Example Embodiment

[0038] Example 1

[0039] According to an embodiment of the present invention, a method embodiment of a power regulation method for an electric vehicle is provided. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions , and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0040] figure 1 is a power regulation method for an electric vehicle according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0041] Step S102, obtaining the remaining power percentage of the power battery system.

[0042] In the above step S102 of the present application, the power regulating device of the electric vehicle needs to obtain the remaining power percentage (State of Charge, SOC for sho...

Example Embodiment

[0072] Example 2

[0073] According to an embodiment of the present invention, there is also provided a power regulation device for an electric vehicle for implementing the above power regulation method for an electric vehicle, such as Figure 4 As shown, the power regulating device of the electric vehicle includes: a first data collector 402 , a processor 404 and a power regulator 406 .

[0074] Wherein, the first data collector 402 is used to obtain the remaining power percentage of the power battery system; the processor 404 is connected to the first data collector 402 and used to determine the remaining power percentage according to a pre-divided percentage interval The percentage range to which it belongs; the power regulator 406 is connected to the processor 404 and is used to adjust the energy recovery power of the energy recovery system and / or the power generation power of the range extender system according to the percentage range to which the remaining power percenta...

Abstract

The invention discloses a power regulation method and device for an electric automobile and an electric automobile. The method includes: obtaining the percentage of the remaining electric quantity of a power battery system; according to percentage intervals divided in advance, determining the percentage interval to which the percentage of the remaining electric quantity belongs; and according to the percentage interval to which the percentage of the remaining electric quantity belongs, regulating the energy recovery power of an energy recovery system and/or the generated power of a range extender system. The power regulation method for the electric automobile solves the technical problem that shortened service life of a power battery system which is caused by frequent large-current charging of a range extender system to the power battery system.

Description

technical field [0001] The present invention relates to the field of power adjustment, in particular, to a power adjustment method and device for an electric vehicle and the electric vehicle. Background technique [0002] At present, the control of the range extender system (range extender system, which refers to the power generation device mounted on the electric vehicle to assist the vehicle to charge and extend the driving range) is relatively simple for the range-extended electric vehicle, and the power battery system and the range extender are in the same position. In a relatively independent operating state, the range extender uses fixed power to assist power generation. [0003] However, in this way, the range extender system will frequently charge the power battery system with high current, resulting in problems such as power battery attenuation, reduced service life, and poor fuel economy. [0004] For the above problems, no effective solution has been proposed yet...
