What kind of battery is an electric car battery? What are its advantages? The development of new energy vehicles is getting faster and faster, the market is becoming more and more mature, and the standards of main parts tend to be unified. However, the core components of new energy vehicles have not been unified so far, and all major car companies have inherited their own standards. What is the reason? So, let's have a look.

What shape does the battery of an electric car have? What are the advantages and disadvantages of each?

First of all, let's take a look at the shape of the electric car battery. The mainstream of the market is square and cylindrical. Square batteries are mainly domestic brands of electric vehicles, BYD and Geely, and cylindrical batteries are mainly imported brands of electric vehicles, represented by Tesla.

Next, let's look at the characteristics, advantages and disadvantages of square and cylindrical batteries. The cylindrical battery represented by Tesla has mature technology and high energy density, which can maximize endurance, but it has the disadvantages of large space occupation and loose battery arrangement. The square battery represented by domestic electric vehicles is small in size and compact in structure, which can save the assembly space of electric vehicles. Its disadvantages are poor heat dissipation and shorter battery life than cylindrical batteries.

Finally, let's see what causes the inconsistent shape of the battery. The first is the automobile manufacturing environment. The time of electric vehicle research at home and abroad is different, and the emphasis of each researcher is different. However, in the early stage of development, the country did not further unify the shape of the battery, so it still followed the standards of its own enterprises in the early stage of research. The second is the structure of the battery. Pure electric vehicles are mostly lithium batteries, but lithium batteries are easy to contact with air and spontaneously ignite. Therefore, when packaging battery cells, enterprises will package them in their own way to meet safety standards, so their shapes are different.

Generally speaking, whether the battery forms of electric vehicles are different or the development of electric vehicles is still in the exploratory stage, there are few electric vehicle enterprises with stable profits, so it is difficult to establish standardization at this time, but with the maturity of technology and market, it will tend to be unified in the future.
