Detailed explanation of the advantages and disadvantages of lithium battery electric vehicles

Advantages of lithium battery electric bicycles 1. Long life of lithium battery, light weight and small size. The power function of lithium battery electric bicycles is similar to that of lead-acid batteries (simple electric bicycles). 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 one-fifth of the lead-acid battery, the biggest advantage of lithium battery electric bicycle is long life. Disclaimer: The only thing that says that lithium batteries are expensive is to look at the appearance. In fact, the cost is similar to that of lead-acid batteries. Nowadays, lithium batteries are guaranteed for 2 years, and lead-acid batteries are guaranteed for 1 year. 2. Lithium batteries have activation-free characteristics. It should be noted that when using lithium batteries, the battery enters a dormant state after being left 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 battery is very simple to activate, as long as 35 normal charge and discharge cycles can activate the battery and restore normal capacity. Because of the characteristics of the lithium 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 batteries. 3. No memory effect When charging lead-acid batteries and nickel batteries, customers have always worried about the memory effect of the batteries. When lithium batteries are used, everyone can breathe a sigh of relief. Lithium batteries do not have the memory effect. If there are still customers who don’t know how to charge lithium batteries, they might as well take a look at the following. Disadvantages of lithium battery electric vehicles 1. The high price of lithium battery electric vehicles is due to the fact that the price of lithium 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 obtain on the market Recognition of customers. Lithium batteries are light and environmentally friendly, and there will be no environmental pollution after they are discarded. Once the application technology is sophisticated and the market sales increase, the price of lithium battery electric bicycles will come down. 2. The charging time of the lithium battery is too long. Pulling the seedlings encourages the lithium battery or the charger to automatically stop charging after the battery is overcharged. There is no so-called trickle charge of the nickel battery charger that lasts for more than 10 hours. In other words, if your lithium battery is overcharged, it is also white charged on the charger. And none of us can guarantee that the characteristics of the battery's charging and discharging protection circuit will never change and the quality is fully assured, so your battery will be on the edge of danger for a long time. This is another reason why we are charging against Li Chang. In addition, on some electric vehicles, after charging for a certain period of time, if the charger is not removed, the system will not only stop charging at this time, but also start a discharge-charge cycle. Perhaps the manufacturers of this approach have their own intentions, but it is obviously detrimental to the life of the battery. Therefore, after purchasing a lithium battery electric vehicle, you should consult the company or dealer to do a good job of protecting the lithium battery. 3. The power performance of lithium batteries needs to be improved. Compared with lead-acid batteries, lithium 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. 4. The safety of lithium batteries is outstanding. The safety of lithium batteries still needs to be improved. The danger of fire, incineration and even explosion of lithium batteries still cannot be completely eliminated. A bump in the vehicle may cause the positive and negative materials of the battery to break through the diaphragm, and the energy quickly recharges to the instantaneous ultra-high current when the battery is braked, etc., which will cause the battery to short-circuit, increase the temperature, and cause incineration or even explosion. The cause of the fire is that lithium ions are precipitated due to collisions and short circuits, and fire and incineration may occur when touched with air. In addition, the electrolyte of a lithium battery is an organic electrolyte, and it is easier to burn these substances when they touch the air.
