What is a special lithium-ion battery? The purpose and characteristics of special vehicles. In recent years, with the continuous advancement of science and technology, ordinary lithium-ion batteries can no longer meet people's needs, especially in some special fields, lithium-ion batteries must use special special lithium-ion batteries. At present, with the development of high technology and changes in the international policy and economic situation, the special vehicle equipment on the battlefield is also changing accordingly. In order to better understand and develop special vehicles, we must understand the purpose and characteristics of special vehicles. What is a special lithium-ion battery? Nowadays, the demand for batteries is increasing, and the requirements are getting higher and higher, and the types of batteries are also various. Special low-temperature lithium-ion batteries are a requirement for temperature. It is important for the low temperature environment of minus 40°C. The battery is required to discharge at 0.2C to reach more than 80% of the rated capacity. The main feature is that it has sufficient capacity and can work normally at low temperatures. Special lithium-ion batteries refer to the batteries that seldom need to be customized in the market and are not easy to buy. They are called special batteries. There are the following types: special-shaped volume, special-shaped voltage, special-shaped materials, special purposes (troop radio, radar, ships, aerospace, etc.), such batteries are called special lithium-ion batteries. Compared with civilian lithium-ion batteries, special lithium-ion batteries have the advantages of wider operating temperature range, higher low-temperature discharge rate, faster charging speed and better explosion-proof functions. Under normal circumstances, special lithium-ion batteries can be used in radio communications, unmanned aerial vehicles, radar fronts, airborne, solar energy storage power supplies, base station energy storage power supplies, and model aircraft power supplies for cold zone rescue, disaster relief power supplies, and cold shoes power supplies. The power supply of special lithium-ion batteries can be further subdivided into: shore power supply, security power supply, high-voltage power supply, medical power supply, aerospace power supply, laser power supply, and other special power supplies. Purposes of special vehicles Special vehicles are vehicles that have been modified and equipped with equipment for special and professional purposes. Special vehicles refer to the general term for various special vehicles and vehicle series that are modified or specially designed for the installation of technical equipment and logistics support equipment, as well as the transportation of personnel and materials. According to their purpose, vehicles can be roughly divided into four types: combat vehicles, traction vehicles, transport vehicles and special vehicles. Combat vehicles usually refer to those vehicles that are equipped with and directly participate in battles and activities at the forefront of the battlefield. The towing vehicle is mainly used to tow artillery, radar, command instrument, as well as vehicles, tanks and other specialties and heavyweights. The transportation vehicles are mainly responsible for the transportation of materials and personnel from the front and rear. Special vehicles are vehicles that are modified from off-road vehicles or ordinary cars to complete various military tasks. Special vehicles generally have special signs or special models, which refer to vehicles that are responsible for special services, hang special vehicle number plates, and install and use alarms and marking lamps. Such as ambulances, fire trucks, police cars, engineering rescue vehicles, etc.; refers to various wheeled or crawler-type special purpose for towing, clearing, cleaning, lifting, loading and unloading, lifting, mixing, excavating, bulldozing, road rolling, etc. Vehicles, or vehicles equipped with fixed special instruments and equipment, engaged in professional work monitoring, fire fighting, cleaning, medical treatment, television broadcasting, radar, X-ray inspection and other vehicles. Important characteristics and requirements of special vehicles (1) Emphasize the development of standardization, serialization, and generalization: ①Develop series of models, and each model will be developed according to the demand for loading tonnage, and the generalization of assembly components is relatively high; ②The saddle is highly standardized , Different tractors and semi-trailers can be used in combination for temporary combination and allocation when urgently needed on the battlefield; ③The tractor is developed based on the general off-road vehicle chassis, which reduces the development cost and facilitates the use, management and maintenance of the army. (2) Diversification of carrying objects: Special vehicles must not only carry tanks, but also fully consider the transportation requirements of various heavy equipment such as artillery and construction machinery. At the same time, they must be able to actively load equipment used to rescue battle-damaged equipment and improve semi-trailer vehicles. The utilization rate of the train. (3) The operation is simple, convenient and reliable. The supporting devices, ferry plates and other accessories of special vehicles should maximize the degree of mechanization of operation to reduce the intensity of operation; the deflation control of tires and air bags when passing bridges and culverts requires rapid, reliable, and automatic control. (4) Improve driving performance: Gradually develop in the direction of adopting automatic transmission to further improve driving performance and off-road passing performance. Lithium-ion batteries have the above advantages in special vehicles. Lithium-ion batteries can be charged randomly and quickly, especially in wars and emergencies, showing excellent performance indicators and low maintenance rates. In the upcoming war, there is no need to maintain all the protection and reduce the burden of logistics management. In addition, it has the advantages of high safety performance and wide operating temperature. In the future, special lithium-ion batteries will usher in a broader space for development.
