Abstract

The invention relates to the field of test simulation, and provides a simulation method of an electric vehicle thermal management water pump. The method comprises the following steps of acquiring a signal input into the water pump, and determining that the input signal is normal; generating a corresponding PWM waveform according to the working state of the water pump selected by a user; and outputting the PWM waveform as working state feedback of the water pump. Meanwhile, the invention further provides a corresponding simulation device and corresponding equipment of the electric vehicle thermal management water pump. According to the method, the problems of high energy consumption and potential safety hazards caused by the adoption of an entity thermal management water pump for testing are avoided, and a user can conveniently select a required working mode.

Description

technical field [0001] The invention relates to the field of test simulation, and in particular to a simulation method for an electric vehicle heat management water pump, a simulation device for an electric vehicle heat management water pump, a simulation device for an electric vehicle heat management water pump, and a corresponding storage medium. Background technique [0002] In order to ensure better product quality, tests related to thermal management functions and strategies are essential, and products that fail the tests cannot be counted as products. At present, most of the thermal management functions of new energy vehicles are developed in the 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 role of the valve is to change the coolant circulation path, and the role of the water pump is to provide power for the coolant...
