Charging station with multiple methanol-water reforming hydrogen production and power generation modules and charging method

Abstract

The invention discloses a charging station with multiple methanol-water reforming hydrogen production and power generation modules, which comprises a control device, a methanol-water storing and conveying device, at least three methanol-water reforming hydrogen production and power generation modules, an AC-DC electric power conversion device and a plurality of chargers, wherein each methanol-water reforming hydrogen production and power generation module comprises a reformer and a fuel battery, raw materials of methanol and water have a reforming hydrogen production reaction in the reformer, produced hydrogen gets into the fuel battery, the hydrogen and oxygen in the air have an electrochemical reaction in the fuel battery, and electric power output is generated; each charger feeds the instant charging power requirement quantity back to the control device in the charging process, and the control device control an appropriate number of methanol-water reforming hydrogen production and power generation modules to operate according to charging power requirement quantity information. According to the invention, an electric power source of the charging station is the multiple the methanol-water reforming hydrogen production and power generation modules, and the charging station is not subject to regional restrictions. The charging station disclosed by the invention does not need to set a primary side charger or a renewable energy storage battery, and can carry out intelligent and quick charging on equipment such as electric vehicles and the like instantly.

Description

technical field [0001] The invention relates to the technical field of charging stations, in particular to a charging station and a method with multiple sets of methanol-water reforming hydrogen production power generation modules.

AI Technical Summary

Problems solved by technology

[0005] However, the above-mentioned charging stations also have the following deficiencies: First, since the source of electricity for the charging stations is the mains power grid, it is difficult to set up charging stations in remote roads and areas where electricity is not guaranteed, and solar or wind energy is often required to obtain electricity. However, taking electricity from solar energy or wind energy is not only costly, but also unstable; second, because the charging station generally cannot directly take electricity from the grid with high power, a primary primary side charger is set up to charge the regenerative energy storage battery, and then through the regeneration Energy storage batteries charge electric vehicles with high power, but regenerative energy storage batteries are costly, low in safety, and difficult to maintain
