Smart hydrogen charging system and its control method

Recently, research and investment on the reduction of carbon dioxide emitted from automobiles using fossil fuels are being actively carried out in major developed countries around the world. Typical examples are EV (Electric Vehicle), HEV (Hybrid Electric Vehicle), PHEV (Plug-in Hybrid Electric Vehicle), FCEV (Fuel Cell Electric Vehicle), etc.

Hereinafter, EV, HEV, PHEV, FCEV, etc. may be collectively referred to as an electric vehicle (EV) (or electric vehicle).

Currently, most of the energy consumed worldwide consists of petroleum and coal, which are fossil raw materials, and in the case of automobiles, it is safe to say that all of them use oil such as gasoline or diesel. However, fossil fuels such as petroleum have limited reserves, and various exhaust gases and dust generated during combustion to obtain energy are the main culprits of environmental pollution and global warming.

Alternative energy sources that can overcome this situation include clean energy sources such as hydrogen and renewable energy such as hydropower, wind power, and solar heat. is expected to be the most desirable power source. That is, a vehicle powered by a fuel cell using hydrogen uses water and electricity generated by combining hydrogen with oxygen, so it is characterized by low noise and no exhaust gas emission. Since it is done as quickly as a gas car, it is not much different from a conventional car in terms of efficiency.

In order to use such hydrogen, a hydrogen filling station should be constructed in the same form as a gas station so that a high-pressure hydrogen gas storage container can be placed inside the vehicle and charged. However, hydrogen refueling stations currently operated take a long time to compress hydrogen, so there is a problem in that a long standby situation occurs when hydrogen charging of a hydrogen vehicle (ie, a hydrogen electric vehicle) is performed.

More specifically, as communication is connected between the charging station terminal 110 , the charging station information server 130 , and the vehicle terminal 140 (including a user terminal), a charging station (eg, a stationary hydrogen charging station, a mobile hydrogen charging vehicle, By collecting information necessary to understand the real-time status of hydrogen trailers, etc. (e.g., remaining amount of hydrogen, compression time, number of waiting cars, parts failure, charging station business hours, etc.) It is transmitted to the charging station information server 130) so that it can be shared with each other.

Accordingly, the charging station information server 130 may collect information on charging stations, automatically calculate the available charging time, and request to input an action time when an idle reason occurs.

At this time, the hydrogen remaining amount confirmation information among the information is to link the remaining hydrogen level display meter of the charging station with the server (that is, the charging station information server 130) to transmit the remaining hydrogen level information to the server in real time, and the pressure and remaining amount of the hydrogen tank You can share the current number of vehicles that can be charged by sending it to the server. In addition, the compression waiting information transmits the start and end times of the process of compressing low-pressure hydrogen to high pressure in real time to the server, and the expected charging time can be displayed by checking the general charging time. In addition, the waiting vehicle confirmation information can be shared by checking the number of vehicles waiting to be charged through a pressure sensor or a detection sensor installed in the standby position of the vehicle waiting to be charged, and then transmitted to the server. In addition, the fault information is provided when an idle cause such as compressor failure, dispenser unavailable, hydrogen shortage occurs (reason unable to recharge hydrogen), corresponding alarm occurs (e.g., compressor failure - A1, dispenser failure - matching error codes such as A2) It can be shared by sending the indicated alarm error code to the server.

(e.g. to display text messages or app notifications, etc.).

For example, the app (APP) installed in the vehicle terminal 140 (including the user terminal) lists charging stations in the order of distance centered on my location on the main screen, and displays the available charging time. In addition, when the corresponding charging station is clicked, detailed information about the charging station (e.g., the number of vehicles waiting to be charged, the number of current charging available, the time required for recompression, the number of possible charging after compression, failure, etc.) is displayed so that the user can check it.

On the other hand, as shown in FIG. 3, after placing a hydrogen trailer (ie, a shared hydrogen charging station) in a specific area (eg, an area where a stationary hydrogen charging station cannot be installed), a vehicle equipped with a compressor and a dispenser (eg, a mobile hydrogen charging station) car) to be able to charge hydrogen while moving.

At this time, the hydrogen charging station can be operated unmanned by applying CCTV and IoT systems, and in the case of a mobile hydrogen charging vehicle, the vehicle driver can perform hydrogen charging and management of the charging station.

The vehicle information is transmitted and shared to the charging station information server 130 through the communication unit 113 , or information is transmitted and shared to the charging station terminal 110 .

The charging station terminal control unit 111 performs corresponding control (eg, alarm output and hydrogen charging stop) when an abnormality is detected in the vehicle state during hydrogen charging or before hydrogen charging.

The charging station information server 130 stores vehicle information transmitted from the charging station terminal 110 for each vehicle in a database (not shown). For example, the database may store a fault code, detailed information, etc. for each vehicle, and may also store driving information for each vehicle. That is, vehicle information (eg, hydrogen charging cycle, average hydrogen charging amount, driving distance per unit hydrogen, etc.) can be collected for each vehicle, organized by date, and stored. The information for each vehicle can be used as basic data for installing a charging station, is not shared with other vehicles, and can transmit individual information of the corresponding vehicle upon a user's request.
