Analysis of the ten advantages of lithium batteries for electric vehicles

1. Long cycle system life: 1c times the charge and discharge of the lithium power supply, the cycle life is greater than or equal to 1500 times, and the capacity is greater than 70% of the allowable difference copper beam. Even if the lead-acid battery is charged and discharged, the cycle life of the rechargeable battery does not exceed 350 times, and the capacity does not exceed 60%. 2. Low volume charge and discharge performance: Lithium can be used for all normal operations. At -25c, its capacity can reach 70% of its capacity, while lead-acid batteries have a capacity of 50% at -10c and cannot be used for all normal operations at -25c. jobs. 3. Powerful differential polarization maintenance: The capacity of a charged lithium battery is greater than or equal to 80% after two months, while the capacity of a lead-acid battery in two months is only 40% to 50% of the tolerable capacity. 4. Recovery ability: The net weight of the lithium battery pack only accounts for 30% of the lead-acid battery, so the ability to work at the same working voltage, capacity, and life of the lithium battery. 5. High energy density: The capacity of lithium batteries is only 30% of that of lead-acid batteries, so lithium batteries should be stored in the same lithium battery, and its kinetic energy is greater than that of lead-acid batteries. 6. Wide operating temperature range: Lithium can work in the range of -25 to 55 degrees, while lead-acid batteries can only work in the range of 10 to 40 degrees. 7. Short battery charging time: Lithium batteries have the characteristics of charging high-current batteries, the battery charging time is 4-5 hours, and the lead-acid battery charging time is 8-10 hours. 8. Low-carbon environmental protection: Compared with lead-acid batteries that contain a lot of heavy metals that harm the physical and natural environment, lithium batteries are energy-saving products. 9. Capable of charging and amplifying current: Lithium battery charging and amplifying current is 1c times, and the capacity is only 60% of the rated capacity. 10. High current charging and discharging will not damage the service life of the circulatory system: Li-ion charging and discharging and multiple current discharge will not damage the service life of the circulatory system. Lead-acid batteries charge and discharge with multiple currents. Its service life is only 30%-40%. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
