Nowadays, there are more and better ones on the market. Most of them are still lead-acid battery electric vehicles, but many fields are beginning to introduce 18650 lithium ion battery 3.7v electric vehicles. As the name suggests, 18650 lithium ion battery 3.7v electric vehicles use lithium batteries to replace lead-acid batteries. Are lithium batteries for electric vehicles good? Is it really so good as companies, agents and car sales guides say? Advantages and disadvantages of 18650 lithium ion battery 3.7v electric vehicles.

　　1. Advantages of 18650 lithium ion battery 3.7v electric vehicles:

　　1. Lithium batteries have activation-free characteristics

　　In lithium-ion applications, it should be noted that the rechargeable battery goes to sleep after a period of time, and when the volume is smaller than the standard value, the time usage is also reduced. But lithium-ion batteries are easy to talk about. If you go through all normal battery charging cycles of the system 3-5 times, you can recharge by talking. Due to the characteristics of lithium ion, it is essentially memoryless. So the customer's new Li-Ion didn't interact well with the machine during the whole process.

　　2. The long life of lithium batteries is getting lighter and lighter

　　At the current stage, the brands of 18650 lithium ion battery 3.7v electric vehicles are diversified, such as Giant, Kaiqi, Geobi, Elli cars, etc. The driving dynamics characteristics of lithium electric vehicles are similar to those of lead-acid batteries (a simple electric vehicle). The battery charging 6-8 hours, depending on the battery capacity, it can run 30-45 kilometers, and the net weight is only about 1/5 of a lead-acid battery. The biggest advantage of lithium electric vehicles is their long life. Lithium-ion batteries in the world are expensive only on the surface. In fact, the detailed calculation cost is similar to that of lead-acid batteries. At the current stage, it is generally two years for lithium-ion batteries and one year for lead-acid batteries.

　　3. Lithium batteries do not have memory effect

　　Customers who are charging lead-acid batteries and nickel batteries have always been worried about the memory effect of the battery. After using lithium batteries, everyone can breathe a sigh of relief. Lithium batteries have no memory effect.

　　2. Disadvantages of 18650 lithium ion battery 3.7v electric vehicles:

　　1. The 18650 lithium ion battery 3.7v charging time is too long and cannot be compensated.

　　Lithium or rechargeable batteries completely self-deactivate when charged, and nickel batteries will not charge for more than 10 hours. In other words, if your lithium is full, it will also be white when you put it on the charging head. No one can ensure that the charging and maintenance circuitry of the battery will never change its nature and quality, so there is a risk that your battery will remain recharged for a long time. This is another reason why people refuse to charge long batteries.

　　2. The price of 18650 lithium ion battery 3.7v electric vehicles is too high.

　　At present, the price of lithium-ion electric vehicles is several hundred to one thousand yuan higher than that of lead-acid battery vehicles, making it difficult to gain recognition from customers in the market. Electric lights, environmental protection, and waste are less likely to cause air pollution. Once the application technology is perfected and market sales increase, the price of electric vehicles will decrease.

　　In addition, in some battery cars, if the battery is charged for more than a certain period of time, if the charging head is not removed, the system software will not only stop charging the battery, but also start the charge-discharge-battery charging cycle system. Perhaps the producers of this approach have their destination in mind, but apparently they are detrimental to the life of the rechargeable battery. Therefore, after purchasing a 18650 lithium ion battery 3.7v electric vehicle, we should consult the company or agent to perform 18650 lithium ion battery 3.7v maintenance.

　　3. 18650 lithium ion battery 3.7v power needs to be improved

　　Compared with lead-acid batteries, the working capacity of the battery charging layer is subject to excessive fluctuations. This is a major symptom of the inability to effectively use lithium batteries in current high-power vehicles, resulting in reduced durability.
