Thus, a feature qualified by "first" or "second" can explicitly or implicitly include one or more of said features. In the description of the embodiments of the present application, "plurality" means two or more than two, unless specifically limited otherwise.

[0015] As the use of energy storage devices becomes more widespread, the methods for charging them are becoming more diverse. Currently, methods for charging energy storage devices include AC charging, communication protocol charging, solar charging, and in-vehicle charging. However, conventional energy storage devices require charging ports to accommodate different charging methods, resulting in a large number of charging ports, complex circuit design, and high circuit material costs. To address this issue, the present application provides a method for controlling an energy storage device (shown in FIG. 1), an energy storage device 100 (shown in FIG. 2 or FIG. 10), and an energy storage system 1000 (shown in FIGS. 2 and 10).

[0016] 1 shows a control method for a storage power source according to an embodiment of the present application. Referring to FIG. 2, a storage power source 100 is provided with a Type-C port 10, and the Type-C port 10 is configured to be electrically connected to an external power source 300. The control method includes: Step 04: when the external power source 300 is connected to the Type-C port 10, detecting a 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 in-vehicle charging; and step 06 of controlling the storage power source 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 storage power source 100 in the corresponding charging mode.

[0017] 2 , the storage power supply 100 of the present embodiment 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 power for charging the storage power supply 100 from the external power source 300. The charging type detection module 50 is configured to detect the charging type of the connected external power source 300 when the external power source 300 is connected to the Type-C port 10, where the charging type includes at least one of solar charging, communication protocol charging, and in-vehicle charging. The control module 70 is configured to control the storage power supply 100 to activate a charging mode corresponding to the charging type of the external power source 300, and the external power source 300 charges the battery module 30 in the corresponding charging mode.

[0018] Specifically, the storage power source 100 has a structure for storing power and charging other electrical devices, and for example, the storage power source 100 can be used to charge devices such as cooking appliances, lighting appliances, electric vehicles, etc. The external power source 300 has a structure for charging the storage power source 100, and for example, the external power source 300 may be a solar power generation module 500 or a car charging source, etc.

[0019] The Type-C port 10 is provided inside the storage power source 100, with one end exposed from the storage power source 100, and is used to electrically connect to another element. If the other element is an external power source 300, the external power source 300 can be connected to the Type-C port 10 to charge the storage power source 100, and if the other element is a load, the load can be connected to the Type-C port 10 to enable the storage power source 100 to charge the load.

[0020] The battery module 30 is used to store power that the external power source 300 charges the storage power source 100. When the storage power source 100 charges another electrical device, the battery module 30 is used to discharge the stored power to provide power to the other electrical device. The battery module 30 may include one or more battery cells, and the battery cells may be prismatic or cylindrical.

[0021] After the Type-C port 10 is electrically connected to the external power source 300, the electrical signal of the external power source 300 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 300. After the charging type detection module 50 determines the charging type of the external power source 300, the charging type detection module 50 transmits a signal to the control module 70, which controls the storage power source 100 to activate a corresponding charging mode, so that the charging mode of the storage power source 100 corresponds to the charging type of the connected external power source 300, and the external power source 300 can charge the storage power source 100.

[0022] The charging type refers to the charging method of the external power source 300, and the charging types in this application include solar charging, in-vehicle charging, and communication protocol charging. Solar charging can be performed by connecting to the Type-C port 10 of the storage power source 100 via a solar panel, and the solar panel is used to charge the storage power source 100 by converting sunlight into electricity. In-vehicle charging can be performed by connecting to the Type-C port 10 of the storage power source 100 via an in-vehicle charging adapter, and the in-vehicle battery charges the storage power source 100. Communication protocol charging can establish a charging protocol between the storage power source 100 and the external power source 300, thereby enabling the external power source 300 to charge the storage power source 100. In this application, communication protocol charging is Power Delivery (PD) charging, a charging method that complies with the fast charging standard.

