[0051] Example 1

[0052] See also Figure 1 , Figure 1 A flow chart of a power supply control method provided in an embodiment of the present application, which can be used to power various devices to be charged through multiple energy sources to achieve flexible scheduling and use of energy, and the method includes: S101~S103.

[0053] S101. When a power generation device charges a device to be charged, determine whether the power generation power of the power generation device is greater than a preset charging power of the device to be charged; if the power generation power is less than or equal to the preset charging power, control a power supply device to supply power to the device to be charged.

[0054] In some charging stations related to electric vehicle charging, in order to reduce the cost of charging, the charging station is usually set up with integrated photovoltaic storage and charging. Photovoltaic storage and charging integration is a smart charging station that integrates photovoltaic power generation, energy storage and charging piles. In photovoltaic charging integration, power supply equipment usually refers to energy storage equipment, such as energy storage batteries, etc., and can also be combined with other power supply methods, such as generator power generation and power supply by grid equipment, etc.

[0055] Therefore, the power generation equipment in this embodiment usually refers to the photovoltaic power generation equipment in the integrated light storage and charging. The power generation cost of photovoltaic power generation equipment is low, and it uses clean energy such as solar energy. Therefore, when there is a device to be charged, such as an electric car, at the charging pile, the photovoltaic power generation equipment is preferentially controlled to charge the device to be charged. If the power generation power of the photovoltaic power generation equipment cannot meet the preset charging power of the device to be charged, other power supply equipment is used together with the power generation equipment to power the device to be charged.

[0056] Since the operation of the equipment inside the charging station also consumes a certain amount of electricity, if the generated power is exactly equal to the preset charging power, there may be a power shortage. Therefore, the generated power needs to be greater than the preset charging power to meet the charging needs of the device to be charged. In some scenarios, users can also set an internal equipment operating power according to the operation of the equipment inside the charging station, and use the difference between the generated power and the internal equipment operating power as the actual generated power to determine whether the actual generated power meets the preset charging power.

[0057] In one embodiment, if there is no device to be charged that needs to be charged at present, it is determined whether the energy storage device needs to be charged, that is, it is determined whether the energy storage device is in a charging mode. If it is in a charging mode, the energy storage device is charged by a power generation device. After the energy storage device is charged, during the peak charging period, if the power generation power of the power generation device is insufficient, the electric energy stored in the energy storage device can be used to charge the device to be charged.

[0058] In order to more conveniently determine whether the energy storage device needs to be charged, a preset capacity or preset SOC can be set for the energy storage device. SOC refers to the state of charge of the energy storage device, which is mainly used to indicate the remaining capacity of the energy storage device. When the current SOC of the energy storage device is lower than the preset SOC, it is determined that the energy storage device is in the charging mode. When the current SOC of the energy storage device is greater than or equal to the preset SOC, it is determined that the energy storage device does not need to be charged. If the energy storage device does not need to be charged, the power generation equipment can be controlled to supply power to the power grid equipment.

[0059] S102: Acquire the power supply power of the power supply device, acquire the total charging power according to the generated power and the power supply power, and determine whether the total charging power is greater than the preset charging power.

[0060] When it is determined that the power generation power of the power generation equipment is insufficient, the power generation equipment and the power supply equipment are used to charge the device to be charged at the same time, and the total charging power of the power generation equipment and the power supply equipment is obtained, and then it is determined whether the total charging power can meet the preset charging power of the device to be charged.

[0061] S103: If the total charging power is less than or equal to the preset charging power, adjust the preset charging power to a first charging power, where the first charging power is less than or equal to the total charging power.

[0062] In order to improve the charging efficiency of charging piles, a variety of power supply equipment are usually set up, and power grid equipment is usually a necessary one. Under normal circumstances, the power grid equipment alone can meet the charging needs of the device to be charged.

[0063] However, during some peak periods of electricity consumption, due to the large number of devices to be charged and power-consuming devices, the grid pressure is large, which may cause the power supply provided by the grid equipment to be small. At this time, the power generation equipment and the grid and other power supply equipment combined cannot meet the preset charging power of all devices to be charged. In order to reduce the pressure on the grid, the preset charging power of the devices to be charged can be appropriately adjusted to the first charging power, which is less than or equal to the total charging power.

[0064] The charging power of the charging pile and the preset charging power of the device to be charged are usually matched. Moreover, the preset charging power of the device to be charged is usually fixed, generally the full power when the device to be charged is charged. Therefore, when it is necessary to reduce the preset charging power, it is usually adjusted through the charging pile, that is, reducing the charging power of the charging pile.

