The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0031] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly specifying the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. In the description of the embodiments of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] The use of energy storage power supplies is becoming more and more popular, and there are also many ways to charge energy storage power supplies. The current ways to charge energy storage power supplies include AC charging, communication protocol charging, solar charging, and car charging. However, the current energy storage power supplies need to be equipped with corresponding charging ports for different charging methods, resulting in a large number of charging ports for the energy storage power supplies, a more complex circuit design, and a higher circuit material cost. To solve this problem, the present application provides a control method for an energy storage power supply (as shown in FIG1 ), an energy storage power supply 100 (as shown in FIG2 or FIG10 ), and an energy storage system 1000 (as shown in FIG2 and FIG10 ).

[0033] Please refer to FIG1 for a control method of an energy storage power supply according to an embodiment of the present application. In conjunction with FIG2 , the energy storage power supply 100 is provided with a Type-C port 10 , which is configured to be electrically connected to an external power supply 300 . The control method includes:

[0034] 04: When the external power source 300 is connected to the Type-C port 10, detecting the charging type of the external power source 300 connected to the Type-C port 10, the charging type including at least one of solar charging, communication protocol charging, and vehicle charging; and

[0035] 06: Control the energy storage power supply 100 to start a charging mode corresponding to the charging type of the external power supply 300, so that the external power supply 300 charges the battery module 30 in the energy storage power supply 100 in the corresponding charging mode.

[0036] With reference to Figure 2 , an energy storage power supply 100 according to an embodiment of the present application includes a Type-C port 10, a battery module 30, a charging type detection module 50 electrically connected to the Type-C port 10, and a control module 70 electrically connected to the charging type detection module 50. The Type-C port 10 is configured to be electrically connected to an external power source 300. The battery module 30 is configured to store electrical energy charged by the external power source 300 to the energy storage power supply 100. The charging type detection module 50 is configured to, when the external power source 300 is connected to the Type-C port 10, detect the charging type of the connected external power source 300, which may include at least one of solar charging, communication protocol charging, and vehicle charging. The control module 70 is configured to control the energy storage power supply 100 to activate a charging mode corresponding to the charging type of the external power source 300, so that the external power source 300 charges the battery module 30 in the corresponding charging mode.

[0037] Specifically, energy storage power supply 100 is a structure for storing electrical energy and charging other electrical devices. For example, energy storage power supply 100 can be used to charge cooking equipment, lighting equipment, or electric vehicles. External power supply 300 is a structure for charging energy storage power supply 100. For example, external power supply 300 can be a solar power generation module 500 or a vehicle charger.

[0038] The Type-C port 10 is located within the energy storage power supply 100, with one end protruding from the power supply 100. This port is used for electrical connection to other components. If the other component is an external power supply 300, the external power supply 300 can be connected to the Type-C port 10 to charge the energy storage power supply 100. If the other component is a load, the load can be connected to the Type-C port 10 to allow the energy storage power supply 100 to charge the load.

[0039] The battery module 30 is used to store the electrical energy charged by the external power source 300 to the energy storage power supply 100. Furthermore, when the energy storage power supply 100 is charging other electrical devices, the battery module 30 is used to release the stored electrical energy to provide power to the other electrical devices. The battery module 30 may include one or more battery cells, which may be prismatic or cylindrical.

[0040] After the Type-C port 10 is electrically connected to the external power source 300, electrical signals from the external power source 300 enter the charging type detection module 50 through the Type-C port 10. The charging type detection module 50 then detects the charging type of the external power source 300. After the charging type detection module 50 determines the charging type of the external power source 300, it transmits a signal to the control module 70. The control module 70 controls the energy storage power source 100 to activate the corresponding charging mode. This ensures that the charging mode of the energy storage power source 100 matches the charging type of the connected external power source 300, allowing the external power source 300 to charge the energy storage power source 100.

