[0064] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0065] In the field of charging and discharging, power supply devices are primarily connected to power sources or electrical loads via connecting cables, enabling the power supply device to provide power to the load, or vice versa. Taking the most common power supply device, the portable power bank, as an example, when a portable power bank supplies power to different types of electrical loads, it needs to be connected to the load using a dedicated connecting cable corresponding to each load. Similarly, when a power source charges a portable power bank, it also needs to be connected to the power source using a dedicated connecting cable. However, these power supply devices present certain safety hazards during operation.

[0066] Based on this, this application provides a power supply device 10, which can solve the safety hazards existing during operation. As shown in FIG1, the power supply device 10 includes: a processing chip 11, an energy storage component 12, and a safety management component 13. The processing chip 11 includes a protocol chip 111 and a main control chip 112. The protocol chip 111 is connected to the main control chip 112. The main control chip 112 is connected to the energy storage component 12 and the safety management component 13, respectively. The energy storage component 12 is connected to the safety management component 13.

[0067] Safety management component 13 is used to monitor power device 10 when energy storage component 12 is in operation mode, and send operation mode status control signal to processing chip 11 when power device 10 malfunctions.

[0068] The main control chip 112 is used to detect whether the power supply device 10 and the target device 30 have completed a physical connection;

[0069] Protocol chip 111 is used to detect whether the power supply device 10 and the target device 30 have completed a communication handshake after determining that a physical connection has been established between the power supply device 10 and the target device 30; and,

[0070] The main control chip 112 is also used to control the operating mode of the energy storage component 12 when it is determined that the power supply device 10 and the target device 30 have successfully communicated and shaken hands, and to control the energy storage component 12 to stop operating mode according to the status control signal sent by the safety management component 13.

[0071] The processing chip 11 in the power supply device 10 can be disposed within the body of the power supply device 10. Optionally, the body of the power supply device 10 serves to fix other components in the power supply device 10. The housing can be made of a thermoplastic plastic material made of polycarbonate and polyacrylonitrile alloy, or it can be made of polycarbonate material. Of course, it can also be made of other materials with high strength, good toughness, high temperature resistance, etc.

[0072] Specifically, the processing chip 11 can be implemented by multiple different functional circuits, or it can be understood as being implemented by at least one of components such as transistors, resistors, and capacitors. In the embodiments of this application, the processing chip 11 can control the operating mode of the energy storage component 12 in the power supply device 10, namely, the charging mode or the discharging mode.

[0073] In this embodiment, the power supply device 10 may be equipped with buttons, controls, or a touchscreen for receiving relevant user input commands. In practical applications, the user can input the operating mode control command of the energy storage component 12 via buttons, controls, or a touchscreen. Correspondingly, the processing chip 11 can respond to the operating mode control command to control the energy storage component 12 in the power supply device 10 to switch the current operating mode to the operating mode carried in the operating mode control command.

[0074] In this embodiment, the processing chip 11 in the power supply device 10 may include a protocol chip 111 and a main control chip 112. Optionally, both the protocol chip 111 and the main control chip 112 can be implemented using at least one of components such as transistors, capacitors, and resistors.

[0075] In one embodiment, the protocol chip 111 in the processing chip 11 is further configured to send a handshake success command to the main control chip 112 when it is determined that the power supply device 10 and the target device 30 have successfully communicated and handshaked, instructing the main control chip 112 to control the energy storage component 12 to be in the operating mode.

[0076] Optionally, after determining that the power supply device 10 and the target device 30 have completed a communication handshake, the protocol chip 111 in the power supply device 10 can generate a handshake success command and send the handshake success command to the main control chip 112 to inform the main control chip 112 that the power supply device 10 and the target device 30 have successfully completed the handshake. Optionally, the communication handshake detection command can be represented by a high-level signal or a low-level signal, or by other specific signals, such as square wave signals, triangular wave signals, harmonic signals, etc.

[0077] The main control chip 112 in the power supply device 10 can be housed within the main body of the power supply device 10. This main control chip 112 can be implemented using multiple different functional circuits, such as analog-to-digital converters or digital-to-analog converters. The analog-to-digital converter is used to convert the analog signals received by the power supply device 10 into digital signals, while the digital-to-analog converter is used to convert the digital signals received by the power supply device 10 into analog signals.

[0078] In this embodiment, the main control chip 112 can be a processing chip 11 with detection and control functions. This main control chip 112 can detect whether the power supply device 10 and the target device 30 have completed a physical connection. A completed physical connection can be understood as the power supply device 10 and the target device 30 being connected via a connecting cable; that is, one end of the connecting cable is connected to the power supply device 10, and the other end is connected to the target device 30. In this embodiment, the main control chip 112 can be implemented using functional chips and resistors.

[0079] In one embodiment, the main control chip 112 in the processing chip 11 is further configured to send a communication handshake detection command to the protocol chip 111 when it is determined that the interface component 14 in the power supply device 10 and the target device 30 have completed a physical connection, instructing the protocol chip 111 to detect whether the power supply device 10 and the target device 30 have completed a communication handshake.

[0080] If the detection result of the main control chip 112 is that the interface component 14 and the target device 30 have completed a physical connection, the main control chip 112 can generate a communication handshake detection command and send the communication handshake detection command to the protocol chip 111 of the power supply device 10, so that the protocol chip 111 responds to the communication handshake detection command and starts to detect whether the power supply device 10 and the target device 30 have completed a communication handshake.

