As people are more and more dependent on energy, and energy determines the wealth of a country, traditional energy sources such as oil and coal are not only limited, but also cause pollution. In the 21st century, green energy has been placed in an important position by most countries in the world. With the development of new energy electric vehicles, charging piles and charging pile test loads have also been born. The editor will explain in detail:

As a necessary equipment for charging new energy electric vehicles, charging piles are equivalent to gas stations and gas dispensers for traditional vehicles. Each charging station is equipped with a charging connector that the user can select and use. So how does the charging process of an electric vehicle work?

 

First, the charging pile tests whether the charging line has voltage and detects the battery status, and then the control board sends commands to charge the battery through the CAN bus, and starts charging output. If the charging circuit does not detect the voltage, the charging pile will report an error and stop working, and the charging pile needs to be restarted to continue to use.

As an electric vehicle charging device, the safety and reliability of the charging pile are very important, so the test load of the charging pile is very important.
