Overview：New energy vehicles have attracted many people's attention since they were listed. In addition to government subsidies, the price of new energy vehicles has become more close to the people. Nowadays, many people will consider the direction of new energy when buying a car, but consumers will inevitably have some questions, such as how the battery life is, and how the quality assurance is regulated. Today we will talk about these new energy issues.
New energy vehicles have attracted many people's attention since they were listed. In addition to government subsidies, the price of new energy vehicles has become more close to the people. Nowadays, many people will consider the direction of new energy when buying a car, but consumers will inevitably have some questions, such as how the battery life is, and how the quality assurance is regulated. Today we will talk about these new energy issues.
First of all, the new energy vehicles are divided into two forms: oil-electric hybrid and pure electric. The working mode and layout of hybrid and electric vehicles are different. Hybrid vehicle is a part of the engine and motor work together, according to different road conditions, the mode used is also different. And pure electric new energy vehicles are driven by motors. The mileage of a vehicle depends on the capacity of the battery pack.
When it comes to the quality assurance of battery packs, the situation should be divided into manufacturers. The quality assurance year and mileage of each manufacturer are different. For example, the new energy industry is more outstanding enterprises, such as BYD, Tesla manufacturers, their battery pack quality assurance is more optimistic. BYD's new energy battery packs are guaranteed for eight years or 150,000 kilometers, while Tesla's is guaranteed for eight years and unlimited kilometers. At the very least, consumers are reassured to see these data, so that they have the desire to buy.
The battery pack of new energy automobile has a life span. According to different materials and different daily use, the life span of the battery pack is also different. For example, iron phosphate batteries, which can be recycled more than 2000 times, have a high charge-discharge ratio and good safety. Normally, bending, high temperature or even puncture will not be a problem. But its disadvantage is low energy density and low storage capacity. Ternary lithium batteries are widely used in new energy vehicles nowadays. Their energy density is relatively high, so their endurance performance will be better and their life will be relatively high. The shortcoming is that their cost will be relatively expensive.
If you want to buy new energy vehicles, you should focus on the manufacturers, after all, battery pack quality and safety are also guaranteed. Normally, when driving new energy vehicles, we should also pay attention to not idling batteries for a long time, and not recharging them until they have been squeezed dry, so that the life of the batteries will be better.
