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 objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] see figure 2 , figure 2 A flowchart of an embodiment of the testing method for a thermal management system of a new energy vehicle of the present invention is shown, including:

[0029] S101, acquiring a first temperature threshold and a second temperature threshold of the 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, for the cooling function, the first temperature threshold may be the temperature of the car battery when the vehicle cooling function needs to be turned on, and the second temperature threshold may be the car batter...

Abstract

The invention discloses a testing method for a thermal management system of a new energy vehicle, comprising: acquiring a first temperature threshold and a second temperature threshold of an object to be tested; and partitioning the temperature range of the object to be tested according to the first temperature threshold and the second temperature threshold ; Select the simulated temperature in each zone respectively; construct the temperature change curve according to the zone where each simulated temperature is located; detect the thermal management function of the whole vehicle under the condition of the temperature change curve. The invention also discloses a test platform for the heat management system of a new energy vehicle, computer equipment and a computer-readable storage medium. By adopting the invention, the continuously changing temperature can be simulated through the temperature change curve, so as to achieve the test purpose of full temperature coverage.

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 test 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 cannot be fully exerted. In order to make the power battery exert the maximum capacity, at present, most new energy vehicles on the market are equipped with a thermal management system for power supply. The battery is cooled and heated. [0003] In the process of new energy vehicle research and development, it is necessary to develop and test the control software of the vehicle thermal management system. In order to reduce the ...
