Data released by the China Electric Vehicle Charging Infrastructure Promotion Alliance shows that as of September 2024, the total number of public charging piles in China has reached 3.329 million, but the growth rate has slowed significantly compared with the same period last year. In some areas, the number and quality of public charging piles still cannot meet the rapidly growing demand for electric vehicles, especially in first-tier cities, where the frequency of use of charging facilities has increased significantly, but the shortage of public charging piles has affected the user experience of new energy vehicles, including the problem of slow charging. This problem directly interferes with consumers' car purchase decisions.

So how can we improve the charging efficiency of charging piles? Let's talk about it and share your experience~

I have collected some information about charging piles for you. Friends who are concerned about charging piles can come and collect it.

Increase the power. The efficiency will be higher if the power is increased.

Hardware upgrades, including key components such as power supplies, transformers, and DC interfaces, improve the efficiency of the internal hardware design of charging piles and reduce energy loss during transmission.
Choosing charging cables with high conductivity and good quality can reduce energy loss during charging and improve charging efficiency.

Increase the area of the heat sink and use an efficient cooling fan or liquid cooling system.

Thanks for sharing~~

Are there some details or small arrangements in the designed circuit that can improve efficiency? After all, hardware upgrades are all about cost.

Increase the power. If you look at the various fast charging and super charging methods nowadays, you will find that the power is constantly increasing.

From a hardware perspective, increasing power is probably the most effective way. For example, the various charging methods mentioned above range from 18W, 24W to 48W for fast charging, and now 80W is coming out. They are all increasing power. The same is true for car charging piles. They are all charging~

The next step is to optimize hardware equipment, improve efficiency and reduce losses. However, I feel that unless there is a very big breakthrough in chips or materials, there won’t be much improvement.

The second is the battery management system. A good system can make effective use of and better charging, so there must be a special, intelligent overall system, and this overall system is the battery management system on the charging pile.

Then there are all kinds of details, such as protection, protection for various environments, regular inspections, etc. Make sure the machine is fault-free and can be used for a long time.

The above is my general idea. I hope that netizens in the charging pile industry can share more with us.

Cost is still a consideration. I don't know if there are any other ways to improve the efficiency of the existing charging piles besides replacing them.

You raised a good question. Indeed, after all, it is impossible to change it at will. It's all about money.
