If a company in the future has completed the subversion of electric vehicles, its innovation is likely to come from the core component - the battery, currently widely used lithium battery, its technology has been stagnant for 10 years. If an electric car can be fully charged in 3 minutes and can take you to hundreds of kilometers, it will certainly rewrite the history of the development of transport. In the electric vehicle industry of the future, new technologies and good services are just one of the conditions for the car companies to be eliminated from the vertical and horizontal markets. The electric balance car is only more intelligent, user-friendly and convenient in technology. After inquiries a large number of foreign materials, combined with the current industry-renowned technology senior personnel, as one of the core of the balance car: lithium battery will show five major trends. Lithium-ion battery prices fell by 2/3 Pure electric cars are expensive. Ordinary American families do not buy Tesla, and BYD 's pure electric car E6 is not affordable to ordinary Chinese families. The important reason for the high price is the high cost of the battery. In the past few years, under the promotion of the national new energy industry policy, there has been a surge of manufacturing lithium batteries throughout the country. Lithium battery packs and pack assembly companies once received over 400 (including lithium batteries for new energy vehicles). Lithium battery companies involved in electric vehicles once had 200-300 companies. However, behind the vigorous new energy manufacturing heat, core materials such as separators for cathode materials, electrolytes, and aluminum-plastic films for flexible packaging batteries are heavily dependent on imports, resulting in high cost of lithium batteries for manufacturing and the same capacity of lithium. The battery, whose price is more than three times that of lead-acid batteries, has led to difficult marketing. In the past three to four years, after the efforts of domestic lithium battery materials companies, the current manufacturing of lithium battery core technology has made a major breakthrough in the use of lithium batteries for electric vehicles, all core materials have basically achieved the localization rate. At present, lithium batteries include 48v11Ah (including 18650 cylindrical steel shells, each battery core is 2200mA, and 65 batteries are connected in parallel), including the charger, and the price is less than 500 yuan, compared with lead-acid batteries. Price advantage. This price is already about 1/3 of the lithium battery has just been introduced to the market. It can be seen that the gradual replacement of lead-acid batteries with lithium batteries is not empty talk. The most expensive lithium battery at present - graphite lithium battery The world’s thinnest and hardest nanomaterials, known as graphene, have extremely low resistivity and extremely fast electron migration. The graphene battery is a new type of battery developed by utilizing the feature that lithium ions move quickly and heavily between the surface of the graphene and the electrodes. The world’s first graphene polymer battery was developed by the Spanish company Graphheno and the University of Corvard. Graphenano is also the first company in the world to produce graphene on an industrial scale. At present, the common three-cell lithium battery has an energy density of 180-200 mAh/g, while the graphene polymer battery has an energy density of more than 600 mAh/g. In other words, if the battery on the Tesla P85 is replaced with a graphene battery of the same weight, its cruising range will reach approximately 1500 km, which is three times the original. In addition to the high energy density, the graphene battery has a much faster charging speed than the lithium battery, and can effectively solve the problem of long charging time. Its life is also very long and can reach 2 times that of lithium batteries. In addition, according to Graphenano, graphene batteries have superior performance, but the cost is not high, but they are 77% lower than lithium batteries. The use of graphene batteries will effectively reduce the cost of electric vehicles and thus increase market competitiveness. Wireless charging technology has a broad market Compared with traditional charging stations and charging piles, wireless charging mainly has the following features: The charging facilities are arranged flexibly. Only the existing parking lot and on-street parking spaces need to be rebuilt to recharge the electric vehicles, and the launcher can even be buried under some roads. By then, the electric vehicles can be driven along these roads while charging, and they will not be occupied. Multi-city space; more user-friendly. No need for plug-in cables to achieve high-speed wireless charging, not only eliminates the need for the traditional parking and wiring of the need for parking and waiting time, and the emergence of the charging lane, but also from static wireless charging to dynamic wireless charging extension, greatly reducing the user The fixed position charging time improves the use of electric vehicles. For example, the receiving boards on both sides of Formula E raceway Formula E can be charged in the moment of an electric racing car; the charging process is relatively safe. Wireless charging is free from sparks and electric shocks. It has no dust and contact loss and can adapt to a variety of harsh environments and weather. It is reported that many companies are now beginning to study electric vehicle wireless charging technology. In January of this year, ZTE and State Grid announced the formation of a joint venture company in Chengdu to provide wireless charging services for electric vehicles. Since then ZTE and Dongfeng Motor have built China's first bus wireless charging demonstration line. Battery Management System (BMS) As the source of energy for the entire balance car, the battery is the focus of safety and security. For electric vehicles, it is not uncommon for batteries to explode and batteries to be natural. As electric vehicle power systems become more complex, BMSs need to perform more functions than ever before. An excellent and intelligent BMS solution can not only prolong the service life of the battery, but also to extend the driving distance when the car adopts the pure electric drive mode. Taking i-ROBOT's battery management system as an example, i-ROBOT's BMS can automatically charge the body and use on-line repair technology to enhance the battery's 24-hour uninterrupted maintenance and truly increase its battery life by more than 50%: ◠The most advanced imported high power (maximum 10C discharge) power cells ◠Battery voltage, current signal monitoring, battery pack temperature detection ◠High-precision SOC estimation ◠Multiple safety protection mechanisms: complete control of short-circuit, over-current, over-voltage, and over-heated charge and discharge. ◠Wide operating temperature range from -10°C to 45°C Modular battery technology stacks batteries like blocks The new Macbook uses modular battery technology. Apple's engineers designed a ladder-like battery cell and stacked several layers of batteries to increase the amount of electricity for Apple products by 35%. Now in the field of balance cars, this technology also has its followers, i-ROBOT (Shanghai New Century Robot Co., Ltd.) has adopted the modular lithium-ion battery system for the latest igo mobility robots. The battery capacity is greatly improved, and the capacity expansion is also facilitated. The modular battery system is composed of flat battery modules composed of battery cells and can be combined into different sizes and performances according to people's needs. Battery modularization, or more precisely, flat panel battery assemblies can have different battery capacities, voltages, and sizes as needed. The number and length of battery cells can be different for each flat panel battery pack. The modularization of battery designs may create a new, interactive battery model that can be used in cars as well as in home life without the need for redesign and build. Perhaps we are witnesses of an era in which energy is once again to be replaced, and the future large-scale battery that provides us with energy is constantly being upgraded from the original, unimpressive battery. The battery is the core component of an electric vehicle and directly determines the most critical cruising range for electric vehicles. With the gradual warming of new energy sources, the investment in the battery industry is also increasing. In the next few years, battery technology will usher in rapid development. Balanced vehicles will also benefit from being the “smart pioneer†of electric vehicles.