[0081] Specifically, during the operation of the power supply device 10, the main control chip 112 in the power supply device 10 can continuously generate operating mode control commands. After the protocol chip 111 in the power supply device 10 determines that the power supply device 10 and the target device 30 have completed the communication handshake, the main control chip 112 can successfully send the operating mode control commands to the energy storage component 12 in the power supply device 10.

[0082] In practical applications, communication handshakes can only be achieved between the power supply device 10 and the target device 30 after the interface component 14 in the power supply device 10 has completed a physical connection. Specifically, during the operation of the power supply device 10, the protocol chip 111 of the power supply device 10 can detect in real time whether the power supply device 10 and the target device 30 have completed a communication handshake. In this case, the protocol chip 111 can actively detect whether the power supply device 10 and the target device 30 have completed a communication handshake. In this embodiment, the protocol chip 111 is disposed within the body of the power supply device 10, and the protocol chip 111 can be implemented using functional chips, capacitors, and resistors.

[0083] In this embodiment, when the target device 30 connected to the power supply device 10 is an electrical load, the main control chip 112 can generate a discharge mode control command. After receiving the discharge mode control command sent by the main control chip 112, the energy storage component 12 can perform a discharge operation to release electrical energy to the electrical load, allowing the power supply device 10 to output electrical energy into the electrical load and supply power to it. When the target device 30 connected to the power supply device 10 is a power supply or an electrical load, the main control chip 112 can generate a charging mode control command. After receiving the charging mode control command sent by the main control chip 112, the energy storage component 12 can perform a charging operation to receive electrical energy from the power supply or the electrical load, allowing the power supply or the electrical load to output electrical energy into the power supply device 10 and charge it. It should be noted that the electrical energy released by the energy storage component 12 can be output through the power supply device 10, and the energy storage component 12 can also receive electrical energy from the power supply device through the power supply device 10.

[0084] In this embodiment, the power supply device can successfully control the working mode of the energy storage component by combining the protocol chip and the main control chip. At the same time, the main control chip will only control the working mode of the energy storage component when the protocol chip in the power supply device detects that the power supply device and the target device have successfully communicated and handed over. This can ensure that the energy storage component accurately receives or releases electrical energy and avoids wasting electrical energy.

[0085] In one embodiment, the above-mentioned operating mode can be a charging mode or a discharging mode.

[0086] Meanwhile, the energy storage component 12 in the power supply device 10 can be implemented by at least one of an energy storage battery pack, a power conversion unit, a control unit, and an energy storage current device. In this embodiment, the energy storage component 12 can be implemented by a power supply circuit and a capacitor. Optionally, the energy storage component 12 in the power supply device 10 is disposed inside the body of the power supply device 10 (i.e., the casing of the power supply device 10), and the energy storage component 12 can respond to the working mode control command sent by the processing chip 11 to switch the current working mode to the operating mode carried in the working mode control command.

[0087] In practical applications, the power supply device 10 can be connected to the target device 30 via a connecting cable to either supply electrical energy to the target device 30 or receive electrical energy supplied by the target device 30. Optionally, the target device 30 can be an electrical load or a power supply.

[0088] Optionally, the connection cable between the power supply device 10 and the target device 30 can be a type-c to Lightning cable, a type-c to type-c cable, or a type-c to USB cable.

[0089] Specifically, when the energy storage component 12 is in charging mode, it can receive electrical energy from the power supply connected to the power device 10 to store the energy; when the energy storage component 12 is in discharging mode, it can release electrical energy to the electrical load connected to the power device 10. Optionally, the power supply can be an AC mains power supply system, a switching power supply, an inverter power supply, a fixed power supply, etc.; the electrical load can be electronic devices such as mobile phones, computers, tablets, Bluetooth headsets, smart bracelets, and watches.

[0090] Furthermore, the safety management component 13 in the aforementioned power supply device 10 can be implemented through at least one of sensors, monitors, processing units, switches, etc. Specifically, the safety management component 13 can monitor the power supply device 10 in real time to see if any abnormality occurs when the energy storage component 12 is in operating mode. If an abnormality is detected in the power supply device 10, it sends an operating mode status control signal to the processing chip 11.

[0091] It should be noted that the safety management component 13 can monitor the operating data of the target component connected to it, and monitor whether the power supply device 10 malfunctions when the energy storage component 12 is in operating mode based on the operating data. Optionally, the aforementioned target component can be the processing chip 11 and / or the energy storage component 12.

[0092] In addition, the safety management component 13 can monitor the rate of change of the operating current of the target component and determine whether the power supply device 10 has malfunctioned when the energy storage component 12 is in operation mode based on the rate of change of the operating current of the target component. Specifically, if the rate of change of the operating current of the target component is less than or equal to a preset rate of change threshold, it is determined that the power supply device 10 has malfunctioned when the energy storage component 12 is in operation mode; otherwise, it is determined that the power supply device 10 has not malfunctioned when the energy storage component 12 is in operation mode. Optionally, the preset rate of change threshold can be custom-defined or determined based on historical experience values, and this embodiment of the application does not limit this.

