Abstract

The present invention relates to a hybrid energy system for charging an electric vehicle and a monitoring device thereof. The hybrid energy system comprises multiple solar arrays, a solar controller, an AC / DC rectifier controller, a battery pack, a DC / DC inverter controller and a DC charging pile, wherein, the solar controller is connected to the multiple solar arrays and is used for converting solar energy into direct current, the AC / DC rectifier controller is connected to the mains supply and is used for converting the alternating current into direct current, the AC / DC rectifier controller, the solar controller and the battery pack provide high voltage direct current to be the input of the DC / DC inverter controller, the DC / DC inverter controller outputs the direct current into the DC charging pile. According to the invention, through the isolation effect of the DC / DC inverter controller, the influence on the state grid is minimized when the DC charging pile or the electric vehicle is failed, the power supply safety of a non-electric vehicle and other important loads is ensured, and the operation safety of the whole system is improved.

Description

technical field [0001] The invention relates to the technical field of power supplies, and more specifically, relates to a hybrid energy system for charging electric vehicles and a monitoring device thereof. Background technique [0002] In recent years, with the vigorous development of the electric vehicle business, a large number of car charging piles have emerged, but these car charging piles are powered by the mains. With the gradual maturity of solar energy technology, a photoelectric hybrid power supply system for powering servers in computer rooms has emerged. Therefore, it is necessary to develop a photoelectric hybrid power system that combines solar energy and commercial power to charge electric vehicles. However, it faces the following problems: [0003] First of all, the existing fast charging of electric vehicles has a great impact on the security of the national grid, because the previous electric vehicle charging system is to input the mains power to the AC / ...
