Method and device for intelligently adjusting amount of generated electric energy

Abstract

The invention discloses a method and device for intelligently adjusting the amount of generated electric energy. The method includes the following steps that: the terminal voltage of a generator is obtained in real time; if the terminal voltage of the generator is smaller than a first preset voltage threshold value, the generator is control to increase the amount of generated electric energy, wherein the first preset voltage threshold value is smaller than rated output voltage of the generator; and if the terminal voltage of the generator is larger than a second preset voltage threshold value, the generator is control to decrease the amount of generated electric energy, wherein the second voltage threshold value is larger than the rated output voltage. Whether the electric power of an electric load is increased or decreased can be judged through monitoring the terminal end of the generator, and the amount of the generated electric energy of the generator can be automatically adjusted, and the terminal voltage of the generator can be controlled in a fixed fluctuation range; and therefore, the electric energy of the generator can be fully utilized, the self-consumption of the generator can be decreased as much as possible, and the utilization efficiency of the electric energy can be improved.

Description

technical field [0001] The invention relates to the technical field of generators, in particular to a method and device for intelligently adjusting power generation. Background technique [0002] Most of the existing electric vehicles are powered by batteries, and the power of the batteries is limited, so the running distance of the electric vehicles is very limited. Thus, self-generating electric vehicles came into being. [0003] A self-generating electric vehicle means that a generator is added to the original electric vehicle, and the generator and the battery can supply power for the electric vehicle at the same time. For electric vehicles, the main electrical load is the motor of the electric vehicle, and the electric power required by the motor is not constant. For example, when starting, climbing, and accelerating, the electric power required by the motor is large, and When going downhill or decelerating, the electric power required by the motor is small, and the g...

Problems solved by technology

For electric vehicles, the main electrical load is the motor of the electric vehicle, and the electric power required by the motor is not constant. For example, when starting, climbing, and accelerating, the electric power required by the motor is relatively large, When going downhill or decelerating, the electric power required by the motor is small, and the generator of the existing range-extended electric vehicle cannot control its power generation according to the actual power consumption, so the current electric vehicles generally have low working efficiency, as shown in When climbing a slope, the power is insufficient, and when decelerating or going downhill, the power generated by the generator exceeds the power consumption and the self-consumption increases and overheats