[0065] In this embodiment, the power generation equipment is used to charge the device to be charged first. When the power generation equipment does not meet the preset charging power of the device to be charged, the power supply equipment is called to supply power to the device to be charged. If the power of the power generation equipment and the power supply equipment cannot meet the preset charging power, the preset charging power is adjusted. In this embodiment, when charging the device to be charged, the flexible scheduling and use of multiple energy sources are realized, and the problem of insufficient power supply during peak power consumption is also solved.

[0066] See also Figure 2 , step S101 also includes steps S1011 to S1012.

[0067] S1011. According to a preset priority, control one of the energy storage device and the power grid device to supply power to the device to be charged.

[0068] S1012, or, controlling the energy storage device and the power grid device to supply power to the device to be charged.

[0069] In the integrated photovoltaic storage and charging system, energy storage equipment is one of the necessary power supply equipment, and power grid equipment is usually also a necessary power supply energy source. In addition, other power supply equipment, such as generators, can also be configured according to needs.

[0070] When the power generation of the power generation equipment is insufficient, the power supply equipment can be controlled to supply power to the device to be charged according to the preset priority. The priority is usually determined based on the cost. The power supply costs of each power supply equipment are compared first to determine the corresponding priority of each power supply equipment. In order to control each power supply equipment individually or in combination with each other, the power supply equipment can be supplied to the device to be charged in a descending order of priority.

[0071] See also Figure 3 , step S101 also includes steps S1013 to S1014.

[0072] S1013: Obtain a first power supply power of the energy storage device, obtain a first total charging power according to the first power supply power and the power generation power, and determine whether the first total charging power is greater than the preset charging power.

[0073] S1014: If the first total charging power is greater than the preset charging power, control the energy storage device to supply power to the device to be charged.

[0074] For the integrated photovoltaic storage and charging system, the electric energy in the energy storage device is usually provided by photovoltaic power generation equipment, which is relatively low in cost. Therefore, the priority of the energy storage device is generally higher than that of the power grid equipment. When the power generation power of the power generation equipment is insufficient and the power supply equipment is needed, the power supply of the energy storage device can be given priority. Then add the power generation power of the power generation equipment to the first power supply power of the energy storage device to obtain the first total charging power. If the first total charging power is greater than the preset charging power of the device to be charged at this time, it means that the power generation equipment and the energy storage device can meet the charging needs of the device to be charged, and no other equipment is needed to supply power.

[0075] In one embodiment, the controlling the power supply device to supply power to the device to be charged further includes:

[0076] If the first total charging power is less than or equal to the preset charging power, the power grid device is controlled to supply power to the device to be charged.

[0077] If the power generation device and the energy storage device jointly charge the device to be charged, and their first total charging power cannot meet the preset charging power of the device to be charged, it is necessary to control the power grid device to also jointly supply power to the device to be charged.

[0078] For example, when the power generation of the power generation equipment is insufficient, the power of the energy storage equipment is insufficient, or the number of devices to be charged is large, it may cause the first total charging power to be insufficient. In order not to affect the normal charging of the devices to be charged, it is necessary to control other power supply equipment, such as power grid equipment, to provide supplementary power supply.

[0079] See also Figure 4 , step S102 includes steps S1021 to S1022.

[0080] S1021. Obtain a second power supply power of the power grid device.

[0081] S1022. Obtain a second total charging power according to the generated power, the first power supply power, and the second power supply power.

[0082] Since the power supply order of the power supply equipment in the present application is arranged according to priority, therefore, when the power generation power of the power generation equipment is insufficient, the total charging power of the power generation equipment and all the power supply equipment can be calculated once each time a power supply equipment is added to supply power, so as to determine whether the total charging power meets the preset charging power of the device to be charged.

[0083] For example, the priorities of power supply devices ABCD are from high to low. If a power supply device A is added, the total charging power of the power generation device and power supply device A is calculated. If two power supply devices A and B are added, the total charging power of the power generation device and power supply devices A and B is calculated. And so on. In this way, the charging needs of the devices to be charged can be met with the least equipment, avoiding energy waste.

[0084] In some cases, if the power generation equipment and power supply equipment C are used together for power supply, or if the power generation equipment and power supply equipment A and B are used together for power supply, the charging demand of the device to be charged can be met, and the cost is lower when the power generation equipment and power supply equipment C are used. Since the preset power supply power is flexible and changeable, and the priority of the power supply equipment may be compared separately, when using a combination of multiple energy sources for power supply, the power supply cost after the combination can be calculated first to determine the priority of different power supply equipment combinations, so as to achieve flexible use and matching of energy and reduce power supply costs.

[0085] In one embodiment, after determining whether the power generation power of the power generation device is greater than the preset charging power of the device to be charged, the method includes:

[0086] If the generated power is greater than the preset charging power, determining whether the power supply device is in a state to be charged;

[0087] If the power supply device is in the waiting-to-be-charged state, the power generation device is controlled to charge the power supply device.

