Embodiment Construction

[0023] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0024] At present, the inverter discharge technology has matured, but in the field of electric vehicles, there are very few products equipped with 220V external inverter output. In order to meet the diversified application needs of users and facilitate users to obtain 220V power supply anytime and anywhere, vehicle-mounted inverter technology came into being. . This application mainly solves the control problem of the external 220V inverter output of the main electric vehicle, the vehicle safety and the convenience of human-...

Abstract

The invention relates to the technical field of electric automobiles, in particular to an inverter output control method and device of an electric automobile and the electric automobile. The method comprises the steps that whether a vehicle-mounted charger of the electric automobile is connected with an inverter gun or not is detected; when the inverter gun connection signal is detected, the electric vehicle is controlled to exit the driving mode, and an electronic parking braking system of the electric vehicle is pulled up; and a vehicle-mounted battery of the electric vehicle is controlled to supply power to the external equipment at the target output voltage, and power supply is stopped when the actual electric quantity of the vehicle-mounted battery reaches the inversion discharge cut-off electric quantity. Therefore, the problems that in the prior art, the electric automobile cannot supply power to external equipment, and the power utilization convenience is poor are solved.

Description

technical field [0001] The present application relates to the technical field of electric vehicles, in particular to an electric vehicle inverter output control method and device and the electric vehicle. Background technique [0002] With the development of science and technology and the encouragement of national policies, pure electric vehicles and plug-in hybrid vehicles are developing rapidly, so higher requirements are put forward for the on-board charging system of vehicles. [0003] In related technologies, although the on-board charging system of an electric vehicle can supply power to loads in the vehicle through the charging port when the vehicle is stationary, it cannot supply power to the external equipment of the electric vehicle, which reduces the convenience of power consumption for users and needs to be improved. Contents of the invention [0004] The present application provides an inverter output control method and device for an electric vehicle, and the ...
