Communication protocol charging can reach a charging agreement between the energy storage power supply 100 and the external power supply 300, so that the external power supply 300 can charge the energy storage power supply 100. In this application, communication protocol charging is power delivery (Power Delivery, PD) charging, which is a type of charging that complies with fast charging standards.

The charging mode of the energy storage power supply 100 of this application includes three modes. The three modes 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 respectively. 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 activates 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.

Please refer to Figure 3. 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 there is a communication protocol between the energy storage power supply 100 and the external power supply 300; and

043: If there is a communication protocol 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.

Please combine Figure 10 and Figure 11. In some embodiments, the charging 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. The protocol IC detection circuit 51 is configured as: Detect whether there is a communication protocol between the energy storage power supply 100 and the external power supply 300, and if there is a communication protocol between the energy storage power supply 100 and the external power supply 300, determine the charging type of the external power supply 300 connected to the Type-C port 10 Charge the communication protocol.

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 there is a communication protocol 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 for the communication protocol. When there is a 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 is communication protocol charging. At this time, the control module 70 controls the energy storage power supply 100 to start 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.

The communication protocol refers to an agreement reached through communication and mutual negotiation between the energy storage power supply 100 and the external power supply 300. The communication protocol determines the appropriate power so that the external power supply 300 can charge the energy storage power supply 100 to achieve high efficiency between devices. Fast charging avoids damage to the equipment caused by mismatch between the external power supply 300 and the energy storage power supply 100 . For example, the communication protocol stipulates 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, communication between Finally, the external power supply 300 outputs 90W 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 power to charge the energy storage power supply 100.

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 connected through a communication conductive connection 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. When the protocol IC detection circuit 51 and the Type-C port 10 are connected wirelessly, the protocol IC detection circuit 51 and the Type-C port 10 realize mutual communication through electromagnetic waves. At this time, communication between the protocol IC detection circuit 51 and the Type-C port 10 is more convenient.

Please refer to Figure 4 and Figure 11. In some embodiments, the first end of the protocol IC detection circuit 51 is electrically connected to the first pin (Configuration Channel, CC1) 11 of the Type-C port 10. The protocol IC detection circuit 51 The second end is electrically connected to the second pin (Configuration Channel, CC2) 13 of the Type-C port 10; 041: Detect whether there is a communication protocol between the energy storage power supply 100 and the external power supply 300, including:

0411: Detect the electrical signals of the first pin 11 and the second pin 13; and

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

Please refer to Figure 11. In some embodiments, the first end of the protocol IC detection circuit 51 is electrically connected to the first pin 11 of the Type-C port 10, and the second end of the protocol IC detection circuit 51 is electrically connected to the Type-C port. The second pin 13 of 10 is electrically connected; the protocol IC detection circuit 51 is configured to: detect the electrical signals of the first pin 11 and the second pin 13; and the electrical signals of the first pin 11 and the second pin 13. When the signals are all square wave signals, it is determined that there is a communication protocol between the energy storage power supply 100 and the external power supply 300 .

Specifically, the first pin 11 and the second pin 13 are used to realize mutual 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 communicate with each other, both 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 supply 100 and the external power supply 300 , and further determine that the charging type of the external power supply 300 is communication protocol charging.

When the communication protocol is used for charging between the energy storage power supply 100 and the external power supply 300, the external power supply 300 initiates communication negotiation with the energy storage power supply 100 through the first pin 11 and the second pin 13, that is, informs the energy storage power supply 100, What power types does external power supply 300 support? After receiving the information through the first pin 11 and the second pin 13, the energy storage power supply 100 analyzes and selects a suitable power to send to the external power supply 300. The external power supply 300 receives the message and outputs the corresponding power.

Please refer to Figure 5. 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 there is a communication protocol between the energy storage power supply 100 and the external power supply 300; and

045: When there is no 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 the preset first voltage range, determine the external power supply connected to the Type-C port. The charging type 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, the open circuit voltage also changes, determine whether the Type-C port 10 is connected The charging type of the external power supply 300 is solar charging.

