Problems solved by technology

[0005] The purpose of the present invention is to provide a charging system for electric vehicles, which can not only perform high-rate fast charging for electric vehicles, but also can play the role of peak-shaving and valley-filling by storing the low-valley electric energy at night and charging electric vehicles during the day, and at the same time It can also guarantee 24-hour uninterrupted power supply, which solves the problem of charging when the grid is disconnected and the problem of mains power supply

Embodiment Construction

[0015] Please refer to figure 1 Shown, the present invention will be further described below in conjunction with embodiment case.

[0016] In this implementation case, the operation modes of the power supply area 20, the energy storage area 40, the charging area 30 and the management area 10 are as follows:

[0017] The charging process of the energy storage area 40 is divided into two modes: first, after the solar energy is converted into electric energy through the solar panel 23, the voltage is adjusted to the corresponding charging voltage through the solar power generation module 24, and then the energy storage area 40 is supplemented. Second, through the grid inlet 21, the alternating current in the grid is converted into a corresponding charging voltage by the AC-DC charging module 22, and then the energy storage area 40 is supplemented with electricity.

[0018] The external charging of the charging area 30 is divided into three modes: 1. When the electric vehicle nee...

Abstract

The present invention discloses an electric vehicle charging system which comprises a power filling area, an energy storage area, a charging area and a management area. Compared with the prior art, according to the electric vehicle charging system, since the energy storage device of the energy storage area can store electrical energy of night trough and use the electrical energy for daytime electricity using peak, combined with the function of high rate rapid charging, the large energy supplement of an electric vehicle can be carried out in a short time and a grid is not affected. At the same time, the low price electrical energy in the trough is utilized effectively, the effect of peak load shifting is achieved, the system has double charging modes of energy storage area charging and grid online real-time charging, and the 24-hour charging of the charging system is ensured when the grid is limited or is repair and out.

Description

【Technical field】 [0001] The invention relates to the field of electric vehicles, in particular to an electric vehicle charging system. 【Background technique】 [0002] As a major development industry in response to energy crisis, environmental pollution, etc., the development and application of new energy vehicles have made great progress in recent years, and the number of cities dedicated to the development of new energy public transport systems is increasing day by day. Among them, electric buses using lithium-ion batteries as power sources have rapidly become a pillar of the new energy industry due to their high energy, high operating voltage, wide operating temperature range, small size, long life, and environmental protection. With the application and promotion of electric buses, the importance of supporting infrastructure has become increasingly apparent. [0003] In order to promote the industrialization of pure electric vehicles, it is increasingly important to simu...
