Problems solved by technology

[0006] However, the simulation of temperature change in the above method is realized by means of discrete points, that is, jumping from temperature point T1 to temperature point T2, which does not conform to the actual temperature change trend, and also misses some temperature boundary values The test cannot achieve the test effect of full temperature coverage

Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] see figure 2 , figure 2 Shows the flow chart of an embodiment of the new energy vehicle thermal management system testing method of the present invention, including:

[0029] S101. Acquire a first temperature threshold and a second temperature threshold of an object to be measured.

[0030] It should be noted that the first temperature threshold and the second temperature threshold of the object to be measured are determined by the characteristics of the components. For example, if the object to be measured is a car battery, then for the cooling function, the first temperature threshold can be the car battery temperature when the vehicle cooling function needs to be turned on, and the second temperature threshold can be the car battery temperature when ...

Abstract

The invention discloses a new energy automobile thermal management system test method. The method comprises the following steps: acquiring a first temperature threshold and a second temperature threshold of a to-be-tested object; partitioning the temperature range of the to-be-measured object according to the first temperature threshold value and the second temperature threshold value; respectively selecting a simulation temperature in each partition; constructing a temperature change curve according to the partition where each simulation temperature is located; and detecting the thermal management function of the whole vehicle under the condition of the temperature change curve. The invention further discloses a new energy automobile thermal management system test platform, computer equipment and a computer readable storage medium. By adopting the device and the method, the continuously changing temperature can be simulated through the temperature change curve, so that the test purpose of full temperature coverage is achieved.

Description

technical field [0001] The invention relates to the field of new energy vehicle software testing, in particular to a new energy vehicle thermal management system testing method, a new energy vehicle thermal management system testing platform, computer equipment, and a computer-readable storage medium. Background technique [0002] Power battery is one of the core components of new energy vehicles, and temperature is an important factor affecting the performance of power battery. If the temperature is too high or too low, the capacity of the power battery will not be fully utilized. In order to maximize the capacity of the power battery, most of the new energy vehicles on the market are equipped with thermal management systems to provide power. The battery is cooled and heated. [0003] In the process of research and development of new energy vehicles, it is necessary to develop and test and verify the control software of the vehicle thermal management system. In order to re...
