The new energy vehicles of the circuit board factory will face the difficulty of choosing charging and swapping

There are many reasons why electric vehicles are difficult to promote, but the essence of them all lies in the battery. The circuit board factory understands that for a car, people require basic mobility functions first, and additional functions second. However, because electric vehicles use batteries as their power core, it will bring about an embarrassing question: what should I do if the battery is out?

The fuel truck is out of gas. Open the map app and you can easily find a gas station. It only takes a few minutes to fill up and start again. However, when the electric car is out of power, it is very likely that you will need to travel a long distance to find a charging station, and then wait for 30 minutes or even longer. This is undoubtedly unacceptable to many people. So, the editor of the circuit board would like to ask, can charging be as fast as refueling? It is a pity that this possibility will not be seen today or for some time 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.

Battery replacement is actually battery replacement technology, as the name suggests is to replace the power battery in an electric vehicle. Compared with charging using a charging pile, in a professional swap station, it only takes 3-5 minutes to replace an electric car with a brand new, fully charged battery, from entering the station to leaving the station., The whole journey takes only about 10 minutes, which is fully comparable to the refueling speed of a gasoline vehicle.

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 profitable but harmless. But will things really go so smoothly? It must be known that one of the cores of the battery swap mode is reflected in the "battery specifications." Because in the battery swapping station, each vehicle must have a uniform battery specification, otherwise it will not only be impossible to uninstall and install it. Even after installation, there may be a mismatch.

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

The cost here is not only the construction cost of the replacement station, but also the use cost of the car owner. In the United States, where there are charging piles everywhere, charging is a very economical and convenient way. However, the cost of replacing electricity requires a single payment of US$60-80 from the car owner. This is evident in the high cost of replacing electricity. In summary, the advantages of battery replacement are fast speed and no worries about battery use, but the disadvantages are expensive cost and the need to unify battery specifications. The advantages of charging piles are low price and some car owners can install the charging piles by themselves. The disadvantages are that the charging time is slow and it is inconvenient to go out to charge.

At present, there are only three domestic auto companies that provide battery replacement technology, Weilai, BAIC New Energy and Lifan. Among them, the three power exchange application carriers are somewhat different. Among them, Lifan mainly applies it to its leased vehicles; BAIC New Energy can be used by its taxis and individual car owners; and Weilai is mainly for car owners.

Three companies and three different application methods just proved the current "immaturity" of power exchange technology. Since the leased vehicle or taxi is a whole batch of models, the battery specifications are basically the same, and because the vehicle ownership is in their own hands, there will be no problem of excessive use costs. This is also the main reason Lifan and BAIC New Energy dare to make such a decision. reason. As for why Weilai is only geared towards car owners, I believe you can understand a little bit by looking at the price of Weilai's models.

At present, the application scope of battery swapping technology should be concentrated in the operating market such as leased vehicles, taxis, and buses. The reason for this situation is that in addition to the battery specifications and costs mentioned above, it is also related to the extremely rapid replacement of electric vehicles. The new energy vehicle market has not matured, or is advancing by leaps and bounds. The layout and product capabilities of vehicles are changing with each passing day. Therefore, it can only be said that it is too early to exchange electricity.

But in the future, once the battery specifications are integrated and stabilized, when the commonality of battery specifications between different models appears, the battery swap technology will have great advantages. Therefore, as far as the future is concerned, replacing electricity is definitely a feasible way.