[0041] Among them, the charging type refers to the charging method of the external power supply 300, and the charging types of this application include solar charging, car charging and communication protocol charging. Solar charging can be connected to the Type-C port 10 of the energy storage power supply 100 through a solar panel, and the solar panel is used to convert solar energy into electrical energy, thereby charging the energy storage power supply 100. Car charging can be connected to the Type-C port 10 of the energy storage power supply 100 through a vehicle charging head, so that the vehicle battery charges the energy storage power supply 100. Communication protocol charging can reach a charging agreement between the energy storage power supply 100 and the external power supply 300, thereby enabling the external power supply 300 to charge the energy storage power supply 100. In this application, communication protocol charging is power delivery (PD) charging, which is a type of charging that complies with the fast charging standard.

[0042] The charging mode of the energy storage power supply 100 of the present application includes three modes, which correspond to the three charging types of solar charging, vehicle charging and communication protocol charging, namely, solar charging mode, vehicle charging mode and communication protocol charging mode. When the charging type of the external power supply 300 is solar charging, the energy storage power supply 100 starts the corresponding solar charging mode, so that the external power supply 300 can charge the battery module 30 in the energy storage power supply 100 in the solar charging mode. When the charging type of the external power supply 300 is vehicle charging, the energy storage power supply 100 starts the corresponding vehicle charging mode, so that the external power supply 300 can charge the battery module 30 in the energy storage power supply 100 in the vehicle charging mode. When the charging type of the external power supply 300 is communication protocol charging, the energy storage power supply 100 starts the corresponding communication protocol charging mode, so that the external power supply 300 can charge the battery module 30 in the energy storage power supply 100 in the communication protocol charging mode.

[0043] The energy storage power supply control method and energy storage power supply 100 of the embodiments of the present application, by providing a charging type detection module 50 and a control module 70, enable the energy storage power supply 100 to detect the charging type of the external power supply 300 when the external power supply 300 is connected to the energy storage power supply 100, thereby enabling the energy storage power supply 100 to activate the corresponding charging mode, so that the external power supply 300 can charge the energy storage power supply 100. Compared to existing energy storage power supplies, the energy storage power supply 100 of the present application has a single Type-C port 10 that supports multiple charging modes, has a smaller number of charging ports, simplifies the circuit design, and can save circuit material costs.

[0044] Please refer to FIG3 . In some embodiments, 04: detecting the charging type of the external power source 300 connected to the Type-C port 10 includes: 041: detecting whether a communication protocol exists between the energy storage power source 100 and the external power source 300; and

[0045] 043: When a communication protocol exists between the energy storage power supply 100 and the external power supply 300, determine that the charging type of the external power supply 300 connected to the Type-C port 10 is communication protocol charging.

[0046] In conjunction with Figures 10 and 11, in some embodiments, the charging type detection module 50 includes a protocol IC detection circuit 51, which is communicatively connected to the Type-C port 10. The protocol IC detection circuit 51 is configured to: detect whether a communication protocol exists between the energy storage power supply 100 and the external power supply 300, and if a communication protocol exists between the energy storage power supply 100 and the external power supply 300, determine that the charging type of the external power supply 300 connected to the Type-C port 10 is communication protocol charging.

[0047] Specifically, after the Type-C port 10 is electrically connected to the external power supply 300, the protocol IC detection circuit 51 is used to identify whether a communication protocol exists between the energy storage power supply 100 and the external power supply 300. If no communication protocol exists between the energy storage power supply 100 and the external power supply 300, the protocol IC detection circuit 51 determines that the charging type of the external power supply 300 is not communication protocol charging. If a communication protocol exists between the energy storage power supply 100 and the external power supply 300, the protocol IC detection circuit 51 determines that the charging type of the external power supply 300 is communication protocol charging. At this time, the control module 70 controls the energy storage power supply 100 to activate the corresponding communication protocol charging mode, so that the external power supply 300 charges the battery module 30 in the energy storage power supply 100 in the communication protocol charging mode.

