In addition to improving power battery technology, is there any way to increase the range of new energy
With the continuous development of the new energy vehicle industry, the number of new energy vehicles has also increased year by year. Judging from the latest data released by the Federation of Passengers, my country's new energy vehicle production and sales in September completed 89,000 and 80,000 vehicles, a year-on-year decrease of 33.4% and a month-on-month decrease of 8%. Although the growth rate has eased, it does not hinder the influence of new energy vehicles in the market. In addition to sales, the battery life of electric vehicles has always been a concern for consumers. Especially for pure electric vehicles, mileage anxiety still exists. In addition to improving battery technology, what new ways are there to increase the range? ? What kind of efforts have car companies and power lithium-ion battery manufacturers made for this? Hydrogen Cloud Chain believes that there are only two effective ways to increase the range of electric vehicles, which are the energy density ratio of newly-added power lithium-ion batteries or Lightweight body, in other words, either allow an electric car to carry more electricity, or reduce the weight of the body, so that the energy consumption per 100 kilometers will be greatly reduced. Therefore, in addition to improving the power lithium-ion battery technology, the most effective way to increase the cruising range is the lightweight design of the vehicle. As we all know, as long as the weight of the vehicle body is reduced, the rolling friction on the wheels will be smaller, and the motor will not use more output power to overcome the rolling resistance, thereby effectively extending the driving range. Therefore, whether it is a fuel vehicle or a new energy vehicle, the lightweight design of the body can play an energy-saving purpose. According to the hydrogen cloud chain, many models have already started to use all-aluminum bodies or steel-aluminum composite bodies, and the car body wraps are made of carbon fiber materials to create lightweight bodies. However, the disadvantage of this is that new energy sources are used. The cost of automobiles has increased significantly, making the already high price of pure electric vehicles hit a new high. Therefore, increasing the energy density of power lithium-ion batteries may be the ultimate way to solve the anxiety about the range of new energy vehicles. Of course, methods such as reducing motor power, reducing drag coefficient, using pure electric exclusive platforms, and adopting program-increasing design may increase the cruising range on the side, but to achieve true no cruising range anxiety, solve the power lithium-ion battery technology and charging rate It can be solved completely. In short, power lithium-ion battery technology is not the only way for new energy vehicles to increase endurance. Improvements to many aspects of the car can achieve a certain energy saving effect.
