium-ion battery uses half of its power on the first day and then charges slowly. If this is the case the next day, half of the fee will be charged and the price will be reduced twice. This is a cycle, not two. Therefore, it may take several recharges to complete a cycle. After each charge, the capacity of the battery will drop a bit. However, this is a small amount of power. A high-quality battery can still maintain 80% of its original capacity after multiple charges. Many lithium-ion products will continue to be used after two to three years. Of course, the life of the lithium-ion battery needs to be replaced. The so-called 500 recharges means that the manufacturer can achieve approximately 625 recharges at a constant depth of discharge, up to 500 recharging cycles. Due to various effects of real life, 500 charging cycles, especially the depth of discharge during charging is not constant, can only be used as a reference for battery life. With the announcement of the timetable for prohibiting the sale of fuel-powered vehicles in countries around the world, the new energy industry once again ushered in a wave of development. It is foreseeable that lithium-ion batteries will be widely used in the electric vehicle industry in the future. Lithium-ion batteries for electric vehicles are mainly divided into three categories. The first is ternary lithium, which is also the most widely used lithium-ion battery, the second is lithium iron phosphate, and the third is lithium titanate. The penetration rate of lithium titanate Very low, very few users. First of all, ternary lithium-ion batteries are mainly produced by Tianneng and major manufacturers. Among them, the ternary lithium-ion battery used by Tianneng is 18650 lithium-ion battery. The ternary lithium-ion battery is mainly soft-packed ternary lithium, which belongs to the ternary lithium type, and is fully charged at 3.7v and 4.2v. Three taboos for lithium-ion batteries! The first temperature, lithium-ion batteries are afraid of high temperatures. The second largest current, such as 18650 battery is 3c discharge, electric car is 8000w, the battery you use is lower than your discharge current, it will cause the lithium-ion battery temperature to be too high, too high current, short service life, and still In the event of waste, if your power is very large and very fast, it is recommended to choose a 10c current 18650 battery, so it is obviously very important to choose the right battery! The third is the fully charged storage, the ternary lithium battery power is 4.35V , The full protection board is currently charging 4.2V on the market, so many people who buy electric lithium-ion batteries say that there is no more rated capacity. In fact, it is for this reason that generally store electric lithium-ion batteries for a long time, less than 50 The best TVs, for example, if you buy a new mobile phone, many have 50% electricity. If the storage time of the full battery is too long, the capacity of the lithium-ion battery will decrease. In addition to lithium iron phosphate and lithium titanate, these two can be stored for full charge, but you must also pay attention to choosing a better quality protection board.Lithium-ion batteries are the biggest to prevent the end-in the release, three lithium-release will be cancelled, The above fees must also be scrapped. Look at the lithium-ion battery. Ordinary super power, Tianneng Li-ion battery is about 400 cycles, and lead-acid is about 300 times. The relatively stable customized ternary lithium is 500-600 cycles, which is unstable, and it has a lot to do with the assembler's choice of process battery. The customized lithium iron phosphate is about 1000 cycles to fill once a day and use once a day. One cycle, fill in half, and count as half a cycle. Calculate the life of lithium-ion batteries for electric vehicles: Salt baths extend lifespan A research report published yesterday stated that scientists from the Australian Commonwealth Scientific and Industrial Research Organization (CSIRO) have developed a rechargeable lithium-ion battery that is easier to extend. The method of life, the organization calls this battery a salt bath. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
