First of all, it is necessary to clarify the premise that charging piles are the basic service facilities that follow electric vehicles on the road.  

Secondly, charging pile is a charging application terminal attached to parking space and power grid.  

With these two backgrounds, we can basically answer your question.  

1. The capacity of charging piles increases with the growth of the number of electric vehicles, the number of parking Spaces and the capacity of the grid. If any of these three aspects are stagnant, the capacity of charging piles will be stagnant, just like the bucket principle, which is always determined by the shortest board.  We all know that the number of parking Spaces and the capacity of the grid are expanding every year, and the growth rate is also very stable. If we consider whether the charging pile will be saturated, we mainly depend on whether the electric vehicle will grow as planned.  

2. The technical threshold for the production of charging piles is not high, and the main difficulty lies in the combination of equipment and operation. The measurement of charging piles should not only look at whether a single device can be charged, even if it is high-speed charging.  Such a technical threshold is very low, most electrical, power manufacturers can do.  Therefore, the charging pile market will not be in short supply. However, if we want to build a charging network with clear planning and clear goals, the equipment and system that can support the network are scarce. Intelligent charging is a good enterprise in this respect, we can pay attention to it.  

3. Regarding the question of profit space, this cannot be answered simply. Charging pile is still oriented to B-end products at present, and B-end products are characterized by customization and non-uniform pricing, which is the biggest difference from C-end consumer goods.  For B end products, different customers will have different prices and profits. This is not the so-called profiteer's meeting people to place dishes, mainly based on the detailed needs of Party A.
