What are the advantages and disadvantages of lithium-ion batteries for electric vehicles

Advantages of lithium-ion batteries for electric vehicles ●Li-ion batteries have long life, light weight and small size. The power function of lithium-ion batteries is similar to that of lead-acid batteries. It can be charged for 6 to 8 hours and can run 30 to 45 kilometers depending on the battery capacity. , The weight is only about 1/5 of the lead-acid battery, the biggest advantage of lithium-ion battery electric bicycles is long life. Disclaimer: The only thing that says that lithium-ion batteries are expensive is to look at the surface. In fact, the cost is about the same as lead-acid batteries. Nowadays, lithium-ion batteries are guaranteed for 2 years, and lead-acid batteries are guaranteed for 1 year. Lithium-ion batteries have activation-free characteristics. It should be noted that when using lithium-ion batteries, the battery will enter a dormant state after being placed for a period of time. At this moment, the capacity is lower than the normal value, and the use time is also shortened. But the lithium ion battery is very simple to activate, it only needs to go through 35 normal charge and discharge cycles to activate the battery and recover the normal capacity. Because of the characteristics of the lithium-ion battery, it is determined that it has almost no memory effect. Therefore, users do not need special methods and equipment during the activation process of new lithium-ion batteries. Lithium-ion batteries have a memory effect. When customers charge lead-acid batteries and nickel batteries, they have always worried about the battery’s memory effect. When lithium-ion batteries are used, we can breathe a sigh of relief. Li-ion batteries do not have a memory effect. Defects of lithium-ion battery electric vehicles ●The price of lithium-ion battery electric vehicles is too high. Now the price of lithium-ion battery electric bicycles is generally several hundred to one thousand yuan higher than that of lead-acid battery electric vehicles, so it is difficult to get customers in the market. Recognition. Lithium-ion batteries are lightweight, environmentally friendly, and will not cause environmental pollution after being discarded. Once the application technology is mature and the market sales increase, the price of lithium-ion battery electric bicycles will come down. The charging time of lithium-ion batteries is too long. It is counterproductive. Li-ion batteries or chargers will automatically stop charging after the battery is overcharged. There is no such thing as a trickle charge that lasts for more than 10 hours as a nickel charger. In other words, if your lithium-ion battery is overcharged, it is also white charged on the charger. In addition, in some electric vehicles, if the charger is not removed after charging for a certain period of time, the system will not only stop charging at this time, but also start a discharge-charge cycle. Perhaps the manufacturer of this approach has its own purpose, but it is obviously unfavorable in terms of battery life. Therefore, after purchasing a lithium-ion battery electric vehicle, you should consult the company or dealer to do a good job of protecting the lithium-ion battery. Lithium-ion battery power needs to be improved. Compared with lead-acid batteries, lithium-ion batteries are much less resistant to shaking in terms of charging and discharging. This is one of the major symptoms of current high-power vehicles that cannot use lithium batteries, which leads to durability. decline. All in all, no one is perfect, no gold is barefoot. Every item is not necessarily safe, everything is relative, but I think: electric car lithium-ion battery manufacturers must take human safety as the core, and then Satisfy the basic needs of customers. The safety of lithium-ion batteries will also be solved in the future. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