[0048] A communication protocol is an agreement reached through communication and negotiation between the energy storage power supply 100 and the external power supply 300. This communication protocol determines the appropriate power for the external power supply 300 to charge the energy storage power supply 100, achieving efficient and rapid charging between devices and avoiding damage to devices caused by mismatches between the external power supply 300 and the energy storage power supply 100. For example, the communication protocol specifies that the energy storage power supply 100 can support charging powers of 30W, 45W, 60W, and 90W. When the external power supply 300 is connected to the energy storage power supply 100, if the power of the external power supply 300 is greater than 90W, after mutual communication, the external power supply 300 outputs 90W of power to charge the energy storage power supply 100. If the power of the external power supply 300 is between 45W and 60W (excluding 45W and 60W), after mutual communication, the external power supply 300 outputs 45W of power to charge the energy storage power supply 100.

[0049] The communication connection between the protocol IC detection circuit 51 and the Type-C port 10 can be a wired connection or a wireless connection. In the case where the protocol IC detection circuit 51 and the Type-C port 10 are wired, the protocol IC detection circuit 51 and the Type-C port 10 are conductively connected to achieve mutual communication. At this time, the communication between the protocol IC detection circuit 51 and the Type-C port 10 can avoid external interference. In the case where the protocol IC detection circuit 51 and the Type-C port 10 are wirelessly connected, the protocol IC detection circuit 51 and the Type-C port 10 communicate with each other through electromagnetic waves. At this time, the communication between the protocol IC detection circuit 51 and the Type-C port 10 is more convenient.

[0050] Referring to FIG. 4 and FIG. 11 , in some embodiments, a first end of the protocol IC detection circuit 51 is electrically connected to a first pin (Configuration Channel, CC1) 11 of the Type-C port 10, and a second end of the protocol IC detection circuit 51 is electrically connected to a second pin (Configuration Channel, CC2) 13 of the Type-C port 10. 041: Detecting whether a communication protocol exists between the energy storage power supply 100 and the external power supply 300 includes:

[0051] 0411: Detecting the electrical signals of the first pin 11 and the second pin 13; and

[0052] 0413: When the electrical signals of the first pin 11 and the second pin 13 are both square wave signals, it is determined that a communication protocol exists between the energy storage power supply 100 and the external power supply 300.

[0053] 11 , in some embodiments, a first end of the protocol IC detection circuit 51 is electrically connected to the first pin 11 of the Type-C port 10, and a second end of the protocol IC detection circuit 51 is electrically connected to the second pin 13 of the Type-C port 10. The protocol IC detection circuit 51 is configured to: detect electrical signals at the first pin 11 and the second pin 13; and, when the electrical signals at the first pin 11 and the second pin 13 are both square wave signals, determine that a communication protocol exists between the energy storage power supply 100 and the external power supply 300.

[0054] Specifically, the first pin 11 and the second pin 13 are used to enable communication between the energy storage power supply 100 and the external power supply 300. When the energy storage power supply 100 and the external power supply 300 are communicating with each other, both the first pin 11 and the second pin 13 generate square wave signals, thereby confirming that a communication protocol exists between the energy storage power supply 100 and the external power supply 300, and further determining that the charging type of the external power supply 300 is communication protocol charging.

[0055] When the energy storage power supply 100 and the external power supply 300 are charging using a communication protocol, the external power supply 300 initiates a communication negotiation with the energy storage power supply 100 via the first pin 11 and the second pin 13, informing the energy storage power supply 100 of the power types supported by the external power supply 300. After receiving the information via the first pin 11 and the second pin 13, the energy storage power supply 100 analyzes and selects an appropriate power type and sends it to the external power supply 300. The external power supply 300 then receives the information and outputs the corresponding power type.

[0056] Please refer to FIG5 . In some embodiments, 04: detecting the charging type of the external power supply 300 connected to the Type-C port 10 includes: 041: detecting whether a communication protocol exists between the energy storage power supply 100 and the external power supply 300; and

[0057] 045: In the absence of a communication protocol between the energy storage power supply 100 and the external power supply 300, if the open-circuit voltage of the Type-C port 10 is within a preset first voltage range, it is determined that the charging type of the external power supply connected to the Type-C port is solar charging; if the open-circuit voltage of the Type-C port exceeds the first voltage range, and there is a situation where the open-circuit voltage changes when the input current of the battery module 30 changes, it is determined that the charging type of the external power supply 300 connected to the Type-C port 10 is solar charging.

