Application of Embedded ARM Industrial Edge Computer in EV Charging Pile Control System
Foreword
With the popularity of electric vehicles, charging piles play an important role as the infrastructure for charging electric vehicles. However, traditional charging piles have some problems and challenges in terms of energy management and user experience. In order to solve these problems, the concept of electric charging pile came into being, which incorporates advanced technology to provide smarter, more efficient and more convenient charging services. In the process of realizing the EV charging pile, the excellent performance and characteristics of the BLIIoT Embedded ARM Industrial Edge Computer BL302 provide a strong support for it.
Demands and Challenges of EV Charging Piles
The number of charging piles is huge, the installation locations are scattered, the environment is harsh, management is not easy, and the cost of equipment maintenance is often very high.
The EV charging pile industry protocol is not unified and standardized, and the protocols used by various manufacturers of EV charging pile equipment are quite different, which has caused certain difficulties for the management of the monitoring center and is not convenient for data statistics.
Most of the EV charging stations are in the outdoor environment, which has extremely high requirements on the performance of the equipment, and must be above industrial-grade standards.
For the operation and maintenance of traditional charging stations, the charging piles still need to be inspected and inspected by means of manual inspection on the station and on-site investigation, and remote management must be used to save operation and maintenance costs.
