Does 24V lithium-ion battery of electric vehicle need maintenance?

　　1. Household electric vehicles (especially those with high cost performance) usually use ternary lithium-ion batteries. Because of its high energy density and long mileage, it can better meet the current subsidy demand, so many manufacturers choose this battery. However, when ordering, you must fully consider that it is more convenient, but the corresponding durability is also worse. In order to explore the service life of the battery pack, we must first understand what battery it chooses. At present, domestic mainstream pure electric vehicles usually use lithium iron battery, ternary lithium battery and lithium titanate battery. Among the three kinds of batteries, lithium titanate has the longest service life, more than 8 years; Lithium iron ranks second, usually within 5 years; Lithium ternary is the lowest, usually only three years.

　　2. The service life of lithium-ion batteries for 24V electric vehicles is higher than that of lead-acid batteries. The life of lithium battery is longer than that of lead-acid battery. The manufacturer usually guarantees for three years. Due to the development of lithium battery technology, 24V lithium-ion battery electric vehicles began to enter many Chinese families. Compared with traditional lead-acid batteries, lithium-ion batteries have a longer service life. The service life of most lithium ion batteries is designed to be 1000 times, that is, 3-4 years. The lithium-ion battery of electric vehicles has been strictly charged for many times. Usually 1000-1200 times, with a service life of 3-5 years. However, the charging methods of lithium ion batteries and lead-acid batteries are quite different. They must be recharged after depletion. When the battery is not used for a long time, it needs to be fully charged every two months to prevent battery protection and extend battery life.

　　3. The maintenance method of 24V electric vehicle lithium-ion battery is currently in accordance with the international standard, which does not require equipment maintenance. May be used if used in accordance with the manufacturer's requirements. If the lithium-ion battery is not used for a long time, it should be charged every three or five times. Generally, if it is not used for three months, it should be charged once to maintain the activity of the lithium ion battery. If the lithium-ion battery is powered off for a long time, it will accelerate the aging and failure. At the same time, pay special attention to the storage location of the battery. The air should be dry at room temperature.
