The on-board energy system is one of the three core technologies of electric vehicles. It is like the engine of a traditional internal-combustion engine, and it is the “heart†of electric vehicles and the only source of power for electric vehicles. It accounts for 1/3 of the total cost of electric vehicles. The technical level of the on-board energy system is directly related to the quality level and safety of electric vehicles. The energy management system (BMS) is an important part of this core technology. As the vehicle power system is a huge battery pack, which is composed of dozens or even hundreds of single cells, the consistency and balance of the battery are crucial. It is related to the life and safety of the battery. The function of the energy management system is to monitor the status of each battery and the battery level, health, and high-voltage leakage detection to ensure the balance of these hundreds of batteries. Its importance is obvious. In recent years, lithium-ion batteries have become the mainstream choice for power batteries because of their superior performance. The investment in lithium-ion batteries at home and abroad is also very large. The characteristics of lithium batteries make the role of the battery management system even more important.
The number of charge and discharge cycles of a conventional lead-acid battery single 2V battery can reach 1,000 times. However, when the single battery is composed of a 36V or 48V battery pack, the overall number of cycles is reduced to about 400 times. If the voltage increases, the overall number of cycles decreases again.
O2Micro's aerobic lead-acid battery technology implants power management chips in traditional lead-acid battery modules. By using power management and equalization, the number of charge/discharge cycles of the battery pack is the same as that of the single cells, which can effectively extend the tradition. The service life of lead-acid batteries is 1-2 times, and their recoverability is greatly improved. According to a conservative estimate, based on the current total of 130 million EVs in China, the application of aerobic lead-acid battery technology will save China about 1.2 megatons of lead. If a lead with a cross-sectional diameter of 5 centimeters is to be produced, It can be a week around the earth; it can save 57 trillion Chinese, equivalent to a population of 350,000 people in Weihai City, a year of household electricity consumption. The advent of this technology will greatly reduce the cost of use of consumers. For dealers and manufacturers, it will also reduce the rate of battery repair and return rate, while reducing the use and emissions of lead, to protect the environment, build a green transport system with Significance.
Pulverizers are machines that pulverize large solid materials to the required size.
According to the size of the crushed material or the crushed material, the mill can be divided into coarse crusher, medium crusher, fine mill and superfine mill. There are four kinds of external forces applied to the solid in the grinding process: pressing, cutting, impact and grinding. Press rolling is mainly used in coarse and medium crushing, suitable for the crushing of hard materials and bulk materials. Shearing is mainly used in fine crushing, suitable for the crushing of ductile materials. Impact is mainly used in medium crushing, fine grinding, ultrafine grinding, suitable for crushing brittle materials. Grinding mainly in fine grinding, ultrafine grinding, suitable for small pieces and fine particles.
The crusher makes use of the high speed relative motion of the movable tooth plate and the fixed tooth plate, so that the crushed object can be crushed by the comprehensive action of tooth impact, friction and the impact between the materials. The crusher is suitable for crushing Chinese herbs, precious medicinal materials, ores and chemical raw materials in small batches in various varieties, alloys, metallurgy, geology, scientific research and other units.
The pulverizer machine has the advantages of simple structure, solid, stable operation and good crushing effect. The pulverized material can be discharged directly from the grinding chamber of the main machine. The particle size can be obtained by replacing the mesh screen with different aperture. The powder collecting chamber adopts the completely closed silencer structure, which can effectively reduce the working noise. In addition the machine is all stainless steel. The inner wall of the casing is machined to achieve smooth surface, which changes the phenomenon of rough inner wall and powder accumulation of the previous models, so that the production of drugs, food, chemical industry and so on is more in line with national standards and meet the requirements of GMP.
