The objects, features and functions of the present invention will be apparent to those skilled in the art from the disclosure of the present specification. It is to be noted that the present invention may be practiced or applied in other embodiments and that various modifications and changes may be made without departing from the spirit of the present invention based on the details of the description and the various aspects and applications. In addition, the drawings attached to the present invention are only for simple schematic illustration and are not drawn to actual dimensions. The following embodiments will further explain the related art of the present invention in detail, but the disclosure is not intended to limit the claims of the present invention. The description is as follows:
as shown in fig. 1, an off-grid hybrid electric dc charging station 100 according to an embodiment of the present invention includes: the system comprises a direct current charging interface 1, a hybrid electric power energy supply system 2 and a control host 3.
The dc charging interface 1 is a conductive interface for outputting dc power, and may include a dedicated charging interface for an electric vehicle, a dedicated charging interface for an electric locomotive, and/or a charging interface for a mobile phone.
The hybrid power supply system 2 includes a fuel cell power generation module 21 and an energy storage cell module 23, and the fuel cell power generation module 21 and the energy storage cell module 23 are respectively electrically connected to the dc charging interface 1 to supply electric energy.
The fuel cell power generation module 21 is a power generation device that mainly performs an oxidation-reduction reaction through oxygen or other oxidizing agents to convert chemical energy in fuel into electric energy. The Fuel Cell power generation module 21 is, for example, a Proton Exchange Membrane Fuel Cell (PEMFC), a Solid Oxide Fuel Cell (SOFC), a Molten Carbonate Fuel Cell (MCFC), or an Alkaline Fuel Cell (AFC). In the present embodiment, the fuel cell power generation module 21 is a methanol reforming hydrogen fuel cell (RMFCs), but the present invention is not limited thereto.
The energy storage battery module 23 is a secondary battery module, and can be charged and discharged repeatedly. The energy storage battery module 23 is, for example, a Lithium battery (Lithium batteries), however, the present invention is not limited thereto.
Further, the hybrid power supply system 2 further includes a solar power generation module 22 electrically connected to the dc charging interface 1. The solar power generation module 22 is used for converting sunlight into electric energy through a photoelectric effect, and has at least one solar panel and usually further includes a voltage stabilizing device (not shown).
The control host 3 is in signal connection with the direct current charging interface 1, and the control host 3 controls the direct current charging interface 1 to establish electrical connection with an external device D (including but not limited to an electric vehicle, an electric locomotive and/or a mobile phone). The control host 3 is, for example, a Local Management System (LMS), and is capable of monitoring the state of the dc charging interface 1 (for example, whether the dc charging interface is physically connected to the external device D), receiving a charging request signal t1 from a user, and controlling the dc charging interface 1 to establish an electrical connection with the external device D according to the charging request signal t1 to provide a fast charging service. The charging request signal t1 may include the user's identity information. Preferably, after the charging is completed, the control host 3 sends the financial signal t2 to the financial institution via a remote online manner such as a network, so as to perform online payment and deduction on the account of the user. In another example, it may be changed that the user must pay for unlocking first, and the control host 3 receives the charging request signal t1 to control the dc charging interface 1 to establish electrical connection with the external device D.
Preferably, the off-grid hybrid electric dc charging station 100 further includes a human-machine interface 4, which is connected to the control host 3 through a signal. The human-computer interaction interface 4 may be, for example, a combination of a display screen and keys, or a touch screen. The human-machine interface 4 can display the current status of the off-grid hybrid electric dc charging station 100, guide the user to pay for charging, and input the charging request signal t1 of the user to the control host 3 through the human-machine interface 4. In other examples, the off-grid hybrid electric dc charging station 100 does not have a fixed human-machine interaction interface 4, and instead, it takes the form of a mobile Application (APP) for the user to download to his mobile device (e.g., a mobile phone). The user inputs the charging request signal t1 from the mobile device and transmits it to the control host 3 via network, server, etc. through remote connection.
Preferably, the control host 3 preferentially controls the energy storage battery module 23 to provide power to the external device D through the dc charging interface 1, and when the energy storage battery module 23 has a small or insufficient electric quantity, the solar power generation module 22 is used to provide power to the external device D; if both are low or insufficient, the fuel cell power generation module 21 supplies power to the external device D. The electric energy generated by the solar power generation module 22 can be stored in the energy storage battery module 23 at ordinary times. The power generation raw material of the fuel cell power generation module 21 is a consumable product to be replenished, and therefore, the priority of use is low. The electric energy generated by the fuel cell power generation module 21 may be stored in the storage battery module 23 or a capacitor provided in the fuel cell power generation module 21. The energy storage battery module 23 may serve as a charge and discharge regulator.
