The advantages of pure electric vehicles are self-evident, with high environmental protection, low noise, economical use, easy maintenance and extremely low use cost. For household charging piles, one kilometer is less than 1 cent. However, safety, cost, battery life and charging facilities still need to be improved.
After all, pure electric vehicles are mainly batteries, and the right side of the battery is prone to aging, and its recovery rate is not very high. According to relevant statistics, the recovery rate of lithium batteries for automobiles is about 40%, but the residual heavy metal ions such as mercury and lithium cannot be recovered, which will pollute the environment to a great extent.
In terms of battery life, hydrogen fuel cell vehicles are similar to traditional fuel vehicles, with a cruising range of about 600 kilometers, which is superior to lithium-ion electric vehicles; In addition, hydrogen fuel cell vehicles also have the advantages of no noise, short charging time, low temperature resistance and low accident severity.
The advantages of hydrogen-powered vehicles are battery life and environmental protection, but the performance and car purchase cost are too high to be effectively promoted.
Hydrogen combustion only produces water, so hydrogen-powered cars are regarded as the best solution by some people. However, there are still some shortcomings in hydrogen-powered vehicles at this stage, which is also the reason why hydrogen-powered vehicles cannot appear in the market at this stage: the cost is too high and the transportation is inconvenient.
Although each has its own advantages and disadvantages, new energy vehicles are developing rapidly. With the maturity of battery technology, there are more and more electric vehicles with long cruising range and fast charging time.
