The current charging modes of the energy storage power supply include AC charging, communication protocol charging, solar charging, vehicle charging and the like. However, the current energy storage power supply needs to set corresponding charging ports according to different charging modes, so that the number of the charging ports of the energy storage power supply is large, the circuit design is complex, and the circuit material cost is high. To solve this problem, the present application provides a control method of an energy storage power supply (shown in fig. 1), an energy storage power supply 100 (shown in fig. 2 or 10), and an energy storage system 1000 (shown in fig. 2 and 10).

Referring to fig. 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 electric energy charged from the external power source 300 to the energy storage power source 100. The charge type detection module 50 is configured to: in case that the external power source 300 is connected to the Type-C port 10, a charging Type of the connected external power source 300 is detected, the charging Type including at least one of solar charging, communication protocol charging, and vehicle charging. The control module 70 is configured to: the energy storage power source 100 is controlled to start a charging mode corresponding to the charging type of the external power source 300 such that the external power source 300 charges the battery module 30 in the corresponding charging mode.

Specifically, the energy storage power supply 100 is a structure for storing electric energy and charging other electric appliances, for example, the energy storage power supply 100 may be used for charging devices such as cooking devices, lighting devices, or electric vehicles. The external power source 300 is a structure for charging the energy storage power source 100, and for example, the external power source 300 may be the solar power generation module 500 or a vehicle charging power source, or the like.

The Type-C port 10 is disposed inside the energy storage power supply 100 and one end of the Type-C port is exposed from the energy storage power supply 100, and the Type-C port 10 is used for being electrically connected with other elements. When the other element is the 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 element is a load, the load may 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 electric energy charged from the external power source 300 to the energy storage power source 100. And, when the energy storage power source 100 charges other electric devices, the battery module 30 is used to release the stored electric energy to supply the electric energy to the other electric devices. The battery module 30 may include one or more battery cells, which may be prismatic batteries or cylindrical batteries.

After the Type-C port 10 is electrically connected to the external power supply 300, an electrical signal of the external power supply 300 enters the charge Type detection module 50 through the Type-C port 10, and the charge Type of the external power supply 300 is detected by the charge Type detection module 50. After the charging type detection module 50 determines the charging type of the external power supply 300, 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 a corresponding charging mode, so that the charging mode of the energy storage power supply 100 corresponds to the charging type of the connected external power supply 300, and the external power supply 300 can charge the energy storage power supply 100.

The charging type refers to a charging mode of the external power supply 300, and the charging type of the present application includes solar charging, vehicle charging and communication protocol charging. Solar charging can be connected with the Type-C port 10 of the energy storage power source 100 through a solar panel for converting solar energy into electric energy, thereby charging the energy storage power source 100. The vehicle charging can be connected with the Type-C port 10 of the energy storage power supply 100 through the vehicle charging head so that the vehicle-mounted battery charges the energy storage power supply 100. Communication protocol charging enables charging of the stored energy power supply 100 by the external power supply 300 by enabling a charging protocol between the stored energy power supply 100 and the external power supply 300. In the present application, the communication protocol charging is a Power Delivery (PD) charging, which is a charging that complies with the rapid charging standard.

The charging modes of the energy storage power supply 100 of the present application include three modes, which respectively correspond to three charging types of solar charging, vehicle charging and communication protocol charging, namely a solar charging mode, a vehicle charging mode and a communication protocol charging mode. In case that the charging type of the external power source 300 is solar charging, the energy storage power source 100 starts a corresponding solar charging mode, so that the external power source 300 can charge the battery module 30 in the energy storage power source 100 in the solar charging mode. In case that the charging type of the external power source 300 is a vehicle charging, the energy storage power source 100 starts a corresponding vehicle charging mode, so that the external power source 300 can charge the battery module 30 in the energy storage power source 100 in the vehicle charging mode. In case that the charging type of the external power source 300 is communication protocol charging, the energy storage power source 100 starts a corresponding communication protocol charging mode, so that the external power source 300 can charge the battery module 30 in the energy storage power source 100 in the communication protocol charging mode.

According to the energy storage power supply control method and the energy storage power supply 100, the charging type detection module 50 and the control module 70 are arranged, so that the energy storage power supply 100 can detect the charging type of the external power supply 300 when the external power supply 300 is connected with the energy storage power supply 100, and the energy storage power supply 100 can start a corresponding charging mode, and the external power supply 300 can charge the energy storage power supply 100. Compared with the existing energy storage power supply, one Type-C port 10 in the energy storage power supply 100 can correspond to multiple charging modes, the number of charging ports is small, the circuit design is simple, and the circuit material cost can be saved.

