There are many reasons why electric vehicles are difficult to promote, but the essence is the battery. The circuit board factory has learned that for a car, people require basic transportation functions first, and additional functions second. However, since electric vehicles use batteries as the power core, it will bring about a very embarrassing problem: what should I do if there is no power?

　　The fuel car is out of gas, open the map app, you can easily find a gas station, and it only takes a few minutes to fill up the gas and start again. However, when an electric car is out of power, it is likely to have to travel long distances to find a charging station, and then wait quietly for 30 minutes or more, which is undoubtedly unacceptable to many people. So, the editor of the circuit board wants to ask, can charging be as fast as refueling? It is a pity that this possibility cannot be seen today or even in the future. But the emergence of another way of thinking and means has solved the problem of slow charging, that is - changing the battery.

　　Replacing the battery is actually replacing the battery technology. As the name suggests, it is replacing the power battery for the electric vehicle. Compared with charging with charging piles, it only takes 3-5 minutes to replace an electric vehicle with a brand new, fully charged battery in a professional power exchange station, from inbound to outbound. , the whole journey takes only about 10 minutes, which is completely comparable to the refueling speed of fuel vehicles.

　　In addition, electric vehicles under the battery swap technology no longer have to worry about the problem of power loss due to excessive battery cycles. It can be said that for consumers, battery swapping technology is beneficial and harmless. But will things really go so smoothly? You must know that one of the cores of the battery swap mode is reflected in the "battery specifications". Because the battery of the vehicle is replaced in the power exchange station, it is necessary to require each vehicle to have a battery of a uniform specification, otherwise it will not only be impossible to uninstall and install. Even after installation, there may be a mismatch.

　　In addition, the construction of the swap station is also different from the general charging station, and its cost is much higher! The circuit board factory learned that as early as 2013, Musk showed the public Tesla's unique 93-second swap. electrical technology. But only 2 years later, as proud as Musk, he had to announce that the promotion of battery swapping technology was of little value. One of the important reasons was the cost.

　　The cost here is not only the construction cost of the power station, but also the use cost of the car owner. In America, where charging stations are everywhere, charging is a very affordable and convenient way. However, the cost of replacing the battery requires the owner to pay 60-80 US dollars for a single time. To sum up, the advantages of battery replacement are that it is fast and there is no worry about battery usage, while the disadvantages are that it is expensive and requires unified battery specifications. The advantage of the charging pile is that the price is low and some car owners can install the charging pile by themselves. The disadvantage is that the charging time is slow and it is inconvenient to go out to charge.

　　At present, there are only three domestic car companies that provide battery swap technology, NIO, BAIC New Energy and Lifan. Among them, the three battery replacement application carriers are somewhat different. Among them, Lifan mainly applies it to its rental vehicles; BAIC New Energy can use its taxis and individual car owners; and NIO mainly targets car owners.

　　The three companies and three different application methods just prove the current "immaturity" of battery swapping technology. Since the rental vehicle or taxi is a whole batch of models, the battery specifications are basically the same, and since the ownership of the vehicle is in their own hands, there will be no problem of excessive use cost, which is also the main reason why Lifan and BAIC New Energy dare to make such a decision. reason. As for why Weilai is only for car owners, I believe you can understand a little by looking at the prices of Weilai's models.

　　At present, the application scope of battery swapping technology should focus on operating markets such as rental vehicles, taxis, and buses. The reason why such a situation occurs is not only related to the battery specifications and costs mentioned above, but also related to the rapid replacement of electric vehicles. The new energy vehicle market has not yet matured, or is advancing by leaps and bounds today. The layout form and vehicle product power are changing with each passing day, so it can only be said that it is too early to change the battery today.

　　But in the future, once the battery specifications are integrated and stabilized, the battery replacement technology will have great advantages when the battery specifications are common between different models. So, for the future, swapping batteries is definitely a viable path.
