Since the development of pure electric vehicles, they have been plagued by "endurance anxiety", and it is precisely because of this problem that many consumers have turned to buy oil cars, hybrid and extended range vehicles. There is no doubt that pure electric vehicles have also lost a part of the market because of this, although most mainstream pure electric vehicle companies on the market have made great improvements in terms of actual mileage, but they still have not been able to fundamentally solve the problem.
It is no exaggeration to say that the fuel vehicles, hybrids, range extenders, etc. that many consumers are now pursuing are only a matter of time before they are eliminated, and if nothing else, their "double carbon target" is an insurmountable gap. Coupled with the current trend of the automobile market is becoming clearer, it can be seen that the general direction is leaning in the direction of pure electric vehicles, and in order to solve the "endurance anxiety" of pure electric vehicles, major car companies and battery manufacturers are also doing their best.
At present, the two most reliable ways to alleviate "endurance anxiety" are "fast charging" and "fast power exchange".
In terms of fast charging, many car companies have set an example in it, among which GAC Aean has developed an ultra-double speed battery technology after seven years, which can reach 200km endurance after only 5 minutes of charging. On the surface, it is a "partial" solution to the problem of endurance anxiety, but in fact, there are many problems that are extended.
First of all, if you only charge for 5 minutes many times, does it have an impact on the life of the battery?
Second, the battery itself has the risk of false standards, full of 200km, the actual endurance can reach 200km?
Based on these problems, some brands label ultra-fast charging technology, in fact, is only a vain name.
Another - quick power change!
This model seems to be relatively reliable, but there are still many problems.
Let's start with the pros. One of the fast power exchange than fast charging more time-saving, not long ago Ningde era launched the "chocolate change block", one minute can replace a block, it can provide 3 blocks at the same time, each block has almost 200km endurance, even if you change 3 blocks at a time, it only takes 3 minutes, but the mileage can reach nearly 600km.
Second, fast power exchange is more able to save land resources than fast charging.
Fast charging involves charging piles, each private car charging pile occupies an area of about 12 square meters, 10 private car charging piles occupy an area of 120 square meters, relatively speaking, this is indeed a bit of a waste of "resources". The substation is centrally managed, which reduces the area occupied by the land.
But then again, there are many disadvantages to quickly changing the power.
First, the cost is high. To build a replacement power station, it costs millions to say the least, and its return on investment cycle is relatively long, reaching 5 or 6 years. At the same time, this is also the reason why the replacement power station developed after the development of fast charging piles, because the investment was too large, and no one was willing to take this risk in the case of market instability at that time.
Second, there is no uniformity. At present, the mainstream pure electric car brands have not been standardized and unified in the battery, because they are doped with their own "housekeeping skills", who are not willing to unify the standards, after all, there are still interests involved during this period, but it is precisely because of the differentiation that these car companies continue to make progress, so this is a disadvantage for consumers, but it is an advantage for major car manufacturers.
Write at the end
In the long run, fast charging and fast power exchange will not become a competitive relationship, but they will become a harmonious complementary relationship, because for the market, they have their own advantages, the market can also accommodate them, then I think based on this, in everyone's mind, whether there is a future for power exchange, there should already be a standard answer, right?
