[0002] The number of electric vehicles on the road is gradually increasing, leading to a greater demand for photovoltaic (PV) and energy storage charging systems. In related technologies, PV-energy storage systems can generally only provide a relatively low, fixed charging power for electric vehicles, or charge them within a specified time period. However, due to the randomness and volatility of PV power generation, the actual charging power provided to electric vehicles cannot meet user needs. Summary of the Invention

[0004] Another object of the present invention is to provide a power regulation device.

[0005] Another object of the present invention is to provide a power regulation system.

[0006] Another object of the present invention is to provide a readable storage medium.

[0007] Another object of the present invention is to provide a chip.

[0008] To achieve the above objectives, a first aspect of the present invention provides a power regulation method for a power regulation system. The power regulation system includes a controller, a charging pile electrically connected to the controller, at least one first electrical device, an energy storage battery, and a photovoltaic power generation device. The power regulation method includes: acquiring the operating mode of the charging pile; determining a first operating parameter of the charging pile, a second operating parameter of the photovoltaic power generation device, and a fourth operating parameter of the energy storage battery based on the operating mode; determining a power allocation corresponding to the charging pile based on at least one of the second operating parameter, a third operating parameter of the first electrical device, and the fourth operating parameter; and controlling the charging pile to charge external devices based on the power allocation.

[0009] According to the power regulation method provided by the present invention, the charging power of the charging pile can be dynamically adjusted in real time to maximize the power generation of the power regulation system and avoid dependence on the grid power, thereby improving energy utilization efficiency and reducing charging costs.

[0010] Specifically, this solution is mainly used in a power regulation system comprising a controller, charging piles, primary electrical devices, energy storage batteries, and photovoltaic power generation equipment. The controller is electrically connected to the charging piles, primary electrical devices, energy storage batteries, and photovoltaic power generation equipment. Under the controller's control, it can collect the real-time operating status and parameters of all devices and calculate the dynamic power available for allocation to the charging piles. The photovoltaic power generation equipment converts the direct current generated by photovoltaic power into alternating current and provides it to the system. The energy storage battery stores excess photovoltaic power and releases it when needed. Furthermore, one or more primary electrical devices can monitor the power consumption of commonly used household appliances, thereby helping the controller determine whether to draw power from the mains and ensuring stable system operation. By receiving the dynamic power calculated by the controller, efficient charging is achieved, reducing charging time.

[0011] By acquiring the charging station's operating mode, including whether the charging station is charging or whether it restricts the use of mains power, the system can understand the current charging demand and the charging station's operating capacity, thus providing basic data for subsequent power adjustment.

[0012] The system then determines the first operating parameters of the charging pile, the second operating parameters of the photovoltaic power generation equipment, and the fourth operating parameters of the energy storage battery based on the operating mode. Specifically, the system acquires and determines the operating parameters of each device according to the charging pile's operating mode. This may include the charging pile's maximum and minimum power, the photovoltaic power generation equipment's output power, and the energy storage battery's charging status and remaining capacity. These parameters will determine the subsequent power allocation strategy to ensure stable system operation and charging efficiency. The system will query information such as the operating status, output power, and battery capacity of the photovoltaic power generation equipment and energy storage battery based on the charging pile's needs. This allows the system to determine how much green energy can be provided for charging at any given time.

[0013] Then, based on one or more of the second operating parameters, the third operating parameters, and the fourth operating parameters of the first electrical device, the system determines the power allocation corresponding to the charging pile. Using the previously obtained operating parameters of the photovoltaic power generation equipment and energy storage battery, as well as the power demand of the first electrical device (such as a household appliance), the system calculates an appropriate power allocation to the charging pile. This process is dynamic; the system intelligently adjusts the charging power of the charging pile based on real-time power generation and consumption.

[0014] In simple terms, if the available power is within the charging station's operating range, it will be used directly. If the available power exceeds the charging station's maximum power, the charging station's maximum power will be used. If the available power is insufficient, the system will attempt to draw power from the energy storage battery and recalculate the available power. If the minimum charging requirement cannot be met even after drawing power from the energy storage battery, the system will temporarily stop charging and wait for conditions to improve.

[0015] Ultimately, the system controls the charging piles to charge external devices based on the allocated power. The system transmits the calculated optimal power to the charging piles, which then adjust their charging power accordingly. This ensures that the charging process always uses the optimal power, meeting user needs while maximizing the use of green energy. In essence, regardless of changes in the power generation of photovoltaic equipment, the charge level of energy storage batteries, or the electricity demand of household appliances, the system can adjust in real time to maintain the charging pile's charging power at its optimal level, thereby improving charging efficiency and reducing charging time.

[0016] In addition, the technical solution provided by the present invention may also have the following additional technical features:

[0017] In the above technical solution, the second operating parameter includes the photovoltaic power corresponding to the photovoltaic power generation equipment, the third operating parameter includes the power consumption, and the fourth operating parameter includes the charging power and discharging power corresponding to the energy storage battery.

[0018] The power allocation corresponding to the charging pile is determined based on at least one of the second operating parameters, the third operating parameters, and the fourth operating parameters of the first electrical device. Specifically, this includes: determining the power allocation corresponding to the charging pile based on the photovoltaic power and the power consumption when the energy storage battery is neither charging nor discharging and the photovoltaic power generation equipment is supplying power; or determining the power allocation corresponding to the charging pile based on the photovoltaic power, the charging power, and the power consumption when the energy storage battery is charging and the photovoltaic power generation equipment is supplying power; or determining the power allocation corresponding to the charging pile based on the photovoltaic power, the discharging power, and the power consumption when the energy storage battery is discharging and the photovoltaic power generation equipment is supplying power.

[0019] In this technical solution, the second operating parameter includes photovoltaic power, which is the electrical power currently generated by the photovoltaic power generation equipment. It represents the green energy available to the entire system, and the level of photovoltaic power directly affects the electrical power that the system can allocate to the charging piles. The third operating parameter includes power consumption, which represents the current power demand of the primary electrical device (such as a household appliance). The fourth operating parameter includes the charging and discharging power of the energy storage battery. The charging and discharging power determine whether the energy storage battery is currently providing power to the system or absorbing power from the system. When calculating the power allocated to the charging piles, the specific charging and discharging of the energy storage battery will correspond to different calculation methods.

[0020] The determination of power allocation is mainly based on the specific operating modes of the energy storage battery and photovoltaic power generation equipment. Specifically, in the mode where the energy storage battery is neither charged nor discharged, and the photovoltaic power generation equipment supplies power, the system mainly relies on the real-time power generation of the photovoltaic power generation equipment to determine the power that can be allocated to the charging pile. The system will calculate a suitable power value based on the photovoltaic power and the power consumption to ensure that the electricity demand of households or commercial facilities is met, while charging electric vehicles as much as possible.