Referring to fig. 3, in some embodiments, 04: detecting the charging Type of the external power supply 300 accessed by 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; a kind of electronic device with high-pressure air-conditioning system

043: in the case where a communication protocol exists between the energy storage power source 100 and the external power source 300, it is determined that the Type of charging of the external power source 300 to which the Type-C port 10 is connected is the communication protocol charging.

Referring to fig. 10 and 11, in some embodiments, the charge Type detection module 50 includes a protocol IC detection circuit 51, the protocol IC detection circuit 51 is communicatively connected to the Type-C port 10, and the protocol IC detection circuit 51 is configured to: detecting whether a communication protocol exists between the energy storage power supply 100 and the external power supply 300, and determining that the charging Type of the external power supply 300 accessed by the Type-C port 10 is the communication protocol charging in the case that the communication protocol exists between the energy storage power supply 100 and the external power supply 300.

Specifically, after the Type-C port 10 is electrically connected to the external power supply 300, the protocol IC detection circuit 51 is configured to identify whether a communication protocol exists between the energy storage power supply 100 and the external power supply 300. In the case where there is no communication protocol 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 does not charge the communication protocol. In the case where 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 the communication protocol charging. At this time, the control module 70 controls the energy storage power source 100 to start a corresponding communication protocol charging mode, so that the external power source 300 charges the battery module 30 in the energy storage power source 100 in the communication protocol charging mode.

The communication protocol refers to a protocol achieved by communication and negotiation between the energy storage power supply 100 and the external power supply 300, and determines appropriate power to enable the external power supply 300 to charge the energy storage power supply 100, so that efficient and rapid charging between devices is achieved, and damage to the devices caused by mismatching between the external power supply 300 and the energy storage power supply 100 is avoided. For example, the communication protocol specifies that the energy storage power supply 100 is capable of supporting charging power of 30W, 45W, 60W, and 90W, and in the case where 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, the external power supply 300 outputs power of 90W to charge the energy storage power supply 100 after communicating with each other; if the power of the external power supply 300 is at a value between 45W and 60W (excluding 45W and 60W), the external power supply 300 outputs 45W power to charge the energy storage power supply 100 after communicating with each other.

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. In the case of a wired connection between the protocol IC detection circuit 51 and the Type-C port 10, the protocol IC detection circuit 51 and the Type-C port 10 are electrically connected through communication to achieve mutual communication. At this time, communication between the protocol IC detection circuit 51 and the Type-C port 10 can avoid external interference. In the case of wireless connection between the protocol IC detection circuit 51 and the Type-C port 10, mutual communication is achieved between the protocol IC detection circuit 51 and the Type-C port 10 by electromagnetic waves. At this time, communication between the protocol IC detection circuit 51 and the Type-C port 10 is more convenient.

Referring to fig. 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, CC 1) 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, CC 2) 13 of the Type-C port 10; 041: detecting whether a communication protocol exists between the stored energy power source 100 and the external power source 300 includes:

0411: detecting the electrical signals of the first pin 11 and the second pin 13; a kind of electronic device with high-pressure air-conditioning system

0413: in the case that the electrical signals of the first pin 11 and the second pin 13 are square wave signals, it is determined that a communication protocol exists between the energy storage power source 100 and the external power source 300.

Referring to fig. 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: detecting the electrical signals of the first pin 11 and the second pin 13; and determining that a communication protocol exists between the energy storage power supply 100 and the external power supply 300 in the case that the electric signals of the first pin 11 and the second pin 13 are square wave signals.

Specifically, the first pin 11 and the second pin 13 are used to enable mutual communication between the energy storage power source 100 and the external power source 300. In the case of the mutual communication between the energy storage power source 100 and the external power source 300, the first pin 11 and the second pin 13 generate square wave signals, thereby confirming the existence of a communication protocol between the energy storage power source 100 and the external power source 300 and further determining the charging type of the external power source 300 as the communication protocol charging.

In case of charging the communication protocol between the energy storage power supply 100 and the external power supply 300, the external power supply 300 initiates a communication negotiation to the energy storage power supply 100 via the first pin 11 and the second pin 13, i.e. informs the energy storage power supply 100 which power types the external power supply 300 supports. After the energy storage power supply 100 receives the information through the first pin 11 and the second pin 13, it analyzes and selects a proper power to send to the external power supply 300, and the external power supply 300 receives the information and outputs the corresponding power.

