Analysis of the core role of CAN communication in charging piles

With the popularity of electric vehicles, charging piles, as key facilities for their energy supply, have increasingly higher technical requirements. CAN communication (Controller Area Network) plays a crucial role among the many technical elements of charging piles? This article will analyze in detail the role of CAN communication in charging piles and how it improves the performance and reliability of charging equipment.

1. Overview of CAN communication

CAN communication is a network protocol widely used in automotive electronic control systems. It is known for its high reliability, real-time performance, and simplicity. CAN communication is mainly used for information exchange between various internal control units to ensure the efficiency and safety of the charging process. Twisted pairs are usually used to ensure reliable communication.

Data integration and management

Multiple modules such as the battery management system (BMS), billing system, and monitoring system inside the charging pile need to exchange data in real-time. CAN communication provide an efficient platform that enables these modules to quickly transmit and receive key data, such as battery status, charging current, voltage level, etc., thereby achieving integrated data management.

Troubleshooting and troubleshooting

CAN communication can monitor the working status of charging piles in real-time. Once an abnormality is detected, such as overload, short circuit,

or overheating, it can quickly transmit fault information to the central processing unit.

In this way, the charging pile can take immediate measures, such as cutting off the power supply, to avoid potential safety risks.

Charging process control

During the charging process, the charging pile needs to adjust the charging parameters according to the actual needs of the electric vehicle.

CAN communication allows real-time communication between control units of charging piles,

ensuring precise adjustment of charging parameters, optimizing charging efficiency, and extending battery life.

Remote monitoring and maintenance

Through CAN communication, the charging pile can be connected to the manufacturer’s remote monitoring system and upload working data in real-time.

This allows manufacturers to understand the operating status of charging piles the first time, detect problems in time, and conduct remote diagnosis and maintenance.

CAN communication in charging piles is a key technology to ensure charging equipment’s efficient and stable operation.

It not only improves the performance of charging piles but also enhances user experience and device maintainability.

As the electric vehicle industry continues to develop, CAN communication will be more widely used in charging piles,

and its technology optimization and innovation will continue to promote the advancement of charging infrastructure.