[0021] Alternatively, in the mode of charging the energy storage battery and supplying power to the photovoltaic power generation equipment, the system needs to consider the additional charging power demand while the energy storage battery is charging. The system will calculate the power allocated to the charging pile based on the photovoltaic power, charging power, and power consumption to ensure that the charging demand of the charging pile and the power consumption demand of the primary electrical equipment are met at the same time as the charging demand of the energy storage battery.

[0022] Alternatively, there's the mode where the energy storage battery discharges while the photovoltaic power generation equipment supplies power. In this mode, the energy storage battery provides additional electrical energy to the system, increasing its power supply capacity. The system determines the power allocated to the charging pile based on the photovoltaic power, discharge power, and power consumption, using the energy from the energy storage battery to supplement the insufficient photovoltaic power generation, ensuring that the charging pile receives enough electrical energy for charging.

[0023] In other words, in the mode where the energy storage battery does not supply power and the photovoltaic power generation equipment supplies power, the energy storage battery does not participate in power supply. Therefore, it is only necessary to determine the allocated power corresponding to the charging pile based on the photovoltaic power and the power consumption, giving priority to the use of photovoltaic power generation and reducing dependence on the grid power. The allocated power = photovoltaic power - power consumption + real-time power of the charging pile.

[0024] In the mode where the energy storage battery is discharging and the photovoltaic power generation equipment is supplying power, the allocated power corresponding to the charging pile needs to be determined based on the photovoltaic power, the charging and discharging power of the energy storage battery, and the power consumption. The allocated power = photovoltaic power - power consumption + discharging power + real-time power of the charging pile. This comprehensively utilizes the power generated by photovoltaic power generation and the energy storage battery to improve system efficiency and green energy utilization. Specifically, when the energy storage battery is charging, the allocated power calculation is: allocated power = photovoltaic power - power consumption - charging power + real-time power of the charging pile.

[0025] It should be noted that the allocated power is not the same as the real-time power of the charging pile. The allocated power is determined based on at least one of the photovoltaic power, power consumption, charging and discharging power and the current power of the charging pile. During the dynamic adjustment of the allocated power, the allocated power calculated in the previous cycle can be used as the real-time power of the charging pile when calculating the allocated power in the next cycle, that is, there is a self-updating calculation process.

[0026] Among them, the power consumption can be obtained through the electricity meter installed in the home. By monitoring and obtaining the real-time power output of the power grid, the system can be provided with the current power supply status of the power grid, which serves as an important basis for power allocation decisions.

[0027] The power consumption is the real-time power output monitored by the power grid meter, reflecting the power consumption of the grid-side load. This information is used to determine how much power can be allocated to the charging pile. The power consumption includes the real-time power of the charging pile; therefore, when calculating the allocated power, the current real-time power of the charging pile must be taken into account. In other words, the allocated power is the power to be allocated to the charging pile, while the real-time power of the charging pile is its current power.

[0028] In the above technical solution, the first working parameter includes the charging power limit range, which determines the allocated power corresponding to the charging pile. Specifically, if the allocated power is greater than the upper limit of the charging power limit range, the upper limit is used as the adjusted allocated power; if the allocated power is less than the lower limit of the charging power limit range, the power is further allocated according to the charging and discharging setting parameters corresponding to the energy storage battery in the fourth working parameter, and the allocated power is determined based on the power further allocated; if the allocated power is within the charging power limit range, the allocated power is maintained.

[0029] In this technical solution, the first operating parameter includes the charging power limit range. When determining the allocated power, the calculation is primarily based on the charging power limit range, thereby ensuring the charging pile can operate safely and efficiently under any circumstances. This method guarantees that the charging pile will not receive power exceeding its design limits, and that it can obtain additional power from the energy storage battery when power is insufficient to meet charging needs. Specifically, it determines whether the allocated power exceeds the charging power limit range, ensuring that the power received by the charging pile does not exceed its maximum design capacity, thus preventing damage to the charging pile or connected electric vehicles due to excessive power.

[0030] If the allocated power exceeds the upper limit, the allocated power will be set to the maximum power limit of the charging pile, i.e., the upper limit, to prevent the charging pile from receiving power exceeding its safety threshold, ensuring that the charging pile operates within a safe range and avoiding overload.

[0031] If the allocated power is less than the lower limit, the charging and discharging settings of the energy storage battery will be obtained, including the current charge level, maximum discharge power, and battery health status of the energy storage battery. Then, the power to be allocated within the allowable range of the energy storage battery will be calculated, and the allocated power to the charging pile will be determined based on the power to be allocated. At this time, it may be necessary to control the discharge of the energy storage battery so that the total power supply can meet the minimum power requirements of the charging pile, and ensure that the charging pile can obtain the necessary power from the energy storage battery even when the photovoltaic power generation is insufficient to meet the demand.

[0032] It's understandable that if the allocated power is too low, the system will attempt to recalculate a dynamic power value that is greater than the lower limit but less than the upper limit within the allowable control range of the energy storage battery; this is known as power redistribution. If the allocated power is within the limits, the calculated allocated power can be used directly without additional adjustments.

[0033] In the above technical solution, the power distribution is determined according to the charging and discharging setting parameters corresponding to the energy storage battery in the fourth working parameters. Specifically, this includes: determining the charging power of the energy storage battery when it is in a charging state; and determining the power distribution when the energy storage battery is in a non-charging state based on the charging power and the power distribution.

[0034] In this technical solution, the fourth operating parameter involves the charging and discharging settings of the energy storage battery. This is achieved by determining the charging power of the energy storage battery in its charging state, which is the rate at which the battery currently absorbs electrical energy from the photovoltaic power generation equipment or the grid. Determining the charging power requires considering the current state of the energy storage battery, including its capacity, maximum charging rate, and battery health. During the charging state, the system needs to balance the charging power and the allocated power.

[0035] First, the charging power of the energy storage battery is subtracted from the allocated power to obtain the remaining power available for the charging station. Then, based on the maximum and minimum charging power limits of the charging station, the remaining power is adjusted to ensure that the charging demand of the charging station is met without exceeding its power limits.

[0036] Based on this, if it is found that the allocated power is still less than the minimum charging power, the re-allocation power in the state where the energy storage battery is not charging will be re-determined. In this scheme, the calculation of re-allocation power can be understood as calculating the power consumed by the energy storage battery during charging into the power allocated to the charging pile. That is, the re-allocation power is the power allocated to the charging pile when the energy storage battery is not charging. At this time, the calculation of re-allocation power is simpler, mainly to ensure that the power demand of the charging pile does not exceed its maximum charging power limit.

[0037] In the above technical solution, optionally, the allocation power is determined based on the re-division power, specifically including: if the re-division power is greater than or equal to the lower limit, then the lower limit is used as the adjusted allocation power; or if the re-division power is within the charging power limit range, then the re-division power is used as the adjusted allocation power; if the re-division power is greater than the upper limit, then the upper limit is used as the adjusted allocation power; if the re-division power is less than the lower limit, then the allocation power is 0.

