Whenever the electric car is mentioned, the anxiety about it has always been there, and a series of problems such as the fight over the charging pile and the extremely unstable endurance performance due to weather problems in the previous Eleven golden week seem to be vividly remembered. Over time, consumer stereotypes tend to associate electric vehicles with all sorts of troubles. Therefore, this is also the reason why electric vehicles are still resisted by many people so far.
In order to solve these anxieties, many car companies usually have the most straightforward solution, that is, to improve the endurance level of vehicles by increasing the battery capacity. They once thought that as long as the mileage was high enough, the anxiety of the so-called trams would be alleviated. Therefore, we can see in these two years that some pure trams with a advertised range of more than 1000km have begun to appear on the market.
But recently, Tesla CEO Musk slammed this practice ( increasing battery capacity ) , and he also tweeted in a tweet to fans that the tram's mileage is too high.
The reason why he thinks so is because he feels that in the absence of a substantial breakthrough in battery technology, high-endurance trams need to carry larger and heavier batteries, so they must be equipped with higher costs and lighter bodies, so as to maintain that the vehicle will not be too heavy, but it also means that the cost of a car will become higher and higher, which will be a vicious circle.
But is this really the case? Xiaobian feels that everything has two sides, and whether the tram mileage is too high is meaningful or not cannot be generalized. But we can also undeniable that for an electric vehicle, its most expensive body part is the power battery (accounting for more than one-third of the price of the car) If you increase the volume, it will indeed increase the cost of the vehicle. At the same time, the heavier body not only affects the body handling, but also affects the safety, so there are indeed many drawbacks to blindly increasing the battery capacity.
But the breakthrough of battery technology is not easy, in order to break the user's mileage anxiety, increasing the battery capacity is the most effective way for car companies at this stage, especially for the north, large-capacity pure electric models can still provide higher travel mileage even if the weather is cold and causes the endurance shrinkage, and high endurance can also bring a longer car cycle, thereby alleviating the charging anxiety of pure tram consumers.
Therefore, whether the tram mileage is too high or not is meaningful at best can only be said to be a subjective problem. However, I believe that the biggest problem hindering the development of electric vehicles at present must be attributed to charging efficiency. Think about it, for most gasoline cars, they are only about 500/600 km of real endurance, but their biggest advantage is still in the few minutes of replenishment time.
So you think, although the current battery has been able to do about half an hour of fast charging, but in the face of gasoline vehicles such a convenient energy replenishment, obviously not enough to see, if the energy efficiency can be reduced by half on the existing basis, to achieve 10 minutes full, and increase investment in the popularization and construction of charging piles, this beautiful picture will be the best use of electric vehicles. At that time, the low cost of electric vehicles is comparable to the convenience of oil vehicles, and many people will also begin to give up fuel vehicles, right?
Write at the end
Therefore, at present, many companies should think most about how to break through the problem of battery charging efficiency. At the same time, the technological breakthrough in this regard is also destined to be a difficult bone to gnaw, and if you want to really get away from the day when you wave goodbye to anxiety, I think there is still a long way to go for major car companies.
