[0030] Example 1

[0031] Embodiment 1 of this utility model provides a control circuit for an energy storage device. This control circuit is used in energy storage devices, such as... Figure 1 As shown, the control circuit of the energy storage device includes a first battery module 1, a second battery module 2, a control module 3, and a wireless communication module 4.

[0032] The first battery module 1 is electrically connected to the first end of the control module 3 and the first end of the wireless communication module 4; wherein, the first battery module 1 is a module capable of storing electrical energy and outputting electrical energy to supply power to electrical equipment, and the first battery module 1 refers to the main source of electrical energy for the energy storage device used in the control circuit of the energy storage device.

[0033] The second battery module 2 is electrically connected to the second end of the control module 3 and the second end of the wireless communication module 4; wherein, the second battery module 2 is a module capable of storing electrical energy and outputting electrical energy to supply power to electrical equipment, and it is used to provide power to the control module 3 and the wireless communication module 4 when in sleep mode.

[0034] The control module 3 is used to output a sleep signal to the first battery module 1 and the second battery module 2. The first battery module 1 is used to stop outputting power based on the sleep signal, and the second battery module 2 is used to output power to the control module 3 and the wireless communication module 4 based on the sleep signal.

[0035] In this context, control module 3 refers to the functional module that performs logic control within the control circuit of the energy storage device. In some embodiments, control module 3 includes an MCU; in other embodiments, it can be any other module capable of logic control, without specific limitations. The sleep signal is a signal that instructs the control circuit of the energy storage device to enter a sleep state. In some embodiments, the control circuit of the energy storage device includes a power-off button, which is electrically connected to control module 3. When the power-off button is pressed, an electrical signal is generated to control module 3, indicating that it should enter sleep mode. Control module 3 then sends a sleep signal (an electrical signal) to the first battery module 1 and the second battery module 2, shutting off the power output of the first battery module 1. The second battery module 2 then supplies power to control module 3 and wireless communication module 4, which are in sleep mode.

[0036] The wireless communication module 4 receives a power-on signal and controls the first battery module 1 to output power based on the power-on signal, thereby waking up the control module 3. The wireless communication module 4 is an electronic device for wireless communication, based on radio technology, enabling wireless data transmission and communication between devices. The power-on signal is an electrical signal indicating that the device is exiting sleep mode. In some embodiments, a user can wirelessly communicate with the wireless communication module 4 via a smart device, sending a power-on signal to the wireless communication module 4 through the smart device. The smart device can be one or more of a smartphone, smart computer, or smartwatch. When the smart device is a smartphone, the user can send the power-on signal through an app on the smartphone. Upon receiving the power-on signal, the wireless communication module 4 controls the first battery module 1 to output power. At this time, the control module 3 is activated by power supply, exits sleep mode, and the energy storage device can operate normally.

[0037] The above solution, by setting up a first battery module 1 and a second battery module 2, allows the second battery module 2 to power the control module 3 and the wireless communication module 4 during sleep mode. This eliminates the need for the first battery module 1 to use its power during sleep, preventing over-discharge and protecting it from damage, thus extending its lifespan. Furthermore, since the wireless communication module 4 is powered by the second battery module 2 during sleep mode, it can receive the user's remotely transmitted power-on signal and control the first battery module 1 to output power to wake up the control module 3, achieving remote activation and improving user experience. Therefore, this solution solves the problems of easy over-discharge during sleep mode and difficulty in remote activation of energy storage devices.

[0038] In optional embodiments of this utility model, such as Figure 2As shown, the first battery module 1 includes a first battery module 11 and a power supply circuit 12. The output terminal of the first battery module 11 is electrically connected to the input terminal of the power supply circuit 12, and the output terminal of the power supply circuit 12 is electrically connected to both the control module 3 and the wireless communication module 4.

[0039] The first battery module 11 is used for large-scale energy storage and release in the energy storage device. The power supply circuit 12 is an independent module containing multiple electronic components and circuits. It converts the input voltage into a voltage suitable for the circuit. Specifically, the power supply circuit 12 converts the output voltage of the first battery module 11 into the operating voltage of the control module 3 and the wireless communication module 4, supplying power to them when the energy storage device is powered on. Furthermore, since the first battery module 11 does not need to output power during sleep mode, its power consumption is reduced, lowering the risk of damage during prolonged storage.

[0040] Based on the above embodiments, the first battery module 11 includes a battery management system and a first battery. The output terminal of the first battery is electrically connected to the input terminal of the battery management system, and the output terminal of the battery management system is electrically connected to the input terminal of the power supply circuit 12. The battery management system (BMS) is mainly used for intelligent management and maintenance of the first battery, monitoring its status, and preventing overcharging and over-discharging to extend its service life.

