I think a big reason why many people buy electric vehicles is because it saves money, in general, even if you use public charging piles, the cost of one kilometer can be pressed within 2 cents.
In contrast, if the ordinary fuel vehicle is calculated according to the fuel consumption of 8L/100km and filled with 92# gasoline, the cost of one kilometer is about 6.6 mao, even if it is a more fuel-efficient non-plug-in hybrid, the cost of one kilometer is about 4.6 mao. The ability of electric vehicles to save money is obvious to all.
But electric vehicles also have shortcomings, that is, the speed of replenishment is very slow. Taking the author's own car as an example, the time to charge a battery takes about 50 minutes (from 5% to 90%), which is still in the case of better quality and higher charging power of public charging piles. If you encounter some charging piles with low charging power, the charging time may reach more than 80 minutes.
Is there any way to make the power speed of electric vehicles catch up with fuel vehicles? At this stage, there is only one way, that is, to replace the power.
Taking the Weilai replacement power station as an example, now the Weilai replacement power station has developed to the second generation, and it takes 9-12 minutes for a battery to change the first generation of the power station, and 6-7 minutes for the second generation of the replacement power station. As for the price, according to the price of different places, taking the Weilai Exchange Power Station in Guangzhou Zhongzhou Trading Center as an example, the electricity fee is charged 1.21 yuan / kWh, the service fee is charged 0.61 yuan / kWh, and the total fee is 1.82 yuan per kWh of electricity. The Weilai Substation, located at the Jinlong Station of Sinopec in Guangzhou, has a electricity fee of 0.96 yuan / kWh and a service fee of 0.52 yuan / kWh, a total of 1.48 yuan / kWh.
In addition to Weilai, CATL also announced that it has officially entered the power exchange business and released the EVOGO brand. The replacement power station invested in Xiamen in the past two days has also been officially put into operation. However, after reviewing the relevant information, the author found that the power exchange service in the Ningde era at this stage is not as good as imagined, and it may be more expensive than refueling.
What is the difference between Ningde era power exchange and Weilai?
Compared with Weilai power exchange, ningde era power exchange has a relatively large improvement point, that is, to make the battery "rounded to zero". In order to be able to adapt to vehicles of different sizes, CATL developed the "Chocolate Exchange Block", which adopts the latest CTP technology of CATL Era, with a weight energy density of more than 160Wh/kg and a capacity of 26.5kWh per battery.

The biggest reason for developing small battery blocks is to maximize guaranteed compatibility. "Chocolate power exchange block" can be applied to a variety of types of vehicles from A00 class to B class, C class passenger cars and logistics vehicles, for small size electric vehicles, 2 batteries can be put into each time, and for large vehicles such as logistics trucks, 4 batteries can be put in each time, this design can allow different sizes of models to share the same type of battery.

In addition, the battery "rounded to zero" also has an advantage, that is, there is no need to carry out "battery rent". In Niolai's Baas service, the battery is rented in the form of a whole lease, even if the usual traffic distance is short and does not require such a large battery, it also needs to be rented out of the whole battery.
Thanks to the battery structure of the Ningde era, the leaser can choose the number of batteries to lease, and the daily short-distance commute can only lease 1-2 batteries, the third and fourth battery slots are vacant, and when you need to go long distances, you can choose to lease 4 batteries, which can reduce the cost of leasing to a certain extent.
What is the difference between the Ningde era substation?
As for the replacement power station in the Ningde era, there is also a certain difference from the Weilai replacement power station.
Thanks to the relatively small size of the "chocolate exchange block", the space utilization rate of the Ningde era substation is higher, and in the case of occupying only 3 standard parking spaces, the NINGDE era substation can store 48 batteries, and the battery capacity reaches 1272kWh.
The second generation of Weilai substation in the case of occupying 4 standard parking spaces, can only put in 13 batteries, if all are 75kWh batteries, then the total battery capacity is 975kWh, if all are 100kWH batteries, then the total battery capacity is 1300kWh.
In addition, the battery block is smaller, and the corresponding replacement speed is faster. According to official information, the replacement time of a single block of the Ningde era substation is about 1 minute, and for vehicles with fewer blocks, the power exchange may even be faster than refueling.
But the Ningde era is not friendly to the electric De era
Seeing this, have you been interested in the power exchange business in the Ningde era? But don't worry, what you're going to say next might dampen your enthusiasm.
In the past two days, the power exchange business of the Ningde era was officially launched in Xiamen, and the first four substations that started the service were in Siming District, Huli District and Haicang District of Xiamen. Officials expect that by the end of this year, 30 substations will be completed in Xiamen. But in addition to Xiamen, other cities have not yet been put into use.
In addition, although the "chocolate power exchange block" can be adapted to different sizes of the car, it also requires the car company to adapt the physical or software level of the block's size and interface in advance when building the car. Most car companies are not very interested in this state of "battery being controlled by others", so at this stage, only one car has completed adaptation, and this car is FAW Besturn NAT.
But this car is more for the online car and taxi market, although it is not clearly stated on the official website that this car is not sold to individual users. But this car is currently bought by related travel companies more, and it is not very attractive to ordinary users.
As for the price of the battery, the most preferential monthly rental price of a single battery block is 399 yuan / block, and the official will also make dynamic adjustments according to the different conditions of use of users. As for the service price of the substation, different electricity and service charges will be charged according to different locations. The cost of the power exchange obtained by the author after asking the relevant customer service is about 1.5 yuan per kilowatt hour.
In terms of rental prices, the rental electricity service in the Ningde era is not cheap at this stage. Take Pentium NAT as an example, the monthly battery rent is 798 yuan (put two batteries). Although it seems to be cheaper than Weilai's 75kWh battery, from the calculation of per kWh rent, the rent at this stage of the Ningde era is still more expensive than Weilai.
But for the travel market, the rent of 798 yuan per month is not expensive, after all, such vehicles may run a day of mileage equivalent to the amount of ordinary people in a week. The author here put out the cost calculation of different monthly mileage, and you can see that the higher the mileage traveled each month, the lower the cost. Therefore, for ordinary consumers, if they only drive 1000km per month, the cost will be quite high, more expensive than refueling. But if you can drive 5,000 kilometers per month, the unit cost is relatively low.
summary
To put it simply, at this stage, the power exchange service in the Ningde era can be seen as a replica of the Weilai Baas+ substation. However, Weilai is selling to individual users, while the Cataline Era is only for online ride-hailing and taxis at this stage, and related vehicles are only sold to travel companies. For travel companies, the use of battery rental to buy a vehicle can save a lot of costs, and the cost of renting a battery can also be successfully passed on to the actual rented driver.
However, for individual consumers, or honestly choose not to change the version of the battery, although the choice of battery rental (if you can buy) can reduce the cost of early car purchase, but the cost of the later period is too high, directly buy fuel vehicles The cost is lower.
