New generation NIO battery swap advantages and layout

Table of Contents

In recent years, the rapid development of the new energy automobile industry has created conditions for the establishment of the battery swap station station. In order to gain the business opportunity in the market, top 10 battery swapping station manufacturers in China have invested in technology development to meet the needs of different scenarios and different populations. In this process, the new generation of NIO battery swap has achieved great development and carried out a new industrial layout.

NIO battery swap road

Although fast charging piles are currently the most recognized mainstream energy replenishment method for electric vehicles, however, in order to make their own electric vehicles more competitive in the market, powerful car companies are researching additional energy replenishment methods in order to attract consumers with a better charging experience.

For example, Volkswagen and Hyundai are working hard on automatic charging robots, BMW and Porsche are paying more attention to wireless inductive charging, but NIO has taken a path that is not very optimistic about the industry – battery swapping.

The reason why NIO battery swap is not favored is mainly because compared with fast charging piles and automatic charging robots, battery swapping services require more complex infrastructure and equipment for initial investment, and providers often need to pay higher prices.

However, surprisingly, since NIO built the first battery swap station in Shenzhen Nanshan Science and Technology Park in May 2018, and then the first second-generation NIO battery swap was put into operation in Beijing in 2021, the battery swapping model has not only been persisted by NIO until now, the NIO battery swap station is also technically more and more advanced, and the scale is getting bigger and bigger.


Third-generation NIO battery swap

In terms of the battery swapping speed that users pay most attention to, the new NIO battery swap station is 20% faster than the second-generation NIO battery swap station, and it takes less than 5 minutes to achieve ev battery swapping. The ability to make battery swapping faster than refueling is firstly because the third-generation NIO battery swap uses three stations to work together.

The three stations are the station for placing the fully charged battery, the station for battery swapping, and the station for placing and removing the battery. The coordinated work of the three stations can effectively shorten the battery swapping time.

At present, through the optimization of this synergy efficiency, the third-generation NIO battery swap has shortened the battery swapping time of a bicycle by a full minute. Secondly, the space structure of the battery swap station battery compartment has been adjusted and optimized. With the same floor space, the third-generation NIO battery swap increases the number of battery positions from 13 to 21, so that the daily service capacity can be increased by 30%, reaching 408 times of replacement frequency.

At the same time, it should also be pointed out that since the new battery swap station uses a more flexible battery swapping mechanism, it can be compatible with various sizes of different wheelbases and wheel outer distances and models with inconsistent battery packs. Therefore, the battery swap station can be better adapted to NIO models on different platforms and future Alpine models.

Again, the third-generation NIO battery swap has increased the battery charging power by 50%, and is compatible with the 800V electrical architecture at the same time. The substantial increase in battery charging power is attributable to the world’s first NIO self-developed HPC bidirectional high-power liquid-cooled power module adopted by the battery swap station.

The maximum efficiency of this module is as high as 98%, and the charging and discharging power reaches 62.5kW. Not only does the entire charging time become faster, but the process is also more energy-saving and environmentally friendly.


Optimization of New generation NIO battery swap station

When it comes to charging and discharging efficiency, NIO also said that it will strive to make another improvement before the end of this year, turning the current one-way charging into two-way charging, so that the grid participation ability of NIO battery swap station will be stronger. After supporting two-way charging, the NIO battery swap station can participate in grid regulation, use the difference in electricity price to obtain income, and provide some help for the battery swap station to reduce operating costs.

If there are conditions in the future, NIO will also make the battery swap station into an integrated station for optical storage, charging and swapping, so as to expand the power capacity of the station again. Of course, the third-generation NIO battery swap not only improves work efficiency, but also brings better security and convenience in terms of user experience.

In order to make it easier for the car to get in and out of the battery swap station, the height of the new battery swapping platform is about 100 mm lower than that of the second-generation NIO battery swap, making it easier to drive up and down.

And during battery swapping, the battery swapping position of the vehicle is moved forward by 400mm, which will make the vision in the car wider and people sitting in the car can better observe the surrounding conditions.

In addition, in terms of hardware, the third-generation NIO battery swap station will be equipped with 2 laser radars and 2 NVIDIA Orin X chips, and the computing power of a single station can reach 508TOPS. For models that support automatic driving assistance, it can realize functions such as calling vehicles and automatic battery swapping, which greatly improves the convenience of battery swapping operations.

At the same time, it improves the safety and success rate of the battery swapping parking process. For models with weak autonomous driving capabilities, the NIO battery swap station will provide interactive guidance to improve parking safety. If the biggest highlight of the first-generation NIO battery swap station is that it provides tram users with a brand-new energy replenishment experience.

The second-generation NIO battery swap brought better battery swapping efficiency and good battery storage space; then the current third-generation NIO battery swap station has enough strength to become a real competitor for DC fast charging. After all, it does not rely on the support of new battery chemical materials. This is the fastest energy replenishment method that can be used by electric vehicles at present, and it is also an effective way to relieve users’ mileage anxiety.


NIO battery swap layout

NIO officially announced on May 15th that the 1,400th battery swap station — Shanghai Metro Putuo store was officially launched today. According to reports, the new station is NIO’s 61st three-generation battery swap station.

According to the data, battery swapping accounts for more than 60% of the vehicle’s power source. The accumulated battery swapping exceeds 22 million times, and the average daily battery swapping is nearly 50,000 times, which means that a battery swapping is completed every 1.9 seconds on average.

As of May 15, NIO has deployed 1,403 battery swap stations in China, including 374 high-speed battery swap stations, 2,580 charging stations, 15,312 charging piles, and 700,000+ third-party charging piles in China.

At the same time, NIO also announced that the Power Journeys-Shunan Shanshui Line will be officially completed on May 12. The line starts from Changsha, passes through Nanyue Hengshan, Chenzhou Dongjiang Lake, and arrives at Chenzhou Suxianling.

The whole journey is about 391km, and there are 6 battery swap stations, 1 super charging station and 1 mu charging station arranged along the way. At present, NIO has accumulatively completed 55 Power Journeys routes, including the three Tibet routes from Sichuan, Qinghai and Yunnan, the Hexi Corridor, the Duku Highway, the Western Sichuan Grand Ring Road, the Hulun Buir Grassland Line, and the Shenzhou North Pole Line.

As of May 15, NIO has deployed 1,403 battery swap stations in China, including 374 high-speed battery swap stations, 2,580 charging stations, 15,312 charging piles, and connected to 700,000+ third-party charging piles in China.