[0023] The charging mode of the storage power source 100 of the present application includes three modes, which correspond to three charging types: solar charging, on-board charging, and communication protocol charging, i.e., solar charging mode, on-board charging mode, and communication protocol charging mode, respectively. When the charging type of the external power source 300 is solar charging, the storage power source 100 activates the corresponding solar charging mode, and the external power source 300 can charge the battery module 30 of the storage power source 100 in the solar charging mode. When the charging type of the external power source 300 is on-board charging, the storage power source 100 activates the corresponding on-board charging mode, and the external power source 300 can charge the battery module 30 of the storage power source 100 in the on-board charging mode. When the charging type of the external power source 300 is communication protocol charging, the storage power source 100 activates the corresponding communication protocol charging mode, and the external power source 300 can charge the battery module 30 of the storage power source 100 in the communication protocol charging mode.

[0024] The storage power supply control method and storage power supply 100 of the present embodiment include a charging type detection module 50 and a control module 70, so that when an external power source 300 is connected to the storage power supply 100, the storage power supply 100 can detect the charging type of the external power source 300, and thereby activate the corresponding charging mode so that the external power source 300 can charge the storage power supply 100. Compared with conventional storage power supplies, one Type-C port 10 in the storage power supply 100 of the present application can support multiple charging methods, which reduces the number of charging ports, simplifies the circuit design, and saves on circuit material costs.

[0025] Referring to FIG. 3 , in some embodiments, step 04 of detecting the charging type of the external power source 300 connected to the Type-C port 10 includes step 041 of detecting whether a communication protocol exists between the storage power source 100 and the external power source 300, and step 043 of determining that the charging type of the external power source 300 connected to the Type-C port 10 is communication protocol charging if a communication protocol exists between the storage power source 100 and the external power source 300.

[0026] 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 and configured to detect whether a communication protocol exists between the storage power source 100 and the external power source 300, and if a communication protocol exists between the storage power source 100 and the external power source 300, determine that the charging type of the external power source 300 connected to the Type-C port 10 is communication protocol charging.

[0027] Specifically, after the Type-C port 10 is electrically connected to the external power source 300, the protocol IC detection circuit 51 is used to recognize whether a communication protocol exists between the storage power source 100 and the external power source 300. If no communication protocol exists between the storage power source 100 and the external power source 300, the protocol IC detection circuit 51 determines that the charging type of the external power source 300 is not communication protocol charging. If a communication protocol exists between the storage power source 100 and the external power source 300, the protocol IC detection circuit 51 determines that the charging type of the external power source 300 is communication protocol charging. At this time, the control module 70 controls the storage power source 100 to activate a corresponding communication protocol charging mode, so that the external power source 300 charges the battery module 30 in the storage power source 100 in the communication protocol charging mode.

[0028] The communication protocol refers to a protocol established through mutual consultation during communication between the storage power source 100 and the external power source 300, and this communication protocol determines the appropriate power that the external power source 300 will charge the storage power source 100, thereby realizing efficient and fast charging between devices and preventing damage to devices due to mismatch between the external power source 300 and the storage power source 100. For example, this communication protocol specifies that the storage power source 100 can support charging powers of 30 W, 45 W, 60 W, and 90 W. When the external power source 300 is connected to the storage power source 100, if the power of the external power source 300 is greater than 90 W, after mutual communication, the external power source 300 outputs 90 W of power to charge the storage power source 100, and if the power of the external power source 300 is a value between 45 W and 60 W (excluding 45 W and 60 W), after mutual communication, the external power source 300 outputs 45 W of power to charge the storage power source 100.

