[0065] In the field of charging and discharging, the power supply device is connected with the power supply or the power load through the connecting line to provide power for the power load or provide power for the power supply. Taking the most commonly used power supply device, the mobile power bank, as an example, when the mobile power bank supplies power to different types of power loads, the mobile power bank needs to be connected with the power load through the special connecting line corresponding to the power load to provide power for the power load. At the same time, when the power supply charges the mobile power bank, the mobile power bank also needs to be connected with the power supply through the special connecting line to provide power for the mobile power bank. However, the power supply device in the related art has certain safety hazards in the working process.

[0066] Therefore, the power supply device 10 provided by the embodiments of the present application can solve the safety hazards in the working process. As shown in FIG. 1, the structure block diagram of the power supply device 10, the power supply device 10 comprises a processing chip 11, an energy storage component 12 and a safety management component 13, the processing chip 11 comprises a protocol chip 111 and a master control chip 112, the protocol chip 111 is connected with the master control chip 112, the master control chip 112 is connected with the energy storage component 12 and the safety management component 13 respectively, and the energy storage component 12 is connected with the safety management component 13;

[0067] The safety management component 13 is configured to monitor the power supply device 10 when the energy storage component 12 is in the running mode, and send a state control signal of the running mode to the processing chip 11 when the power supply device 10 is abnormal.

[0068] The master control chip 112 is configured to detect whether the power supply device 10 and the target device 30 are physically connected.

[0069] The protocol chip 111 is configured to detect whether the power supply device 10 and the target device 30 complete the communication handshake under the condition that the power supply device 10 and the target device 30 complete the physical connection.

[0070] The master control chip 112 is further configured to control the running mode of the energy storage component 12 under the condition that the power supply device 10 and the target device 30 successfully complete the communication handshake, and control the energy storage component 12 to stop the running mode according to the state control signal sent by the safety management component 13.

[0071] The processing chip 11 in the power supply device 10 can be arranged in the body of the power supply device 10. Alternatively, the body of the power supply device 10 has the function of fixing other components in the power supply device 10. The shell can be made of thermoplastic plastic material made of polycarbonate and polyacrylonitrile alloy, or made of polycarbonate material, or made of other materials with high strength, good toughness, high temperature resistance and other properties.

[0072] Specifically, the processing chip 11 can be implemented by a plurality of different functional circuits, or can be understood as being implemented by at least one of a transistor, a resistor, a capacitor, etc. In the embodiment of the present application, the processing chip 11 can control the working mode of the energy storage component 12 in the power supply device 10, i.e. the charging mode or the discharging mode.

[0073] In the embodiment of the present application, the power supply device 10 can be provided with a key, a button or a touch screen for receiving the relevant instructions input by the user. In actual application, the user can input the working mode control instruction of the energy storage component 12 through the key, the button or the touch screen, and correspondingly, the processing chip 11 can respond to the working mode control instruction to control the energy storage component 12 in the power supply device 10 to switch the current working mode to the running mode carried in the working mode control instruction.

[0074] In the embodiment of the present application, the processing chip 11 in the power supply device 10 can include a protocol chip 111 and a master control chip 112. Alternatively, the protocol chip 111 and the master control chip 112 can be implemented by at least one of a transistor, a capacitor and a resistor, etc.

[0075] In one embodiment, the protocol chip 111 in the processing chip 11 is further configured to send a handshake success instruction to the master control chip 112 to instruct the master control chip 112 to control the energy storage component 12 to be in the running mode, in the case that the power supply device 10 successfully communicates with the target device 30.

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

[0077] The master control chip 112 in the power supply device 10 can be arranged in the body of the power supply device 10, and can be implemented by a plurality of different functional circuits, such as an analog-to-digital conversion circuit or a digital-to-analog conversion circuit, etc. The analog-to-digital conversion circuit is configured to convert the analog signal received by the power supply device 10 into a digital signal, and the digital-to-analog conversion circuit is configured to convert the digital signal received by the power supply device 10 into an analog signal.