[0038] In this technical solution, when determining the allocated power based on the previously determined re-division power, the main process involves comparing the re-division power with the charging power limit range. If the re-division power is greater than or equal to the lower limit of the charging pile's power, the system will use the lower limit as the adjusted allocated power. This means that even if the re-division power is high, the charging pile will charge with the minimum power requirement to avoid excessive energy consumption. Excess energy will continue to be allocated to the energy storage battery for charging, and can also be supplied to other primary electrical devices. If the re-division power is within the charging pile's charging power limit range (i.e., between the lower and upper limits), the system will use the re-division power as the adjusted allocated power. This ensures that the charging pile charges with the actual available power while not exceeding its power limit. If the re-division power exceeds the charging pile's upper power limit, the system will use the upper limit as the adjusted allocated power. This prevents potential damage or efficiency reduction to the charging pile due to excessive power.

[0039] If the allocated power is less than the charging station's minimum power limit, the system will set the allocated power to 0. In this case, the charging station will not charge to avoid an ineffective or inefficient charging process.

[0040] In the above technical solution, the power distribution is determined according to the charging and discharging setting parameters corresponding to the energy storage battery in the fourth working parameters. Specifically, this includes: determining the real-time battery capacity of the energy storage battery; determining the maximum discharge power of the energy storage battery when the real-time battery capacity is greater than the minimum capacity limit; and determining the power distribution when the energy storage battery is in a discharging state based on the maximum discharge power and the power distribution.

[0041] In this technical solution, when determining the power distribution based on the charging and discharging settings, the current battery charge level, i.e., the real-time battery charge level, is also taken into account. The battery will only be allowed to discharge if the real-time battery charge level exceeds the minimum charge limit of the battery, in order to meet the power demand of the charging pile. Specifically, the system sets a minimum charge limit to ensure that the battery still has enough charge to maintain basic backup needs after discharge, avoiding over-discharge that could affect battery life.

[0042] If the real-time charge level of the energy storage battery is greater than or equal to the minimum charge limit, the battery is deemed to meet the discharge conditions and can proceed with the discharge operation. After confirming sufficient charge, the system determines its maximum discharge power based on the battery's specifications and current state. This parameter represents the maximum electrical power the battery can safely provide during discharge. The system calculates the additional power allocation based on the battery's maximum discharge power and the power currently allocated to the charging station. If the allocated power is insufficient to meet the charging station's needs, the system will consider using the battery's discharge capacity to supplement it. If the battery discharge provides sufficient power to ensure the charging station's total power meets or exceeds its requirements, the additional power allocation will equal the charging station's required power. If the battery discharge power plus the allocated power is still lower than the charging station's requirements, the additional power allocation will equal the battery's maximum discharge power plus the allocated power.

[0043] Based on the calculated power distribution, the system will adjust the discharge power of the energy storage battery and the charging power of the charging pile to ensure that the charging pile can obtain the required power.

[0044] In the above technical solution, the allocation power is determined based on the re-division power, specifically including: if the re-division power is less than the lower limit, the allocation power is 0; if the re-division power is within the charging power limit range, the allocation power is the re-division power; if the re-division power is greater than the upper limit, the discharge power of the energy storage battery is reduced, and the upper limit is used as the adjusted allocation power.

[0045] In this technical solution, when determining the allocation power based on the re-division power, the re-division power is calculated based on the maximum discharge power of the energy storage battery. Therefore, if the re-division power cannot meet the lower limit, it is considered that power cannot be supplied to the charging pile, and the allocation power is set to 0. When the re-division power is within the charging power limit range or greater than the upper limit, it is considered that power can be supplied to the charging pile. Specifically, if it is within the charging power limit range, the recalculated re-division power is directly allocated to the charging pile for charging. If the re-division power is greater than the upper limit, the upper limit is used to allocate power to the charging pile for charging.

[0046] It is understandable that checking whether the power after adjustment by the energy storage battery is still lower than the minimum power required by the charging station is necessary to ensure that charging will not proceed when the energy storage battery cannot provide sufficient power, thus protecting the charging station and the electric vehicle.

[0047] In the above technical solution, determining the allocated power corresponding to the charging pile specifically includes: continuously determining the allocated power at intervals of a first cycle; wherein the first cycle is no more than 5 seconds.

[0048] This technical solution ensures the continuous operation of the charging pile while meeting charging rules by periodically checking and adjusting the allocated power, while maintaining real-time monitoring and adjustment of power distribution. This periodic adjustment mechanism improves the system's response speed and flexibility, ensuring the continuity and stability of the charging process. Specifically, the compliance of charging rules can be periodically checked to ensure that the charging pile conforms to the charging rules in each cycle. Through regular checks, the operating status of the charging pile is ensured to always meet safety and efficiency requirements.

[0049] The system dynamically adjusts power allocation based on real-time data during each cycle to maintain the charging pile's charging power at its optimal level, responding to changes in photovoltaic power generation and grid conditions. Power allocation ceases when any operating parameter fails to meet the charging pile's charging rules, preventing unsafe or inefficient charging, protecting the charging pile and electric vehicle, and preventing charging under adverse conditions.

[0050] The interval for acquiring allocated power is the first cycle, with a specific value of less than or equal to 5 seconds, to ensure that the system can quickly respond to changes in power demand.

[0051] This solution enables periodic checks, allowing the system to quickly respond to changes in external conditions and ensure continuous charging when conditions are met. Through regular adjustments, the stability and reliability of the charging process are maintained. This periodic power regulation method allows the power regulation system to manage power resources more intelligently, providing users with a safe and efficient charging environment while ensuring the continuity and stability of the charging process.

[0052] A second aspect of the present invention provides a power regulation device for a power regulation system. The power regulation system includes a controller, a charging pile electrically connected to the controller, at least one first electrical device, an energy storage battery, and a photovoltaic power generation device. The power regulation device includes: a charging pile parameter determination module for acquiring the operating mode of the charging pile; a power supply parameter determination module for determining a first operating parameter of the charging pile, a second operating parameter of the photovoltaic power generation device, and a fourth operating parameter of the energy storage battery according to the operating mode; a power allocation module for determining the allocated power corresponding to the charging pile according to at least one of the second operating parameter, a third operating parameter of the first electrical device, and the fourth operating parameter; and a charging module for controlling the charging pile to charge external devices according to the allocated power.

[0053] According to the technical solution of the power regulation device of the present invention, it mainly includes a charging pile parameter determination module, a power supply parameter determination module, a power distribution module and a charging module. It can maximize the use of the power regulation system for power generation by dynamically adjusting the charging power of the charging pile in real time, and avoid dependence on the grid power, thereby improving energy utilization efficiency and reducing charging costs.