[0093] Optionally, the aforementioned status control signal can be represented by a high-level signal or a low-level signal, or by other specific signals, to instruct the processing chip 11 to control the energy storage component 12 to stop operating mode, so as to ensure that when an abnormality occurs in the power supply device 10 during operation, the working state of the power supply device 10 can be interrupted in time, thereby improving the safety of the power supply device 10 during operation.

[0094] The technical solution in this application embodiment includes a power supply device comprising a processing chip, an energy storage component, and a safety management component. The processing chip includes a protocol chip and a main control chip. The protocol chip is connected to both the interface component and the main control chip. The main control chip is connected to both the energy storage component and the safety management component, and the energy storage component is connected to the safety management component. The safety management component monitors the power supply device when the energy storage component is in operating mode and sends a status control signal for the operating mode to the processing chip when the power supply device malfunctions. The main control chip detects whether the power supply device and the target device have completed a physical connection. The protocol chip detects whether the power supply device and the target device have completed a communication handshake when a physical connection is confirmed. The main control chip also controls the operating mode of the energy storage component and controls the energy storage component to stop operating mode based on the status control signal sent by the safety management component when a successful communication handshake is confirmed. When the safety management component in the aforementioned power supply equipment detects an abnormality during operation, it can promptly interrupt the operation of the power supply equipment, thereby improving its safety during operation and resolving potential safety hazards. Furthermore, the high level of safety during operation enhances the applicability of the power supply equipment, extends its lifespan, and reduces maintenance costs.

[0095] In some scenarios, the power supply device 10 can perform both charging and discharging operations without changing the connection cable. The structure of the power supply device 10 in this scenario is described below. In one embodiment, referring to Figure 1, the power supply device 10 further includes an interface component 14, which is connected to the protocol chip 111, the energy storage component 12, and the safety management component 13, respectively.

[0096] Interface component 14 is used to receive electrical energy sent by target device 30 connected to power supply device 10, or to release electrical energy to target device 30 connected to power supply device 10; target device 30 is a power supply or an electrical load.

[0097] In practical applications, in addition to the above-described structure, the power supply device 10 may also include an interface component 14, which is disposed on the body of the power supply device 10. One end of the interface component 14 is exposed on the surface of the body and is used to connect to the interface component 14 at one end of the connecting cable.

[0098] Specifically, when the power supply device 10 is in charging or discharging operation, the interface component 14 is used to receive electrical energy from the power supply connected to the power supply device 10 via a connection cable, or to release electrical energy to the electrical load connected to the power supply device 10 via a connection cable. In this embodiment, the interface component 14 has the function of bidirectional power transmission. Optionally, the interface component 14 can be a Lightning interface component 14, a Type-C interface component 14, or a USB interface component 14, etc.

[0099] In this embodiment, the interface component 14 of the power supply device 10 corresponds to the interface component 14 at one end of the connecting cable. If the interface component 14 in the power supply device 10 is a female interface component 14, the interface component 14 at one end of the connecting cable corresponding to the interface component 14 of the power supply device 10 can be a male interface component 14. Optionally, the interface component 14 can be implemented using an interface circuit and a capacitor. The interface circuit can be implemented using at least one of the following components: capacitor, inductor, and resistor.

[0100] The technical solution in this application embodiment further includes an interface component. The interface component is connected to the processing chip and the energy storage component respectively. The interface component is used to receive electrical energy sent by the target device connected to the power supply, or to release electrical energy to the target device connected to the power supply. The target device is a power supply or an electrical load. The power supply can release electrical energy to the electrical load or receive electrical energy from the power supply through the interface component, thereby enabling the power supply to have bidirectional charging and discharging functions. In actual use, the power supply does not need to repeatedly replace the connection cable or switch the connection interface between the power supply and the connection cable to perform charging or discharging operations, simplifying the charging and discharging operation of the power supply. At the same time, during operation, the power supply can reduce the number of times the connection cable is plugged and unplugged from the connection interface, avoiding the situation where the connection interface of the power supply becomes loose, causing damage to the connection interface and rendering the power supply unusable, thereby extending the service life of the power supply.

[0101] To improve the applicability of the power supply device 10, enabling it to perform charging or discharging operations not only when connected to a target device 30 with a Type-C charging interface, but also when connected to a target device 30 with an L charging interface, the power supply device 10 can be equipped with two different types of interface units. The two types of interface units on the power supply device 10 are described below. In one embodiment, as shown in FIG2, the interface component 14 in the power supply device 10 includes: a first interface unit 141 and / or a second interface unit 142. Both the first interface unit 141 and the second interface unit 142 are connected to the protocol chip 111; the first interface unit 141 and the second interface unit 142 have different interface types.

[0102] In practical applications, the interface component 14 may include a first interface unit 141 and / or a second interface unit 142. One end of the first interface unit 141 may be exposed on the surface of the power supply device 10 body for connection to the interface component 14 at one end of the connecting cable. Simultaneously, one end of the second interface unit 142 may also be exposed on the surface of the power supply device 10 body for connection to the interface component 14 at one end of the connecting cable. Both the first interface unit 141 and the second interface unit 142 in the interface component 14 are connected to the safety management component 13, but are not shown in Figure 2.

[0103] It should be noted that the first interface unit 141 and the second interface unit 142 are located in different positions and of different types. Optionally, both the first interface unit 141 and the second interface unit 142 can be implemented using a functional chip and a capacitor. In this embodiment, either the first interface unit 141 or the second interface unit 142 can be a Lightning interface unit, and the other interface unit can be a Type-C interface unit.

