It should be understood that these embodiments are provided only to enable those skilled in the art to better understand and implement the present invention, and are not intended to limit the scope of the present invention in any way. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0023] Those skilled in the art know that the embodiments of the present invention can be implemented as a system, device, apparatus, method or computer program product. Therefore, the present invention can be specifically implemented in the following forms, namely: complete hardware, complete software (including firmware, resident software, microcode, etc.), or a combination of hardware and software.

[0024] It should be noted that any number of elements in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0025] Reference below Figure 1 , Figure 1 This is a schematic diagram of the structure of a new shared battery center provided by an embodiment of the present invention. Figure 1 As shown, a new type of shared battery center includes:

[0026] A micro wind turbine generator, a PV photovoltaic module, a wind-solar storage and charging DC controller, a shared battery cabinet, a bracket and a DC cable. The micro wind turbine generator and the PV photovoltaic module are installed on the bracket. The micro wind turbine generator and the PV photovoltaic module are connected to the wind-solar storage and charging DC controller through a DC cable. The wind-solar storage and charging DC controller is connected to the shared battery cabinet through a communication cable. The micro wind turbine generator and the PV photovoltaic module are used to generate DC power. The DC cable includes a DC input cable and a DC output cable.

[0027] It should be noted that the present embodiment relates to a new type of shared battery center, which includes a micro wind turbine and a PV photovoltaic module, which are used together to generate direct current. Here, the micro wind turbine refers to a small wind power generation device that can convert wind energy into electrical energy; and the PV photovoltaic module refers to a solar panel that can convert solar energy into electrical energy. Both devices are mounted on a bracket, the function of which is to support these devices and keep them in a suitable position to obtain energy.

[0028] Specifically, the micro wind turbine generator and the PV photovoltaic module are connected to the wind-solar storage and charging DC controller through a DC cable. The DC cable includes a DC input cable and a DC output cable, which are used to transmit the DC power generated by the wind turbine generator and the photovoltaic module.

[0029] More specifically, in this embodiment, the length and specification of the DC cable are set according to the distance between the wind turbine generator and the photovoltaic assembly and the controller and the demand for power transmission. For example, if the distance between the devices is far, it may be necessary to use a longer cable and ensure that the cable can withstand the corresponding current and voltage.

[0030] Preferably, in order to further improve the transmission efficiency and safety of electric energy, the DC cable can be made of special materials with high insulation performance and weather resistance. In addition, in order to adapt to different environmental conditions, the design of the bracket can also be optimized, such as increasing its height to obtain better wind resources, or adjusting the angle to maximize the reception of solar energy.

[0031] Furthermore, in practical applications, different types of wind turbines and photovoltaic modules can be selected according to geographical locations and climatic conditions to achieve optimal energy conversion efficiency.

[0032] like Figure 2 As shown, the direct current generated by the micro wind turbine generator and the PV photovoltaic module is connected to a direct current filter through a direct current input cable. The direct current filter includes a direct current filter 1 and a direct current filter 2, which are respectively used to filter the clutter in the direct current generated by the micro wind turbine generator and the PV photovoltaic module.

[0033] It should be noted that this embodiment describes a new shared battery center, in which the direct current generated by the micro wind turbine generator and the PV photovoltaic module is connected to the direct current filter through a direct current input cable. Here, the direct current filter refers to a device used to reduce the clutter in the direct current to improve the power quality. The direct current filter includes a direct current filter 1 and a direct current filter 2, which are used to filter the clutter in the direct current from the micro wind turbine generator and the PV photovoltaic module, respectively.

[0034] Specifically, DC filter 1 and DC filter 2 can be different types of filters, such as low-pass filters or high-pass filters, depending on the frequency of the clutter that needs to be filtered. The parameters of these filters, such as capacitance and inductance, can be set according to the characteristics of the DC power generated by the wind turbine generator and the photovoltaic module. For example, if the clutter is mainly concentrated in the high frequency band, a low-pass filter with a larger capacitance value may be required to effectively filter these clutters.

[0035] Preferably, in order to further improve the purity of electric energy and the stability of the system, the DC filter can adopt a multi-stage filtering design, that is, multiple filters with different parameters are connected in series after the DC input cable to gradually reduce the clutter in different frequency bands.