[0054] Specifically, this solution is mainly used in a power regulation system comprising a controller, charging piles, primary electrical devices, energy storage batteries, and photovoltaic power generation equipment. The controller is electrically connected to the charging piles, primary electrical devices, energy storage batteries, and photovoltaic power generation equipment. Under the controller's control, it can collect the real-time operating status and parameters of all devices and calculate the dynamic power available for allocation to the charging piles. The photovoltaic power generation equipment converts the direct current generated by photovoltaic power into alternating current and provides it to the system. The energy storage battery stores excess photovoltaic power and releases it when needed. Furthermore, one or more primary electrical devices can monitor the power consumption of commonly used household appliances, thereby helping the controller determine whether to draw power from the mains and ensuring stable system operation. By receiving the dynamic power calculated by the controller, efficient charging is achieved, reducing charging time.

[0055] By acquiring the charging station's operating mode, including whether the charging station is charging or whether it restricts the use of mains power, the system can understand the current charging demand and the charging station's operating capacity, thus providing basic data for subsequent power adjustment.

[0056] The system determines the first set of operating parameters for the charging pile, the second set for the photovoltaic power generation equipment, and the fourth set for the energy storage battery based on the charging pile's operating mode. Specifically, the system acquires and determines the operating parameters of each device according to the charging pile's operating mode. This may include the charging pile's maximum and minimum power, the photovoltaic power generation equipment's output power, and the energy storage battery's charging status and remaining capacity. These parameters will determine the subsequent power allocation strategy to ensure stable system operation and charging efficiency. The system will also query information such as the operating status, output power, and battery capacity of the photovoltaic power generation equipment and energy storage battery based on the charging pile's needs. This allows the system to determine how much green energy can be provided for charging at any given time.

[0057] Then, based on one or more of the second operating parameters, the third operating parameters, and the fourth operating parameters of the first electrical device, the system determines the power allocation corresponding to the charging pile. Using the previously obtained operating parameters of the photovoltaic power generation equipment and energy storage battery, as well as the power demand of the first electrical device (such as a household appliance), the system calculates an appropriate power allocation to the charging pile. This process is dynamic; the system intelligently adjusts the charging power of the charging pile based on real-time power generation and consumption.

[0058] Ultimately, the system controls the charging piles to charge external devices based on the allocated power. The system transmits the calculated optimal power to the charging piles, which then adjust their charging power accordingly. This ensures that the charging process always uses the optimal power, meeting user needs while maximizing the use of green energy. In essence, regardless of changes in the power generation of photovoltaic equipment, the charge level of energy storage batteries, or the electricity demand of household appliances, the system can adjust in real time to maintain the charging pile's charging power at its optimal level, thereby improving charging efficiency and reducing charging time.

[0059] A third aspect of the present invention provides a power regulation system, comprising: any of the power regulation devices described above; a controller; and a charging pile, at least one first electrical device, an energy storage battery, and a photovoltaic power generation device electrically connected to the controller, wherein the power regulation device includes the controller.

[0060] Another aspect of the present invention provides a power regulation system, including a processor, a memory, and a program or instructions stored in the memory and executable on the processor. When the program or instructions are executed by the processor, they implement the steps of the power regulation method in any of the above-described technical solutions.

[0061] A fourth aspect of the present invention provides a readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the power regulation method in any of the above-described technical solutions.

[0062] The fifth aspect of the present invention provides a chip, the chip including a processor and a communication interface, the communication interface and the processor being coupled, the processor being used to run a program or instructions to implement the steps of the power regulation method in any of the above technical solutions.

Detailed Implementation

[0078] To better understand the above-described objectives, features, and advantages of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0079] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, embodiments of the invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0080] The following reference Figures 1 to 12 This invention describes a power regulation method, a power regulation device, a power regulation system, a readable storage medium, and a chip provided according to some embodiments of the present invention.

[0081] This embodiment provides a power regulation method for a power regulation system. The power regulation system includes a controller, a charging pile electrically connected to the controller, at least one first electrical device, an energy storage battery, and a photovoltaic power generation device, such as... Figure 1 As shown, the power regulation method includes:

[0082] Step S102: Obtain the working mode of the charging pile;

[0083] Step S104: Determine the first operating parameters of the charging pile, the second operating parameters of the photovoltaic power generation equipment, and the fourth operating parameters of the energy storage battery according to the working mode;

[0084] Step S106: Determine the allocated power corresponding to the charging pile based on at least one of the second operating parameters, the third operating parameters and the fourth operating parameters of the first electrical equipment;

[0085] Step S108: Control the charging pile to charge external devices according to the allocated power.

[0086] The power regulation method provided in this embodiment can maximize the use of the power regulation system for power generation by dynamically adjusting the charging power of the charging pile in real time, and avoid dependence on the mains power grid, thereby improving energy utilization efficiency and reducing charging costs.

[0087] Specifically, this solution is mainly used in a power regulation system comprising a controller, charging piles, primary electrical devices, and power supply equipment. The controller is electrically connected to both the charging pile and the power supply equipment. Under the controller's control, it can collect the real-time operating status and parameters of all devices and calculate the dynamic power that can be allocated to the charging pile. The photovoltaic power generation equipment converts the direct current generated by photovoltaic power into alternating current and provides it to the system. The energy storage battery stores excess photovoltaic power and releases it when needed. Furthermore, one or more primary electrical devices can monitor the power consumption of commonly used household appliances, thereby helping the controller determine whether to draw power from the mains and ensuring stable system operation. By receiving the dynamic power calculated by the controller, efficient charging is achieved, reducing charging time.

[0088] Specifically, by acquiring the first operating parameters of the charging pile, including information such as the charging pile's operating status, operating mode, maximum / minimum charging power limits, and real-time charging power, the system can understand the current charging demand and the charging pile's operating capacity, thus providing basic data for subsequent power adjustment.

[0089] The system then determines the second operating parameters of the power supply equipment based on the first operating parameter. It then queries information such as the operating status, power generation, and battery capacity of the photovoltaic power generation equipment and energy storage battery according to the charging pile's needs. This determines how much green energy can be provided for charging. Based on the second operating parameter and / or the third operating parameter of the first power-consuming equipment, the system determines the allocated power corresponding to the charging pile. It comprehensively considers factors such as photovoltaic power generation, available energy storage battery capacity, and household electrical load to calculate the optimal power that can be allocated to the charging pile. This dynamic adjustment maximizes the utilization of renewable energy while avoiding impact on the power grid.

[0090] In simple terms, if the available power is within the charging station's operating range, it will be used directly. If the available power exceeds the charging station's maximum power, the charging station's maximum power will be used. If the available power is insufficient, the system will attempt to draw power from the energy storage battery and recalculate the available power. If the minimum charging requirement cannot be met even after drawing power from the energy storage battery, the system will temporarily stop charging and wait for conditions to improve.

