Fig. 1 is a block diagram of a charging device according to an embodiment of the present invention, and is applicable to a charging device.
The charging device comprises an energy storage module for storing electric energy; and a fuel cell connected to the energy storage module and a load for charging the energy storage module and for supplying power to the load.
In one embodiment, the energy storage module is a farad capacitor, also called an electric double layer capacitor. Before the charging device is used, the farad capacitor is charged by the fuel cell, the farad capacitor is fast in charging speed, the charging time is short, and the farad capacitor can reach more than 95% of the rated capacity within 10 seconds to 10 minutes. And it can provide big electric quantity output for the load, and farad capacitor and fuel cell cooperation use can provide the load required current fast when fuel cell supplies power inadequately alone, and the load that is highly suitable for having relatively high performance to adopts.
In one embodiment, the type of fuel cell may be at least one of a Direct Methanol Fuel Cell (DMFC), a solid oxide fuel cell, a hydrogen fuel cell, and a LAMINA fuel cell. The cell types of the fuel cells can be the same or different, when the fuel cells are a plurality of fuel cells, the fuel cells are sequentially connected in parallel, the power supply time can be prolonged through the parallel connection of the fuel cells, and the number of the specific fuel cells is not limited.
As shown in fig. 2, the charging method provided in this embodiment specifically includes steps 210 to 230.
In one embodiment, the fuel cell is a LAMINA fuel cell, also known as a membrane-type cell, which has a small volume to allow high performance while saving installation space. Power cords, power outlets and chargers are not required, and the load can be powered by just plugging the LAMINA fuel cell into the load. The working principle is that salt and water are used for producing hydrogen, and the hydrogen is in contact with air to generate chemical reaction so as to generate electric energy. The fuel cell can realize self power supply only by supplementing fuel.
In the present application, a plurality is understood to mean at least 2 (2 or more), that is, 2, 3 or even more.
The load may be any terminal device such as a mobile terminal, a tablet computer, a PDA (Personal Digital Assistant), a POS (Point of Sales), a vehicle-mounted computer, and a wearable device.
When the charging device is used, whether the charging device is connected with a load or not is firstly detected, for example, whether an external adapter or a USB is connected with the charging device or not can be detected, when the external adapter or the USB is connected with the charging device, the charging function of the charging device is considered to be triggered, if no external equipment capable of charging the charging device is detected to be accessed, the charging function of the charging device is considered not to be triggered, namely, the charging device is not connected with the load, and at the moment, the fuel cell charges the energy storage module, so that the energy storage module stores electric energy, and the situation that the electric quantity provided by the fuel cell is not enough to enable the load to work normally at the initial stage, namely, when the charging device just supplies power to the load is prevented. If it is detected that an external device charged by the charging device is connected, it is assumed that the charging function of the charging device has been triggered, i.e. the charging device is connected to a load, at which time the fuel cell starts to supply power to the load.
In one embodiment, when a load is powered by a fuel cell, first power information of the fuel cell and second power information required by the load are acquired. The first electric quantity information may be electric quantity information of the fuel cell acquired by the sampling detection circuit by acquiring a voltage signal of the fuel cell according to the voltage signal. The second electric quantity information is the electric quantity currently required by the load, and the electric quantity currently required by the load is obtained according to the basic information of the load and the service information, wherein the basic information of the load may include the current scene parameter information of the load. For example, when the load is a mobile phone, the scene parameter information includes any one or a combination of the following: the scene is backlight brightness parameter information of a bright screen, and the scene is backlight brightness parameter information of a dead screen. The traffic information of the load may include information of a program currently operated by the load, including any one or a combination of the following: a call program, a web browsing program, a video program, etc. The difference in the basic information or the service information of the load may cause the difference in the second power amount information.
And step 220, comparing the first electric quantity information with the second electric quantity information and outputting a comparison result.
In one embodiment, after the first electric quantity information of the fuel cell and the second electric quantity information required by the load are acquired, the first electric quantity information and the second electric quantity information are compared in size. For example, the voltage or the current of the fuel cell and the load can be compared, and if the voltage across the fuel cell is greater than the voltage across the load, a comparison result that the first electric quantity information is greater than the second electric quantity is output; and if the voltage at the two ends of the fuel cell is greater than the voltage at the two ends of the load, outputting a comparison result that the first electric quantity information is less than the second electric quantity.
And step 230, outputting a corresponding control instruction to the energy storage module according to the comparison result so that the energy storage module selects whether to supply power to the load.
In one embodiment, the control instruction is output to the energy storage module correspondingly according to the obtained comparison result, and the energy storage module executes corresponding action according to the received instruction. For example, an action of supplying power to the load or an action of not supplying power to the load is performed.
Fig. 3 is a flowchart of an embodiment, in which a corresponding control command is output to the energy storage module according to the comparison result, so that the energy storage module selects whether to supply power to the load, including:
and step 310, when the first electric quantity information is greater than or equal to the second electric quantity information, controlling the energy storage module not to supply power to the load.
And step 320, when the first electric quantity information is smaller than the second electric quantity information, controlling the energy storage module to be connected with the fuel cell in parallel to jointly supply power to the load.
