Description

Mobile charging station and method with multiple sets of methanol water reforming hydrogen production power generation modules

technical field

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

Background technique

Currently, electrically powered vehicles such as electric vehicles, plug-in hybrid vehicles are rapidly increasing in use. Because electric vehicles are rapidly increasing in use, mobile charging stations for charging auxiliary batteries installed in electric vehicles are being adopted.

In the prior art, mobile charging stations usually use mobile batteries and internal combustion engine generators as sources of power. Due to the limited storage capacity of mobile batteries, they cannot continue to charge multiple electric vehicles. Therefore, internal combustion engines are used to generate electricity. Compared with mobile charging stations using mobile batteries, mobile charging stations with mobile phones are more suitable for charging electric vehicles. However, mobile charging stations using internal combustion engine generators also have the following defects: one, they are not environmentally friendly, they need to burn gasoline or diesel, and the exhaust gas pollutes the environment; Smaller, it is difficult to realize on-demand charging, so mobile charging stations generally cannot take power directly from the internal combustion engine generator, but need to set up the primary primary side charger (for charging the regenerative energy storage battery), the regenerative energy storage battery and the secondary secondary Side fast charger (charging for electric vehicles), its working principle is: usually move the internal combustion engine generator to store and charge the regenerative battery through the primary primary side charger. Current and voltage, through the secondary side fast charger to quickly charge the electric vehicle; third, from the chemical energy of gasoline or diesel to mechanical energy, and then from mechanical energy to electrical energy, the energy conversion path is long, the loss is large, and the efficiency is low .

Chinese invention patent application 201410209948.8 discloses a fuel cell mobile charging device. The fuel cell power generation part includes a methanol fuel storage tank, a methanol hydrogen generator, and a fuel cell power stack; the battery energy storage part includes a high-efficiency lead-acid battery pack, DC charging Controller and AC inverter; the fuel cell power generation stack is connected to the lead-acid battery pack through the DC charging controller, the lead-acid battery pack is connected to the DC charging pile, and at the same time is connected to the AC charging pile through the AC inverter. The fuel cell mobile charging device uses methanol as a raw material to produce hydrogen, and then uses fuel cells to generate electricity, which is environmentally friendly and does not pollute the environment, and chemical energy is directly converted into electrical energy, with short energy conversion paths, small losses, and high efficiency. However, since the fuel cell mobile charging device uses a single fuel cell power stack, it is difficult to meet the fast and high-power charging of electric vehicles, or it is difficult to meet the charging of multiple electric vehicles at one time, and it is still necessary to conduct the first charging of the lead-acid battery pack. Only then can the electric vehicle be charged through the lead-acid battery pack, which cannot be charged on demand, which is inconvenient. In addition, the lead-acid battery pack has high cost, low safety, and difficult maintenance.

Chinese invention patent application 201410750440.9 discloses a portable vehicle-mounted fuel cell charging power supply for electric vehicles. It consists of two parts, the stack is connected to the hydrogen flow controller through the cable, the hydrogen flow controller is connected to the bottom of the stack through the intake pipe, the charging gun socket is provided in the middle of the shell, and the other end of the hydrogen flow controller Connected to the hydrogen tank. Although the vehicle-mounted fuel cell charging power supply does not use energy storage batteries such as lead-acid battery packs, the vehicle-mounted fuel cell charging power supply still uses a single fuel cell power stack, so it is difficult to meet the fast and high-power charging of electric vehicles, or it is difficult to meet the charging requirements at one time. Multiple electric car charging.

Continuing from the above, the mobile charging device or charging power supply using a single fuel cell power stack also has the following defects: First, in order to increase the power of the fuel cell, the hydrogen generator and the fuel cell power stack are often made relatively large, slow start-up, hydrogen production It is difficult to control parameters such as temperature, gas flow, gas pressure, and power generation speed; second, its overall energy consumption is relatively large, and the raw material consumption of methanol and water is high, and the utilization rate is high; for example, when the demand for instant charging power is small, For example, when charging a small to-be-charged device or charging a single to-be-charged device, a single relatively high-power hydrogen generator and fuel cell power stack are still required to work; When the machine and the fuel cell power stack break down, the whole mobile charging device or the charging power supply can only stop working, which is limited to a paralyzed situation.
