Description

Technical Field

[0001] The utility model relates to the technical field of charging pile testing, and in particular to a functional testing device suitable for a charging pile control circuit. Background Art

[0002] The function of a charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in public buildings, parking lots or charging stations in residential areas. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding operations such as charging method, charging time, and cost data printing. The charging pile display screen can display data such as charging amount, cost, and charging time.

[0003] After searching, it was found that a functional test device suitable for an AC charging pile control circuit is disclosed in Chinese patent publication number CN213482384U. The first buffer spring is used to buffer the test device body, thereby protecting the test device body from collision with the chassis and causing damage. At the same time, the test device body is prevented from shaking significantly and causing inaccurate test results, thereby solving the problem of poor buffering effect of traditional functional test equipment suitable for AC charging pile control circuits.

[0004] However, the above patent has certain deficiencies in actual use. Although it can solve the problem of poor buffering effect of traditional AC charging pile control circuit function test equipment, it is not very convenient to test the function of the charging pile control circuit, that is, during the test process, the test cable cannot be adjusted according to the height and distance of the charging pile. At the same time, the placement height of the test instrument is also subject to certain restrictions, which makes it inconvenient to observe and record the test data.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