[0041] For example, the first battery module 11 also includes a MOSFET switching circuit, which is electrically connected between the battery management system and the power supply circuit 12. When the energy storage device is powered off and enters sleep mode, the MOSFET switching circuit is open. At this time, the first battery does not output power to the power supply circuit 12, and the second battery module 2 supplies power to the control module 3 and the wireless communication module 4. At this time, the first battery module 11 enters sleep mode, reducing the power consumption of the first battery module 11 after power-off. When the energy storage device needs to be remotely started, the wireless communication module 4 receives a power-on signal and controls the first battery module 11 to activate power supply. At this time, the MOSFET switching circuit closes to supply power to the power supply circuit 12, thereby activating the control module 3 and enabling the energy storage device to operate normally.

[0042] In optional embodiments of this utility model, such as Figure 2As shown, the output terminal of the power supply circuit 12 is electrically connected to the charging terminal of the second battery module 2. Thus, the first battery module 11 can also charge the second battery module 2, ensuring that the control circuit of the entire energy storage device can meet its service life. In some embodiments, when the energy storage device is powered on and detects that the voltage of the second battery module 2 is lower than a set voltage, the control module 3 controls the first battery module 11 to charge the second battery module 2 through the power supply circuit 12, preventing the second battery module 2 from having insufficient power to provide power to the control module 3 and the wireless communication module 4 during sleep mode, thus ensuring that the entire energy storage device can meet its service life.

[0043] In an optional embodiment of this invention, the second battery module 2 includes a second battery for storing and providing electrical energy. In some embodiments, the second battery module 2 further includes a charging protection circuit to protect the second battery during charging, preventing damage due to overcharging, over-discharging, short circuits, or abnormal temperatures. In some embodiments, the second battery module 2 also includes an RTC circuit, which is a real-time clock circuit whose main function is to provide a precise time reference for the energy storage device.

[0044] In optional embodiments of this utility model, such as Figure 2 As shown, the control circuit of the energy storage device also includes a power-on control circuit 10. The output terminal of the wireless communication module 4 is electrically connected to the input terminal of the power-on control circuit 10, and the output terminal of the power-on control circuit 10 is electrically connected to the first battery module 1. The wireless communication module 4 is used to output a power-on activation signal to the power-on control circuit 10 based on the power-on signal, and the power-on control circuit 10 is used to activate the first battery module 1 to output electrical energy based on the power-on activation signal.

[0045] In this context, the power-on control circuit 10 refers to the module capable of controlling the power-on of the first battery module 1. The power-on activation signal is an electrical signal that instructs the power-on control circuit 10 to activate the first battery module 1 and output power. In some embodiments, the power-on control circuit 10 includes a switching circuit, which can be a MOSFET switching circuit, a relay switching circuit, etc. When the wireless communication module 4 outputs the power-on activation signal to the switching circuit, the switching circuit closes, providing an electrical signal to the first battery module 1, thus activating the first battery module 1. After activation, the first battery module 1 supplies power to the control module 3 and the wireless communication module 4. With power supply activated, the energy storage device can then operate normally. It is understood that in other embodiments, the power-on control circuit 10 can also be other types of circuits, as long as they can control the first battery module 1 to activate and supply power.

[0046] In an optional embodiment of this utility model, the wireless communication module 4 includes at least one of a Bluetooth module, a WIFI module, a 4G module, a 5G module, and an IoT module. The Bluetooth module is a device for wireless communication, enabling wireless transmission between devices through Bluetooth technology. The WIFI module is an important component of a router, providing necessary support for wireless network connections. The 4G module is a network connection device supporting fourth-generation mobile communication technology, achieving high-speed data transmission and access through LTE technology. The 5G module is mainly used to connect IoT devices such as sensors, equipment, and machines, enabling high-speed communication and data transmission. Compared to the 4G module, the 5G module has higher transmission speeds, lower latency, and greater capacity. The IoT module is a hardware device used to control the operation and status of IoT devices, as well as their interaction with other devices. Therefore, the Bluetooth module, WIFI module, 4G module, 5G module, and IoT module can all achieve wireless communication, and the wireless communication module 4 can include one or more of them to achieve wireless communication with smart devices; no specific limitation is made here.

The inverter module 5 can convert DC power to AC power to meet the power needs of different devices and systems. Therefore, the energy storage device can convert the DC power output from the first battery module 1 into AC power through the inverter module 5, thereby supplying power to AC loads.

The USB module 6 is typically used to enable communication and data transmission between the device and the USB interface. Therefore, a device with a USB interface can be connected to the USB module 6, and then the first battery module 1 can be powered by the device with the USB interface through the USB module 6.

[0049] In optional embodiments of this utility model, such as Figure 2As shown, the control circuit of the energy storage device also includes a vehicle charging module 7. The first battery module 1 is electrically connected to the power supply terminal of the vehicle charging module 7, and the control module 3 is electrically connected to the control terminal of the vehicle charging module 7. The main function of the vehicle charging module 7 is to convert the input electrical energy into DC power suitable for charging the electric vehicle's power battery, and then safely and efficiently output it to the electric vehicle's power battery through a specific circuit structure. Therefore, through the vehicle charging module 7, the electrical energy of the first battery module 1 can be converted into DC power suitable for charging the electric vehicle's power battery, thus providing power to the electric vehicle.