[0104] Specifically, when the power supply device 10 performs a discharge operation, the first interface unit 141 or the second interface unit 142 is specifically used to release electrical energy to the target device 30 connected to the power supply device 10 via a connection line; when the power supply device 10 performs a charging operation, the first interface unit 141 or the second interface unit 142 is specifically used to receive electrical energy sent by the target device 30 connected to the power supply device 10 via a connection line.

[0105] Meanwhile, the first interface unit 141 or the second interface unit 142 in the power supply device 10 corresponds to the interface component 14 at one end of the connecting cable. In this embodiment, the first interface unit 141 or the second interface unit 142 in the power supply device 10 is a Type-C female interface component, and the interface component at one end of the connecting cable corresponding to the first interface unit 141 or the second interface unit 142 of the power supply device 10 can be a Type-C male interface component; the second interface unit 142 or the first interface unit 141 in the power supply device 10 is an L female interface component, and the interface component 14 at one end of the connecting cable corresponding to the second interface unit 142 or the first interface unit 141 of the power supply device 10 can be an L male interface component.

[0106] For example, if the target device 30 is an electrical load and its interface is a Type-C interface, the Lightning interface of the connecting cable can be connected to the Lightning interface unit (first interface unit 141 or second interface unit 142) in the power supply device 10, and the Type-C interface of the connecting cable can be connected to the target device 30. The power supply device 10 then performs the operation of releasing electrical energy to the target device 30. If the target device 30 is a power supply and its interface is a Type-C interface, the Lightning interface of the connecting cable can be connected to the Lightning interface unit in the power supply device 10, and the Type-C interface of the connecting cable can be connected to the power supply. The power supply device 10 then performs the operation of receiving electrical energy sent by the power supply. It should be noted that both the first interface unit 141 and the second interface unit 142 have bidirectional charging and discharging functions.

[0107] In the technical solution of this application embodiment, the interface component in the power supply device includes a first interface unit and / or a second interface unit. Both the first interface unit and the second interface unit are connected to a protocol chip, and the interface types of the first interface unit and the second interface unit are different. The power supply device can release electrical energy to the electrical load or receive electrical energy from the power supply through the first interface unit and / or the second interface unit, thereby enabling the power supply device to have bidirectional charging and discharging functions. In actual use, the power supply device does not need to repeatedly change the connection cable or switch the connection interface between the power supply device and the connection cable to achieve charging or discharging operations, simplifying the charging and discharging operation of the power supply device. At the same time, this power supply... During operation, the device reduces the number of times the connection cable and power supply interface are plugged and unplugged, preventing loose connections that could damage the power supply interface and render it unusable, thus extending its lifespan. Furthermore, the power supply can be equipped with two different types of interface units, allowing it to connect to devices with Type-C charging interfaces for charging and discharging operations, as well as devices with L charging interfaces for releasing power. This makes the power supply compatible with various types of devices, expanding its application scenarios.

[0108] In some scenarios, there may be a mismatch in the communication signals between the power supply device 10 and the target device 30, leading to a failure of the communication handshake between the power supply device 10 and the target device 30. Based on this, in one embodiment, as shown in FIG3, the power supply device 10 further includes: a switch switching circuit 15, which is connected to the main control chip 112;

[0109] The main control chip 112 is also used to send a signal switching command to the switch switching circuit 15 when it is determined that the power supply device 10 and the target device 30 have failed to communicate and handshake. The switch switching circuit 15 is instructed to pull up the communication signal of the power supply device 10 so that the power supply device 10 and the target device 30 can successfully communicate and handshake.

[0110] Specifically, after determining that the communication handshake between the power supply device 10 and the target device 30 has failed, the protocol chip 111 in the power supply device 10 can generate a communication handshake failure message and send the communication handshake failure message to the main control chip 112. After receiving the communication handshake failure message, the main control chip 112 can generate a signal switching command and send the signal switching command to the switch switching circuit 15, instructing the switch switching circuit 15 to respond to the signal switching command and pull up the communication signal of the power supply device 10 so that the power supply device 10 and the target device 30 can successfully communicate and handshake.

[0111] It should be noted that when the communication handshake between the power supply device 10 and the target device 30 fails, the communication signal of the power supply device 10 is in a low-level state. In this embodiment, in order for the power supply device 10 and the target device 30 to successfully communicate, the communication signals of both the power supply device 10 and the target device 30 need to be in a high-level state. Therefore, when the communication handshake between the power supply device 10 and the target device 30 fails, the communication signal of the power supply device 10 can be pulled high. In this embodiment, the above-mentioned switch switching circuit 15 can be implemented using a functional chip, resistors, and capacitors.

[0112] Figure 4 shows the internal structure circuit diagram of the power supply device 10, excluding the main body, including the first interface unit 141, the second interface unit 142, the energy storage component 12, the protocol chip 111, the main control chip 112, and the switch switching circuit 15. Specifically, Figure 4 is the circuit structure diagram between the interface component 14 (including the first interface unit 141 and the second interface unit 142), the protocol chip 111, the main control chip 112, the energy storage component 12, and the switch switching circuit. In Figure 4, the lines leading out from the same pins in each part are connected together. For example, the CC1 pins in the first interface unit 141, the switch switching circuit, and the second interface unit 142 are all connected together. The single-function pins on each part in Figure 4 are connected to pins on other devices outside the power supply device 10, such as pins FB and FB on the main control chip 112 and pin VBUS0 on the second interface unit 142. It should be noted that a single-function pin refers to a specific pin on one of the circuits in the power supply device 10 that does not exist on other circuits in the power supply device 10.

