　　What are the classifications of new energy vehicle batteries?

　　The classification of batteries is divided into theories and categories. Generally speaking, the energy of rechargeable batteries can be divided into three types: chemical batteries, microbial rechargeable batteries, and physical rechargeable batteries. Among them, chemical batteries are more commonly used in the new energy vehicle industry, such as: nickel metal hydride rechargeable batteries, lithium iron phosphate batteries Battery rechargeable batteries, lithium nickel cobalt manganate rechargeable batteries, lead-acid batteries, lithium cobalt oxide batteries, etc.

　　According to the structure of rechargeable batteries, new energy vehicles can be divided into two types: batteries and solid-state batteries. The battery pack is suitable for pure new energy vehicles and belongs to the secondary battery category, which can be charged repeatedly; the solid-state battery is specially used for solid-state battery new energy vehicles. It is a power generation device that directly converts the mechanical energy of fuel into electromagnetic energy and belongs to the primary battery. scope.

　　Nowadays, most of the battery cars commonly used in our daily life use battery technology, among which lithium iron phosphate batteries, ternary lithium batteries and nickel metal hydride batteries are the main ones. For example, Tesla Model 3, which has been very popular, uses ternary lithium batteries; some BYD models use lithium iron phosphate batteries; Toyota Corolla Twin Engine and Asia Dragon Twin Engine use nickel metal hydride batteries.

　　How long are the battery cycles of new energy vehicles?

　　As we all know, there are many factors that affect battery cycle life, such as product quality, quality management, use environment, personal driving habits and other intrinsic factors. The impact of external factors on battery cycle life cannot be ignored.

　　Lithium iron phosphate battery rechargeable battery

　　Lithium iron phosphate batteries have a long cycle life and can be recycled about 2,000 times. (PS: The cyclic charge and discharge here refers to charging the battery from zero to 100%. If the battery is only half charged, it is equivalent to one and a half service life.)
