Description

Technical Field

[0001] This application relates to the field of charging pile testing, and in particular to a charging pile testing device based on plug-and-charge functionality. Background Technology

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. With the rapid development of electric vehicle charging infrastructure, the number and frequency of use of charging piles are constantly increasing, making the stability and safety of charging piles a key concern for both users and operators.

[0003] The input end of the charging station is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging stations generally provide two charging methods: regular charging and fast charging. Users can use a specific charging card to swipe on the human-machine interface provided by the charging station to perform corresponding charging operations and print out fee data. The charging station display screen can display data such as charging amount, cost, and charging time.

[0004] However, the current traditional card-swipe charging pile detection process has some limitations. First, the manual card-swipe process is cumbersome and prone to errors, greatly affecting detection efficiency and accuracy, while also increasing labor costs and workload. Second, different charging pile operators use different RFID card systems, lacking a unified standard, resulting in users needing multiple cards, which is inconvenient. Furthermore, using a mobile app to scan a code to start charging is also somewhat cumbersome and limited, and is greatly affected by external signals and lighting conditions. Utility Model Content