[0036] Furthermore, digital signal processing technology can be used to achieve more accurate filtering effects. In practical applications, the filter parameters can be adjusted according to the environmental noise level and the specific requirements of the equipment, or an intelligent filter with automatic adjustment function can be selected to adapt to different working conditions.

[0037] In some embodiments, the DC power filtered by the DC filter is connected to the MPPT maximum power tracking circuit, and the MPPT maximum power tracking circuit includes MPPT maximum power tracking circuit 1 and MPPT maximum power tracking circuit 2, which are used to track the maximum power points of the DC power generated by the micro wind turbine generator and the PV photovoltaic module, respectively.

[0038] It should be noted that, in this embodiment, the DC power filtered by the DC filter will be connected to the MPPT maximum power tracking circuit. Here, the MPPT maximum power tracking circuit refers to an electronic circuit that can track and control the working point of the solar panel or wind turbine so that it is always in the maximum power output state. The MPPT maximum power tracking circuit includes an MPPT maximum power tracking circuit 1 and an MPPT maximum power tracking circuit 2, which are used to track the maximum power point of the DC power generated by the micro wind turbine and the PV photovoltaic module, respectively.

[0039] Specifically, the MPPT maximum power tracking circuit 1 and the MPPT maximum power tracking circuit 2 can be parameterized according to the characteristics of the micro wind turbine generator and the PV photovoltaic module. These parameters include operating voltage, operating current, maximum power point voltage, etc. For example, for PV photovoltaic modules, the MPPT circuit can dynamically adjust the operating point according to light intensity and temperature changes to ensure that the maximum power output can be achieved under different environmental conditions. The control algorithms of these circuits can be based on traditional P&O (perturbation and observation) algorithms, or more advanced algorithms such as fuzzy logic control or neural network control.

[0040] Preferably, in order to improve the adaptability and efficiency of the system, the MPPT maximum power tracking circuit can be integrated into a microcontroller, which can monitor and adjust the operating point in real time.

[0041] Furthermore, the MPPT algorithm can be optimized through software upgrades to adapt to new component characteristics or environmental changes. In practical applications, a multi-MPPT design can also be considered, that is, each component or component group has its own MPPT circuit, which can further improve the flexibility and efficiency of the system.

[0042] In some embodiments, the DC power processed by the MPPT maximum power tracking circuit is aggregated into a DC bus, which is used to collect and distribute DC power.

[0043] It should be noted that in this embodiment, the DC power processed by the MPPT maximum power tracking circuit will be aggregated into the DC bus. Here, the DC bus refers to an electrical system that is used to collect and distribute DC power. The DC bus is the central point connecting multiple power sources and loads, which allows power to flow from one power source to multiple loads, or from multiple power sources to one load.

[0044] Specifically, the design and configuration of the DC bus needs to consider the total power demand, voltage level, and current capacity of the system. For example, the DC bus can be composed of multiple cables connected in parallel to provide sufficient current capacity while maintaining voltage stability. The voltage level of the bus can be set according to the maximum voltage requirement of the system, while the current capacity needs to be determined according to the maximum load requirement of the system. In addition, the DC bus can also be equipped with protection devices such as fuses or circuit breakers to prevent overload and short circuit.

[0045] Preferably, in order to improve the safety and reliability of the system, the DC bus can adopt an isolation design, that is, there is an isolation device between each power supply and load, so that other parts can be protected from being affected when a part fails.

[0046] Furthermore, a monitoring system can be integrated on the DC bus to monitor parameters such as voltage, current and temperature in real time to facilitate fault diagnosis and preventive maintenance. In practical applications, the use of flexible DC bus technology can also be considered, which can reduce the use of cables and improve the flexibility and scalability of the system.

[0047] In some embodiments, the DC bus is connected to a DC-DC converter, and the DC-DC converter is used to convert the DC power on the DC bus into the voltage and current required by the battery module.

[0048] It should be noted that, in this embodiment, the DC bus is connected to a DC-DC converter, which converts the DC power on the DC bus into the voltage and current required by the battery module. Here, the DC-DC converter refers to a power conversion device that can convert one DC voltage into another DC voltage to meet the charging and discharging requirements of different battery modules.

[0049] Specifically, the DC-DC converter can be parameterized according to the voltage and current requirements of the battery module. For example, if the battery module requires a voltage of 48V and a current of 10A, the converter needs to be able to provide such an output. Parameters such as the converter's efficiency, conversion ratio, and response time also need to be determined based on the overall performance requirements of the system. In addition, the converter can also include protection functions such as overcurrent, overvoltage, and short circuit to ensure the safe and stable operation of the battery module.

