Embodiment 1

[0044] A quantitative evaluation method for the adaptability of a charging pile to a hot and humid environment, comprising the following steps:

[0045] (1) A brand-new charging pile, installed in Qionghai City, Hainan Province, my country to conduct tests in a hot and humid environment. The test site is a cement floor, naturally exposed, and the site is well drained. The distance between the surrounding shelter and the charging pile is not less than the height of the shelter itself. 3 times. The charging pile is installed in the test field and powered on. The charging pile is used to charge the new energy vehicle 2 to 3 times a week, and the operation function of the charging pile is checked.

[0046] (2) The weather resistance failure evaluation, module operation evaluation and severe working condition evaluation were carried out on the charging piles during the static natural exposure test, and the weather resistance failure evaluation score, module operation evaluation score ...

Embodiment 2

[0064] A quantitative evaluation method for the adaptability of a charging pile to a hot and humid environment. The difference between this embodiment and Embodiment 1 is that a brand-new charging pile of a different brand is selected, and the other evaluation methods are the same as in Embodiment 1. The statistical results show that during the test period, there was 1 obvious weather resistance failure of the charging pile, 3 slight failures, and 1 functional failure, with a comprehensive score of 74.7 points; there were 4 abnormalities in the operation of the module, one on the 84th day and one on the 169th day 2 times, 1 time on the 321st day, the correction coefficient is 2.0, and the comprehensive score is 80.4 points; there are 6 days of typhoons, 10 days of heavy rain, 6 days of abnormal temperature and humidity, 3 times of abnormal electrical parameters, and a comprehensive score of 74.8 The comprehensive evaluation score of the charging pile's adaptability to the hot a...

Embodiment 3

[0066] A quantitative evaluation method for the adaptability of a charging pile to a hot and humid environment. The difference between this embodiment and Embodiment 1 is that a brand-new charging pile of a different brand is selected, and the correction coefficient is 2.5. Other evaluation methods are implemented in the same manner. example 1. The statistical results show that during the test period, there were 2 obvious failures of the weather resistance of the charging pile, and 6 slight failures, with a comprehensive score of 96.8 points; 5 abnormalities occurred in the operation of the module, respectively on the 43rd day, the 103rd day, the 186th day, and the 256th day Each occurred 1 time, the correction coefficient was 2.5, and the comprehensive score was 55.0 points; there were 8 days of typhoon, 16 days of heavy rain, 6 days of abnormal temperature and humidity, and 4 abnormal electrical parameters in severe working conditions, with a comprehensive score of 66.0 point...

Abstract

The invention provides a humid and hot environment adaptability quantitative evaluation method for a charging pile complete machine. The method comprises the following steps: (1) extracting the charging pile complete machine which is produced in batch, and installing the charging pile complete machine in a natural exposure test field in a humid and hot environment for a static natural exposure test; (2) respectively carrying out weather resistance failure evaluation, module operation evaluation and severe working condition evaluation on the charging pile in the static natural exposure test process; obtaining a weather resistance failure evaluation score, a module operation evaluation score and a severe working condition evaluation score; and calculating a damp and hot environment adaptability comprehensive score of the whole charging pile by combining respective weights of weather resistance failure evaluation, module operation evaluation and severe working condition evaluation, completing damp and hot environment adaptability evaluation of the whole charging pile, and providing basic data for improvement or use of the charging pile according to the comprehensive score. A natural exposure test is utilized, influence factors in the actual application process of the charging pile are considered, and quantitative evaluation of the damp and hot environment adaptability of the wholecharging pile is achieved.

Description

technical field [0001] The invention belongs to the technical field of product quality detection, and relates to a quantitative evaluation method for the adaptability of a charging pile to a humid and hot environment. Background technique [0002] In order to cope with the shortage of global oil resources and urban air pollution, the focus of the development of the automobile industry in various countries in the world has gradually shifted from the traditional automobile industry to the field of new energy vehicles.