[0091] Ultimately, the system controls the charging piles to charge external devices based on the allocated power. The system transmits the calculated optimal power to the charging piles, which then adjust their charging power accordingly. This ensures that the charging process always uses the optimal power, meeting user needs while maximizing the use of green energy.

[0092] Furthermore, high-frequency adjustments, such as every 5 seconds, ensure the system can quickly respond to various changes, promptly addressing fluctuations in photovoltaic power generation and variations in household electricity load, resulting in a smoother and more efficient charging process. Edge computing further enhances the system's real-time performance and reliability, reducing reliance on the cloud, lowering network latency and data transmission costs, and improving system response speed and stability. Of course, the controller in this solution can have various types of interfaces, such as RJ45 Ethernet ports and RS485 communication cables, improving system compatibility and scalability, allowing connection to various types of devices, making the system more flexible and adaptable.

[0093] It is understandable that the first, second, third, and fourth operating parameters can be used to determine whether the charging rules are met. Specific charging rules could include checking whether the charging pile and power supply equipment meet preset charging conditions, such as whether the photovoltaic power generation is sufficient and whether the energy storage battery is in a safe state. Furthermore, if the inverter cannot generate power normally, or its operating status is unknown and dynamic power cannot be calculated, then dynamic power cannot be allocated to the charging pile, meaning charging cannot proceed.

[0094] Optionally, such as Figure 2As shown, the power allocation corresponding to the charging pile is determined based on at least one of the second operating parameters, the third operating parameters, and the fourth operating parameters of the first electrical device, including:

[0095] Step S1062: In the mode where the energy storage battery is neither charging nor discharging, and the photovoltaic power generation equipment supplies power, determine the allocated power corresponding to the charging pile based on the photovoltaic power and the power consumption; or

[0096] Step S1064: When the energy storage battery is charging and the photovoltaic power generation equipment is supplying power, determine the allocated power corresponding to the charging pile based on the photovoltaic power, charging power, and power consumption; or

[0097] Step S1066: In the mode where the energy storage battery is discharging and the photovoltaic power generation equipment is supplying power, determine the allocated power corresponding to the charging pile based on the photovoltaic power, discharge power and power consumption.

[0098] In this embodiment, the second operating parameter includes photovoltaic power, which is the electrical power currently generated by the photovoltaic power generation equipment. It is a green energy source available to the entire system, and the level of photovoltaic power directly affects the electrical power that the system can allocate to the charging pile. The third operating parameter includes power consumption, which represents the current power demand of the first electrical device (such as a household appliance). The fourth operating parameter includes the charging power and discharging power of the energy storage battery. The charging power and discharging power determine whether the energy storage battery is currently providing electrical energy to the system or absorbing electrical energy from the system. When calculating the power allocated to the charging pile, the specific charging and discharging of the energy storage battery will correspond to different calculation methods.

[0099] The determination of power allocation is mainly based on the specific operating modes of the energy storage battery and photovoltaic power generation equipment. Specifically, in the mode where the energy storage battery is neither charged nor discharged, and the photovoltaic power generation equipment supplies power, the system mainly relies on the real-time power generation of the photovoltaic power generation equipment to determine the power that can be allocated to the charging pile. The system will calculate a suitable power value based on the photovoltaic power and the power consumption to ensure that the electricity demand of households or commercial facilities is met, while charging electric vehicles as much as possible.

[0100] Alternatively, in the mode of charging the energy storage battery and supplying power to the photovoltaic power generation equipment, the system needs to consider the additional charging power demand while the energy storage battery is charging. The system will calculate the power allocated to the charging pile based on the photovoltaic power, charging power, and power consumption to ensure that the charging demand of the charging pile and the power consumption demand of the primary electrical equipment are met at the same time as the charging demand of the energy storage battery.

[0101] Alternatively, there's the mode where the energy storage battery discharges while the photovoltaic power generation equipment supplies power. In this mode, the energy storage battery provides additional electrical energy to the system, increasing its power supply capacity. The system determines the power allocated to the charging pile based on the photovoltaic power, discharge power, and power consumption, using the energy from the energy storage battery to supplement the insufficient photovoltaic power generation, ensuring that the charging pile receives enough electrical energy for charging.

[0102] In other words, in the mode where the energy storage battery does not supply power and the photovoltaic power generation equipment supplies power, the energy storage battery does not participate in power supply. Therefore, it is only necessary to determine the allocated power corresponding to the charging pile based on the photovoltaic power and the power consumption, giving priority to the use of photovoltaic power generation and reducing dependence on the grid power. The allocated power = photovoltaic power - power consumption + real-time power of the charging pile.

[0103] In the mode where the energy storage battery is discharging and the photovoltaic power generation equipment is supplying power, the allocated power corresponding to the charging pile needs to be determined based on the photovoltaic power, the charging and discharging power of the energy storage battery, and the power consumption. The allocated power = photovoltaic power - power consumption + discharging power + real-time power of the charging pile. This comprehensively utilizes the power generated by photovoltaic power generation and the energy storage battery to improve system efficiency and green energy utilization. Specifically, when the energy storage battery is charging, the allocated power calculation is: allocated power = photovoltaic power - power consumption - charging power + real-time power of the charging pile.

[0104] It should be noted that the allocated power is not the same as the real-time power of the charging pile. The allocated power is determined based on at least one of the photovoltaic power, power consumption, charging and discharging power and the current power of the charging pile. During the dynamic adjustment of the allocated power, the allocated power calculated in the previous cycle can be used as the real-time power of the charging pile when calculating the allocated power in the next cycle, that is, there is a self-updating calculation process.

[0105] Among them, the power consumption can be obtained through the electricity meter installed in the home. By monitoring and obtaining the real-time power output of the power grid, the system can be provided with the current power supply status of the power grid, which serves as an important basis for power allocation decisions.

[0106] The power consumption is the real-time power output monitored by the power grid meter, reflecting the power consumption of the grid-side load. This information is used to determine how much power can be allocated to the charging pile. The power consumption includes the real-time power of the charging pile; therefore, when calculating the allocated power, the current real-time power of the charging pile must be taken into account. In other words, the allocated power is the power to be allocated to the charging pile, while the real-time power of the charging pile is its current power.

[0107] Furthermore, the second operating parameter includes the grid connection mode of the photovoltaic power generation equipment; when the photovoltaic power generation equipment is in grid-connected mode, the power consumption priority of the charging pile is higher than that of the first power consumption equipment; when the photovoltaic power generation equipment is in off-grid mode, the power consumption priority of the first power consumption equipment is higher than that of the charging pile.