[0050] Preferably, in order to improve conversion efficiency and system flexibility, the DC-DC converter may adopt a modular design, so that converter modules may be added or removed as needed to adapt to different power and load requirements.

[0051] Furthermore, the converter can also integrate intelligent control functions, such as PWM (pulse width modulation) control, to achieve more precise voltage and current control. In practical applications, it is also possible to consider using a bidirectional DC-DC converter, which can both charge and discharge the battery module, thereby improving energy efficiency.

[0052] In some embodiments, the DC-DC converter includes a DC-DC converter 1 and a DC-DC converter 2, and the DC-DC converter 1 and the DC-DC converter 2 are used to process DC power from a micro wind turbine generator and a PV photovoltaic module, respectively.

[0053] It should be noted that, in this embodiment, the DC-DC converter includes a DC-DC converter 1 and a DC-DC converter 2, which are used to process the DC power from the micro wind turbine generator and the PV photovoltaic module, respectively. Here, the DC-DC converter 1 and the DC-DC converter 2 refer to two independent converter units, which can be optimized for different power supply characteristics.

[0054] Specifically, the parameters of the DC-DC converter 1 and the DC-DC converter 2 can be set according to the characteristics of the DC power generated by the micro wind turbine generator and the PV photovoltaic module. For example, if the DC voltage generated by the wind turbine generator is higher, while the DC voltage generated by the photovoltaic module is lower, then the two converters can be set with different conversion ratios and working modes respectively. The parameters of the converter, such as efficiency, conversion ratio and response time, also need to be determined according to the overall performance requirements of the system.

[0055] Preferably, in order to improve the adaptability and efficiency of the system, different control strategies can be adopted for the DC-DC converter 1 and the DC-DC converter 2. For example, the DC-DC converter 1 can adopt constant voltage control to adapt to the high voltage characteristics of the wind turbine generator, while the DC-DC converter 2 can adopt constant current control to adapt to the low voltage characteristics of the photovoltaic module.

[0056] Furthermore, the two converters can also integrate intelligent control functions, such as PWM control, to achieve more precise voltage and current control. In practical applications, it is also possible to consider using a programmable logic controller (PLC) to achieve remote monitoring and control of the two converters to improve the flexibility and reliability of the system.

[0057] In some embodiments, the wind-solar-storage-charging DC controller can monitor the status of each battery module in the shared battery cabinet and adjust the charging and discharging actions, and the shared battery cabinet can display the status of each battery module. The wind-solar-storage-charging DC controller exchanges data with the shared battery cabinet through a communication cable.

[0058] It should be noted that in this embodiment, the wind-solar storage-charge DC controller has the function of monitoring the status of each battery module in the shared battery cabinet and adjusting the charging and discharging actions. Here, the wind-solar storage-charge DC controller refers to a device that integrates monitoring and control functions. It can monitor the voltage, current, temperature and other parameters of the battery module in real time, and adjust the charging and discharging strategy according to these parameters to protect the battery and extend its service life.

[0059] Specifically, the wind-solar storage-charge DC controller can monitor the status of the battery module through built-in sensors and algorithms. For example, it can set thresholds to monitor the battery charging voltage and current to prevent overcharging and over-discharging. The controller can also predict the health of the battery based on the battery charging status and usage history, and adjust the charging and discharging strategy accordingly. The communication cable is used to connect the controller to the shared battery cabinet to achieve real-time data transmission.

[0060] Preferably, the wind-solar storage-charge DC controller can integrate a user interface that allows operators to view battery status and adjust settings. In addition, the controller can also connect to a remote server via a wireless network to achieve remote monitoring and fault diagnosis. In practical applications, it is also possible to consider using artificial intelligence algorithms to optimize charging and discharging strategies to adapt to different usage scenarios and improve battery life.

[0061] In some embodiments, an AC input is also included as a backup power source, and the AC input charges the shared battery cabinet through an AC-DC converter, and the AC-DC converter is used to convert the AC input into a DC output.

[0062] It should be noted that, in this embodiment, the system also includes an AC input as a backup power source, and the AC input charges the shared battery cabinet through an AC-DC converter. Here, the AC input refers to an AC power source from a power grid or a generator, and the AC-DC converter refers to a device that converts AC power into DC power for use in the battery cabinet.

