Example 1
Referring to fig. 1, fig. 1 is a flowchart illustrating an electric energy output method according to an embodiment of the present invention. The power output method in fig. 1 is applied to a power supply device including a power supply source and an energy storage device, the power supply device is connected with an electrical load, and the power output method in fig. 1 includes the following steps:
and 101, acquiring the working state of the electric load.
The electric load is composed of a plurality of load devices which need to use electric energy, for example, the electric load can be composed of load devices such as an electric water heater, an electric heater and a refrigeration device. The power supply equipment needs to acquire the working state of the power utilization load in real time, wherein the working state comprises an opening state and a closing state, so that whether electric energy needs to be provided for the power utilization load or not is determined through the working state of the power utilization load, and the reliable operation of the load equipment is ensured.
It should be understood that the electrical load includes a load device configured according to actual requirements, the energy storage device is any device for storing electrical energy and outputting electrical energy, and the power supply source is any device for supplying electrical energy to the electrical load, and is not limited herein. For the convenience of understanding of the present application, in the present embodiment, the power supply is a device connected to the mains for outputting 220V ac power. The energy storage device is composed of a preset number of energy storage batteries, the energy storage batteries can adopt a connection mode of multiple strings of single parallel connection, multiple strings of multiple parallel connection and the like, and the energy storage batteries can adopt a rechargeable battery, a flow battery, a flywheel battery, a super capacitor and the like, which is not described herein in detail.
And 102, if the working state of the power load is a closed state, storing the electric energy output by the power supply to the energy storage device.
In this embodiment, energy memory receives structural design restriction, can't carry out long-time output electric energy. The power supply connected with the mains supply can output electric energy for a long time, and if the working state of the power utilization load is the closed state, the power supply equipment can not output the electric energy to the power utilization load and store the electric energy output by the power supply to the energy storage device. The power supply is connected with the energy storage device, and after the electric energy stored in the energy storage device is completely released, a maintainer is not required to replace the new energy storage device, the storable electric energy is provided for the energy storage device by the power supply, and the long-time reliable operation of the energy storage device is ensured.
As an example, if the operating state of the electrical load is an off state, the storing the electrical energy output by the power supply to the energy storage device includes:
acquiring the state of charge of the energy storage device, wherein the state of charge comprises a non-full state and a full state;
and if the working state of the electric load is the off state and the charge state of the energy storage device is the non-full state, storing the electric energy output by the power supply to the energy storage device until the charge state of the energy storage device is the full electric energy state.
And acquiring the charge state of the energy storage device, wherein the charge state comprises an under-full state and a full-electric state. And if the working state of the power load is the closed state and the energy storage device is in the non-full power state, storing the electric energy output by the power supply to the energy storage device until the energy storage device is switched from the non-full power state to the full power state. If the energy storage device is in a full electric energy state, the power supply does not output electric energy to the energy storage device, and the energy storage device is prevented from being damaged due to faults of overcurrent, overvoltage and the like.
And 103, if the working state of the electric load is the starting state and the working power of the electric load is greater than the rated power of the power supply, mixing the electric energy output by the power supply and the energy storage device and outputting the electric energy to the electric load.
In this embodiment, the rated power of the alternating current supplied by the power supply does not exceed 2200W. When the electric load is in an on state and the working power of load equipment included in the electric load exceeds 2200W, the working power of the electric load is larger than the rated power of the power supply, and the power supply and the energy storage device output electric energy to the electric load at the same time. The electric energy output by the energy storage device compensates the part of the electric load with power exceeding 2200W, so that the reliable operation of the load equipment is ensured, and the electrical accident caused by the working power of the load equipment exceeding the rated power of the power supply is avoided. Meanwhile, the design of household power wiring does not need to be adjusted and modified, so that electrical accidents caused by adjustment and modification of power wiring are avoided, and further fires caused by the electrical accidents are avoided.
It should be understood that, if the working power of the instant electric load is less than or equal to the rated power of the power supply, that is, the working power of the instant electric load does not exceed 2200W, the electric energy output by the power supply can be directly output to the electric load without the energy storage device outputting the electric energy to the electric load.
As an example, the power supply apparatus further includes a renewable power source, and the storing the electric energy output by the power supply source to the energy storage device includes:
the electric energy output by the power supply and the renewable power supply is mixed and stored in the energy storage device;
the hybrid output of power supply and the electric energy of energy memory output is to with electric load, includes:
and mixing the electric energy output by the power supply, the energy storage device and the renewable power supply and outputting the electric energy to the electric load. Referring to fig. 2, fig. 2 is a schematic structural diagram of a power supply device according to an embodiment of the present invention. The power supply apparatus 200 includes a power supply 210, an energy storage device 220, a renewable power source 230, and an electric load 300.