[0058] In conjunction with Figures 10 and 11 , in certain embodiments, the protocol IC detection circuit 51 is further configured to: determine, when no communication protocol exists between the energy storage power supply 100 and the external power supply 300, that the charging type of the external power supply 300 connected to the Type-C port 10 is not communication protocol charging; and the charging type detection module 50 further includes: a resistor voltage divider detection circuit 53, a first end of the resistor voltage divider detection circuit 53 being electrically connected to the Type-C port 10, and a second end of the resistor voltage divider detection circuit 53 being electrically connected to the control module 70. When no communication protocol exists between the energy storage power supply 100 and the external power supply 300, the resistor voltage divider detection circuit 53 is configured to: detect the open-circuit voltage of the Type-C port 10, and if the open-circuit voltage of the Type-C port 10 is within a preset first voltage range, determine that the charging type of the external power supply 300 connected to the Type-C port 10 is solar charging. If the open-circuit voltage of the Type-C port 10 exceeds the first voltage range, and when the input current of the battery module 30 changes, the open-circuit voltage also changes, it is determined that the charging type of the external power supply 300 connected to the Type-C port 10 is solar charging.

[0059] Among them, the resistor voltage divider detection circuit 53 is a structure for detecting the voltage of the circuit, and the resistor voltage divider detection circuit 53 is composed of two resistors in series. The resistor voltage divider detection circuit 53 of the present application is composed of R20 and R22 in series. When it is determined that the charging type of the external power supply 300 is not communication protocol charging, the resistor voltage divider detection circuit 53 is used to detect the open circuit voltage of the Type-C port 10. The preset first voltage range of the present application is [17V, 27V]. If the resistor voltage divider detection circuit 53 detects that the open circuit voltage of the Type-C port 10 is within the range of [17V, 27V], it is determined that the charging type of the external power supply 300 connected to the Type-C port 10 is solar charging. If the open circuit voltage of the Type-C port 10 exceeds the first voltage range, that is, the open circuit voltage of the Type-C port 10 is less than 17V or greater than 27V, then it means that the charging type of the external power supply 300 connected to the Type-C port 10 may be solar charging or not solar charging. To further determine whether solar charging is being used, the input current of the battery module 30 can be controlled and varied. If the open-circuit voltage changes with the input current of the battery module 30, it indicates that solar charging is likely being used on a cloudy day. For example, the control module 70 controls the input current of the battery module 30 to increase. If the open-circuit voltage decreases significantly, the external power supply 300 connected to the Type-C port 10 is determined to be solar charging. At this point, the control module 70 controls the energy storage power supply 100 to activate the corresponding solar charging mode, so that the external power supply 300 charges the battery module 30 in the energy storage power supply 100 in solar charging mode.

[0060] In addition, referring to FIG6 , in some embodiments, 041: detecting whether a communication protocol exists between the energy storage power supply 100 and the external power supply 300 further includes:

[0061] 0415: When at least one of the electrical signals of the first pin 11 and the second pin 13 is not a square wave signal, it is determined that no communication protocol exists between the energy storage power supply 100 and the external power supply 300.

[0062] Please refer to FIG7 . In some embodiments, 04: detecting the charging type of the external power supply 300 connected to the Type-C port 10 includes: 041: detecting whether a communication protocol exists between the energy storage power supply 100 and the external power supply 300; and

[0063] 047: In the absence of a communication protocol between the energy storage power supply 100 and the external power supply 300, if the open-circuit voltage of the Type-C port 10 is within a preset second voltage range, and there is a situation where the open-circuit voltage remains unchanged when the input current of the battery module 30 changes, it is determined that the charging type of the external power supply 300 connected to the Type-C port 10 is vehicle charging.

