[0020] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] Reference Figure 1The present invention provides an integrated energy storage power supply system, including a circuit board 10 and a battery pack 70. The circuit board 10 is provided with a battery management module 20, a battery connection module 30, a charging module 40, a discharge module 50, and a photovoltaic module 60. The battery connection module 30, the charging module 40, the discharge module 50, and the photovoltaic module 60 are all electrically connected to the battery management module 20, and the battery pack 70 is electrically connected to the battery connection module 30. In other words, the battery management module 20 is electrically connected to the battery pack 70. In the energy storage power supply system, the battery management module 20 is responsible for real-time monitoring of battery status, including voltage, temperature, and current, managing the charging and discharging process to prevent overcharging and over-discharging, and ensuring safe battery operation. It also achieves battery cell balancing, provides multiple safety protection functions, supports communication with external devices for data transmission and control, optimizes charging strategies, performs fault diagnosis, and records usage history data to extend battery life and improve system reliability.

[0024] The charging module 40 is electrically connected to the discharging module 50. At the same time, both the charging module 40 and the discharging module 50 are electrically connected to the battery pack 70 via the battery connection module 30. When the energy storage power supply system of the present invention is supplying power to an external electrical appliance, if the charging module 40 is not connected to an external power source, the battery pack 70 provides electrical energy to power the external electrical appliance. If the charging module 40 is connected to an external power source, the external power source directly supplies power to the external electrical appliance via the discharging module 50, while simultaneously charging the battery pack 70 via the battery connection module 30. When the battery pack 70 is fully charged and the charging module 40 is connected to an external power source, the external power source is preferentially used to power the external electrical appliance.

[0025] Furthermore, the battery connection module 30 includes a first positive terminal 31 and a first negative terminal 32 , and the battery pack 70 is provided with a second negative terminal 71 electrically connected to the first positive terminal 31 and a second positive terminal 72 electrically connected to the first negative terminal 32 .

[0026] Furthermore, the photovoltaic module 60 includes a first photovoltaic output terminal and a second photovoltaic output terminal. The first photovoltaic output terminal is electrically connected to the first positive terminal 31, and the second photovoltaic output terminal is electrically connected to the first negative terminal 32. In other words, the photovoltaic module 60 is electrically connected to the battery pack 70, thereby charging the battery pack 70 through photovoltaic power, providing the energy storage power system with various energy sources required for energy storage.

[0027] It should be noted that the photovoltaic module 60 is a device that converts light energy into electrical energy. It is composed of multiple photovoltaic cells (also known as solar cells) that absorb sunlight and convert it into direct current. Each photovoltaic cell is made of a semiconductor material (such as single-crystal silicon, polycrystalline silicon, or thin-film material). When exposed to sunlight, this material releases free electrons, generating an electric current. Under the control of the battery management module 20, this current is appropriately directed to the battery pack 70, thereby charging the battery pack 70.

[0028] Optionally, the charging module 40 is an AC input interface, and the discharging module 50 is an AC output interface, and both the AC input interface and the AC output interface are electrically connected to the battery pack 70 .

[0029] Optionally, the circuit board 10 is further provided with auxiliary components 80, which are electrically connected to the battery management module 20. The auxiliary components 80 include resistors for limiting current flow, voltage division, or energy consumption; capacitors for storing and releasing electrical energy, filtering, decoupling, etc.; inductors for storing magnetic energy, filtering, impedance matching, etc.; diodes for allowing unidirectional current flow and for rectification, voltage stabilization, signal detection, etc.; transistors for amplifying or switching electronic signals; fuses for protecting circuits that blow when the current exceeds a specific value, disconnecting the circuit; optocouplers for achieving electrical isolation and transmitting data via optical signals; transformers for voltage conversion; and filters for signal processing and removing unwanted frequency components.

[0030] Optionally, the battery management module 20 includes a temperature monitoring unit and an over-temperature protection circuit. The temperature monitoring unit is used to monitor the operating temperature of the battery pack 70. When the temperature exceeds a preset threshold, the over-temperature protection circuit automatically cuts off the connection between the battery pack 70 and the battery connection module 30.

[0031] Specifically, the temperature monitoring unit is composed of a temperature sensor (such as a thermistor, infrared sensor, or thermocouple) and can monitor the operating temperature of the battery pack 70 in real time. The temperature monitoring unit monitors temperature changes on or within the battery pack 70 and converts them into electrical signals. The control system of the battery management module 20 processes and analyzes these signals, and promptly identifies any overheating of the battery pack 70.

[0032] When the temperature monitoring unit detects that the battery pack 70 is overheating, the overtemperature protection circuit immediately activates to protect the energy storage power system's circuitry. Specifically, the overtemperature protection circuit includes a switching element (such as a relay or MOSFET). When a high-temperature alarm is triggered, the circuit automatically disconnects the power supply between the battery pack 70 and the load or charging device, quickly preventing further battery operation. This reduces the risk of damage from overheating and ensures the safety and stability of the energy storage power system. By implementing overtemperature protection, the system effectively prevents energy storage power system failures, damage, or even more serious safety incidents caused by abnormal temperatures.

[0033] Optionally, both the charging module 40 and the photovoltaic module 60 are equipped with a power conditioning unit, which is used to adjust the input power to the battery pack 70 to adjust charging efficiency and extend the life of the battery pack 70. The power conditioning unit, which includes one of a microcontroller, a digital signal processor (DSP), and an MPPT controller, can monitor parameters such as the voltage, temperature, and remaining charge of the battery pack 70 in real time, and control the power output of the input power source to implement an optimal charging strategy. Specifically, when the battery pack 70 is low in charge, the power conditioning unit can increase the charging power to accelerate charging. When the battery pack 70 is nearly fully charged, the power conditioning unit can automatically reduce the power output to prevent overcharging, thereby optimizing charging efficiency, protecting the battery, and extending its life.

[0034] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
