Abstract

The invention provides an external electric automobile power supply system which comprises a power battery, a charging / discharging socket, a bidirectional direct current / direct current (DC / DC) module, a bidirectional direct current / alternating current (DC / AC) module, a charging / discharging control module and a controller module, wherein the charging / discharging socket is connected with an external load; the controller module is connected with the charging / discharging control module; the controller module is used for controlling the bidirectional DC / DC module and the bidirectional DC / AC module to convert the voltage of the power battery into an alternating current with a preset voltage value and providing the voltage for the external load through the charging / discharging control module and the charging / discharging socket. The functions of the electric automobile can be increased, so that the electric automobile can charge the external load, and the application applicability of the electric automobile is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle power supply system and an electric vehicle with the 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. However, the popularization of electric vehicles still faces some problems. Among them, high mileage and fast charging technology have become a major issue in the promotion of electric vehicles. problem. [0003] At present, most electric vehicles use large-capacity batteries. Although the battery life of electric vehicles can be improved, the same large-capacity batteries also bring about the problem of long charging time. Although professional DC charging stations can quickly charge batteries, the high cost and large footprint make it difficult to popularize such infrastructure. At...