[0064] In conjunction with Figures 10 and 11, in some embodiments, the protocol IC detection circuit 51 is further configured to: when no communication protocol exists between the energy storage power supply 100 and the external power supply 300, determine that the charging type of the external power supply 300 connected to the Type-C port 10 is not communication protocol charging; the charging type detection module 50 also includes a resistor voltage divider detection circuit 53, a first end of the resistor voltage divider detection circuit 53 is electrically connected to the Type-C port 10, and a second end of the resistor voltage divider detection circuit 53 is electrically connected to the control module 70. When no communication protocol exists between the energy storage power supply 100 and the external power supply 300, the resistor voltage divider detection circuit 53 is configured to: detect the open circuit voltage of the Type-C port 10. If the open circuit voltage of the Type-C port 10 is within a preset second voltage range and there is a situation where the open circuit voltage remains unchanged when the input current of the battery module 30 changes, it is determined that the charging type of the external power supply 300 connected to the Type-C port 10 is vehicle charging.

[0065] Wherein, the second voltage range is different from the first voltage range. In other words, the second voltage range does not intersect with the first voltage range. In the present application, the second voltage range is smaller than the first voltage range. The resistor voltage divider detection circuit 53 of the present application is used to detect the open circuit voltage of the Type-C port 10 when it is determined that the charging type of the external power supply 300 is not communication protocol charging. The preset second voltage range of the present application is [10V, 17V). If the resistor voltage divider detection circuit 53 detects that the open circuit voltage of the Type-C port 10 is within the range of [10V, 17V), then the control module 70 controls the change of the input current of the battery module 30. For example, the control module 70 controls to increase the input current of the battery module 30. If the open circuit voltage hardly changes, it is determined that the charging type of the external power supply 300 connected to the Type-C port 10 is vehicle charging. At this time, the control module 70 controls the energy storage power supply 100 to start the corresponding vehicle charging mode so that the external power supply 300 charges the battery module 30 in the energy storage power supply 100 in the vehicle charging mode.

[0066] Referring to FIG8 , in some embodiments, 06: controlling the energy storage power supply 100 to start a charging mode corresponding to the charging type of the external power supply 300 so that the external power supply 300 charges the battery module 30 in the energy storage power supply 100 in the charging mode includes:

[0071] 069: When the first power supply circuit in the adapter 301 is turned on, the battery module 30 is controlled to be charged according to the charging power of the battery module 30.

[0072] Referring to Figures 10 and 11 , in certain embodiments, the control module 70 includes a battery management module 71 electrically connected to the battery module 30, a main control processor 73, and a buck-boost control circuit 75. The battery management module 71 is configured to determine the charging power of the battery module 30 based on the voltage of the battery module 30. The main control processor 73 is electrically connected to the battery management module 71 and configured to determine whether the energy storage power supply 100 is abnormal and obtain the charging power of the battery module 30 from the battery management module 71. The buck-boost control circuit 75 is electrically connected to the main control processor 73 and electrically connected to the Type-C port 10 via the switch unit 90. The main control processor 73 is further configured to transmit a charge start command to the protocol IC detection circuit 51 and transmit the charging power of the battery module 30 to the buck-boost control circuit 75 when the energy storage power supply 100 is normal. The protocol IC detection circuit 51 is further configured to output a first control signal in response to a charge start command. The first control signal is used to turn on a first power supply circuit in the adapter 301 that is electrically connected to the Type-C port 10. The buck-boost control circuit 75 is configured to control the switch unit 90 to turn on upon receiving the charging power from the battery module 30, and to step up and / or step down the voltage to control charging of the battery module 30 according to the charging power of the battery module 30.

[0073] Specifically, the battery management system (BMS) 71 monitors and manages the battery module 30. The BMS 71 controls the charging and discharging of the battery module 30 by collecting and calculating parameters such as voltage, current, and temperature. For example, the BMS 71 determines the charging power of the battery module 30 by collecting and calculating the voltage of the battery module 30.

