As the power source of Electric Car, batteries have always been regarded as an important landmark technology for the development of Electric Car, and are also an important bottleneck restricting the development of Electric Car. The performance of Electric Car is directly related to the length of the vehicle's cruising range.
Broadly speaking, Electric Sedan Car batteries can be divided into three categories: chemical batteries, physical batteries and biological batteries. Among them, chemical batteries and physical batteries have been used in mass-produced Electric Car, while biological batteries are regarded as one of the important development directions of Electric Sedan Car batteries in the future.
Chemical batteries for Electric Car are currently the most widely used battery types in the field of Electric Car, such as nickel-hydrogen batteries, lithium-ion batteries, lithium polymer batteries, fuel cells, etc. All belong to this category.
Lithium batteries are one of the commonly used battery types in Electric Car at present. With their high energy density and long cycle life, they have quickly occupied most of the Electric Sedan Car battery market. Electric Sedan Car fuel cells are not actually batteries, but a large power generation system to be precise. They are recognized by the industry as the energy source of future cars due to their high energy conversion efficiency, pollution-free, long life and stable operation.
