Abstract

A method for controlling and managing power of a range extended electric vehicle. The method comprises: acquiring a power requirement for car driving; computing, according to the power requirement, a target power of a driving motor (800), and controlling, according to the target power of the driving motor (800), the driving motor (800); acquiring a target battery power and a system power loss, and computing, according to the target battery power, the system power loss, and the target power of the driving motor (800), a target vehicle power; computing, according to the target vehicle power and a power loss of a range extender, a target power of the range extender; correcting, according to a power value of a battery power regulator, the target power of the range extender, to obtain a corrected target power value of the range extender; and controlling, according to the corrected target power value of the range extender, the range extender. Also provided are a device and vehicle for controlling and managing power of a range extended electric vehicle.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a range-extended electric vehicle and an energy management control method and device thereof. Background technique [0002] The range-extender electric vehicle in the related art, when controlling the range extender, its control scheme is relatively simple and rough, but the actual driving situation of the range-extender electric vehicle is more complicated, and there are many factors that will affect the range extender. Therefore, the range-extended electric vehicle in the related art needs to be improved. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to propose an energy management control method for a range-extended electric vehicle, which takes into account various factors affecting the target power of the range ...