[0108] The second set of operating parameters specifically includes grid-connected mode and off-grid mode. In grid-connected mode, the electricity generated by the photovoltaic power generation equipment can be directly transmitted to the grid. In this mode, the charging pile has a higher power priority than the first electrical device, ensuring that the charging pile can use the photovoltaic power generation first. In off-grid mode, the photovoltaic power generation equipment operates independently and is not connected to the grid. In this mode, the first electrical device has a higher power priority than the charging pile, ensuring the normal operation of critical electrical equipment. Only when the photovoltaic power generation equipment is in grid-connected mode, the power of the charging pile is dynamically adjusted according to at least one of the second, third, and fourth power parameters, i.e., the step of determining the allocated power corresponding to the charging pile is executed.

[0109] Optionally, such as Figure 3 As shown, determining the allocated power corresponding to the charging pile specifically includes: Step S1072: If the allocated power is greater than the upper limit of the charging power limit range, the upper limit is used as the adjusted allocated power; Step S1074: If the allocated power is less than the lower limit of the charging power limit range, the re-allocated power is determined according to the charging and discharging setting parameters corresponding to the energy storage battery in the fourth working parameters, and the allocated power is determined according to the re-allocated power; Step S1076: If the allocated power is within the charging power limit range, the allocated power is maintained.

[0110] In this embodiment, the first operating parameter includes a charging power limit range. When determining the allocated power, the calculation is primarily based on this charging power limit range, ensuring the charging pile operates safely and efficiently under all circumstances. This method guarantees that the charging pile will not receive power exceeding its design limits, and allows it to draw additional power from the energy storage battery when power is insufficient to meet charging needs. Specifically, it determines whether the allocated power exceeds the charging power limit range, ensuring that the power received by the charging pile does not exceed its maximum design capacity, thus preventing damage to the charging pile or connected electric vehicles due to excessive power.

[0111] If the allocated power exceeds the upper limit, the allocated power will be set to the maximum power limit of the charging pile, i.e., the upper limit, to prevent the charging pile from receiving power exceeding its safety threshold, ensuring that the charging pile operates within a safe range and avoiding overload.

[0112] If the allocated power is less than the lower limit, the charging and discharging settings of the energy storage battery will be obtained, including the current charge level, maximum discharge power, and battery health status of the energy storage battery. Then, the power to be allocated within the allowable range of the energy storage battery will be calculated, and the allocated power to the charging pile will be determined based on the power to be allocated. At this time, it may be necessary to control the discharge of the energy storage battery so that the total power supply can meet the minimum power requirements of the charging pile, and ensure that the charging pile can obtain the necessary power from the energy storage battery even when the photovoltaic power generation is insufficient to meet the demand.

[0113] It's understandable that if the allocated power is too low, the system will attempt to recalculate a dynamic power value that is greater than the lower limit but less than the upper limit within the allowable control range of the energy storage battery; this is known as power redistribution. If the allocated power is within the limits, the calculated allocated power can be used directly without additional adjustments.

[0114] The charging power limit range includes an upper and a lower limit. The upper limit is the maximum power that the charging pile can safely receive. The lower limit is the minimum power required for the charging pile to operate normally. For example, the upper limit is the rated power of the charging pile itself, which is adjusted according to different charging pile models, such as 7kW, 11kW, 21kW, etc., while the lower limit is the set power, which can be 1kW, 1.3kW, 1.36kW, etc.

[0115] In one embodiment, such as Figure 4 As shown, if the allocated power is less than the lower limit of the charging power limit range, the re-allocation power is determined according to the charging and discharging setting parameters corresponding to the energy storage battery in the fourth working parameters. The allocation power is determined based on the re-allocation power, specifically including: Step S10742: If the allocated power is less than the lower limit of the charging power limit range, the charging power of the energy storage battery is determined when the energy storage battery is in a charging state; Step S10744: The re-allocation power is determined when the energy storage battery is in a non-charging state based on the charging power and the allocated power; Step S10746: The allocation power is determined based on the re-allocation power.

[0116] The fourth operating parameter involves the charging and discharging settings of the energy storage battery. This is achieved by determining the charging power of the energy storage battery during its charging state; the charging power is the rate at which the energy storage battery absorbs electrical energy from the photovoltaic power generation equipment or the grid. Determining the charging power requires considering the current state of the energy storage battery, including its capacity, maximum charging rate, and battery health. During the energy storage battery charging state, the system needs to balance the charging power and the allocated power.

[0117] First, the charging power of the energy storage battery is subtracted from the allocated power to obtain the remaining power available for the charging station. Then, based on the maximum and minimum charging power limits of the charging station, the remaining power is adjusted to ensure that the charging demand of the charging station is met without exceeding its power limits.

[0118] Based on this, if it is found that the allocated power is still less than the minimum charging power, the re-allocation power in the state where the energy storage battery is not charging will be re-determined. In this scheme, the calculation of re-allocation power can be understood as calculating the power consumed by the energy storage battery during charging into the power allocated to the charging pile. That is, the re-allocation power is the power allocated to the charging pile when the energy storage battery is not charging. At this time, the calculation of re-allocation power is simpler, mainly to ensure that the power demand of the charging pile does not exceed its maximum charging power limit.

[0119] Furthermore, the allocation power is determined based on the re-division power, specifically including: if the re-division power is less than the lower limit, the allocation power is 0; if the re-division power is greater than or equal to the lower limit, the lower limit is used as the adjusted allocation power; or if the re-division power is within the charging power limit range, the re-division power is used as the adjusted allocation power; if the re-division power is greater than the upper limit, the upper limit is used as the adjusted allocation power.

[0120] When determining the allocated power based on the previously determined redistribution power, the system primarily compares the redistribution power with the charging power limit range. If the redistribution power is greater than or equal to the lower limit of the charging pile's power, the system uses the lower limit as the adjusted allocated power. This means that even if the redistribution power is high, the charging pile will charge at the minimum power requirement to avoid excessive energy consumption. Excess energy continues to be allocated to the energy storage battery for charging, and can also be supplied to other primary electrical devices. If the redistribution power is within the charging pile's charging power limit range (i.e., between the lower and upper limits), the system uses the redistribution power as the adjusted allocated power. This ensures that the charging pile charges at the actual available power without exceeding its power limit. If the redistribution power exceeds the charging pile's upper power limit, the system uses the upper limit as the adjusted allocated power. This prevents potential damage or efficiency reduction to the charging pile due to excessive power.

[0121] If the allocated power is less than the charging station's minimum power limit, the system will set the allocated power to 0. In this case, the charging station will not charge to avoid an ineffective or inefficient charging process.

[0122] In another embodiment, such as Figure 5As shown, if the allocated power is less than the lower limit of the charging power limit, the re-allocation power is determined according to the charging and discharging setting parameters corresponding to the energy storage battery in the fourth working parameters. The allocation power is determined based on the re-allocation power, specifically including: Step S10743: If the allocated power is less than the lower limit of the charging power limit, the real-time battery capacity of the energy storage battery is determined; Step S10745: If the real-time battery capacity is greater than the minimum capacity limit, the maximum discharge power of the energy storage battery is determined; Step S10747: Based on the maximum discharge power and the allocated power, the re-allocation power is determined when the energy storage battery is in a discharging state.

