How is the power battery of new energy vehicles generally composed?

　　In general, the power battery of new energy vehicles is composed of extreme oxidation, negative electrode, electrolyte and diaphragm. However, the material is oxidized at the anode and the reducing agent is recovered at the cathode. If a vapor natural substance (non-gas) is continuously supplied during the anodizing process (that is, the negative stage of the external circuit, also known as the gas electrode), and carbon dioxide (or gas) is continuously supplied on the negative electrode, electrochemical corrosion and current will occur at the anodic level. Unlike basic rechargeable batteries, lithium-ion batteries do not store their raw materials and reducing agents in the rechargeable battery, but in an external tank. When the rechargeable battery is operating (including current and operation), the natural materials and reducing agents of the rechargeable battery must be continuously input and discharged. As such, it is similar in operating mode to a basic automotive petrol or diesel generator. As natural materials and reducing agents continuously enter rechargeable batteries, the natural materials and reducing agents used in power lithium batteries are liquid (gas or liquid). The most common natural materials are pure hydrogen, various hydrogen-containing gases (group gases), and some liquids (such as ethanol solutions). Commonly used reducing agents are oxygen, gases such as purifying room air, and some liquids, such as hydrogen peroxide and sodium cyanide solutions

　　The main purpose of anodizing power lithium batteries is to provide an electrolyte for air oxidation of materials and a general circuit for catalytic reactions. The main purpose of the negative electrode (oxygen level) is to provide a general web page for oxygen and lithium battery electrolytes. Since most of the reactions on the power stage are reflected on the multi-component web page, the power stage is generally porous and coated with a metal catalyst in order to improve the chemical reaction speed

　　The main purpose of the electrolyte is to transport the positive ions present in the electrode reaction to the natural substance level and oxygen level, preventing the transmission of electronic devices between stages. The main uses of the diaphragm are to transfer positive ions, to prevent the immediate transmission of electronic devices at potential, and to separate reducing and oxidizing agents. Therefore, the diaphragm must be a chemical that is resistant to electrolyte solution erosion and insulation, and has good lubricity

　　The lithium-ion battery pack of a pure electric vehicle consists of a number of cells connected in series. A typical lithium-ion battery pack has about 96 rechargeable cells, and for a rechargeable lithium-ion battery pack, the lithium-ion battery pack can now exceed a total operating voltage of 400V. Although the automotive switching power system software uses lithium batteries as a single high-voltage rechargeable battery, the automatic control system must consider the state of each rechargeable battery each time all lithium batteries are charged and discharged. If one battery in a lithium battery pack is slightly smaller than the other, the battery charge will be slowly transferred from the other battery after several battery charging and discharging cycles. If the battery charging is not regularly balanced with other rechargeable batteries, it will eventually go into deep charging and discharging, causing damage and ultimately leading to the failure of the lithium-ion battery. To avoid this important operating voltage monitoring, the operating voltage of each rechargeable battery determines the charging state. In addition, it is important to have a device that enables the charging unit to charge and discharge independently and to balance the charging state of the charging unit

　　The key consideration of lithium battery pack monitoring system is serial communication interface. In the PC board communication, the common choice of serial communication peripheral device (SPI) system bus and I2C bus. The communication cost of each system bus is very low, and the application has little impact on the natural environment. Another option is the control Panel LAN (can) system bus, which is widely used in automotive applications. Cane buses have strong robustness, testing characteristics, and common fault tolerance, but their communication costs are high, as is the cost of raw materials. While it is important to connect the rechargeable battery system software to the vehicle's main tank bus, SPI or I2C communication in lithium batteries is a good choice