The power supply 210 is connected to the electrical load 300 through the energy storage device 220, and the power supply 210 is also directly connected to the electrical load 300. The renewable power source 230 is connected to the energy storage device 220 and the electric load 300, respectively.
If the electric load 300 is in the off state, the electric energy output by the power supply 210 and the renewable power supply 230 is stored in the energy storage device 220 in a mixed manner, and the utilization rate of the renewable energy is improved and the load of the power supply 210 is reduced by storing the electric energy generated by the renewable power supply 230. If the electric load 300 is in the on state, the electric energy output by the power supply 210, the energy storage device 220 and the renewable power source 230 is mixed and output to the electric load 300. The electric energy output by the energy storage device 220 and the renewable power source 230 compensates the part of the electric load power exceeding 2200W, so that the reliable operation of the electric load 300 at the working power is ensured. Meanwhile, the renewable power supply 230 outputs electric energy, so that the output load of the energy storage device 220 is reduced, and the time for the energy storage device 220 to output electric energy is prolonged.
It should be understood that the renewable power source 230 is a device for converting renewable energy sources such as solar energy, wind energy and the like into electric energy, and the type of the renewable power source 230 is set according to actual requirements, and is not limited herein. If the renewable power source 230 cannot store the electric energy obtained by converting the renewable energy, the electric energy obtained by converting the renewable energy from the renewable power source 230 is output to the energy storage device 220, and the electric energy obtained by converting the renewable energy is stored by the energy storage device. In addition, it should be understood that the power supply apparatus 200 may select whether to provide the renewable power source 230 according to actual requirements, and is not limited herein. If the power supply device 200 does not include the renewable power source 230, the power supply 210 and the energy storage device 220 output the electric energy to the electric load 300 at the same time, so that the electric load 300 can operate reliably at the working power, which is not described herein again. Whether the renewable power source 230 is provided does not affect the functional implementation of the power supply apparatus 200 of the present application.
In an alternative example, the power supply device includes a renewable power source, and the electric energy output by the renewable power source can be output to the electric load. The hybrid output of the electric energy output by the power supply, the energy storage device and the renewable power supply to the electric load comprises:
configuring a first power output ratio among the power supply, the energy storage device and the renewable power source;
and mixing the electric energy output by the power supply, the energy storage device and the renewable power supply based on the first electric energy output proportion to obtain power supply electric energy, and outputting the power supply electric energy to an electric load.
The first power output ratio is set according to actual requirements, and is not limited herein. For the convenience of understanding of the present application, in this embodiment, if the total electric energy with the power of 2444W needs to be output to the electrical load, the power supply is configured to output the electric energy with the proportion of 90% of the total electric energy, the energy storage device outputs the electric energy with the proportion of 4% of the total electric energy, and the renewable power source outputs the electric energy with the proportion of 6% of the total electric energy, so as to obtain the first electric energy output proportion. And mixing the electric energy output by the power supply, the energy storage device and the renewable power supply based on the first electric energy output proportion to obtain the power supply electric energy. Specifically, the hybrid power supply outputs 2200W of electric energy, the energy storage device outputs 97.6W of electric energy, and the renewable power supply outputs 146.4W of electric energy, so as to obtain 2444W of power supply electric energy. The power supply electric energy is output to the electric load, and the reliable operation of the electric load is ensured. Compared with the power supply, the energy storage device and the renewable power supply which output electric energy with the same size, the energy storage device and the renewable power supply are configured to output low-proportion electric energy, so that the output load of the energy storage device and the renewable power supply can be reduced, and the duration of the continuous output of the electric energy of the energy storage device and the renewable power supply is prolonged.
It should be understood that, in the process of outputting the power supply electric energy to the electric load, if the energy storage device cannot continuously output the electric energy, the renewable power source outputs the electric energy with a proportion of 10% of the total electric energy, and if the renewable power source cannot continuously output the electric energy, the energy storage device outputs the electric energy with a proportion of 10% of the total electric energy, so that the power of the electric energy output by the power supply device is equal to the working power of the electric load, thereby realizing multi-electric-energy complementation, ensuring the reliable operation of the electric load, and avoiding the occurrence of electrical accidents.
