Fuel battery power generation, power storage and charging system and method

Abstract

The invention discloses a fuel battery power generation, power storage and charging system, and relates to the field of power supply systems. The problems that at present, charging of an electric cardepends on a power grid, the energy using efficiency is low, and environmental protection cannot be achieved are solved. According to the technical scheme, the fuel battery power generation, power storage and charging system includes a fuel battery, a battery system for storing power through an energy storage battery and an energy management platform for controlling and managing supplied power; the fuel battery is connected with a first DC / DC module, and the first DC / DC module is electrically connected to the charging end of the battery system; the first DC / DC module and the discharge end of the battery system are electrically connected to a DC charging pile; the fuel battery is also connected to a DC / AC inverter connected to the first DC / DC module in parallel, and the DC / AC inverter is connected to an AC charging pile; and the energy management platform is in communication connection with a first contactor group for controlling power on and power off of the fuel battery. The fuel battery power generation, power storage and charging system integrates power generation, power storage and charging, the load on the national power grid is reduced, energy is saved, a variety of chargingoptions are provided, and use by users is facilitated.

Description

technical field [0001] The invention relates to an electric vehicle power supply system, in particular to a fuel cell power generation, power storage and charging system and method. Background technique [0002] In recent years, the greenhouse effect caused by environmental pollution has led to drastic climate changes in various places, coupled with the rising awareness of environmental protection, countries around the world are striving to develop and promote zero-pollution power supply equipment. [0003] At present, the power supply of electric vehicles depends on the national grid, and the charging piles of electric vehicles are powered through the grid, which increases the load on the grid, and the energy utilization is not efficient and environmentally friendly, and there is still room for improvement. Contents of the invention [0004] The purpose of the present invention is to provide a fuel cell power generation, power storage, charging system and method, which in...
