Power battery manufacturers are here to explain to you the classification of electric vehicle batteries and the advantages and disadvantages of various types of batteries.

The battery is one of the major components of electric vehicles. It provides a source of power for electric vehicles. It is also an important landmark technology for the development of electric vehicles. The performance of power batteries is directly related to the range of electric vehicles. Power battery manufacturers will explain to you. The classification of electric vehicle batteries and the advantages and disadvantages of various types of batteries. Various classifications of batteries Batteries can be broadly classified into three categories: chemical batteries, physical batteries and biological batteries. Among them, chemical batteries are the most widely used in electric vehicles. Definition of chemical battery: A chemical battery refers to a device that can convert chemical energy into electrical energy. The main part includes the electrolyte solution and the positive and negative electrodes immersed in the solution. When in use, connect the wire to the two electrodes, that is, there will be current (discharge), thus obtaining electric energy. Classification: Chemical batteries are currently the most widely used batteries in the field of electric vehicles. From a structural point of view, they can be divided into two categories: storage batteries and fuel cells. Current status of batteries: In the process of technological development, lead-acid batteries and lithium manganese batteries have been eliminated. At present, the mainstream batteries on the market are mainly lithium-ion batteries, and there are also a few nickel-hydrogen batteries. Lithium-ion battery has the advantages of high energy density and cycle life times, which has become one of the most commonly used battery types in electric vehicles. Compared with the ternary lithium battery, the lithium iron phosphate battery has a lower battery energy density, resulting in a battery of the same weight, the cruising range is much worse than that of the ternary lithium battery. But its safety is better than lithium-ion batteries. Under the condition of the same quality of ternary lithium battery, the cruising range of ternary lithium battery is longer than that of models using lithium iron phosphate batteries. But the disadvantage of ternary lithium battery is its poor stability. When its temperature is 250-350℃, the internal components begin to decompose. The volume of the battery pack of the Ni-MH battery is much larger than that of the lithium battery. In addition, the capacity of NiMH batteries will decay during the cycle of charging and discharging. Excessive charging or discharging may aggravate the capacity loss of the battery. Fuel cell Fuel cell is considered to be one of the ideal clean energy sources in the future. It is a chemical device that directly converts the chemical energy of the fuel into electrical energy. Summary: With the support and vigorous promotion of policies, my country's new energy industry has developed rapidly in recent years. At present, various industries are also looking for different ways to solve technical problems. Models such as charging, battery replacement, and mobile replenishment to solve mileage anxiety are also being tried. With the improvement of various technologies, the popularity and future of new energy applications are gradually getting closer.