[0074] The main control processor 73 is used to issue instructions to control the operation of other components. In one embodiment, the main control processor 73 can be a microcontroller unit (MCU). In another embodiment, the main control processor 73 can be a central processing unit (CPU). The main control processor 73 of the embodiment of the present application adopts an MCU. When the main control processor 73 determines that there is no abnormality in the energy storage power supply 100, it communicates with the battery management module 71 and obtains the charging power signal of the battery module 30. Among them, the abnormality of the energy storage power supply 100 includes no communication between the main control processor 73 and the BMS, abnormal communication between the main control processor 73 and the BMS, BMS voltage imbalance, or abnormality of other components inside the energy storage power supply 100.

[0075] After receiving the charging power signal from the battery module 30, the main control processor 73 sends a start charging command to the protocol IC detection circuit 51. The protocol IC detection circuit 51 outputs a first control signal. After receiving the first control signal, the adapter 301 turns on the first power supply circuit connected to the Type-C port 10. The "first control signal" here can be a high-level signal or a low-level signal. In the embodiment of the present application, the "first control signal" here is a high-level signal. Furthermore, a resistor R37 can be set between the protocol IC detection circuit 51 and the Type-C port 10. When the protocol IC detection circuit 51 outputs a high level, the resistor R37 is used to limit the current and protect the Type-C port 10.

[0076] The main control processor 73 is also configured to transmit the charging power of the battery module 30 to the buck-boost control circuit 75. Upon receiving the charging power of the battery module 30 transmitted from the main control processor 73, the buck-boost control circuit 75 opens the switch unit 90 to conduct the charging circuit of the energy storage power supply 100. This, combined with the conduction of the first power supply circuit in the adapter 301, enables the external power supply 300 to begin charging the energy storage power supply 100. Simultaneously, the buck-boost control circuit 75 is configured to adapt the power transmitted from the external power supply 300 to the required charging power of the battery module 30 of the energy storage power supply 100 (by stepping up and / or stepping down the voltage), thereby charging the battery module 30 of the energy storage power supply 100. For example, if the required charging power of the battery module 30 is 30W and the power transmitted from the external power supply 300 to the energy storage power supply 100 is 80W, the buck-boost control circuit 75 is configured to reduce the 80W power to 30W to charge the battery module 30.

[0077] The external power supply 300 connected to the Type-C port 10 is of the communication protocol charging type, and the buck-boost control circuit 75 boosts and / or reduces the voltage according to the communication protocol charging mode corresponding to the communication protocol charging type, so that the external power supply 300 charges the battery module 30 in the energy storage power supply 100 in the communication protocol charging mode.

[0078] The external power supply 300 connected to the Type-C port 10 is of solar charging type. The maximum power point tracking (MPPT) unit in the buck-boost control circuit 75 can detect the power generation voltage of the solar panel in real time and track the highest voltage and current value, so that the external power supply 300 can output electrical energy at maximum power. At the same time, the buck-boost control circuit 75 also boosts and / or reduces the voltage according to the solar charging mode corresponding to the solar charging type, so that the external power supply 300 can charge the battery module 30 in the energy storage power supply 100 in the solar charging mode. It should be noted that the MPPT unit can be integrated in the buck-boost control circuit 75, or it can be set separately from the buck-boost control circuit 75, which is not limited here.

[0079] The external power supply connected to the Type-C port 10 is a vehicle charging type, and the buck-boost control circuit 75 boosts and / or reduces the voltage according to the vehicle charging mode corresponding to the vehicle charging type, so that the external power supply 300 charges the battery module 30 in the energy storage power supply 100 in the vehicle charging mode.

[0080] The switch unit 90 is a component used to open or close a circuit. When the main control processor 73 determines that the external power source 300 is capable of charging the energy storage power source 100, the buck-boost control circuit 75 controls the switch unit 90 to conduct, thereby enabling the charging circuit. When the main control processor 73 determines that the external power source 300 is unable to charge the energy storage power source 100, the buck-boost control circuit 75 controls the switch unit 90 to be turned off, thereby disconnecting the charging circuit. The switch unit 90 can be a transistor or a field-effect transistor (MOS). When the switch unit 90 is a transistor, the cost of the switch unit 90 is relatively low. When the switch unit 90 is a MOS transistor, the switch unit 90 can serve as a power switch for high-current circuits.