[0113] In this embodiment of the application, after determining that the power supply device and the target device have failed to communicate and handshake, the power supply device can raise its own communication signal to enable the power supply device and the target device to successfully communicate and handshake, thereby ensuring that the power supply device can operate normally to perform charging and discharging operations, so as to release electrical energy to the electrical load or receive electrical energy sent by the power supply.

[0114] The following embodiments of this application will describe how the power supply device 10 enters the charging mode or discharging mode. In one embodiment, the main control chip 112 in the power supply device 10 is also used to detect the type of the target device 30. If the type of the target device 30 is determined to be a power supply, the operating mode of the energy storage component 12 is controlled to be the charging mode. If the type of the target device 30 is determined to be an electrical load, the operating mode of the energy storage component 12 is controlled to be the discharging mode.

[0115] Specifically, the main control chip 112 in the power supply device 10 can determine the type of the target device 30 connected to the first interface unit 141 or the second interface unit 142 by detecting the interface components of the target device 30 connected to the first interface unit 141 or the second interface unit 142. If the target device 30 is determined to be a power supply, a charging mode control command can be generated and sent to the energy storage component 12 to control the operation mode of the energy storage component 12 to be in charging mode; if the target device 30 is determined to be an electrical load, a discharging mode control command can be generated and sent to the energy storage component 12 to control the operation mode of the energy storage component 12 to be in discharging mode.

[0116] In this embodiment, the main control chip in the power supply device can detect the type of the target device connected to it, and then control the energy storage component to enter the charging mode or the discharging mode according to the type of the target device. This allows the power supply device to correctly enter different working modes, avoiding the problem of working mode disorder and preventing damage to the power supply device due to working mode disorder, thereby extending the service life of the power supply device.

[0117] In one embodiment, the safety management component 13 in the power supply device 10 is connected to the target component, which includes at least one of the interface component 14 and the energy storage component 12.

[0118] The safety management component 13 is also used to monitor the operating data of the target component and determine whether the power supply device 10 has an abnormality when the energy storage component 12 is in the operating mode. If so, it sends the operating mode status control signal to the processing chip 11.

[0119] The target component can be the processing chip 11, interface component 14, and / or energy storage component 12 in the power supply device 10. Optionally, the operating data of the target component can be the operating time of the processing chip 11, interface component 14, and / or energy storage component 12, the operating status of the processing chip 11, interface component 14, and / or energy storage component 12, or other operating parameters of the processing chip 11, interface component 14, and / or energy storage component 12.

[0120] In one implementation, the safety management component 13 can input operating data into a pre-trained algorithm model, which determines whether the power supply device 10 has an anomaly when the energy storage component 12 is in operating mode based on the operating data.

[0121] In another implementation, the safety management component 13 can compare and process the operating data to determine whether the power supply device 10 has malfunctioned when the energy storage component 12 is in operating mode.

[0122] In this embodiment of the application, if it is determined that the power device 10 has malfunctioned while the energy storage component 12 is in the operating mode, the safety management component 13 can send a status control signal of the operating mode to the processing chip 11, instructing the processing chip 11 to control the energy storage component 12 to stop operating in the operating mode.

[0123] In one embodiment, if the target component includes interface component 14, the operating data includes the operating temperature of interface component 14; and the safety management component 13 is used to monitor the operating temperature of interface component 14, and if the operating temperature is greater than or equal to a preset temperature threshold, then it is determined that the power device 10 has malfunctioned when the energy storage component 12 is in the operating mode.

[0124] In this embodiment, if the safety management component 13 in the power supply device 10 is only connected to the interface component 14, the safety management component 13 can monitor the operating temperature of the interface component 14 and determine whether the operating temperature is greater than or equal to a preset temperature threshold. If the operating temperature is greater than or equal to the preset temperature threshold, it is determined that the power supply device 10 has an abnormality when the energy storage component 12 is in the operating mode; otherwise, it is determined that the power supply device 10 has not an abnormality when the energy storage component 12 is in the operating mode.

[0125] Optionally, the aforementioned preset temperature threshold can be user-defined or determined based on historical experience values; this embodiment of the application does not limit this.

[0126] In one embodiment, if the target component includes an energy storage component 12, the operating data includes the operating current of the energy storage component 12; the safety management component 13 is used to monitor the operating current of the energy storage component 12, and if the operating current is greater than or equal to a preset current threshold, it is determined that the power supply device 10 has malfunctioned when the energy storage component 12 is in the operating mode.

[0127] In this embodiment, if the safety management component 13 in the power supply device 10 is only connected to the energy storage component 12, the safety management component 13 can monitor the operating current of the energy storage component 12 and determine whether the operating current is greater than or equal to a preset current threshold. If the operating current is greater than or equal to the preset current threshold, it is determined that the power supply device 10 has an abnormality when the energy storage component 12 is in the operating mode; otherwise, it is determined that the power supply device 10 has not an abnormality when the energy storage component 12 is in the operating mode.

[0128] Optionally, the aforementioned preset current threshold can be user-defined or determined based on historical experience values; this application embodiment does not limit this.

