Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle charging, and more specifically, to an electric vehicle charging regulation test bench. Background Art

With the development of the automobile industry, there are more and more control electronics, entertainment multimedia electronics, navigation and on-board communications, etc., which make vehicles more and more complex. The reliability of these electronic components is very important, which directly determines the safety and operational reliability of the entire vehicle. At the same time, the power supply stability of these electronic components is also an indicator to measure their reliability.

[0003] Conducting a test on the charging regulations of electric vehicles is a manifestation of testing the power supply stability of electronic component products. Since the battery pack of an electric vehicle is composed of many batteries connected in series and in parallel, its weight is also very heavy and its volume is also very large. Generally, it is transported with the help of external handling equipment such as cranes and forklifts, and the adjustment accuracy is limited. In addition, the existing test bench structure is fixed, which will cause the problem of inaccurate testing after the electric vehicle battery pack is placed in an irregular position on the test bench; for example, the "battery pack" recorded in a Chinese patent for an electric vehicle battery charging test bench (authorization announcement number CN218767232U) needs to be correctly and standardizedly placed on the "table" before subsequent lifting and adjustment can be carried out; however, it is transported with the help of external handling equipment such as cranes and forklifts, and the adjustment accuracy is limited. In addition, the existing "table" structure is fixed, which will also cause the problem of inaccurate testing after the electric vehicle battery pack is placed in an irregular position on the test bench.

[0004] Therefore, in response to the above problems, an electric vehicle charging regulation test bench is proposed. Utility Model Content