[0081] Referring to FIG. 9 , in certain embodiments, the control method includes:

[0082] 02: When voltage is detected on Type-C port 10, it is determined that an external power supply 300 is connected to Type-C port 10.

[0083] 10 and 11 , in some embodiments, the resistor voltage divider detection circuit 53 is configured to determine that an external power source 300 is connected to the Type-C port 10 when voltage is detected on the Type-C port 10 .

[0084] When it is determined that the external power supply 300 is connected to the Type-C port 10, the charging type detection module 50 starts to detect the charging type of the external power supply 300, and the control module 70 starts to control the energy storage power supply 100 to start the corresponding charging mode, so that the external power supply 300 charges the energy storage power supply 100.

[0085] Referring to Figure 10 , an energy storage system 1000 according to an embodiment of the present application includes an external power supply 300 and an energy storage power supply 100 according to any of the above embodiments. The external power supply 300 is used to charge the energy storage power supply 100. The external power supply 300 can be a solar power generation module 500, a vehicle charger, or other power supply equipment capable of PD charging.

[0086] The energy storage system 1000 of the embodiment of the present application is provided with a charging type detection module 50 and a control module 70. When an external power source 300 is connected to the energy storage power source 100, the energy storage power source 100 can detect the charging type of the external power source 300, thereby enabling the energy storage power source 100 to activate the corresponding charging mode, so that the external power source 300 can charge the energy storage power source 100. Compared with existing energy storage power sources, the energy storage power source 100 of the present application has a single Type-C port 10 that can support multiple charging modes, has a smaller number of charging ports, simplifies the circuit design, and can save circuit material costs.

[0087] Referring to Figure 12, the energy storage system 1000 of the embodiment of the present application includes a solar power generation module 500 and an energy storage power supply 100. The solar power generation module 500 is configured to convert solar energy into electrical energy. The energy storage power supply 100 includes a Type-C port 10, a battery module 30, and a control module 70 electrically connected to the battery module 30. The Type-C port 10 is configured to be electrically connected to the solar power generation module 500. The battery module 30 is configured to store the electrical energy charged by the solar power generation module 500 to the energy storage power supply 100. The control module 70 is configured to control the energy storage power supply 100 to start the solar charging mode, so that the solar power generation module 500 charges the battery module 30 in the solar charging mode.

[0088] Specifically, the energy storage power supply 100 is a structure used to store electrical energy and charge other electrical devices. For example, the energy storage power supply 100 can be used to charge cooking equipment, lighting equipment, or electric vehicles. A Type-C port 10 is located within the energy storage power supply 100, with one end protruding from the power supply 100. This port is used for electrical connection to other components. When the other component is an external power supply 300, the external power supply 300 can be connected to the Type-C port 10 to charge the energy storage power supply 100. When the other component is a load, the load can be connected to the Type-C port 10 to enable the energy storage power supply 100 to charge the load. The battery module 30 is used to store the electrical energy charged by the solar power generation module 500 to the energy storage power supply 100. Furthermore, when the energy storage power supply 100 is charging other electrical devices, the battery module 30 is used to release the stored energy to provide power to the other devices. The battery module 30 may include one or more battery cells, which may be prismatic or cylindrical.

[0089] After receiving the signal indicating that the Type-C port 10 is electrically connected to the solar power generation module 500 , the control module 70 controls the energy storage power supply 100 to start the solar charging mode, so that the solar power generation module 500 can charge the energy storage power supply 100 .

[0090] Referring to Figures 12 and 13 , in some embodiments, the energy storage power supply 100 further includes a charging type detection module 50 electrically connected to the Type-C port 10. The charging type detection module 50 is configured to, when an external power source is connected to the Type-C port 10, detect the charging type of the connected external power source. A control module 70 is electrically connected to the charging type detection module 50. If the charging type detection module 50 detects that the external power source is charging in a solar charging mode, the control module 70 is configured to control the energy storage power supply 100 to activate a solar charging mode, thereby enabling the solar power generation module 500 to charge the battery module 30 in the solar charging mode. Specifically, after the Type-C port 10 is electrically connected to the external power source, an electrical signal from the external power source enters the charging type detection module 50 through the Type-C port 10, and the charging type detection module 50 detects the charging type of the external power source. After the charging type detection module 50 determines that the external power source is the solar power generation module 500, the charging type detection module 50 transmits a signal to the control module 70, and the control module 70 controls the energy storage power supply 100 to start the solar charging mode, so that the solar power generation module 500 can charge the energy storage power supply 100.