[0129] In addition, the safety management component 13 in the power supply device 10 can be connected to both the interface component 14 and the energy storage component 12. In this case, the safety management component 13 can simultaneously monitor the operating temperature of the interface component 14 and the operating current of the energy storage component 12. If the operating current is greater than or equal to a preset current threshold and / or the operating temperature is greater than or equal to a preset temperature threshold, the safety management component 13 can determine that an abnormality has occurred in the power supply device 10 when the energy storage component 12 is in the operating mode.

[0130] In the technical solution of this application embodiment, the safety management component in the power supply device is connected to the target component. The target component includes at least one of an interface component and an energy storage component. The safety management component is also used to monitor the operating data of the target component and determine whether the power supply device has an abnormality when the energy storage component is in the operating mode based on the operating data. If so, it sends a status control signal of the operating mode to the processing chip. The safety management component in the power supply device can monitor whether the power supply device has an abnormality in real time during the operation of the power supply device. It can notify the processing chip in a timely manner to control the start and stop status of the energy storage component in the charging mode or discharging mode based on the monitoring results, thereby improving the safety of the power supply device during operation and solving the safety hazards that exist in the operation of the power supply device.

[0131] In addition, this application embodiment also provides a power system, as shown in FIG5. The power system includes a connecting line 20 and a power device 10 in any of the above embodiments; the power device 10 is connected to the target device 30 through the connecting line 20.

[0132] In practical applications, the aforementioned connecting cable 20 can be a pluggable connecting cable, and can be a data cable, fast charging cable, or vehicle charging cable, etc. Specifically, the interface type at one end of the connecting cable 20 corresponds to the interface type of the first interface unit 141 or the second interface unit 142 in the power supply device 10, and the interface type at the other end of the connecting cable 20 corresponds to the interface type of the target device 30. Optionally, the target device 30 can be an electrical load or a power supply.

[0133] In one embodiment, as shown in FIG6, the connection line 20 in the power supply system includes: a first interface component 21, a second interface component 22 and a control switch circuit 23. The first interface component 21 is connected to one end of the control switch circuit 23, and the other end of the control switch circuit 23 is connected to the second interface component 22.

[0134] The control switch circuit 23 is used to control the flow of electrical energy from the first interface component 21 to the second interface component 22, or control the flow of electrical energy from the second interface component 22 to the first interface component 21, when it is determined that the power supply device 10 and the target device 30 have completed a communication handshake.

[0135] In this embodiment, the connecting line 20 in the power system has both data transmission and power transmission functions; that is, the connecting line 20 can be used as both a data line and a power line. During operation, the first interface component 21 of the connecting line 20 is connected to the first interface unit 141 or the second interface unit 142 of the power device 10, and the second interface component 22 of the connecting line 20 is connected to the second interface unit 142 or the first interface unit 141 of the power device 10.

[0136] In practical applications, after connecting the target device 30 to the power supply device 10 through the connection cable 20, the power supply device 10 can perform fast charging on the target device 30 (i.e., the power supply device 10 performs a charging operation), or the power supply device can perform fast charging on the power supply device 10 (i.e., the power supply device 10 performs a discharging operation).

[0137] In this embodiment, the first interface unit 141 or the second interface unit 142 of the power supply device 10 is an L-type female interface component, and correspondingly, the first interface component 21 of the connecting line 20 is an L-type male interface component; the second interface unit 142 or the first interface unit 141 of the power supply device 10 is a Type-C female interface component, and correspondingly, the second interface component 22 of the connecting line 20 is a Type-C male interface component. In this embodiment, both the first interface component 21 and the second interface component 22 of the connecting line 20 can be implemented through interface circuits.

[0138] The control switch circuit 23 in the aforementioned connection line 20 can control the flow of electrical energy from the first interface component 21 to the second interface component 22 of the connection line 20 in real time, or control the flow of electrical energy from the second interface component 22 to the first interface component 21 of the connection line 20. In practical applications, to save the electrical energy consumed by the connection line 20, the control function executed by the control switch circuit 23 in the connection line 20 only takes effect after the power supply device 10 and the target device 30 have successfully communicated and shaken hands. In this embodiment, the control switch circuit 23 of the connection line 20 can be implemented using resistors and MOSFETs.

[0139] In one embodiment, as shown in FIG7, the connection line 20 further includes: a control communication circuit 24; the control communication circuit 24 is connected to the first interface component 21 and the control switch circuit 23 respectively;

[0140] The control communication circuit 24 is used to control the communication handshake between the power supply device 10 and the target device 30 when the power supply device 10 and the target device 30 are connected by the connection line 20.

[0141] In this embodiment, one end of the control communication circuit 24 is connected to the first interface component 21 and the control switch circuit 23, respectively, and the other end of the control communication circuit 24 is grounded. Optionally, after determining that the power supply device 10 and the target device 30 have successfully completed a communication handshake, the control communication circuit 24 can generate a communication handshake success message and send the communication handshake success message to the control switch circuit 23 in the connection line 20. After receiving the communication handshake success message, the control switch circuit 23 triggers its own control function to control the flow of electrical energy from the first interface component 21 to the second interface component 22 of the connection line 20, or to control the flow of electrical energy from the second interface component 22 to the first interface component 21 of the connection line 20.