[0029] The communication connection between the protocol IC detection circuit 51 and the Type-C port 10 may be a wired connection or a wireless connection. When the protocol IC detection circuit 51 and the Type-C port 10 are connected by a wire, the protocol IC detection circuit 51 and the Type-C port 10 communicate with each other through a conductive communication connection. In this case, external interference can be avoided in the communication between the protocol IC detection circuit 51 and the Type-C port 10. When the protocol IC detection circuit 51 and the Type-C port 10 are connected by a wireless connection, the protocol IC detection circuit 51 and the Type-C port 10 communicate with each other through electromagnetic waves. In this case, communication between the protocol IC detection circuit 51 and the Type-C port 10 is more convenient.

[0030] 4 and 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, and step 041 of detecting whether a communication protocol exists between the storage power source 100 and the external power source 300 includes step 0411 of detecting electrical signals on the first pin 11 and the second pin 13, and step 0413 of determining that a communication protocol exists between the storage power source 100 and the external power source 300 if the electrical signals on the first pin 11 and the second pin 13 are both square wave signals.

[0031] Referring to FIG. 11 , in some embodiments, a first end of the protocol IC detection circuit 51 is electrically connected to a first pin 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 13 of the Type-C port 10, and the protocol IC detection circuit 51 is configured to detect electrical signals on the first pin 11 and the second pin 13, and if the electrical signals on the first pin 11 and the second pin 13 are both square wave signals, a communication protocol exists between the storage power source 100 and the external power source 300.

[0032] Specifically, the first pin 11 and the second pin 13 are used to realize intercommunication between the storage power source 100 and the external power source 300. When the storage power source 100 and the external power source 300 communicate with each other, the first pin 11 and the second pin 13 both generate square wave signals, thereby determining that a communication protocol exists between the storage power source 100 and the external power source 300, and that the charging type of the external power source 300 is communication protocol charging.

[0033] When the communication protocol between the storage power source 100 and the external power source 300 is charging, the external power source 300 initiates communication negotiation with the storage power source 100 through the first pin 11 and the second pin 13, that is, informs the storage power source 100 of the type of power the external power source 300 supports. After receiving the information through the first pin 11 and the second pin 13, the storage power source 100 analyzes and selects one appropriate power and sends it to the external power source 300, and the external power source 300 receives the message and outputs the corresponding power.

[0034] Referring to FIG. 5 , in some embodiments, the step 04 of detecting the charging type of the external power source 300 connected to the Type-C port 10 includes a step 041 of detecting whether a communication protocol exists between the storage power source 100 and the external power source 300; Step 045 includes determining that the charging type of the external power source 300 connected to the Type-C port 10 is solar charging if the open-circuit voltage of the Type-C port 10 is within a predetermined first voltage range when there is no communication protocol between the storage power source 100 and the external power source 300, and determining that the charging type of the external power source 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 the input current of the battery module 30 changes, resulting in a change in the open-circuit voltage.

[0035] 10 and 11 , in some embodiments, the protocol IC detection circuit 51 is further configured to determine that the charging type of the external power source 300 connected to the Type-C port 10 is not communication protocol charging when there is no communication protocol between the storage power source 100 and the external power source 300, and the charging type detection module 50 further includes a resistive voltage divider detection circuit 53, a first end of which is electrically connected to the Type-C port 10 and a second end of which is electrically connected to the control module 70. When there is no communication protocol between the storage power source 100 and the external power source 300, the resistive voltage divider detection circuit 53 is configured to detect the open-circuit voltage of the Type-C port 10, and when the open-circuit voltage of the Type-C port 10 is within a predetermined first voltage range, determine that the charging type of the external power source 300 connected to the Type-C port 10 is solar charging. If the open circuit voltage of the Type-C port exceeds the first voltage range and the input current of the battery module 30 changes, the open circuit voltage also changes, the charging type of the external power source 300 connected to the Type-C port 10 is determined to be solar charging.