Referring to fig. 5, in some embodiments, 04: detecting the charging Type of the external power supply 300 accessed by 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; a kind of electronic device with high-pressure air-conditioning system

045: under the condition that a communication protocol does not exist 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, determining 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 when the input current of the battery module 30 changes and the open circuit voltage also changes, it is determined that the charging Type of the external power source 300 connected to the Type-C port 10 is solar charging.

Referring to fig. 10 and 11, in some embodiments, the protocol IC detection circuit 51 is further configured to: in the case that a communication protocol does not exist between the energy storage power supply 100 and the external power supply 300, determining that the charging Type of the external power supply 300 accessed by the Type-C port 10 does not charge the communication protocol; the charge type detection module 50 further includes: the resistor divider detection circuit 53, the first end of the resistor divider detection circuit 53 is electrically connected to the Type-C port 10, and the second end of the resistor divider detection circuit 53 is electrically connected to the control module 70. In the case where there is no communication protocol between the energy storage power supply 100 and the external power supply 300, the resistance voltage division detection circuit 53 is configured to: and detecting 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, determining 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 and the open-circuit voltage also changes, it is determined that the charging Type of the external power source 300 connected to the Type-C port 10 is solar charging.

The resistor-voltage-dividing detection circuit 53 is configured to detect a voltage of the circuit, and the resistor-voltage-dividing detection circuit 53 is configured by connecting two resistors in series. The resistor-voltage-division detecting circuit 53 of the present application is composed of R20 and R22 connected in series, and the resistor-voltage-division detecting circuit 53 is used to detect the open-circuit voltage of the Type-C port 10 in the case where it is determined that the charging Type of the external power supply 300 is not charging for the communication protocol. The preset first voltage range of the present application is [17V,27V ]. If the resistor voltage division 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 to which the Type-C port 10 is connected 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, the charging Type of the external power source 300 connected to the Type-C port 10 may or may not be solar charging. To further determine whether the battery module 30 is being charged, the input current of the battery module 30 may be controlled to be changed, and if the open circuit voltage is changed along with the change of the input current of the battery module 30, it is indicated that the solar charging is likely to be performed on a cloudy day. For example, the control module 70 controls to increase the input current of the battery module 30, and if the open-circuit voltage is significantly reduced, 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 energy storage power source 100 to start a corresponding solar charging mode, so that the external power source 300 charges the battery module 30 in the energy storage power source 100 in the solar charging mode.

Additionally, referring to FIG. 6, in some embodiments, 041: detecting whether a communication protocol exists between the stored energy power source 100 and the external power source 300, further includes:

0415: in case 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 source 100 and the external power source 300.

Referring to fig. 7, in some embodiments, 04: detecting the charging Type of the external power supply 300 accessed by 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; a kind of electronic device with high-pressure air-conditioning system

047: in the case that no communication protocol exists 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 the preset second voltage range, and when the input current of the battery module 30 is changed and the open circuit voltage is unchanged, it is determined that the charging Type of the external power supply 300 to which the Type-C port 10 is connected is vehicle charging.

Referring to fig. 10 and 11, in some embodiments, the protocol IC detection circuit 51 is further configured to: in the case that a communication protocol does not exist between the energy storage power supply 100 and the external power supply 300, determining that the charging Type of the external power supply 300 accessed by the Type-C port 10 does not charge the communication protocol; the charge Type detection module 50 further includes a resistive voltage division detection circuit 53, a first end of the resistive voltage division detection circuit 53 is electrically connected to the Type-C port 10, a second end of the resistive voltage division detection circuit 53 is electrically connected to the control module 70, and in the absence of a communication protocol between the stored energy power supply 100 and the external power supply 300, the resistive voltage division detection circuit 53 is configured to: and detecting 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 second voltage range and the input current of the battery module 30 is changed and the open-circuit voltage is unchanged, determining that the charging Type of the external power supply 300 connected to the Type-C port 10 is vehicle charging.

Wherein the second voltage range is different from the first voltage range, in other words, there is no intersection of the second voltage range with the first voltage range. In the present application, the second voltage range is smaller than the first voltage range. The resistor-voltage-division detecting circuit 53 of the present application is used to detect the open-circuit voltage of the Type-C port 10 in the case where it is determined that the charging Type of the external power supply 300 is not the communication protocol. The preset second voltage range of the present application is [10v,17 v).