[0063] Specifically, the AC-DC converter can set parameters according to the charging requirements of the shared battery cabinet. For example, if the battery cabinet requires 48V DC, the converter needs to be able to provide the corresponding DC output. Parameters such as the converter's power level, conversion efficiency, and output stability also need to be determined based on the overall performance requirements of the system. In addition, the converter can also include safety features such as overload protection, short circuit protection, and overheating protection.

[0064] Preferably, in order to improve the reliability and flexibility of the system, the AC-DC converter can be designed as a modular structure so that modules can be added or replaced as needed. In addition, the converter can also integrate intelligent control functions such as PWM control to achieve more accurate voltage and current control.

[0065] Furthermore, in practical applications, it is also possible to consider using a bidirectional AC-DC converter, which can be used to charge from an AC power source and also feed the power in the battery cabinet back to the grid when needed, thereby improving energy utilization efficiency.

[0066] In some embodiments, the shared battery cabinet includes a plurality of battery modules, each of which can be used to power an external device. The shared battery cabinet also includes a DC output switch for controlling the DC output of the battery module.

[0067] It should be noted that in this embodiment, the shared battery cabinet includes multiple battery modules, which can provide power to external devices. Here, the battery module refers to the basic unit that constitutes the battery cabinet, and each module contains a certain number of battery cells, which can independently provide DC power to the device.

[0068] Specifically, the battery modules in the shared battery cabinet can be configured according to the power requirements of the external device. For example, if the external device requires high power output, the battery cabinet can be configured with high-capacity and high-power battery modules. The parameters such as voltage, capacity and output interface of each battery module need to be set according to the specific requirements of the device. In addition, the battery module can also include a battery management system (BMS) to monitor the battery status, ensure safety and optimize performance.

[0069] Preferably, the shared battery cabinet can be designed as a modular structure, allowing the battery modules to be added or removed as needed. In addition, the battery cabinet can also be equipped with an intelligent control unit to achieve remote monitoring and maintenance of the battery modules.

[0070] Furthermore, in practical applications, it is also possible to consider using battery modules of different chemical types, such as lithium-ion batteries or lead-acid batteries, to adapt to different application scenarios and cost-effectiveness.

[0071] In some embodiments, the support is used to support a micro wind turbine generator and a PV photovoltaic module so that they are in a suitable position to obtain energy, and the support has sufficient strength and stability.

[0072] It should be noted that, in this embodiment, the shared battery cabinet further includes a DC output switch for controlling the DC output of the battery module. Here, the DC output switch refers to an electronic switch that can control the flow of DC power in the battery cabinet to ensure safe and efficient power distribution.

[0073] Specifically, the DC output switch can be configured based on the output parameters of the battery module and the input requirements of the external device. For example, if the battery module provides 48V DC power and the external device requires 24V, the DC output switch needs to be able to adjust the voltage to meet the device requirements. Parameters such as the switch's current carrying capacity, voltage level, and response time need to be determined based on the overall performance requirements of the system.

[0074] Preferably, the DC output switch can integrate protection functions such as over-current protection and short-circuit protection to prevent damage to external devices or battery modules. In addition, the switch can also adopt intelligent control, such as optimizing power distribution through software algorithms.

[0075] Furthermore, in practical applications, it is also possible to consider using a programmable DC output switch to achieve more flexible power management, such as dynamically adjusting the output voltage and current according to the usage of external devices.

In addition, the communication cable connection between the wind and solar storage and charging DC controller and the shared battery cabinet can monitor the battery status in real time and intelligently adjust the charging and discharging actions, thereby enhancing the stability and reliability of the system.

[0077] Furthermore, the independent design of the DC-DC converter allows the DC power from different energy sources to be processed separately, improving the adaptability and efficiency of the system. The setting of AC input as a backup power source can provide additional power support when renewable energy is insufficient, enhancing the continuous power supply capability of the system. The multi-battery module design and DC output switch of the shared battery cabinet can provide a stable and reliable power supply for external devices, while displaying the status of each battery module to improve the transparency of the system and the convenience of user operation. The design of the bracket ensures that the micro wind turbine generator and PV photovoltaic module can obtain energy stably, while the DC output switch of the shared battery cabinet provides precise control for the DC output of the battery module, which can further enhance the safety and flexibility of the system.