[0036] Here, the resistive voltage divider detection circuit 53 is a circuit voltage detection structure and is configured by connecting two resistors in series. In the present application, the resistive voltage divider detection circuit 53 is configured by connecting R20 and R22 in series. When determining that the charging type of the external power supply 300 is not protocol charging, the resistive voltage divider detection circuit 53 is used to detect the open-circuit voltage of the Type-C port 10. In the present application, the first preset voltage range is [17V, 27V]. If the resistive voltage divider detection circuit 53 detects that the open-circuit voltage of the Type-C port 10 is within the [17V, 27V] range, it determines 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, i.e., if the open-circuit voltage of the Type-C port 10 is less than 17V or greater than 27V, the charging type of the external power supply 300 connected to the Type-C port 10 may or may not be solar charging. To further determine whether solar charging is occurring, the input current of the battery module 30 can be controlled to change. If the open-circuit voltage changes with the change in input current of the battery module 30, this indicates a high possibility of solar charging occurring in the dark. For example, the control module 70 controls the input current of the battery module 30 to increase, and if the open-circuit voltage decreases significantly, it determines that the charging type of the external power source 300 connected to the Type-C port 10 is solar charging. At this time, the control module 70 controls the storage power source 100 to activate a corresponding solar charging mode, so that the external power source 300 charges the battery module 30 in the storage power source 100 in solar charging mode.

[0037] Also, referring to FIG. 6, in some embodiments, step 041 of detecting whether a communication protocol exists between the storage power source 100 and the external power source 300 includes step 0415 of determining that no communication protocol exists between the storage power source 100 and the external power source 300 if at least one of the electrical signals on the first pin 11 and the second pin 13 is not a square wave signal.

[0038] Referring to FIG. 7 , in some embodiments, the step 04 of detecting the charging type of the external power source 300 connected to the Type-C port 10 includes a step 041 of detecting whether a communication protocol exists between the storage power source 100 and the external power source 300; If there is no communication protocol between the storage power source 100 and the external power source 300, and the open-circuit voltage of the Type-C port 10 is within the preset second voltage range, and the input current of the battery module 30 changes but the open-circuit voltage does not change, step 047 is included in which it is determined that the charging type of the external power source 300 connected to the Type-C port 10 is on-board charging.

[0039] 10 and 11 , in some embodiments, the protocol IC detection circuit 51 is further configured to determine that the charging type of the external power source 300 connected to the Type-C port 10 is not communication protocol charging when there is no communication protocol between the storage power source 100 and the external power source 300, and the charging type detection module 50 further includes a resistive voltage divider detection circuit 53, a first end of which is electrically connected to the Type-C port 10 and a second end of which is electrically connected to the control module 70, when there is no communication protocol between the storage power source 100 and the external power source 300, the resistive voltage divider detection circuit 53 is configured to detect the open-circuit voltage of the Type-C port 10, and when the open-circuit voltage of the Type-C port 10 is within a predetermined second voltage range and the input current of the battery module 30 changes but the open-circuit voltage remains unchanged, determine that the charging type of the external power source 300 connected to the Type-C port 10 is in-vehicle charging.

[0040] Here, 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. In the present application, the resistive voltage divider detection circuit 53 is used to detect the open-circuit voltage of the Type-C port 10 when determining that the charging type of the external power source 300 is not communication protocol charging. In the present application, the preset second voltage range is [10V, 17V]. When the resistive voltage divider detection circuit 53 detects that the open-circuit voltage of the Type-C port 10 is within the range of [10V, 17V], the control module 70 controls the input current of the battery module 30 to change. For example, the control module 70 controls the input current of the battery module 30 to increase. If the open-circuit voltage remains almost unchanged, the control module 70 determines that the charging type of the external power source 300 connected to the Type-C port 10 is on-board charging. At this time, the control module 70 controls the power storage power source 100 to activate the corresponding on-board charging mode, and the external power source 300 charges the battery module 30 in the power storage power source 100 in the on-board charging mode.