[0123] When determining the redistribution power based on the charging and discharging settings, the current battery charge level, i.e., the real-time battery charge level, can also be considered. The battery will only be allowed to discharge if the real-time battery charge level is greater than the minimum charge limit of the battery, in order to meet the power demand of the charging pile. Specifically, the system sets a minimum charge limit to ensure that the battery still has enough charge to maintain basic backup needs after discharge, avoiding over-discharge that could affect battery life.

[0124] If the real-time charge level of the energy storage battery is greater than or equal to the minimum charge limit, the battery is deemed to meet the discharge conditions and can proceed with the discharge operation. After confirming sufficient charge, the system determines its maximum discharge power based on the battery's specifications and current state. This parameter represents the maximum electrical power the battery can safely provide during discharge. The system calculates the additional power allocation based on the battery's maximum discharge power and the power currently allocated to the charging station. If the allocated power is insufficient to meet the charging station's needs, the system will consider using the battery's discharge capacity to supplement it. If the battery discharge provides sufficient power to ensure the charging station's total power meets or exceeds its requirements, the additional power allocation will equal the charging station's required power. If the battery discharge power plus the allocated power is still lower than the charging station's requirements, the additional power allocation will equal the battery's maximum discharge power plus the allocated power.

[0125] Based on the calculated power distribution, the system will adjust the discharge power of the energy storage battery and the charging power of the charging pile to ensure that the charging pile can obtain the required power.

[0126] Optionally, such as Figure 6 As shown, if the allocated power is less than the lower limit of the charging power limit, the further allocated power is determined according to the charging and discharging setting parameters corresponding to the energy storage battery in the fourth operating parameter. Determining the allocated power based on the further allocated power includes:

[0127] Step S1102: If the allocated power is less than the lower limit of the charging power limit, then determine the further allocated power according to the charging and discharging setting parameters corresponding to the energy storage battery in the fourth working parameters;

[0128] Step S1104: If the power distribution is less than the lower limit, then the power distribution is 0;

[0129] Step S1106: If the power distribution is within the charging power limit range, then the power distribution is the power distribution.

[0130] Step S1108: If the power distribution is greater than the upper limit, the upper limit is used as the adjusted power distribution.

[0131] In this embodiment, when determining the allocation power based on the re-division power, the re-division power is calculated based on the maximum discharge power of the energy storage battery. Therefore, if the re-division power cannot meet the lower limit, it is considered that power cannot be supplied to the charging pile, and the allocation power is set to 0. When the re-division power is within the charging power limit range or greater than the upper limit, it is considered that power can be supplied to the charging pile. Specifically, if it is within the charging power limit range, the recalculated re-division power is directly allocated to the charging pile for charging. If the re-division power is greater than the upper limit, the upper limit is used to allocate power to the charging pile for charging.

[0132] It is understandable that checking whether the power after adjustment by the energy storage battery is still lower than the minimum power required by the charging station is necessary to ensure that charging will not proceed when the energy storage battery cannot provide sufficient power, thus protecting the charging station and the electric vehicle.

[0133] Furthermore, by setting up periodic checks and adjustments to the allocated power, this method ensures that the charging pile operates continuously while meeting charging rules, and maintains real-time monitoring and adjustment of power allocation. This periodic adjustment mechanism improves the system's response speed and flexibility, ensuring the continuity and stability of the charging process. Specifically, the compliance of charging rules can be checked periodically to ensure that the charging pile conforms to the charging rules in each cycle. Through regular checks, the operating status of the charging pile is ensured to always meet safety and efficiency requirements.

[0134] The system dynamically adjusts power allocation based on real-time data during each cycle to maintain the charging pile's charging power at its optimal level, responding to changes in photovoltaic power generation and grid conditions. Power allocation ceases when any operating parameter fails to meet the charging pile's charging rules, preventing unsafe or inefficient charging, protecting the charging pile and electric vehicle, and preventing charging under adverse conditions.

[0135] The interval for acquiring allocated power is the first cycle, with a specific value of less than or equal to 5 seconds, to ensure that the system can quickly respond to changes in power demand.

[0136] This solution enables periodic checks, allowing the system to quickly respond to changes in external conditions and ensure continuous charging when conditions are met. Through regular adjustments, the stability and reliability of the charging process are maintained. This periodic power regulation method allows the power regulation system to manage power resources more intelligently, providing users with a safe and efficient charging environment while ensuring the continuity and stability of the charging process.

[0137] In one specific embodiment, a method for adjusting the power of charging piles in a photovoltaic (PV) energy storage system is proposed. First, the user sets the operating mode of the charging pile and acquires uplink data from the charging pile, including its operating status, operating mode, maximum charging power, minimum charging power, real-time charging power, and maximum allowable power purchase. The acquisition period for this data is 1 second. When the charging pile is determined to be activated, different power adjustments are made based on different operating modes. Wherein, PV represents PV power generation, Pload represents load power (including the real-time power of the charging pile), Pev represents the real-time power of the charging pile, Pevmax represents the maximum charging power of the charging pile (typically the rated power), Pevmin represents the minimum charging power of the charging pile (typically a fixed value, such as 1.36 kW), Pbc represents the real-time charging power of the battery, Pbd represents the real-time discharging power of the battery, Pbdmax represents the maximum discharging power of the battery, and Pgm represents the maximum allowable power purchase.

[0138] Specifically, such as Figure 10As shown, when the operating mode is photovoltaic power supply, the uplink data of the integrated household energy storage unit is acquired, including operating status, operating mode, photovoltaic power generation, load power, battery operating status, battery power, maximum battery discharge power, charging power limit, and discharge power limit. The acquisition period for the above data is 1 second. When the photovoltaic is in grid-connected mode, the dynamic charging power A is initially calculated, and then it is determined whether A is less than the minimum charging power. If A is less than the minimum charging power, then when the battery is charging, the dynamic charging power B corresponding to the charging pile is calculated. If B is not less than the minimum charging power, the charging power limit is adjusted, specifically adjusted to PV-Pload+Pev-Pevmin+Pgm, and then... By acquiring the uplink data from the integrated home charging station, the dynamic charging power C is calculated. If C is greater than the maximum charging power, the dynamic power is issued at the maximum power of the charging station; otherwise, the dynamic power is determined based on the battery's control state. Specifically, if the battery is not controlled, dynamic power A is issued; if the battery is controlled, dynamic power B is issued. This continues until charging is completed, at which point the charging limit for the battery is restored. If A is not less than the minimum charging power, the dynamic power is issued at the maximum power of the charging station if A is greater than the maximum charging power; otherwise, the dynamic power is determined based on the battery's control state. Specifically, if the battery is not controlled, dynamic power A is issued; if the battery is controlled, dynamic power B is issued. This continues until charging is completed, at which point the charging limit for the battery is restored.