[0078] In the embodiment of the present application, the main control chip 112 can be a processing chip 11 with detection and control functions, which can detect whether the power supply device 10 and the target device 30 are physically connected. The physical connection can be understood as that the power supply device 10 of the power supply device 10 is connected to the target device 30 through a connecting line, that is, the interface at one end of the connecting line is connected to the power supply device 10, and the interface at the other end of the connecting line is connected to the interface of the target device 30. In the embodiment of the present application, the main control chip 112 can be implemented by a functional chip and a resistor.

[0079] In one embodiment, the main control chip 112 in the processing chip 11 is also used to send a communication handshake detection instruction to the protocol chip 111 to instruct the protocol chip 111 to detect whether the power supply device 10 and the target device 30 complete the communication handshake when it is determined that the interface assembly 14 in the power supply device 10 and the target device 30 complete the physical connection.

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

[0081] Specifically, during the working process of the power supply device 10, the main control chip 112 in the power supply device 10 can continuously generate a working mode control instruction, and the protocol chip 111 in the power supply device 10 can successfully send the working mode control instruction to the energy storage assembly 12 in the power supply device 10 only after it is determined that the power supply device 10 and the target device 30 complete the communication handshake.

[0082] In actual application, only when the interface assembly 14 in the power supply device 10 and the target device 30 complete the physical connection, the power supply device 10 and the target device 30 can further implement the communication handshake. Specifically, during the working process of the power supply device 10, the protocol chip 111 of the power supply device 10 can detect whether the power supply device 10 and the target device 30 complete the communication handshake in real time. In this case, the protocol chip 111 can actively implement the process of detecting whether the power supply device 10 and the target device 30 complete the communication handshake. In the embodiment of the present application, the protocol chip 111 is arranged in the body of the power supply device 10, and the protocol chip 111 can be implemented by a functional chip, a capacitor and a resistor.

[0083] In the embodiment of the present application, when the target device 30 connected with the power supply device 10 is a power load, the master control chip 112 can generate a discharge mode control instruction, and after the energy storage assembly 12 receives the discharge mode control instruction sent by the master control chip 112, the energy storage assembly 12 can perform a discharge operation to release electrical energy to the power load, so that the electrical energy output by the power supply device 10 enters the power load to supply power to the power load; when the target device 30 connected with the power supply device 10 is a power supply or a power load, the master control chip 112 can generate a charging mode control instruction, and after the energy storage assembly 12 receives the charging mode control instruction sent by the master control chip 112, the energy storage assembly 12 can perform a charging operation to receive the electrical energy sent by the power supply or the power load, so that the electrical energy output by the power supply or the power load enters the power supply device 10 to charge the power supply device 10. It should be noted that the electrical energy released by the energy storage assembly 12 can be output through the power supply device 10, and the energy storage assembly 12 can also receive the electrical energy of the power supply device through the power supply device 10.

[0084] The power supply device in the embodiment can successfully control the working mode of the energy storage assembly by combining the protocol chip and the master control chip; at the same time, the master control chip will control the working mode of the energy storage assembly only when the protocol chip in the power supply device detects that the power supply device and the target device successfully communicate and handshake, so as to ensure that the energy storage assembly accurately receives or releases electrical energy and avoid wasting electrical energy.

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

[0086] At the same time, the energy storage assembly 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 the embodiment of the present application, the energy storage assembly 12 can be implemented by a power supply circuit and a capacitor. Alternatively, the energy storage assembly 12 in the power supply device 10 is arranged in the body (i.e. the shell) of the power supply device 10, and the energy storage assembly 12 can switch the current working mode to the running mode carried in the working mode control instruction sent by the processing chip 11 in response to the working mode control instruction.

