Electric automobile and system of electric automobile for outwards supplying power

Abstract

The invention provides a system of an electric automobile for outwards supplying power. The system comprises a power battery, a charge-discharge socket, a three-level bi-directional DC/AC (Direct Current/ Alternating Current) module, a charge-discharge control module and a controller module, wherein the charge-discharge socket is connected with an externally connected load; one end of the charge-discharge control module is connected with the alternating current end of the three-level bi-directional DC/AC module, and the other end of the charge-discharge control module is connected with the charge-discharge socket; the controller module is used for controlling the three-level bi-directional DC/AC module to convert the voltage of a power battery into the alternating current of a preset voltage value, and providing the alternating current to the externally connected load through the charge-discharge control module and the charge-discharge socket. The system for outward supplying power can outwards supply power through the electric automobile, so that the function of the electric automobile is improved; the three-level bi-directional DC/AC module is adopted, so that the power battery is large power charged and discharged, the efficiency for charging and discharging the power battery is improved, the charging and discharging time is shortened, and convenience is brought for users. The invention also provides the electric automobile.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle external power supply system and an electric vehicle with the electric vehicle external power supply system. Background technique [0002] With the development of science and technology, environmentally friendly and energy-saving electric vehicles are playing the role of replacing fuel vehicles. Most electric vehicles use large-capacity power batteries. Although the battery life of electric vehicles can be improved, at the same time, large-capacity power batteries bring the problem of long charging time. Moreover, the idle electric energy in the power battery of the electric vehicle cannot be fully utilized at present. [0003] Therefore, electric vehicles in the prior art need to be improved. Contents of the invention [0004] The object of the present invention is to solve at least one of the above-mentioned technical drawbacks. [0005] For t...