[0142] Please refer to Figure 8, which shows the internal circuit structure of the connection line 20 in the power supply system. The lines leading out from the same pins on each part of the connection line 20 in Figure 8 are all connected together. The single-function pins on each part are connected to the pins on other devices outside the connection line 20, such as the pin MOS_G on the control switch circuit 23.

[0143] In this embodiment, after the power supply device 10 and the target device 30 are connected via the connection line 20, the control communication circuit 24 in the connection line 20 can control the power supply device 10 and the target device 30 to perform a communication handshake. This control communication circuit 24 can also be understood as a circuit that controls communication between the first interface component 21 and the second interface component 22 of the connection line 20. In this embodiment, the control communication circuit 24 of the connection line 20 can be implemented using a functional chip, resistors, capacitors, and a transient voltage suppressor diode (TVS).

[0144] In practical applications, the power supply device 10 in the power supply system can release electrical energy to or receive electrical energy from different types of target devices 30 simply by using the connection line 20 in the power supply system. That is, the connection line 20 in the power supply system is a multi-functional connection line 20 with the function of bidirectional transmission of electrical energy or data.

[0145] In this embodiment, the connecting line 20 is equipped with two control circuits (control switch circuit 23 and control communication circuit 24), which enables the connecting line 20 to have a dual communication security guarantee function. It can not only control the power supply device 10 in the power system to communicate and handshake with the target device 30, but also control the power transmission between the power supply device 10 and the target device 30, thereby enabling the power supply device 10 and the target device 30 to be safely connected and operated.

[0146] The power system in this embodiment includes a power supply device and connecting cables. In practical applications, the power supply device can be connected to different types of target devices simply through the connecting cables, enabling it to supply power to different types of target devices or charge itself, thereby expanding the application scenarios for the power supply device and connecting cables. Simultaneously, the power supply device used in the power system can promptly interrupt its operation when an abnormality is detected during operation, improving the safety of the power supply device during operation and resolving potential safety hazards. Furthermore, the high safety of the power supply device during operation enhances the applicability of the power system, extends the lifespan of the power supply device, and reduces maintenance costs.

[0147] This application provides a control method applied to a safety management component within a power supply device in any of the above embodiments, as shown in FIG9. The method may include the following steps:

[0148] S100. Monitor the power supply equipment when the energy storage components in the power supply equipment are in operating mode.

[0149] In practical applications, the safety management component monitors the power supply equipment for abnormalities when the energy storage component is in operating mode. Specifically, if an abnormality occurs, the safety management component within the power supply equipment can output an alarm signal. Correspondingly, if the safety management component outputs an alarm signal, it can be determined that an abnormality occurred in the power supply equipment while the energy storage component is in operating mode; if the safety management component does not output an alarm signal, it can be determined that no abnormality occurred in the power supply equipment while the energy storage component is in operating mode.

[0150] In one embodiment, the energy storage component in the power supply device is put into operating mode by the main control chip in the power supply device after determining that the power supply device and the target device have completed a communication handshake.

[0151] It should be noted that the main control chip in the power supply device can detect whether the power supply device and the target device have completed a physical connection. Specifically, the main control chip can detect whether the corresponding pins on the interface unit (first interface unit or second interface unit) where the power supply device and the target device interface are in contact to determine whether a physical connection has been established.

[0152] If contact is detected between the corresponding pins on the interface unit where the power supply device and the target device are connected, it is determined that the power supply device and the target device have completed a physical connection. If no contact or incomplete contact is detected between the corresponding pins on the interface unit where the power supply device and the target device are connected, it is determined that the power supply device and the target device have not completed a physical connection.

[0153] Meanwhile, after determining that the power supply device and the target device have completed the physical connection, the main control chip in the power supply device can generate a communication handshake detection command and send the communication handshake detection command to the protocol chip in the power supply device, so that the protocol chip can respond to the communication handshake detection command and start detecting whether the power supply device and the target device have completed the communication handshake.

[0154] In this embodiment, power or data transmission can only occur between the power supply device and the target device after a successful communication handshake. Specifically, power transmission is primarily implemented between the power supply device and the target device. After the power supply device and the target device are connected via a connecting cable, the control communication circuit in the connecting cable can control the power supply device and the target device to perform a communication handshake. It should be noted that in practical applications, the power supply device needs to be connected to the target device (electrical load or power supply) via a connecting cable. Correspondingly, the power supply device and the target device do not directly perform a communication handshake; instead, the control communication circuit in the connecting cable controls the communication handshake between the power supply device and the target device.

[0155] Meanwhile, after confirming that the power supply device and the target device have completed the communication handshake, the control communication circuit in the connection line can send a communication handshake success message to the control switch circuit in the connection line. Upon receiving the communication handshake success message, the control switch circuit triggers its own control function to control the flow of electrical energy from the first interface component of the connection line to the second interface component of the connection line, or to control the flow of electrical energy from the second interface component of the connection line to the first interface component of the connection line.

[0156] In addition, after determining that the power supply device and the target device have completed the communication handshake, the protocol chip in the power supply device can generate a handshake success command and send the handshake success command to the main control chip to inform the main control chip that the power supply device and the target device have successfully completed the handshake.

[0157] Furthermore, after receiving the handshake success command, the main control chip in the power supply device can generate a working mode control command, and then send the working mode control command to the energy storage component in the power supply device to control the energy storage component to adjust the working mode to charging mode or discharging mode.

