1. Battery swapping stations: You may think that building battery swapping stations is expensive, how can it make money? Is it just a gimmick to increase sales by swapping batteries? In fact, the reserve batteries of the swapping stations can be used in advance to recharge the batteries during off-peak electricity price times. Although you may feel that the price difference is not much, when the quantity is considered, it is very considerable (collaboration with various manufacturers/interconnection of battery swapping technologies are all aimed at allowing more vehicles to use NIO's swapping stations). This is why NIO is crazily building swapping stations, not just for servicing the batteries of vehicles, but to achieve multiple benefits. It is indeed burning money in the early stages, which is why it cannot make a profit temporarily, all in preparation, this is the right path.
