Electric vehicles and systems for external power supply of electric vehicles

Abstract

The invention proposes a power supply system for electric vehicles, including: a power battery; a charging and discharging socket connected to an external load; a three-level bidirectional DC / AC module; a charging and discharging control module, one end of the charging and discharging control module It is connected to the AC terminal of the three-level bidirectional DC / AC module, and the other end of the charging and discharging control module is connected to the charging and discharging socket; the controller module is used to control the three-level bidirectional DC / AC module to convert the power battery The voltage is converted into alternating current with a preset voltage value, and is provided to an external load through the charge and discharge control module and the charge and discharge socket. The external power supply system can supply power to the outside through the electric vehicle, thereby improving the function of the electric vehicle, and using a three-level bidirectional DC / AC module, which can realize high-power charging and discharging of the power battery and improve the efficiency of charging and discharging the power battery , shorten the charge and discharge time, and bring convenience to users. The invention also provides an electric vehicle.

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...
