1. Long cycle system life: 1c times the charge and discharge of lithium power supply, 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 capacity, while lead-acid batteries have a capacity of 50% at -10c, and cannot be used for all normal operations at -25c the work.
3. Powerful differential polarization maintenance: The capacity of a charged lithium-ion battery is greater than or equal to 80% after two months, while the capacity of a lead-acid battery within 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 lithium battery life.
5. High energy density: The capacity of lithium-ion batteries is only 30% of that of lead-acid batteries, so lithium-ion batteries should be stored in the same lithium-ion batteries, which have greater kinetic energy than 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 large 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-ion 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 multi-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%.
60V40ah electric vehicle lithium battery maintenance knowledge
At present, lithium-ion batteries have been recognized and applied by more and more users. In order to enable users to master the knowledge of lithium-ion batteries, the manufacturer of Lithium-ion batteries has sorted out some basic knowledge of lithium-ion batteries for reference. And training.
1. The newly purchased lithium-ion battery also has less power, but because the new rechargeable battery has a part of the storage battery, it does not meet the proposed application when the charging head displays the information signal light when charging. This is a special reminder: there is no need to be credulous about the 12-hour discussion about the initial use of lithium-ion on the Internet.
2. Lithium has no memory and can be used at any time, but it must be noted that lithium cannot be overcharged and discharged. Overcharge and discharge will cause a lot of volume damage. When the battery car prompts low power consumption, you need to start charging immediately.
3. Under normal circumstances, the newly filled lithium-ion battery will be idle for half an hour, waiting for the battery performance to be stable, otherwise, it will damage the battery performance.
4. If you are not using the battery car for a long time if you try to charge the lithium, remove the lithium in the battery and charge to 80% every two months, and there is no need to mix the rechargeable battery with metal materials Together, to prevent metal material objects from hitting the positive and negative electrodes of the battery, causing short-circuit failure, damaging the rechargeable battery, and even causing risks.
5. Note that lithium-ion batteries are charged at 0c to 40c in natural environments, and lithium-ion batteries are charged at -20c to 40c.
6. Do not knock, acupuncture, step on, modify, or expose the battery, do not place the battery in a microwave or high voltage environment, use a regular matching lithium battery charger to charge the battery, do not use inferior chargers.