[0041] Referring to FIG. 8 , in some embodiments, step 06 of controlling the storage power source 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 storage power source 100 in an on-board charging mode includes: Step 061: determining the charging power of the battery module 30 based on the voltage of the battery module 30; Step 063: determining whether there is an abnormality in the power storage power source 100 and obtaining the charging power of the battery module 30; If there is no abnormality in the storage power source 100, a step 065 of transmitting a charge start command and charging power for the battery module 30; Step 067: outputting a first control signal to energize a first power supply circuit electrically connected to the Type-C port 10 of the adapter 301 according to the charging start command; and a step 069 of controlling the battery module 30 to charge based on the charging power of the battery module 30 when the first power supply circuit in the adapter 301 is made conductive.

[0042] 10 and 11 , in some embodiments, the control module 70 includes a battery management module 71 electrically connected to the battery module 30, a master 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 master processor 73 is electrically connected to the battery management module 71 and configured to determine whether there is an abnormality in the storage power source 100 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 master processor 73 and electrically connected to the Type-C port 10 via the switch unit 90. The master processor 73 is further configured to transmit a charging 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 there is no abnormality in the storage power source 100. The protocol IC detection circuit 51 is further configured to output a first control signal according to the charging activation command, and the first control signal is used to conduct a first power supply circuit electrically connected to the Type-C port 10 of the adapter 301. The step-up / step-down control circuit 75 is configured to control the conduction of the switch unit 90 after receiving the charging power of the battery module 30, and to control the step-up and / or step-down to charge the battery module 30 based on the charging power of the battery module 30.

[0043] Specifically, the battery management module 71 (Battery Management System, BMS) is a system that monitors and manages the battery module 30. The battery management module 71 collects and calculates parameters such as voltage, current, and temperature to control the charging and discharging process of the battery module 30. For example, the battery management module 71 collects and calculates the voltage of the battery module 30 to determine the charging power of the battery module 30.

[0044] The master processor 73 is used to send commands and control the operation of other elements. In one embodiment, the master processor 73 may be a microcontroller unit (MCU). In another embodiment, the master processor 73 may be a central processor (CPU). The master processor 73 according to the embodiment of the present application may be an MCU. If the master processor 73 determines that there is no abnormality in the storage power source 100, it communicates with the battery management module 71 to obtain the charging power signal of the battery module 30. Abnormalities in the storage power source 100 include no communication between the master processor 73 and the BMS, abnormal communication between the master processor 73 and the BMS, BMS voltage imbalance, or abnormalities in other elements within the storage power source 100.

[0045] After the master processor 73 receives the charging power signal from the battery module 30, the master processor 73 sends a charging start command to the protocol IC detection circuit 51. The protocol IC detection circuit 51 outputs a first control signal. After the adapter 301 receives the first control signal, the first power supply circuit connected to the Type-C port 10 is turned on. The "first control signal" here may be a high-level signal or a low-level signal. In this embodiment, the "first control signal" here is a high-level signal. Furthermore, a resistor R37 may be provided 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 serves to limit and protect the Type-C port 10.

[0046] The master processor 73 is further used to transmit the charging power of the battery module 30 to the step-up / step-down control circuit 75. After the step-up / step-down control circuit 75 receives the charging power of the battery module 30 transmitted from the master processor 73, the step-up / step-down control circuit 75 turns on the switch unit 90 to conduct the charging circuit of the storage power source 100. In combination with the conduction of the first power supply circuit in the adapter 301, the external power source 300 can start charging the storage power source 100. At the same time, the step-up / step-down control circuit 75 adjusts the power transmitted from the external power source 300 to the storage power source 100 to the charging power required for the battery module 30 of the storage power source 100 (achieved by step-up and / or step-down), thereby charging the battery module 30 of the storage power source 100. For example, the charging power required for the battery module 30 is 30 W, and the power transmitted from the external power source 300 to the storage power source 100 is 80 W. In this case, the step-up / step-down control circuit 75 reduces the 80 W power to 30 W and charges the battery module 30.