[0087] In actual application, the power supply device 10 can be connected with the target device 30 through a connection line to release electrical energy to the target device 30 or receive the electrical energy released by the target device 30. Alternatively, the above-mentioned target device 30 can be a power load or a power supply.

[0088] Alternatively, the connection line connecting the power supply device 10 and the target device 30 can be a cable converting a type-c interface to a Lightning interface, a cable converting a type-c interface to a type-c interface, or a cable converting a type-c interface to a USB interface.

[0089] Specifically, when the energy storage component 12 is in the charging mode, the energy storage component 12 can receive the electric energy transmitted by the power supply connected to the power supply device 10 to store the electric energy; when the energy storage component 12 is in the discharging mode, the energy storage component 12 can release the electric energy to the power consumption load connected to the power supply device 10. Alternatively, the power supply described above can be an AC power supply system, a switching power supply, an inverter power supply, a fixed power supply, etc.; the power consumption load described above can be a mobile phone, a computer, a tablet, a Bluetooth headset, a smart bracelet, a watch, etc. electronic equipment.

[0090] In addition, the safety management component 13 in the power supply device 10 described above can be implemented by at least one of a sensor, a monitor, a processing unit, a switch, etc. Among them, the safety management component 13 can monitor whether the power supply device 10 is abnormal in real time when the energy storage component 12 is in the running mode, and send a state control signal of the running mode to the processing chip 11 if it is monitored that the power supply device 10 is abnormal.

[0091] It should be noted here that the safety management component 13 can monitor the running data of the target component connected thereto, and monitor whether the power supply device 10 is abnormal when the energy storage component 12 is in the running mode according to the running data. Alternatively, the target component described above can be the processing chip 11 and / or the energy storage component 12.

[0092] In addition, the safety management component 13 can monitor the working current change rate of the target component, and determine whether the power supply device 10 is abnormal when the energy storage component 12 is in the running mode according to the working current change rate of the target component. Among them, if the working current change rate of the target component is less than or equal to a preset change rate threshold, it is determined that the power supply device 10 is abnormal when the energy storage component 12 is in the running mode, otherwise, it is determined that the power supply device 10 is not abnormal when the energy storage component 12 is in the running mode. Alternatively, the preset change rate threshold can be self-defined, and can also be determined according to historical experience value, which is not limited by the embodiments of the present application.

[0093] Alternatively, the state control signal described above can be represented by a high-level signal or a low-level signal, and can also be represented by other specific signals, which is used to instruct the processing chip 11 to control the energy storage component 12 to stop running in the running mode, so as to ensure that the power supply device 10 can be interrupted in time when the power supply device 10 is abnormal in the working process, and improve the safety of the power supply device 10 in the working process.

[0100] The technical solution in the embodiment of the application, the power supply device further comprises an interface assembly connected with the processing chip and the energy storage assembly respectively, the interface assembly is used to receive the electric energy transmitted by the target device connected with the power supply device or release the electric energy to the target device connected with the power supply device; the target device is a power supply source or a power consumption load; the power supply device can release the electric energy to the power consumption load or receive the electric energy of the power supply source through the interface assembly, so that the power supply device has the function of bidirectional charging and discharging, and when the power supply device is actually used, the connection interface of the connecting line and the power supply device does not need to be repeatedly replaced, the charging operation or the discharging operation of the power supply device can be realized by switching the connection interface of the power supply device and the connecting line, so that the charging and discharging operation of the power supply device is simplified; at the same time, the power supply device can reduce the plugging frequency of the connection interface of the connecting line and the power supply device in the working process, so that the power supply device can avoid the situation that the connection interface of the power supply device is loose and the connection interface of the power supply device is damaged so as to cause the power supply device to be unable to be normally used, thereby prolonging the service life of the power supply device.

