Abstract

The present invention relates to the field of test simulation, and its embodiment provides a method for simulating a thermal management water pump of an electric vehicle. The method includes: obtaining a signal input to the water pump, and determining that the input signal is normal; according to the working state of the water pump selected by the user, generating a corresponding PWM waveform; outputting the PWM waveform as feedback of the working state of the water pump. At the same time, it also provides the simulation device of the corresponding electric vehicle thermal management water pump, as well as the corresponding equipment. The implementation mode provided by the present invention avoids the problems of high energy consumption and potential safety hazards caused by using a physical heat management water pump for testing, and is convenient for users to select required working modes.

Description

technical field [0001] The invention relates to the field of test simulation, in particular to a simulation method of an electric vehicle heat management water pump, a simulation device of an electric vehicle heat management water pump, a simulation device of an electric vehicle heat management water pump and a corresponding storage medium. Background technique [0002] In order to have better quality assurance of products, related tests of thermal management functions and strategies are essential, and products that fail to pass the tests cannot be counted as products. At present, most of the thermal management functions of new energy vehicles are developed in VCU (Vehicle Controller) and BMS (Battery Management System). When performing mainstream thermal management (liquid cooling) functions, the required hardware generally includes pumps and valves. , The function of the valve is to change the cooling liquid circulation path, and the function of the water pump is to provid...