[0091] The energy storage power supply 100 of the present application is identical to the energy storage power supply 100 in the above embodiment, and the explanation is the same as before, and will not be described in detail here.

[0092] Referring to Figure 14 , in certain embodiments, a solar power generation module 500 includes a solar panel 501 and an adapter 503. The adapter 503 includes an input circuit 5031, a voltage and current limiting circuit 5033, an output circuit 5035, a first switch circuit 5037, and a second switch circuit 5039. The input circuit 5031 is configured to receive electrical energy from the solar panel 501. The voltage and current limiting circuit 5033 is configured to convert the electrical energy received by the solar panel 501 into a current output with a limited voltage. The output circuit 5035 is electrically connected to a Type-C port and is also configured to receive external control signals. The first switch circuit 5037 is configured to enable or disable the current output from the voltage and current limiting circuit 5033 to the output circuit 5035 based on the control signal. The second switch circuit 5039 is configured to enable or disable the current output from the input circuit 5031 to the output circuit 5035 based on the control signal.

[0093] Referring to Figures 14 and 15 , in certain embodiments, the control signal includes a first control signal transmitted by the control module to the output circuit 5035 via the Type-C port. When the output circuit 5035 receives the first control signal, the first switch circuit 5037 disables the current output from the voltage and current limiting circuit 5033 to the output circuit 5035, and the second switch circuit 5039 enables the current output from the input circuit 5031 to the output circuit 5035. When the output circuit 5035 receives the first control signal, the first power supply circuit of the adapter 503 is turned on, allowing the solar panel 501 to charge the energy storage power supply 100. The first power supply circuit comprises the input circuit 5031, the second switch circuit 5039, and the output circuit 5035. When the second switch circuit 5039 turns on the input circuit 5031 and the output circuit 5035, the solar panel 501 can output a high current through the adapter 503 to charge the energy storage power supply 100, thereby enabling the energy storage power supply 100 to be charged quickly and at high power.

[0094] Please refer to Figures 14 and 15. In some embodiments, the control signal includes a second control signal transmitted by the electronic device to the output circuit 5035 through the Type-C port; when the output circuit 5035 receives the second control signal, the first switch circuit 5037 turns on the voltage and current limiting circuit 5033 to output current to the output circuit 5035, and the second switch circuit 5039 turns off the current output of the input circuit 5031 to the output circuit 5035.

[0095] Among them, the "second control signal" here can be a low-level signal or a high-level signal. In the implementation mode of the present application, the "second control signal" here is a low-level signal, and the first control signal of the present application is different from the second control signal. The "electronic device" here can be a product that uses low-power charging, such as a mobile phone, a computer, a PAD, or headphones. After the adapter 503 receives the second control signal, the second power supply circuit inside the adapter 503 is turned on to output a smaller current to charge the electronic device. The second power supply circuit is composed of an input circuit 5031, a voltage and current limiting circuit 5033, a first switching circuit 5037 and an output circuit 5035. After the adapter 503 is electrically connected to an electronic device requiring low-power charging, the electronic device transmits a second control signal to the output circuit 5035 via the Type-C port. Upon receiving the second control signal, the first switch circuit 5037 activates the voltage and current limiting circuit 5033 to output current to the output circuit 5035, while the second switch circuit 5039 shuts off the current output from the input circuit 5031 to the output circuit 5035. This disconnects the first power supply circuit and turns on the second power supply circuit to charge the electronic device. In this way, different control signals control different power supply circuits to power external devices, providing strong adaptability. This not only ensures the charging efficiency of energy storage power supplies requiring high-power charging, but also prevents damage to electronic devices requiring low-power charging from being impacted by high current.