[0088] When there are fewer devices to be charged, or the power generation effect of the power generation equipment is better, the power generation power may be greater than the preset charging power of the device to be charged. In order to avoid energy waste, if the power supply equipment needs power supply at this time, the power generation equipment can be controlled to charge the power supply equipment.

[0089] When photovoltaic power generation equipment supplies power to energy storage equipment, it usually needs to be converted through a photovoltaic inverter. Therefore, when it is determined that the energy storage equipment needs to be charged, it is necessary to first determine whether the photovoltaic inverter is turned on. If it is not turned on, it is necessary to control the photovoltaic inverter to turn on first before controlling the photovoltaic power generation equipment to charge the energy storage equipment. When the energy storage equipment is charged, the photovoltaic inverter is controlled to turn off.

[0090] In some cases, in order to allow the energy storage device to be charged and discharged at any time, a corresponding overcharge protection device can also be set for the energy storage device to prevent the energy storage device from continuing to charge after charging is completed, that is, the photovoltaic inverter is not turned off after the energy storage device is charged.

[0091] In one implementation, the power supply device includes an energy storage device, and controlling the power generation device to charge the power supply device includes:

[0092] Acquire a first excess generated power according to the generated power and the preset charging power;

[0093] The power generation device is controlled to charge the energy storage device according to the first excess power generation.

[0094] In order not to affect the normal charging of the device to be charged, the power generation equipment can only charge the power supply equipment when the power generation power is greater than the preset charging power. Moreover, when charging the device to be charged and the power supply equipment at the same time, the needs of the device to be charged need to be met first.

[0095] For example, the power generation capacity of the power generation equipment is 1000W, and the preset charging power of the device to be charged is 800W. If the energy storage device is also in the state to be charged, the power generation equipment can only charge the energy storage device with a power of 200W exceeding the preset charging power after first satisfying the demand of the device to be charged.

[0096] In one implementation, the power supply device further includes a power grid device, and the controlling the power generation device to charge the power supply device further includes:

[0097] Obtaining a target charging power of the energy storage device, and determining whether the first excess power generation power is greater than the target charging power;

[0098] If it is greater than, obtaining a second excess power generation power according to the first excess power generation power and the target charging power;

[0099] The power generation equipment is controlled to supply power to the power grid equipment according to the second excess power generation power.

[0100] If there is still power left after the power generation equipment charges both the device to be charged and the energy storage device, the remaining power can be provided to the grid equipment.

[0101] For example, the power generation power of the power generation equipment is 1500W, the preset charging power of the device to be charged is 800W, and the target charging power of the energy storage device is 400W. After the power generation equipment charges the device to be charged and the energy storage device at the same time, there is still 300W of remaining power, which can be provided to the power grid equipment.

[0102] In some cases, if there is no device to be charged or the energy storage device is already fully charged, the excess power of the power generation equipment can be delivered to the grid equipment.

[0103] In one implementation, before controlling the power generation equipment to supply power to the power grid equipment according to the second excess power generation, the method includes:

[0104] Determining whether the power grid equipment is equipped with a backflow prevention device;

[0105] If the anti-backflow device is provided, the second excess power generation of the power generation equipment is adjusted to a preset power range.

[0106] As an important protective device in the power system, the main function of the anti-backflow device is to prevent the occurrence of power backflow, thereby ensuring the stable operation of the power grid. Therefore, if the power grid equipment is equipped with an anti-backflow device, the power generation equipment cannot supply power to the power grid equipment. In order to avoid energy waste, while ensuring that the power generation equipment can charge all the devices to be charged and the energy storage equipment normally, the excess second excess power generation power is adjusted to a preset power range, which can be zero.

[0107] For example, the power generation capacity of the power generation equipment is 1500W, the preset charging power of the device to be charged is 800W, and the target charging power of the energy storage device is 400W. After the power generation equipment charges the device to be charged and the energy storage device at the same time, there is still 300W of remaining power, but the remaining power cannot be provided to the power grid equipment. At this time, the power generation capacity of the power generation equipment can be adjusted to about 1200W, so that it can just meet the charging needs of the device to be charged and the energy storage device, and avoid backflow.

[0108] Example 2

[0109] See also Figure 5 The present application also provides a power supply control system 500, including:

[0110] The power supply module 501 is used to determine whether the power generation power of the power generation device is greater than the preset charging power of the device to be charged when the power generation device is charging the device to be charged, and if the power generation power is less than or equal to the preset charging power, control the power supply device to supply power to the device to be charged;

[0111] A judgment module 502 is used to obtain the power supply power of the power supply device, obtain the total charging power according to the generated power and the power supply power, and judge whether the total charging power is greater than the preset charging power;

[0112] The adjustment module 503 is configured to adjust the preset charging power to a first charging power if the total charging power is less than or equal to the preset charging power, wherein the first charging power is less than or equal to the total charging power.