In an alternative example, the power supply device includes a renewable power source, and the electric energy output by the renewable power source can be output to the energy storage device. The hybrid storage of the electric energy output by the power supply to the energy storage device includes:
configuring a second power output ratio between the power supply and the renewable power source;
and mixing the electric energy output by the power supply and the renewable power supply based on the second electric energy output proportion to obtain stored energy electric energy, and storing the stored energy electric energy to the energy storage device.
The second power output ratio is set according to actual requirements, and is not limited herein. When a second power output proportion between the power supply and the renewable power supply is configured, the renewable power supply can be configured to output a low proportion of power. And mixing the electric energy output by the power supply and the renewable power supply based on the second electric energy output proportion to obtain stored energy electric energy, and storing the stored energy electric energy to the energy storage device. The electric energy output by the renewable power supply is stored in the energy storage device, the renewable energy sources such as solar energy, wind energy and the like are effectively utilized, and the output load of the power supply is reduced.
It should be understood that, in the process of storing the obtained stored energy into the energy storage device, if the renewable power supply cannot output the energy continuously, the power supply outputs all the energy required by the energy storage device.
As an example, the mixing the electric energy output by the power supply and the energy storage device to the electric load includes:
acquiring a power supply mode of the power utilization load, wherein the power supply mode comprises direct current power supply and alternating current power supply;
when the power supply mode of the electric load is direct current power supply, mixing the electric energy output by the power supply and the energy storage device into direct current power supply current, and outputting the direct current power supply current to the electric load;
when the power supply mode of the power load is alternating current power supply, the power supply and the electric energy output by the energy storage device are mixed into alternating current power supply current, and the alternating current power supply current is output to the power load.
Usually, a power supply source connected to a commercial power outputs an alternating current, and an energy storage device outputs a direct current, which requires obtaining a power supply mode of each load device included in an electric load. Specifically, when the power supply mode of the load device included in the electrical load is Direct Current, the Alternating Current output by the power supply is converted into Direct Current through an AC (Alternating Current) -DC (Direct Current) conversion circuit, so that the power supply device outputs the Direct Current to the electrical load. When the power supply mode of the load equipment included in the electric load is alternating current power supply, the direct current output by the energy storage device is converted into alternating current through the DC-AC conversion circuit, so that the power supply equipment outputs the alternating current power supply current to the electric load.
It should be understood that, if the electrical load includes a load device whose power supply mode is dc power supply and a load device whose power supply mode is ac power supply, the power supply device outputs a dc power supply current to the load device whose power supply mode is dc power supply in the electrical load and outputs an ac power supply current to the load device whose power supply mode is ac power supply in the electrical load. In addition, if the renewable power supply is set, whether to convert the output current of the renewable power supply is determined according to the power supply mode of the power load, which is not described herein.
As an example, the method further comprises:
and when the energy storage device is detected to be in fault, the electric connection between the energy storage device and the power supply is cut off.
And in the operation process of the power supply equipment, the state of the energy storage device is acquired in real time. When the faults of short circuit, overhigh temperature and the like of the energy storage device are detected, the electric connection between the energy storage device and the power supply is cut off, and the serious electrical accident caused by the damage of the power supply equipment by the failed energy storage device is avoided. It should also be appreciated that if a renewable power source is provided, the connection of the energy storage device to the renewable power source is cut off when a failure of the energy storage device is detected.
It should be understood that the power supply device may also include other devices such as a processor, a memory, etc., and the power supply device may also include other circuits such as a detection circuit, a control circuit, etc., and the other devices and circuits are set according to actual requirements, and are not limited herein.
The application provides an electric energy output method, which is applied to power supply equipment comprising a power supply and an energy storage device, wherein the power supply equipment is connected with an electric load, and the method comprises the following steps: acquiring the working state of the power utilization load; if the working state of the electric load is the closing state, the electric energy output by the power supply is stored to the energy storage device; and if the working state of the power load is the starting state and the working power of the power load is greater than the rated power of the power supply, the power supply and the electric energy output by the energy storage device are mixed and output to the power load. When the working power of the electric load exceeds the rated power of the power supply, the stored electric energy output by the energy storage device supplements power for the electric load, and the load equipment is ensured to reliably run at the working power. Meanwhile, in the power supply process of the power utilization load, the design of household power wiring does not need to be adjusted and modified, and the electrical accidents caused by adjustment and modification of the power wiring are avoided.
