With the increasing global concern for environmental protection and sustainable development, the application of new energy technologies in the construction of smart cities is becoming more and more widespread. Trams, as an important member of the new energy field, and charging piles, as an important part of the tram, play an indispensable role. With the popularity of trams, the construction and layout of charging piles have also become a key issue.

Choosing what solution to apply to the charging pile is crucial, as it not only concerns charging efficiency and user experience, but also directly affects the development of the new energy vehicle industry and the realisation of environmental protection goals. In the choice of charging pile solution, we need to comprehensively consider a number of factors to ensure that the chosen solution is in line with the technology development trend and meets the market demand.

The following are the advantages of choosing a 4G solution for charging piles:

Firstly, 4G technology can provide real-time networking function. By connecting with the charging pile equipment, the 4G network can obtain data such as charging status, power information and equipment operation in real time and transmit these data to the cloud server. This enables charging pile managers or vehicle owners to remotely view and monitor the operation of the charging pile, thereby improving the operational efficiency of the charging pile and discovering and resolving faults in a timely manner.

Second, the 4G solution supports remote management and control. The charging pile intelligent terminal is connected to the cloud platform through 4G network, and managers can monitor and manage the charging pile remotely through mobile phone applications or computers. Such remote management functions include switch control of charging piles, tariff adjustment, status monitoring of charging pile equipment, etc., providing charging pile operators with a more convenient and efficient way of management.

In addition, the 4G solution is equipped with intelligent scheduling and optimisation functions. By linking with traffic management systems, charging posts can be intelligently dispatched based on factors such as vehicle distribution, charging demand and grid load. This not only improves charging efficiency, but also helps to balance energy supply and demand and reduce pressure on the grid.

Remote management of 4G charging posts is achieved through the following steps:

Data collection and transmission: The charging pile collects data such as charging status, power information, and equipment operating conditions in real time through the built-in data collection module. These data are encoded and modulated by the 4G network module, and then transmitted via wireless communication networks (e.g. mobile networks).

Cloud server processing: Data transmitted to the cloud server is received, decoded and processed by the server. Using powerful computing power and storage resources, the cloud server can analyse, store and display this data in real time.

Remote monitoring and management interface: Managers can connect to the cloud server to view the real-time status of the charging pile, power information, charging records, etc. through remote devices such as mobile phone applications, computer software or web interfaces. At the same time, they can also carry out remote control through these interfaces, such as starting or stopping the charging pile, adjusting the charging power, and setting the tariff.

Troubleshooting and Maintenance: The cloud server can also monitor the operation data of the charging pile in real time, and once abnormal data or fault information is found, it can immediately carry out troubleshooting and notify the management personnel through the remote management interface. The management personnel can take corresponding maintenance measures according to the fault information, such as remote reboot, software upgrade or dispatching maintenance personnel.

Overall, by using 4G network technology, the 4G solution charging pile realises the intelligence and networking of charging facilities, improves the efficiency and quality of charging services, and provides strong support for the popularity and development of electric vehicles.
