Problems solved by technology

For functional inspection charging piles, there are too many devices, too large volume, cumbersome transportation and other defects. Especially when there is no working power supply on site, the program-controlled load box and other equipment cannot work normally, which greatly reduces the work efficiency.

Abstract

The invention discloses a self-powered self-loaded off-board charger test method, which is used for detecting an off-board charger and comprises the following steps: S1, a charger signal sampling circuit transmits charger data obtained by sampling to a control module through a signal isolation circuit; the control module judges whether the non-vehicle-mounted charger is completely connected with the self-power-taking and self-load non-vehicle-mounted charger testing device or not according to the charger data so as to judge whether charging is ready or not. According to the self-powered self-loaded off-board charger test method disclosed by the invention, a high-capacity lithium battery and a 7.5 KW program-controlled load are built in, and the charging pile auxiliary power supply A+ / A-powered mode is automatically switched after charging, so that the normal work of equipment is ensured, the lithium battery can be charged, the charging pile can be conveniently and functionally inspected, and in various environments, the operation can be completed by one device.

Description

technical field [0001] The invention belongs to the technical field of testing off-vehicle chargers, and in particular relates to a testing method for off-vehicle chargers with self-powered loads. Background technique [0002] At present, the testing equipment for off-board chargers is basically composed of one off-board charger on-site calibrator plus one or more DC flow control load boxes. Simulate the whole charging process of electric vehicle BSM protocol and internal resistance changes, monitor the charging status and calculate the power output, and realize the measurement and verification of DC charging piles. However, multiple devices are required to be used together, and it is more suitable for fixed inspection places such as laboratories. For functional inspection charging piles, there are too many devices, too large volume, cumbersome transportation and other defects. Especially when there is no working power supply on site, the program-controlled load box and oth...
