Methanol reforming fuel cell charging method, system and equipment, and storage medium

Abstract

The invention provides a methanol reforming fuel cell charging method, system and equipment, and a storage medium. The methanol reforming fuel cell charging method comprises the following steps: obtaining hydrogen from a methanol reformer; introducing hydrogen into a hydrogen fuel cell stack to generate electricity, and supplying electricity to a buffer cell pack and a charger; and after a charging request of a battery management module is received, determining a charging electric energy source according to the charging power of the charging request and the states of the hydrogen fuel cell andthe buffer battery pack, wherein the electric energy source is the hydrogen fuel cell and / or the buffer battery pack. The charging power is high, output power is stable, the utilization rate is high,the cost is moderate, and the methanol reforming fuel cell charging method can be applied both in a fixed mode and in a movable mode, so that the application scene is wide.

Description

technical field [0001] The invention relates to the field of new energy vehicle charging, in particular to a charging method, system, equipment and storage medium for methanol reforming fuel cells. Background technique [0002] Existing electric vehicle chargers can be divided into fixed chargers and mobile chargers. Stationary chargers use the electricity provided by the grid to charge electric vehicles, and mobile charging vehicles use the electricity stored in batteries to charge electric vehicles. It is difficult to deploy fixed chargers in places where the power cannot be increased, where the power distribution capacity is insufficient, where there is no stable power supply, and where there is not enough space. Mobile charging vehicles use batteries as energy storage media. Due to the high cost of batteries, the price per unit of electric energy is high. In addition, mobile charging vehicles need to recharge after the battery power is exhausted, which occupies the serv...

AI Technical Summary

Problems solved by technology

The charging power of the above two charging stations is limited by the power of the fuel cell, but due to the high cost of the fuel cell, it is impossible to configure a high-power fuel cell, that is, the power of the charging station is limited, and it is impossible to achieve high-power fast charging. Charge

In addition, the output power of the fuel cell fluctuates to a certain extent, which leads to the instability of the output power of the fuel cell charging station. In extreme cases, it may not be able to meet the charging power requirements of electric vehicles.

Furthermore, once the methanol-water reforming module or the fuel cell module fails, the charging station cannot provide charging services, resulting in a decrease in the utilization rate of the charging station.
