In the future, the investment and construction trend of new energy charging piles will be community-based and public-assisted. The problem of community charging is an unavoidable problem for charging operators to solve. By using EMQX empower charging piles, the problems of heterogeneous access of equipment, difficult control of regional decentralization, and bad deployment environment are solved, making EV power differentiated in parallel with the market, and injecting vitality into the construction of Intelligent Community charging pile.

——Chen Liangyuan (Senior solution expert of destination charging industry of Shanghai EV Power Co., Ltd.)


The latest report released by EVCIPA (China Electric Vehicle Charging Infrastructure Promotion Alliance) shows that EV Power Co., Ltd (hereinafter referred to as EV Power) has the largest number of community charging stations in China, and is the earliest and largest existing independent destination charging operator in China. Different from other charging pile companies in the market, EV Power focuses on charging from destinations represented by community scenarios for business arrangement, paying attention to the user groups of private passenger cars, and using the car's free time to charge them, so as to avoid users deliberately looking for public charging piles .


Community charging becomes an general trend

If electric vehicles are to truly enter thousands of households and be accepted by the market, the charging needs of end users must be focused. From the perspective of user charging scenarios, it is not realistic to rely entirely on public charging piles. The problem of community charging is also being paid more and more attention by charging operators. Both NIO and State Grid announced that they will invest heavily in community charging and destination charging markets. In the future, the investment and construction trend of new energy charging piles will be community-based and public-assisted. The problem of community charging is an unavoidable problem for charging operators to solve.

The equipment is dispersed and different, the construction environment is complex

The lack of fixed parking spaces and the inability to install charging piles have become a challenge for destination charging and the construction and maintenance of community charging piles. At the same time, in addition to factors such as low property coordination and difficulty in grid connection, there are also objective problems such as equipment differentiation, extremely scattered distribution areas, bad construction environment, poor signal and difficulty for maintenance.

The business application is complicated and interweaved

For multi-scenario operations, multiple configurations of the back-end application layer are interleaved. If there is no unified data management channel, frequent scheduling and distribution of massive data in the application will easily cause the decline of the overall system stability, and decouple equipment and applications. Focusing on application development is an urgent problem to be solved in IOT.


EV Power began to apply the concept of edge computing and IOT multi connection to the construction and operation of new energy charging pile in 2016, and chose EMQX developed based on Erlang/OTP to be deployed in a private cloud environment, combined with the self-developed VPN charging network to form Unique cloud-edge integrated charging pile operation network platform.

Self-developed edge to overcome weak/disconnected network

On the device side, EV Power has realized the application in weak/disconnected network environments, as well as unattended and remote operation and maintenance through self-developed edge gateways and BLE field computing solutions.

Efficient distribution of multi-application data by rule engine

At the access layer and platform side, the TimescaleDB data persistence plugin provided by EMQX Enterprise performs time series data storage and analysis. The message queue bridging plugin feeds the data to its own micro service operation system, which helps the platform extend to refined and big data AI applications, and accelerates the implementation of community charging applications.



The development and construction of EV Power quick-charging piles is more flexible, which enhances the operation ability in multiple scenarios and gradually improves its surrounding network effects. It has achieved the highest theoretical concurrent data storage of 30,000 pieces per second and a total of up to 30 million pieces per day, including networking status, charging real-time log, site power situation, user usage records, etc., and the billing is analyzed in real time. EMQX also shows a high degree of stability and cost-effectiveness. Within the same hardware facilities and price range, EMQX has rare rivals with the service capabilities it provide, which can save a lot of infrastructure costs for the company.

In the future, by using the characteristics of charging pile data entry, the powerful data access, and the processing capabilities of EMQX, we will build a cloud platform that connects the charging network, the Internet of vehicles, and the Internet. It will provide efficient solutions in the IoT era for customers facing charging problems, and improves the use efficiency of charging piles to truly meet the requirements that every kilowatt-hour of electricity can be checked and every complaint can be followed.