In one embodiment, the charging mode of the charging device is controlled according to the comparison result, wherein the charging mode comprises that the fuel cell alone supplies power to the load, and the fuel cell and the energy storage module jointly supply power to the load. For example, when the load is a mobile phone, the voltage required by the load is 5V, and when the voltage of the fuel cell is lower than 5V, it can be determined that the fuel cell is insufficient to supply power to the load, and the energy storage unit is controlled to supply power to the load, so that the fuel cell and the energy storage unit jointly supply power to the load. When the voltage of the fuel cell is higher than 5V, for example, 6V, it can be determined that the load can be normally operated by supplying power to the load by the fuel cell alone, and then the energy storage unit is controlled not to supply power to the load. At this time, 5V of the fuel cell is supplied to the load, and the remaining 1V is charged to the energy storage unit.
Fig. 4 is a flowchart of an embodiment, in which a corresponding control command is output to the energy storage module according to the comparison result, so that the energy storage module selects whether to supply power to the load, including:
step 420 is to control the energy storage module and the fuel cell to be connected in parallel to supply power to the load together when the first electric quantity information is smaller than the first preset threshold.
In one embodiment, a first preset threshold is first set, and the first preset threshold is greater than the second power information. The specific value of the first preset threshold is not further limited. And then controlling the charging mode of the charging device according to the comparison result of the first electric quantity information and the first preset threshold value. For example: when the load is a mobile phone, the voltage required by the load is 5V, and the first preset threshold is 6V. When the voltage of the fuel cell is lower than 6V, for example, 5.2V, the energy storage unit is controlled to supply power to the load, so that the fuel cell and the energy storage unit jointly supply power to the load. When the voltage of the fuel cell is higher than or equal to 6V, which may be 6.1V, for example, the energy storage unit is controlled not to supply power to the load. At this time, 5V of the fuel cell is supplied to the load, and the remaining 1.1V is charged to the energy storage unit.
When the amount of power of the fuel cell is equal to the amount of power required by the load, if the fuel cell supplies the entire amount of power to the load, the charging mode of the charging device needs to be adjusted when the amount of power required by the load slightly changes. For example, if the second power information is slightly increased, the energy storage module needs to be controlled to supply power. Since the amount of power required by the load, i.e., the second power information, is influenced in many ways, the charging mode may be switched too frequently, and thus the charging may be unstable.
In the embodiment, the first preset threshold is set, the first preset threshold is greater than the second electric quantity information, and when the electric quantity provided by the fuel cell is less than the first preset threshold, the energy storage module and the fuel cell are controlled to supply power to the load together, so that the charging device can keep the same charging mode within a certain variation range according to the second electric quantity information, the switching times of the charging mode are reduced, and the charging stability is improved.
In one embodiment, the charging method further includes acquiring third electric quantity information of the energy storage module; and outputting alarm information when the sum of the first electric quantity information and the third electric quantity information is smaller than the second electric quantity information and/or the first electric quantity information is smaller than a second preset threshold value.
In one embodiment, the third power information is power information stored in the energy storage module, and may be, for example, a voltage value across the energy storage module. When the sum of the first electric quantity information and the third electric quantity information is smaller than the second electric quantity information or the first electric quantity information is smaller than a second preset threshold value, the fact that the fuel cell and the energy storage module jointly supply power to the load is insufficient to enable the load to work is explained, the fuel shortage of the fuel cell can be judged, at the moment, alarm information is output to prompt a user to replace a fuel package, the charging interruption is prevented, and the normal work of the load and the user experience are influenced. The specific numerical value of the second preset threshold is not further limited and is set according to the actual situation. For example, the second preset threshold may be 2%, 5%, or other values of the total amount of electricity that the fuel cell can provide in the initial state.
The charging device is connected to the load when the load is low or no. For example, the load can be a mobile phone, when the first electric quantity information is larger than the second electric quantity information, the fuel cell releases electric energy, one part of the electric energy is supplied to the load, the rest electric energy is used for charging the farad capacitor, and the farad capacitor stores the electric energy rapidly; and when the first electric quantity information is not larger than the second electric quantity information, the fuel cell supplies power to the load, and the farad capacitor does not discharge. When the load needs large electric energy, such as a user needs to turn on a flash lamp, start or navigate, the mobile phone needs to provide large current to support normal use of the function, and if the current provided by the fuel cell is insufficient, the farad capacitor automatically releases the stored electric energy and supplies power to the load together with the fuel cell. The farad capacitor has fast current releasing speed and can discharge large current, so that the load can work normally.
The fuel cell can provide lasting low current, and the farad capacitor can provide short-time high current, so that the performance problems of long duration of the endurance of the mobile phone and high power consumption of the load can be well solved by combining the fuel cell with the farad capacitor. Wherein the fuel cell provides the longest duration of travel and the farad capacitor provides a short auxiliary power when the high power consuming function requires a large amount of power when the load needs to be used.
In the embodiment, when the fuel cell supplies power to the load, the first electric quantity information of the fuel cell and the second electric quantity information required by the load are acquired, the first electric quantity information and the second electric quantity information are compared, the comparison result is output, and the corresponding control instruction is output to the energy storage module according to the comparison result, so that the energy storage module can select whether to supply power to the load. When the electric energy that fuel cell provided alone is not enough, control energy storage module and fuel cell are the load power supply jointly, can increase charging device's output current, make fuel cell can independently act as external power source, have replaced the lithium cell power supply, and is more energy-concerving and environment-protective.
It should be understood that although the various steps in the flowcharts of fig. 2-4 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