[0047] When the external power source 300 connected to the Type-C port 10 is of a communication protocol charging type, the step-up / step-down control circuit 75 steps up and / or steps down the voltage according to a communication protocol charging mode corresponding to the communication protocol charging type, and the external power source 300 charges the battery module 30 in the storage power source 100 in the communication protocol charging mode.

[0048] If the external power source 300 connected to the Type-C port 10 is a solar charging type, the maximum power point tracking (MPPT) unit of the buck-boost control circuit 75 detects the voltage generated by the solar panel in real time and tracks the highest voltage and current value, thereby allowing the external power source 300 to output power at maximum power. At the same time, the buck-boost control circuit 75 also boosts and / or lowers the voltage according to a solar charging mode corresponding to the solar charging type, so that the external power source 300 charges the battery module 30 of the energy storage power source 100 in solar charging mode. Note that the MPPT unit may be integrated into the buck-boost control circuit 75 or provided separately from the buck-boost control circuit 75; this is not a limitation.

[0049] If the external power source connected to the Type-C port 10 is an on-board charging type, the step-up / step-down control circuit 75 steps up and / or steps down the voltage according to the on-board charging mode corresponding to the on-board charging type, and the external power source 300 charges the battery module 30 in the storage power source 100 in the on-board charging mode.

[0050] The switch unit 90 is an element for opening and closing the circuit within the circuit. When the master processor 73 determines that the external power source 300 can charge the storage power source 100, the step-up / step-down control circuit 75 controls the conduction of the switch unit 90 to make the charging circuit conductive. When the master processor 73 determines that the external power source 300 cannot charge the storage power source 100, the step-up / step-down control circuit 75 controls the turn-off of the switch unit 90 to disconnect the charging circuit. The switch unit 90 can be made of a transistor or a field-effect transistor (Metal-Oxide-Semiconductor, MOS). When the switch unit 90 is a transistor, the cost of the switch unit 90 is low. When the switch unit 90 is a MOS transistor, the switch unit 90 can be used as a power switch for a large-current circuit.

[0051] Referring to FIG. 9, in some embodiments, the control method includes step 02 of determining that an external power source 300 is connected to the Type-C port 10 if it detects that a voltage is present at the Type-C port 10.

[0053] When it is determined that the external power source 300 is connected to the Type-C port 10, the charging type detection module 50 starts up to detect the charging type of the external power source 300, and the control module 70 starts up to control the storage power source 100 to activate the corresponding charging mode, so that the external power source 300 charges the storage power source 100.

Compared with conventional energy storage power sources, one Type-C port 10 in the energy storage power source 100 according to the present application can support multiple charging methods, which reduces the number of charging ports, simplifies the circuit design, and saves the cost of circuit materials.

[0056] 12 , a power storage system 1000 according to an embodiment of the present application includes a solar power generation module 500 and a power storage power source 100. The solar power generation module 500 is configured to convert sunlight into electric power. The power storage power source 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 electric power that the solar power generation module 500 charges to the power storage power source 100. The control module 70 controls the power storage power source 100 to activate a solar charging mode, and is configured so that the solar power generation module 500 charges the battery module 30 in the solar charging mode.

[0057] Specifically, the storage power source 100 is a structure for storing power and charging other electrical devices. For example, the storage power source 100 can be used to charge devices such as cooking appliances, lighting appliances, and electric vehicles. The Type-C port 10 is provided inside the storage power source 100, with one end exposed from the storage power source 100 and used to electrically connect to other elements. If the other element is an external power source 300, the external power source 300 can be connected to the Type-C port 10 to charge the storage power source 100. If the other element is a load, the load can be connected to the Type-C port 10 to charge the load from the storage power source 100. The battery module 30 is used to store power that the solar power generation module 500 charges the storage power source 100. When the storage power source 100 charges other electrical devices, the battery module 30 is used to discharge the stored power to provide power to the other electrical devices. The battery module 30 may include one or more battery cells, and the battery cells may be prismatic or cylindrical.

