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.

Introduction to Application Scenarios

EV charging piles are generally composed of BLIIoT Embedded ARM Industrial Edge Computer BL302, power controller, power module, interface module, interface management system and other parts.

With the BLIIoT Embedded ARM Industrial Edge Computer BL302 as the core, build a safe operation system for EV charging piles. BLIIoT Embedded ARM Industrial Edge Computer BL302 can realize the functions of EV charging pile teaching and data networking, remote monitoring, communication, system fault diagnosis, parameter adjustment, safety monitoring, etc., to meet the needs of users in multi-scenario applications, and to facilitate management personnel to monitor anytime and anywhere The charging pile improves the charging efficiency and user experience of the user. The algorithm decoding performance of the electric vehicle charging station is improved by more than 75% on the original basis, and the power consumption is reduced by nearly 2/3.

Functional Requirements

• Charging status monitoring

BLIIoT Embedded ARM Industrial Edge Computer BL302 can collect the operating status data of EV charging piles, collect voltage, current, temperature, etc. through sensors or instruments, and judge the operating status of EV charging piles based on these data, thereby realizing charging status monitoring and unmanned intelligent operation.

These data can realize environmental monitoring and ensure the safe operation of electric vehicle charging piles.

• Security monitoring

BLIIoT Embedded ARM Industrial Edge Computer BL302 applied to EV charging piles can collect the voltage, current, temperature, humidity, air pressure and other parameter data of EV charging piles by installing sensors, and judge the charging operation based on these data. In this way, the safety monitoring of EV charging piles can be realized. In addition, BLIIoT Embedded ARM Industrial Edge Computer BL302 can also collect leakage information of EV charging piles and issue an alarm in time to detect potential safety hazards in the entire area of the charging station and ensure the safety of the entire area of the charging station.

If you feel fire hazards, artificial charging dangerous behaviors, abnormal equipment temperature, etc., immediately start the sound and light system alarm and SMS phone notification to remind the charging user to leave, and immediately feed back to the staff for processing. If no one responds within a certain period of time, the charged equipment will be controlled to shut down the entire charging station to ensure safe operation and maintenance.
