Electric car air conditioner temperature drop test method and system

Abstract

The present invention discloses an electric car air conditioner temperature drop test method and system. The method comprises the following steps of: turning on a cooling mode of an air conditioner, starting timing to obtain first timing time, and controlling an electric car to be tested to perform acceleration at a preset accelerated speed; when the current speed is equal to a first preset vehicle speed, stopping acceleration operation of the electric car, and controlling the electric car to be tested to run at a constant speed at the first preset vehicle speed; when the first timing time isequal to a first preset time threshold value, obtaining an acceleration temperature value; performing timing again to obtain second timing time, and controlling the electric car to be tested to perform idling operation; when the second timing time is equal to a second preset time threshold value, obtaining an idling temperature value; and determining whether the acceleration temperature value andthe idling temperature value are in corresponding preset temperature ranges or not, if yes, determining that the air conditioner cooling test of the electric car to be tested is qualified. The electric car air conditioner temperature drop test method and system are high in test accuracy and avoid wrong test results caused by human somatosensory test.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method and system for testing the cooling of an electric vehicle air conditioner. Background technique [0002] With the development of the economy and the advancement of technology, the number of cars owned by urban residents is increasing rapidly, and road traffic accidents have become one of the important threats to human life safety. Therefore, how to improve the overall safety performance of automobiles has become the most important research direction for automobile engineers. [0003] With the rapid development of new energy technology, the use of electric vehicles is becoming more and more frequent. Electric vehicles (BEV) refer to vehicles powered by vehicle-mounted power supplies, driven by motors, and meeting the requirements of road traffic and safety regulations. Electric vehicles Automobiles have attracted more and more attention due to their advantages ...

Problems solved by technology

[0004] However, in the existing electric vehicle air conditioner cooling test process, artificial somatosensory testing is used to determine the test results of the electric vehicle air conditioner cooling test, which makes the test accuracy low, which in turn leads to inaccurate test results for the electric vehicle air conditioner cooling test
