Introduction to the advantages of lithium-ion battery packs for electric vehicles

The advantages of lithium-ion battery packs for electric vehicles are as follows: 1. Lithium-ion batteries are light in weight and small in size. The current brands of lithium-ion battery electric vehicles are diversified. In terms of power performance, they are similar to lead-acid batteries. They can be charged for 6 to 8 hours. 30~45 kilometers, the weight is only about 1/5 of the lead-acid battery, and the current general lithium-ion battery is guaranteed for 2 years, and the lead-acid battery is guaranteed for 1 year. 2. The lithium-ion battery pack has the feature of activation-free, the lithium-ion battery is easy to activate, as long as the battery is activated after 3-5 normal charge and discharge cycles, and the normal capacity is restored. Due to the characteristics of the lithium-ion battery itself, 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. 3. Strong continuation ability. Since the weight of the lithium-ion battery pack is only 30% of the lead-acid battery, under the same voltage and capacity, the continuation ability of the lithium-ion battery is strong. 4. The lithium ion battery has a long cycle life. The lithium ion battery is charged and discharged at a rate of 1C, and its cycle life is greater than or equal to 500 times. The electric capacity at the 500th time is greater than 70% of the nominal copper beam. And 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 the capacity is less than or equal to 60%. 5. The operating temperature range is wide. The electric bicycle lithium ion battery can work in the range of -25 degrees to 55 degrees, and its electric capacity can reach 70% of the nominal capacity, while the lead-acid battery can only work in the range of 10 degrees to 40 degrees. , It does not work normally at -25 degrees. 6. The charging time of the lithium-ion battery pack is short, and it is environmentally friendly. Because the lithium-ion battery of electric bicycles can be charged with high current, the charging time is only 4-5 hours, while the lead-acid battery needs 8 to 10 hours. There is no heavy metal lead that is harmful to the environment, and it is a highly environmentally friendly product. 7. The lithium-ion battery pack of electric vehicles can be discharged at a high current: the lithium-ion battery is discharged at a high current at a rate of 1C, and its capacity is only 60% of the rated capacity. 8. Environmental protection: The entire production process is clean and non-toxic, and all raw materials are non-toxic.