Please combine Figure 10 and Figure 11. In some embodiments, the protocol IC detection circuit 51 is also configured to: when there is no communication protocol between the energy storage power supply 100 and the external power supply 300, determine the Type-C port 10 The charging type of the connected external power supply 300 does not charge for the communication protocol; the charging type detection module 50 also includes: a resistor voltage dividing detection circuit 53. The first end of the resistor voltage dividing detection circuit 53 is electrically connected to the Type-C port 10, and the resistor voltage dividing detection circuit 53 is electrically connected to the Type-C port 10. The second end of the voltage division detection circuit 53 is electrically connected to the control module 70 . When there is no communication protocol between the energy storage power supply 100 and the external power supply 300 , the resistor voltage division 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 the predetermined value. If it is within the first voltage range, 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, and there is a situation where the open circuit voltage also changes when the input current of the battery module 30 changes, determine the charging type of the external power supply 300 connected to the Type-C port 10 Charge solar energy.

Among them, the resistor voltage-dividing detection circuit 53 is a structure used to detect the voltage of the circuit, and the resistor voltage-dividing detection circuit 53 is composed of two resistors connected in series. The resistor voltage-dividing detection circuit 53 of this application is composed of R20 and R22 connected in series. When it is determined that the charging type of the external power supply 300 is not charging for the communication protocol, the resistor voltage-dividing detection circuit 53 is used to detect the open circuit voltage of the Type-C port 10 . The preset first voltage range of this 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 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, at this time, it means that the charging type of the external power supply 300 connected to the Type-C port 10 may It may or may not be solar charging. In order to further determine whether it is solar charging, the input current of the battery module 30 can be controlled to change. If the open circuit voltage changes following the change of the input current of the battery module 30, it means that solar charging is likely to be carried out on a cloudy day. For example, the control module 70 controls to increase the input current of the battery module 30. If the open circuit voltage decreases significantly, it is determined that the charging type of the external power supply 300 connected to the Type-C port 10 is solar charging. At this time, 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 the solar charging mode.

Please refer to Figure 7. 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 there is a communication protocol between the energy storage power supply 100 and the external power supply 300; and

047: When there is no 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 the preset second voltage range, and there is a change in the input current of the battery module 30 , when the open circuit voltage remains unchanged, determine the charging type of the external power supply 300 connected to the Type-C port 10 to be a car charger.

Please combine Figure 10 and Figure 11. In some embodiments, the protocol IC detection circuit 51 is also configured to: when there is no communication protocol between the energy storage power supply 100 and the external power supply 300, determine the Type-C port 10 The charging type of the connected external power supply 300 does not charge for the communication protocol; the charging type detection module 50 also includes a resistor voltage dividing detection circuit 53. The first end of the resistor voltage dividing detection circuit 53 is electrically connected to the Type-C port 10. The second end of the voltage detection circuit 53 is electrically connected to the control module 70. When there is no communication protocol between the energy storage power supply 100 and the external power supply 300, the resistor voltage division detection circuit 53 is configured to: detect the Type-C port 10 If the open circuit voltage of the Type-C port 10 is within the preset second voltage range, and there is a situation where the open circuit voltage does not change when the input current of the battery module 30 changes, it is determined that the Type-C port 10 is connected The charging type of the external power supply 300 is a car charger.

The second voltage range is different from the first voltage range. In other words, there is no intersection between the second voltage range and the first voltage range. In this application, the second voltage range is smaller than the first voltage range. The resistor voltage division 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 charging for the communication protocol. The preset second voltage range of this application is [10V, 17V). If the resistor voltage dividing detection circuit 53 detects that the open circuit voltage of the Type-C port 10 is within the range of [10V, 17V), at this time, the control module 70 controls to change the input current of the battery module 30. For example, the control module 70 controls to increase the battery module. With an input current of 30, if the open circuit voltage has almost no change, it is determined that the charging type of the external power supply 300 connected to the Type-C port 10 is car charging.
