How long is the life of a lithium battery?

Do you know how to use lithium batteries correctly? Even if the lithium battery of your electric car can be used for 2 to 3 days on a single charge, I suggest you charge it every day. Lithium batteries should be charged as soon as possible in future use, and the batteries should be as full as possible. Regular deep discharge of the battery also helps to activate the battery, slightly increasing its capacity. The next villain will teach us how to extend the life of electric vehicles. First, the advantages of lithium batteries 1. Lithium batteries are light in weight and small in size. Lithium battery electric vehicles are now diversified brands. The power function is almost the same as that of lead-acid batteries. It can be charged for 6 to 8 hours. Depending on the battery capacity, it can run for 30 to 45 kilometers. The weight is only 1/5 of that of lead-acid batteries. Now the general lithium battery is 2 years, and the lead-acid battery is 1 year. 2. The lithium battery is not activated. The activation of the lithium battery is very simple. Only through 3-5 normal charge and discharge cycles can the battery be activated and the normal capacity can be restored. Due to the characteristics of the lithium battery itself, it has almost no recall effect. Therefore, the user is not a special method and equipment in the process of activating the new lithium battery. 3. Lithium batteries have a memory effect. When charging lead-acid batteries and nickel batteries, we always worry about the memory effect of the battery. However, the lithium battery of the electric bicycle has no memory effect, so we can not worry about the power consumption of the battery before charging. 4. The lithium battery has a long cycle life. The charging and discharging rate of lithium batteries is 1C, and the cycle life is greater than or equal to 500 times. The capacitance at the 500th time is greater than 70% of the nominal copper beam. However, even if the lead-acid battery is discharged at 0.5 and charged at 0.15c, its cycle life is less than or equal to 350 times, and its capacitance is less than or equal to 60%. 5. Wide operating temperature range. The lithium battery of an electric bicycle can work at a temperature of -25c to 55c, while a lead-acid battery can only work at a temperature of 10c to 40c, and cannot work at a temperature of -25c. 6. The lithium battery has a short charging time and is environmentally friendly. Since the lithium battery in an electric bicycle can be charged with a high current, the charging time can reach 4 to 5 hours, while the charging time of a lead-acid battery is 8 to 10 hours. There is no heavy metal lead that is harmful to the environment, and it is a highly environmentally friendly product. Second, lithium battery selection button 1. Resolutely do not buy batteries lower than the unified wholesale price of the store. 2.2 Products that have not passed the market inspection for more than two years. 3. There is no electric car manufacturer and will never buy a car with a car battery. 4. High-priced batteries, if they are not processed by large manufacturers, resolutely do not buy them. 5. Resolutely do not purchase batteries that replace the national standard scale. 3. How long will the life of the lithium battery of an electric vehicle last? I believe that most customers have heard that the life of a lithium battery is 500 times, 500 times of charging and discharging, beyond this number, the battery is dead, many friends in order to be able to extend the battery life, Does the battery life really have an extended effect every time before the rechargeable battery is completely exhausted? The answer is no. The life of a lithium battery is 500, which does not refer to the number of times of charging, but a cycle of charging and discharging. A charging cycle means that all batteries go from full to empty, and then from empty to full. This is not the same as charging. For example, a lithium battery uses half of its power on the first day and then charges slowly. If the next day is the same, use half of the battery to charge twice, which can only be counted as one charging cycle, not twice. Therefore, it may take several recharges to complete a cycle. Each charge cycle reduces the battery capacity 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 can still operate normally after two to three years. Of course, the lithium battery still needs to be replaced after it reaches the end of its life. The so-called 500 times means that the manufacturer completes about 625 rechargeable times at a stable depth of discharge, and can reach up to 500 recharge cycles. 500 charging cycles can only be called battery life, because of various effects in real life, especially the unstable depth of discharge during charging.