[0139] Among them, A=PV-Pload-Pbc+Pev+Pgm, B=PV-Pload+Pev+Pgm, C=PV-Pload-Pbc+Pev+Pgm.

[0140] In a specific embodiment, such as Figure 11 As shown, a method for adjusting the charging pile power of a photovoltaic (PV) household energy storage system is proposed. In the working mode of PV + battery combined power supply, the uplink data of the integrated household energy storage unit is first acquired. With the PV system in grid-connected mode, the dynamic charging power D is calculated. If D is less than the minimum charging power, the dynamic charging power E corresponding to the battery being charged is determined. If E is less than the minimum charging power, and the ratio of the battery's remaining capacity to its rated capacity (i.e., State of Charge) is greater than the minimum SOC, the dynamic charging power F is calculated. If F is not less than the minimum charging power, the battery is controlled to discharge at its maximum discharge power. If the dynamic power is greater than the maximum charging power at this point, the dynamic power is issued at the charging pile's maximum power. If the dynamic power is not greater than the maximum charging power at this point, the dynamic power F is issued until charging is complete. When E is not less than the minimum charging power, the battery charging power is adjusted.

[0141] The specific battery charging power is adjusted to PV-Pload + Pev-Pevmin + Pgm, and uplink data from the integrated home storage unit is acquired. Simultaneously, the dynamic charging power G is calculated. If G is greater than the maximum charging power, the dynamic power is issued at the maximum power of the charging pile. If G is not greater than the maximum charging power, the dynamic power G is issued until charging is complete, at which point the battery charging limit is restored. If D is not less than the minimum charging power, and D is greater than the maximum charging power, the dynamic power is issued at the maximum power of the charging pile; otherwise, the dynamic power D is issued directly.

[0142] Among them, D=PV-Pload-Pbc+Pev+Pgm, E=PV-Pload+Pev+Pgm, F=PV-Pload+Pev+Pbdmax+Pgm, G=PV-Pload-Pbc+Pev+Pgm.

[0143] In a specific embodiment, such as Figure 12 As shown, a method for adjusting the power of charging piles in a photovoltaic (PV) and energy storage system is proposed. In the case of combined PV and battery power supply, the uplink data of the integrated energy storage unit is first acquired. With the PV system in grid-connected mode, the dynamic charging power D is calculated. If D is less than the minimum charging power, and the battery is not currently charging, the dynamic charging power H is calculated. If H is less than the minimum charging power, and the battery's state of charge (SOC) is greater than the minimum SOC, the dynamic charging power J is calculated. If J is not less than the minimum charging power, the battery is controlled to discharge at its maximum discharge power. If the dynamic power is greater than the maximum charging power at this point, the dynamic power is issued at the maximum power of the charging pile. If the dynamic power is not greater than the maximum charging power, the dynamic power J is issued until charging is completed, at which point the integrated energy storage unit returns to its original operating mode. If H is not less than the minimum charging power, and H is greater than the maximum charging power, the dynamic power is issued at the maximum power of the charging pile. If H is not greater than the maximum charging power, the dynamic power H is issued until charging is completed.

[0144] Where H = PV - Pload + Pbd + Pev + Pgm, J = PV - Pload + Pev + Pbdmax + Pgm.

[0145] In one specific embodiment, a dynamic power regulation system is proposed, comprising: an edge controller (i.e., a controller); a power supply connected to the edge controller; multiple data acquisition ports, one end of which is simultaneously connected to the edge controller, and the other end of which is respectively connected to a photovoltaic power generation device, an energy storage battery, a smart meter (used to count the power consumption of the first electrical device), and a charging pile; the edge controller collects the operating status and operating power of each of the aforementioned devices in real time, and based on the collected information, the edge controller controls the operating mode of the photovoltaic power generation device and the charging and discharging status of the energy storage battery in real time, and adjusts the power delivered to the charging pile in real time to ensure that the charging pile never uses grid power during the charging process.

[0146] Furthermore, the power supply includes an electronically controlled switch that connects the mains power to the edge controller.

[0147] Furthermore, the system has several RJ45 and RS485 interfaces for connecting photovoltaic power generation equipment, energy storage batteries, smart meters, and charging piles.

[0148] Furthermore, the system has a built-in operating system for real-time data acquisition, dynamic power calculation and adjustment.

[0149] Furthermore, the system also integrates a 4G module, allowing system administrators and charging pile users to monitor its operational status in real time via terminal devices.

[0150] The power supply provides power to the edge controller. After the operating system built into the edge controller is running, it will first obtain the charging pile's working status, working mode, maximum charging power limit, minimum charging power limit, and real-time charging power through the RJ45 or RS485 port.

[0151] When the edge controller obtains the charging pile's status as charging and its operating mode as restricted mains power, the edge controller will obtain the photovoltaic power generation equipment's operating status, operating mode, and photovoltaic power generation capacity.

[0152] The edge controller also acquires the operating status of the energy storage battery, battery power, maximum battery discharge power, battery capacity, and battery depth of discharge.

[0153] The edge controller also obtains grid-side power from smart meters.

[0154] The edge controller first determines whether the working status and mode of each device in the current system can allocate power to the charging pile.

[0155] When the operating status of each device allows for the allocation of power to the charging pile, the edge controller will calculate the dynamic power A (i.e., the allocated power) that can be allocated to the charging pile without intervening in the charging and discharging control of the energy storage battery.

[0156] Furthermore, when the dynamic power A is greater than the minimum charging power limit (i.e., the lower limit) of the charging pile and less than the maximum charging power limit (i.e., the upper limit), the edge controller will allocate the dynamic power A to the charging pile to charge the electric vehicle and restart the next cycle.

[0157] Furthermore, when the dynamic power A is greater than the maximum charging power limit, the edge controller will allocate the maximum charging power limit as the dynamic power B to the charging pile to charge the electric vehicle, and restart the next cycle.

[0158] Furthermore, when the dynamic power A is less than the minimum charging power limit, the edge controller will attempt to recalculate a dynamic power C that is greater than the minimum charging power limit of the charging pile and less than the maximum charging power limit within the control range allowed by the energy storage battery.

[0159] Furthermore, if the dynamic power C cannot meet the requirement of being greater than the minimum charging power limit of the charging pile, then 0W will be allocated as dynamic power to the charging pile, and the next cycle will start again.

[0160] Furthermore, if the dynamic power C meets the requirements, the edge controller will control the charging and discharging power of the energy storage battery, allocate the dynamic power C to the charging pile to charge the electric vehicle, and restart the next cycle.

[0161] Furthermore, during the charging of electric vehicles by the charging station, the above-mentioned dynamic power adjustment will be performed cyclically, and dynamic power will be sent to the charging station at a frequency of not less than once every 5 seconds.