[0058] After the control module 70 receives a signal that the Type-C port 10 is electrically connected to the solar power generation module 500, the control module 70 controls the storage power source 100 to activate a solar charging mode, so that the solar power generation module 500 can charge the storage power source 100.

[0059] 12 and 13 , in some embodiments, the storage power source 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 detect the charging type of the connected external power source when the external power source is connected to the Type-C port 10. The control module 70 is electrically connected to the charging type detection module 50 and is configured to control the storage power source 100 to activate a solar charging mode when the charging type detection module 50 detects that the charging type of the external power source is solar charging, so that the solar power generation module 500 charges 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 of the external power source is detected by the charging type detection module 50. 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, which controls the storage power source 100 to activate the solar charging mode, so that the solar power generation module 500 can charge the storage power source 100.

[0060] The storage power source 100 of the present application is completely the same as the storage power source 100 in the above embodiment, and the interpretation is the same as above, so a detailed description will not be given here.

[0061] 14 , in some embodiments, a solar power generation module 500 includes a solar panel 501 and an adapter 503, and the adapter 503 includes an input circuit 5031, a voltage / 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 power from the solar panel 501. The voltage / current limiting circuit 5033 is configured to convert the power received from the solar panel 501 into a current with a limited voltage and output the current. The output circuit 5035 is electrically connected to the Type-C port and is further used to receive a control signal transmitted from the outside. The first switch circuit 5037 is configured to open or close the current output of the voltage / current limiting circuit 5033 to the output circuit 5035 based on the control signal. The second switch circuit 5039 is configured to open or close the current output of the input circuit 5031 to the output circuit 5035 based on the control signal.

[0062] 14 and 15 , in some embodiments, the control signal includes a first control signal transmitted by the control module to the output circuit 5035 through the Type-C port, and when the output circuit 5035 receives the first control signal, the first switch circuit 5037 turns off the current output from the voltage and current limiting circuit 5033 to the output circuit 5035, and the second switch circuit 5039 turns on the current output from the input circuit 5031 to the output circuit 5035. When the output circuit 5035 receives the first control signal, it turns on the first power supply circuit of the adapter 503, causing the solar panel 501 to charge the storage power source 100. The first power supply circuit includes the input circuit 5031, the second switch circuit 5039, and the output circuit 5035. When the second switch circuit 5039 connects the input circuit 5031 and the output circuit 5035, the solar panel 501 can output a large current through the adapter 503 to charge the storage power source 100, thereby allowing the storage power source 100 to be charged quickly with a large amount of power.

[0063] 14 and 15, in some embodiments, the control signal includes a second control signal transmitted by the electronic device to the output circuit 5035 via the Type-C port, and when the output circuit 5035 receives the second control signal, the first switch circuit 5037 turns on the current output of the voltage and current limiting circuit 5033 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.

The "electronic device" here may be a product that requires low power charging, such as a mobile phone, a computer, a PAD, or earphones. After the adapter 503 receives the second control signal, the second power supply circuit inside the adapter 503 is turned on and outputs a small current to charge the electronic device. The second power supply circuit includes an input circuit 5031, a voltage / current limiting circuit 5033, a first switch circuit 5037, and an output circuit 5035. After the adapter 503 is electrically connected to an electronic device that needs to be charged at low power, the electronic device transmits a second control signal to the output circuit 5035 via 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 outputting current to the output circuit 5035, and the second switch circuit 5039 turns off the input circuit 5031 outputting current to the output circuit 5035, i.e., the first power supply circuit is turned off and the second power supply circuit is conductive to charge the electronic device. In this way, different control signals control different power supply circuits to supply power to external devices, which is highly adaptable and can meet the charging efficiency of a storage power source that needs to be charged at high power, while avoiding the problem of damage to electronic devices that are charged at low power due to the impact of a large current.
