In the previous article, we shared the power exchange modes of Lifan Automobile, Time and Space Electric (Botan Technology), Beiqi New Energy (Aodong New Energy) and Weilai Automobile. We mentioned that the power exchange mode of Lifan Automobile is mainly based on a larger energy station, which is not a smaller power exchange station. Lifan's centralized energy station is bigger than a gas station. It is a place with many functions. The whole building has three floors, which are used for storing batteries, changing electricity and so on, and each has its own functions.
judging from the design and layout of Lifan's energy station, he didn't intend to make it small and popular at all. Instead, he wanted to make it very large, with this as the core, and spread it around, such as his mobile energy vehicle and distributed power exchange station.
it is impossible for him to spread it on a large scale at this station. Maybe a city has several large centralized energy stations, and then it is enough to distribute some smaller scattered stations. As far as the object of operation is concerned, this user group of Lifan is still his own travel company, hoping to use the car. Lifan's batteries are replaced by boxes. His boxes are very small, and one of his batteries can be moved by hand.
the whole car may need about 8 batteries, and different models, of course, this one is different, so this one has an advantage. That is, my different models can also use different numbers of batteries, and changing the number can meet various models. In other words, this station is suitable for all kinds of cars. Of course, Lifan's operating conditions are not very good, so he is different from other companies in terms of the operating conditions of this power exchange station. Other companies have made various efforts, and Lifan's power exchange station has had some extensive news except when it was first established, and there was basically no news afterwards. Moreover, in fact, since 218, there is not much news about Lifan's power exchange.
then, it's the space-time electric power exchange mode. Space-time electric power exchange started in Hangzhou, and now its main operation place is also in Hangzhou. From the scheme point of view, the scheme of space-time electric power is also to change electricity in boxes, but it is not quite the same as Lifan's. Lifan's box-changing power is very small, so its battery can be stuffed into the engine compartment, under the seat, and these positions. The space-time electric sub-box share is relatively large, and 2~3 batteries are enough for a car. At the beginning, when the battery energy density was low, three batteries were put in one car. Now the energy density has increased. In fact, it is enough to put two batteries in one car.
in terms of the scale of power station change, space-time electric power also adopts a more centralized way, and there is no such trend as building stations quickly and not occupying space. And in fact, in this way, the main method of changing electricity is semi-automatic replacement. With the help of mechanical equipment, manually operate this mechanical equipment, let this mechanical equipment change the electricity for the electric vehicle, and pull out or insert batteries from both sides of the chassis of the vehicle, that is, under the threshold.
of course, it also has some fully automatic power exchange schemes, but in actual operation, it still chooses manual mode, or we call it semi-automatic, which may be related to its automatic operation cost or reliability.
then there is BAIC new energy. If BAIC New Energy, its user base is mainly taxis, and now it has only one car to change, which is the eu quick change version. Although it is still serving taxis, BAIC does have a plan to change electricity for individual users. Of course, judging from BAIC's Optimus Prime Plan, at this stage, it is still dominated by this kind of public travel, and the words of individual users have not been pushed immediately.
Weilai Automobile, Weilai Automobile itself is a mid-to-high-end car company, so it doesn't have a taxi or a network car, which is why Weilai is the only power exchange company for individual users.
In fact, from the four schemes, the "sharing power exchange and battery standardization" proposed by Lifan and Space-Time Electric is very meaningful, because this standardization can make the battery applicable to all kinds of cars of various models, whether it is my car or your car, you can use the same battery.
it is irrefutable that the battery replacement mode of electric vehicles is indeed faster than the charging mode of electric vehicles, and the time for power replenishment is shorter. However, why the battery replacement of electric vehicles has not been popularized and developed for so many years? To a great extent, the reason is that the batteries of electric vehicles cannot be standardized, and the shapes and interfaces of the batteries of each car company are different, and no battery can be replaced on the body of another company.
from the perspective of fuel vehicles, fuel is provided by third-party companies other than car companies and battery factories, such as PetroChina and Sinopec. Their fuel is universal. No matter whether it is a car of BAIC or SAIC, he can go to any gas station to refuel. As for our electricity exchange, Weilai's car can only go to Weilai's power exchange station to exchange electricity, and BAIC's car can only go to BAIC's power exchange station to exchange electricity. In this way, each car company has to build a number of its own power stations in each city, so the combined need for power stations is very large.
of course, we can see from this that it is best for a third-party company to change electricity, not a car company or a battery factory, but an energy service company. This energy service company, like a gas station, is responsible for formulating some oil numbers. The standard of oil is the standard of battery, which is suitable for three types of vehicles. Because it is difficult to unify all models with one battery, it is necessary to specify standard batteries that can specify about three models, and these batteries can adapt to various models. And this company, too, promotes power station change, but his station is universal. As long as any car company does according to his standard, it can replace batteries in this power station. As a result, the popularity of power station change will become much easier, the promotion speed will be faster, and the resistance to power change will be smaller.
