Embodiment Construction

[0103] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0104] Such as figure 1 As shown, the electric vehicle charging and discharging facility test system of the present invention includes three parts:

[0105] Part A of the test system: Set up a test environment, including samples to be tested, programmable AC power, programmable AC and DC loads and test instruments. The samples to be inspected are off-board chargers or AC charging piles. The input terminal is a programmable AC power supply, the main function is to provide single-phase / three-phase AC power, set the voltage size, frequency, phase difference, etc., mainly used as the input voltage adjustment source in the test environment of off-board chargers and AC charging piles. The output terminal is mainly a programmable AC and DC load. By simulating load characteristics, you can set the load mode, adjust the load value, simulate the charging outpu...

Abstract

The invention discloses an electric automobile charging and discharging facility testing method and system. A sample to be tested is connected into the testing system, a testing instrument driver is converted into an instrument instruction set by an instruction conversion tool, the instrument instruction set can be identified by a testing module, a procedure set of each testing project is edited by the aid of the instrument instruction set and a basic instruction set and tested to detect the sample to be tested, the changing process of attention amount is monitored according to the change of primitive states, testing process data are acquired, and testing results are outputted. A testing instrument and the testing process can be managed and controlled in a centralized manner, resources can be integrally used, the data can be stored in the centralized manner, the testing instrument can be renewed, instrument control procedures are edited, different testing procedure sets can be edited according to testing strategies, and the procedure set is dynamically loaded and executed. The testing method is equally applicable to other testing fields, and accordingly has a certain expansibility and universality.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a method and system for testing charging and discharging facilities of electric vehicles. Background technique [0002] In order to adapt to the large-scale application and industrialization development of electric vehicles, and to meet the needs of charging and discharging technology and standardized construction of charging and discharging facilities, it is necessary to conduct effective network testing of electric vehicle charging and discharging facilities to improve the safety of electric vehicles during use and efficiency. [0003] At present, the standards for testing electric vehicle charging and discharging facilities mainly include NB / T 33008 (including test specifications for off-board chargers and AC charging piles), Q / GDW 590 (conductive charging interface), Q / GDW 591 (non-vehicle charger), Q / GDW 592 (AC charging pile), which define the relevan...
