How long is the battery life of pure electric vehicles?

The purchase of new energy vehicles is currently a big trend, but many people also have concerns, such as battery life of purely electric vehicles. . So, how many years does the battery life of a pure electric vehicle last?

Currently, the two types of batteries commonly used in pure electric vehicles sold on the market are ternary lithium batteries and lithium iron phosphate batteries. Different types of batteries have different lifespans. The details are as follows:

If a pure electric vehicle uses a ternary lithium battery, the number of charges and discharges can reach thousands of times. Assuming that the pure electric vehicle has a range of 400 kilometers and travels 50 kilometers per day, it will take 6. jbear. After charging once, the number of charging and discharging times in the dark is less than 60 times. If the number of charging and discharging times is thousands of times, the battery life of pure electric vehicles can generally reach about 10 years.

If the pure electric vehicle battery is a lithium iron phosphate battery, the number of charges and discharges can reach 1,500 to 2,000 times. If charged every 3 days, this battery can be used for more than 20 years; in fact, car owners don't need it at all. I'm too worried because car batteries now have a warranty that lasts about 8 years.

However, the battery life of pure electric vehicles is also affected by driving habits. Some people like fast charging, which will damage the battery and affect its lifespan.

The aboveIt brings together all the information presented to you on the battery life of purely electric vehicles.

What is the lithium battery version of an electric vehicle?

Lithium batteries and lead-acid batteries are currently commonly used battery types used for electric bicycles. each has its own advantages and disadvantages. More precisely, which one is better depends on the user's needs.

Advantages of lithium batteries: Lithium batteries have smaller size, lighter weight, higher energy density, longer life, higher performance, higher security and better usability. Lithium batteries can use fewer battery packs, smaller size, lower cost, less maintenance, higher reliability and higher feasibility.

Advantages of batterieslead: 1. Lead-acid batteries are relatively cheap, inexpensive, and much cheaper than lithium batteries. 2. Lead-acid batteries have good thermal stability and can withstand temperature changes and maintain good performance even at high temperatures.

Classification of new energy vehicle batteries

Hello, lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. . The first lithium battery came from the great inventor Edison. Since the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal are subject to very high environmental requirements. Therefore, lithium batteries have not been used for a long time.

Characteristics of lithium batteries

1. They have a rap weight/energy ratio and a higher volume/energy ratio.

2. Tension. The voltage of a single lithium battery is 3.6V, which is equivalent to 3 nickel-cadmium or nickel-metal hydride rechargeable batteries.Series voltage;

3. Low self-discharge and long-term storage, which is the most important advantage of this battery;

4. Lithium batteries do not have the so-called memory effect of nickel-cadmium batteries, so lithium batteries do not need to be discharged before being charged;

5. Long life expectancy. Under normal working conditions, the number of charge/discharge cycles of lithium batteries is much more than 500 times;

6. Lithium batteries can generally be charged with a current of 0.5 to 1 times the capacity, reducing the charging time to 1 to 2 hours

7. They can be used in parallel as desired

<; p>8. Due to the fact that it does not containt no heavy metal elements such as cadmium, lead and mercury, and does not pollute the environment, it is the most advanced green battery in the world; . High cost. Compared to other rechargeable batteries, lithium batteries are more expensive.

The structure of lithium batteries

Lithium batteries generally have two shapes: cylindrical and rectangular.

The interior of the battery adopts a spiral winding structure, and a very thin and highly permeable polyethylene film insulating material is used to separate the positive and negative electrodes. The positive electrode includes a lithium ion collector composed of lithium and cobalt dioxide and a current collector composed of aluminum film. The negative electrode consists of a lithium ion collector made of carbon foil material and a current collector made of copper film. The battery is filled with an electrical solutionorganic rolytic. In addition, a safety valve and PTC element are installed to protect the battery from damage caused by abnormal conditions and output short circuits.

The voltage of a single lithium battery is 3.6V, and the capacity cannot be infinite. Therefore, single lithium batteries are often connected in series or parallel to meet the requirements of different occasions. If you have a problem with your car, ask the auto guru. Professional technicians from 4S stores can solve the problem within 10 minutes.

Classification of new energy vehicle batteries

New energy vehicle batteries can be roughly divided into two categories, one is lithium iron phosphate battery (LFP) and the other is Lithium Cobalt Oxide Battery (NCA, NCM).

1. Lithium iron phosphate (LFP) battery: the material of the batteryThe positive electrode of this battery is made of lithium iron phosphate, which is highly safe and not prone to explosions and environmental pollution. However, its capacity and weight are relatively small and its service life is short. It is only suitable for urban travel, short-distance travel and other scenarios.

2. Lithium cobalt oxide battery (NCA, NCM): The cathode material of this type of battery is usually made of materials such as lithium cobalt oxide or cobalt oxide, which has a capacity/weight high. ratio and long life. However, lithium cobalt oxide batteries have higher costs and greater safety risks than other batteries. The ternary lithium battery supports high-power charging, so it is suitable for long-distance driving and high-speed driving scenarios.

3. Hybrid lithium batteryium iron phosphate (LFP)-lithium cobalt oxide (NCM) battery: This combination battery is suitable for electric vehicles and hybrid vehicles, achieving a balance between safety and cost-effectiveness.

4. Ternary lithium battery: Ternary lithium battery is a new type of lithium ion battery because of its high energy density, high voltage and longevity. It has advantages such as long life and is widely used in electric vehicles, hybrid vehicles and other fields. Ternary lithium batteries use nickel, cobalt and manganese oxides as positive electrode materials, and carbon materials as negative electrode materials.

Whatever the type of battery, it is very important to choose the model and use that suits you.
