In recent years, our country has paid more and more attention to environmental protection and energy saving. This is what everyone is happy to see. In addition, new energy vehicles have flourished due to the change of national policies. With the advancement of technology, the development of the automotive industry is getting faster and better, and in the face of the strong needs of consumers, major car companies are developing new models. In recent years, in the domestic automobile market, the most popular is new energy vehicles, which is also commonly known as rail trams.

At the beginning, everyone was not optimistic about new energy vehicles, mainly because of battery problems. Everyone knows that the most critical of new energy vehicles is the battery. At the same time, the various secrets of the battery have also become fascinating news.

Regarding the battery pack, of course, everyone is most concerned about the durability and durability of the battery itself. Most people think that the durability of the battery is not strong, and over time, the performance of the battery will slowly decrease. If it is not used properly, the quality of the battery will also be affected. But some people say that batteries can be used for ten years, which is a fact, but why is there such a big difference in the life of the battery?

This is related to the technology, durability, and method of use. Of course, it is also related to the brand, quality, and product characteristics. At present, there are two main types of batteries on the market. One is a lithium iron phosphate battery, one is a triple lithium battery. Both are lithium ion batteries, but there are still some differences between the two. The advantages and disadvantages of lithium iron phosphate batteries and ternary lithium batteries.

advantage:

1. Simple raw materials, safe, cobalt -free and other heavy metals, have high circular utilization value.

2. Good heat resistance. Generally, the spontaneous combustion of the battery occurs at above 800 ° C, so the safety is high.

3. The battery can be used 2000 times, and the working voltage is 3.2-3.4 V, which is available for car owners.

shortcoming:

1. In the low -temperature environment of minus 20 degrees Celsius, the working performance of the battery will decrease and not stable enough.

2. The overall size and weight of the battery are very large, it is not convenient to use, and the production cost is high.
