Utilizing advanced lithium technology to promote the development of electric vehicle market

      With the "thirteen five" plan on the development of electric vehicle industry, the planning and policies continue to implement, the development of electric vehicles market spring is blowing. However, compared with the traditional fuel vehicles, electric vehicle market process is still facing some bottlenecks. "Thirteen five" period, we should rely on advanced technology to crack these bottlenecks. Among them, the power battery is one of the key components of electric vehicles, power battery to play the advantages of advanced technology, will be conducive to the healthy development of electric vehicle industry.

Electric car cost problem
Power battery and system costs in the cost of the vehicle accounted for the highest proportion, therefore, the cost of power battery system is directly related to the cost of electric vehicle vehicles, power battery and system to play the technical advantages, with the vehicle's technological progress, can be achieved The cost of a substantial decline.
Power battery is the unit weight of its ability to store the power to determine the cost of the "second Five-Year" period we achieved 180Wh / kg energy density of industrial goals, "thirteen" during the industrialization of the target is 300 ~ 350Wh / kg, this goal can be achieved through the improvement of materials and technological progress, once achieved this goal, the cost of power batteries can achieve 30% to 50% decline, and through large-scale, standardization and automation manufacturing Aspects of the effort to the "thirteen five" at the end, can achieve the power battery integrated cost more than 50% decline.
       In addition, with the vehicle lightweight and power system efficiency continues to improve, electric passenger cars can achieve an integrated power consumption of less than 10kW per 100 km, combined with the actual use of demand, the future mainstream electric vehicles equipped with 30kWh to 40kWh power battery system can meet The vast majority of user needs (full of electricity, can achieve more than 300 km trip). With such a configuration and cost, the combined cost of electric vehicles will have the ability to compete with the traditional fuel vehicles, and ultimately to achieve the conditions without subsidies to achieve the development of electric vehicle market.
The convenience of the use of electric vehicles
       Compared with the traditional fuel vehicles, the current electric car in the course of the overall feeling is not enough convenience, one is the mileage problem of anxiety, the second is not easy to charge (charging time is long, charging point is not enough). Mileage anxiety is also a large part of the convenience from the charge is not enough, affecting the promotion of electric vehicles. Therefore, how to break through this bottleneck in technology will be a key factor.
       One way is to develop fast-charge technology for power batteries and systems. Most of the current power battery system charging time up to several hours (slow charge), an increase of the use of electric vehicles is not convenient, limiting the scope of electric vehicles driving. The development of power battery fast charging technology, so that power battery and system charging time reduced to 15 minutes or less, will greatly improve the convenience of electric vehicles and the use of efficiency, and advanced power battery and system design, you can achieve this fast charge ability.
      Another way is to focus on the layout, professional fast charging station. Electric car charging a long time, while scattered in different environmental conditions and lack of monitoring the case of long-term charging there is a big security risk. Therefore, combined with the promotion of fast-charge battery system, high-power, centralized professional intelligent charging service station equipment will become a necessity, a reasonable charge station distribution, will greatly enhance the convenience of electric vehicles and enhance the utilization of charging equipment The
       This intelligent charging station can be seen as part of a small intelligent microgrid, including photovoltaic + conventional power grid + energy storage + charging equipment, according to the specific conditions of different regions of the system components to optimize the combination to adapt to specific applications. When such a professional charging site after a reasonable layout, the electric car will be the same as the traditional fuel vehicles easy to use, and the use of cost is much lower than the traditional fuel vehicles.
