Problems solved by technology

[0005] 1. Traditional test equipment cannot automatically control the output voltage of fast charging, but fix the output voltage test, or adjust the output voltage of fast charging by manually pressing the button
Either the test requirements cannot be met, or the operation is inconvenient and inefficient
2. For traditional resistive loads, when the output voltage of the charger changes, the output current also changes proportionally, and the test requirement is that the output current basically remains unchanged or decreases with the increase of voltage.

Abstract

The invention discloses a quick charger test system and test method and relates to the technical field of an electrical performance test device and method. The test system comprises a man-machine interface, a voltage control panel and an electronic load. The voltage control panel and the electronic load are controlled by the man-machine interface; the voltage control input end of the voltage control panel is connected with the voltage input end of a tested quick charger; and the input end of the electronic load is connected with the current output end of the tested quick charger. The system can automatically set the output voltage of the tested quick charger as needed in the test process, and automatically set the load current of the load connected with the tested quick charger, thereby meeting automatic test of quick chargers in different models.

Description

technical field [0001] The invention relates to the technical field of testing devices and methods for electrical properties, in particular to a fast charger testing system and testing method. Background technique [0002] The charging speed of traditional smart devices such as mobile phone chargers is slow and the charging time is long. This is because the contact current of the USB interface of the charger must be less than 2A. The output voltage of the charger is fixed at 5V, so the maximum output power of the charger is 10W. [0003] Recently, there has been a fast charger whose output USB interface remains unchanged, that is, the maximum output current is still 2A, but its output voltage can be changed, which can be 5V, 12V, 20V, etc., so its maximum output power It can reach 20V*2A=40W, so the charging speed is faster. [0004] The emergence of fast chargers has put forward new requirements for the test equipment of chargers. Charger manufacturers need to pass a lo...
