Abstract

An embodiment of the present application provides a method for starting an electronic valve system. The electronic valve system uses a driving unit to drive a motor in the electronic valve system. The method includes: determining the driving capability characteristic value of the driving unit and at least A relationship among the starting demand representation values ​​of the motor; determining a starting mode according to the relationship; starting the at least one motor according to the starting mode. The embodiment of the present application dynamically adjusts the way of driving the motor through the relationship between the driving current and the starting current required by the motor, so as to solve the technical problem of excessive starting current of multiple water valves or excessive starting current of a single water valve.

Description

technical field [0001] The present application relates to the technical field of electronic valve control, in particular, to a method and device for starting an electronic valve system. Background technique [0002] In the thermal management system of new energy vehicles, there are usually multiple electronic valves. The whole vehicle collects the real-time temperature of the drive motor, battery and cockpit, analyzes its heat demand, and adjusts the flow to each position through the electronic valve. Keep the motor, battery and cockpit at the ideal temperature environment for efficient energy use. In the existing thermal management system of new energy vehicles, each electronic valve is an independent entity. If the vehicle wants to change the flow direction of the cooling circuit, it needs to send control commands to each electronic valve separately, requiring each electronic valve to be independent. The control circuit board is used to receive the command signal and driv...