[0158] The operating mode control command refers to the command that controls the operating mode of the energy storage component in the power supply device. This operating mode control command can be a charging mode control command or a discharging mode control command. It should be noted that when the energy storage component receives the charging mode control command sent by the main control chip, the energy storage component enters the charging mode to receive the electrical energy output from the power supply connected to the power supply device. When the energy storage component receives the discharging mode control command sent by the main control chip, the energy storage component enters the discharging mode to release electrical energy to supply power to the electrical load connected to the power supply device.

[0159] S200. If the power supply device malfunctions, a status control signal for the operating mode is sent to the processing chip in the power supply device. The status control signal is used to instruct the processing chip to control the energy storage component to stop operating.

[0160] Specifically, when the safety management component detects an abnormality in the power supply equipment while the energy storage component is in operation mode, it can directly send a status control signal to the processing chip in the power supply equipment to control the operation mode, instructing the processing chip to control the energy storage component to stop operating.

[0161] Optionally, the aforementioned state control signal can be represented by a high-level signal or a low-level signal, and this embodiment of the application does not limit this.

[0162] The technical solution in this application embodiment is applied to a safety management component in a power supply device. When the energy storage component in the power supply device is in operating mode, the device is monitored. If an abnormality occurs, a status control signal for the operating mode is sent to the processing chip in the power supply device, instructing the processing chip to control the energy storage component to stop operating. This method can promptly interrupt the operation of the power supply device when an abnormality is detected during operation, improving the safety of the power supply device during operation and resolving potential safety hazards. Furthermore, this method ensures high safety during operation, thereby improving the applicability of the power supply device, extending its service life, and reducing maintenance costs.

[0163] The process of monitoring the power supply device when the energy storage component is in operation mode is described below. In one embodiment, as shown in FIG10, the steps in S100 above may include:

[0164] S110. Obtain the operating data of the target component in the power supply device; the target component includes at least one of the interface component and the energy storage component in the power supply device.

[0165] The safety management component can monitor the operational data of the target components connected to it. Optionally, the operational data of the target components can be the operating duration of the interface components and / or energy storage components, the operating status of the interface components and / or energy storage components, or other operating parameters of the interface components and / or energy storage components.

[0166] S120. Monitor whether any abnormalities occur in the power supply equipment when the energy storage component is in operation mode based on the operation data.

[0167] Specifically, the safety management component can pre-train an algorithm model and then input the operating data into the pre-trained algorithm model. The algorithm model monitors whether the power equipment experiences any abnormalities when the energy storage component is in operation mode based on the operating data.

[0168] In addition, the safety management component can compare and process the operating data to determine whether the power equipment has malfunctioned when the energy storage component is in operation mode.

[0169] In one embodiment, the above-mentioned operating data includes the operating temperature of the interface component; the step of monitoring whether the power device is abnormal when the energy storage component is in the operating mode based on the operating data in S120 may include: if the operating temperature is greater than or equal to a preset temperature threshold, then it is determined that the power device is abnormal when the energy storage component is in the operating mode.

[0170] In this embodiment of the application, if the safety management component in the power supply device is only connected to the interface component, the safety management component can monitor the operating temperature of the interface component and determine whether the operating temperature is greater than or equal to a preset temperature threshold. If the operating temperature is greater than or equal to the preset temperature threshold, it is determined that the power supply device has an abnormality when the energy storage component is in the operating mode; otherwise, it is determined that the power supply device has not an abnormality when the energy storage component is in the operating mode.

[0171] Optionally, the aforementioned preset temperature threshold can be user-defined or determined based on historical experience values; this embodiment of the application does not limit this.

[0172] In one embodiment, the aforementioned operating data includes the operating current of the energy storage component; the step in S120 of monitoring whether an abnormality occurs in the power supply device when the energy storage component is in operating mode based on the operating data may include:

[0173] If the operating current is greater than or equal to the preset current threshold, it is determined that the power supply device has malfunctioned while the energy storage component is in operation mode.

[0174] In this embodiment of the application, if the safety management component in the power supply device is only connected to the energy storage component, the safety management component can monitor the operating current of the energy storage component and determine whether the operating current is greater than or equal to a preset current threshold. If the operating current is greater than or equal to the preset current threshold, it is determined that the power supply device has an abnormality when the energy storage component is in the operating mode; otherwise, it is determined that the power supply device has not an abnormality when the energy storage component is in the operating mode.

[0175] Optionally, the aforementioned preset current threshold can be user-defined or determined based on historical experience values; this application embodiment does not limit this.

[0176] In addition, the safety management component in the power supply equipment can be connected to both the interface component and the energy storage component at the same time. In this case, the safety management component can simultaneously monitor the operating temperature of the interface component and the operating current of the energy storage component, and determine that the power supply equipment has malfunctioned when the energy storage component is in operation mode if the operating current is greater than or equal to a preset current threshold and / or the operating temperature is greater than or equal to a preset temperature threshold.

[0177] The technical solution in this application embodiment obtains the operating data of the target component in the power supply device, and monitors whether the power supply device experiences any abnormalities when the energy storage component is in operating mode based on the operating data. This method does not require complex algorithms and the processing is relatively simple, thereby reducing the complexity of monitoring whether the power supply device experiences any abnormalities and improving the efficiency of monitoring whether the power supply device experiences any abnormalities.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
