What is the life of the electric car battery?

For a primary battery, the life of the battery is a function of the operating time (depending on the magnitude of the discharge rate) that gives the rated capacity.

For the secondary battery, the life of the battery is divided into two types: the charge and discharge cycle life and the wet shelf life.

The charge and discharge cycle life is an important parameter to measure the performance of secondary batteries. Subject to one charge and discharge, it is called a cycle (or a cycle). Under a certain charge and discharge system, the number of charge and discharge cycles that the battery can withstand before the battery capacity drops to a certain value is called the charge and discharge cycle life of the secondary battery. The longer the charge and discharge cycle life, the better the performance of the battery. In the commonly used secondary batteries, the charge and discharge cycle life of the cadmium nickel battery is 500 to 800 times, the lead acid battery is 200 to 500 times, the lithium ion battery is 600 to 1000 times, and the zinc silver battery is very short, about 100 times.

Wet shelf life is one of the important parameters to measure the performance of secondary batteries. It refers to the time when the battery is charged and discharged after the electrolyte is added until the end of the charge and discharge cycle life (including the time during which the battery is in the discharge state during the charge and discharge cycle). The longer the wet shelf life the better the battery performance is. Among the commonly used batteries, the cadmium nickel battery has a wet shelf life of 2 to 3 years, a lead acid battery of 3 to 5 years, a lithium ion battery of 5 to 8 years, and a zinc and silver battery of the shortest, only about 1 year.

Battery life has "dry storage life" and "wet storage life". These two concepts are only for the size of the battery self-discharge, not the actual life of the battery. The true life of a battery is the length of time it takes for the battery to actually be used.

The life of the battery depends not only on the battery itself, but also because of our maintenance, especially when dealing with new batteries, and we must ensure that the first time is sufficient. The above is the introduction of the electric vehicle battery life related introduction introduced by Xiaobian, I hope everyone likes it.

Do you really know how long an electric car can ride normally?

The average life of an electric vehicle is 3-5 years, and the battery of an electric bicycle is changed once every year from 1.5 to 1.5 years.

Electric vehicles are generally used in lead-acid batteries, which have the advantages of low cost, recyclability, etc., and are used by most electric vehicle manufacturers. Generally, the battery for electric vehicles is guaranteed for one year (in the first 8 months of the year, if there is a quality problem, the battery is replaced, and the battery is replaced within 4 months), so the battery of the electric vehicle is 70% of the battery capacity used every day. The cycle is one year. After one year, it is not that the battery is useless, but the battery capacity is getting smaller and smaller until it is exhausted!

However, if you use it properly, you can always charge it so that the battery is always in a saturated state. When using it, try to drive as much as possible. When you encounter a slope, change it to implement. Try to avoid more brakes and more starts when driving. In other words, if you use the above points, the battery life will increase greatly, which may be two years or more.

I am an electric car repairman.. Give you the exact data.. Electric car battery depends on what brand you use. The average garbage battery life is -1 year. The average brand battery is -1 year half or so. The battery of the big brand is generally 2 years to 2 years and a half, even longer. You can choose the brand of "Super power battery" in the brand. The price is not very high. The quality can be said to be the national battery industry boss. If you don't understand, you can ask me. Remember to give me extra points.