[0101] In order to improve the applicable scenarios of the power supply device 10, not only the power supply device 10 can perform the charging operation or the discharging operation after being connected with the target device 30 having the type-c charging interface, but also the power supply device 10 can perform the charging operation or the discharging operation after being connected with the target device 30 having the L charging interface, and the power supply device 10 can be provided with two different types of interface units, and the two types of interface units provided on the power supply device 10 will be described below. In an embodiment, as shown in FIG. 2, the interface assembly 14 in the power supply device 10 includes a first interface unit 141 and / or a second interface unit 142, and the first interface unit 141 and the second interface unit 142 are connected with the protocol chip 111; the interface types of the first interface unit 141 and the second interface unit 142 are different.

[0102] In actual application, the interface assembly 14 can include the first interface unit 141 and / or the second interface unit 142. One end of the first interface unit 141 can be exposed on the surface of the body of the power supply device 10, and used to be connected with the interface assembly 14 at one end of the connecting line. Meanwhile, one end of the second interface unit 142 can also be exposed on the surface of the body of the power supply device 10, and used to be connected with the interface assembly 14 at one end of the connecting line. The first interface unit 141 and the second interface unit 142 in the interface assembly 14 are connected with the security management assembly 13, but not shown in FIG. 2.

[0103] It should be noted that the first interface unit 141 and the second interface unit 142 are different in setting position and type. Alternatively, the first interface unit 141 and the second interface unit 142 can be implemented by a functional chip and a capacitor. In the embodiment of the present application, any one of the first interface unit 141 and 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 the discharging operation, the first interface unit 141 or the second interface unit 142 is specifically used to release electric energy to the target device 30 connected with the power supply device 10 through the connecting line; when the power supply device 10 performs the charging operation, the first interface unit 141 or the second interface unit 142 is specifically used to receive the electric energy sent by the target device 30 connected with the power supply device 10 through the connecting line.

[0105] Meanwhile, the first interface unit 141 or the second interface unit 142 in the power supply device 10 corresponds to the interface assembly 14 at one end of the connection line. In the embodiment of the present application, the first interface unit 141 or the second interface unit 142 in the power supply device 10 is a type-c female socket interface assembly, and the interface assembly at one end of the connection line 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 plug interface assembly; the second interface unit 142 or the first interface unit 141 in the power supply device 10 is an L female socket interface assembly, and the interface assembly 14 at one end of the connection line corresponding to the second interface unit 142 or the first interface unit 141 of the power supply device 10 can be an L male plug interface assembly.

[0106] Exemplarily, if the target device 30 is a power consumption load and the interface of the power consumption load is a type-c interface, the Lightning interface of the connection line can be connected with the Lightning interface unit (the first interface unit 141 or the second interface unit 142) in the power supply device 10, and the type-c interface of the connection line is connected with the target device 30, and further the power supply device 10 performs the operation of releasing electric energy to the target device 30; if the target device 30 is a power supply and the interface of the power supply is a type-c interface, the Lightning interface of the connection line can be connected with the Lightning interface unit in the power supply device 10, and the type-c interface of the connection line is connected with the power supply, and further the power supply device 10 performs the operation of receiving electric energy sent by the power supply. It should be noted that the first interface unit 141 and the second interface unit 142 both have the function of bidirectional charging and discharging.

[0107] The technical solutions in the embodiments of the present application, the interface component in the power supply device includes a first interface unit and / or a second interface unit, the first interface unit and the second interface unit are connected with 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 electric energy to the power consumption load or receive electric energy of the power supply through the first interface unit and / or the second interface unit, so that the power supply device has a bidirectional charging and discharging function, and when the power supply device is actually used, the connection line does not need to be repeatedly replaced, the connection interface of the power supply device and the connection line is switched, so that the power supply device can realize charging operation or discharging operation, and the charging and discharging operation of the power supply device is simplified; meanwhile, the power supply device can reduce the plugging frequency of the connection line and the connection interface of the power supply device in the working process, can avoid the loosening of the connection interface of the power supply device, and cause the connection interface of the power supply device to be damaged so as to cause the power supply device to be unable to be normally used, so that the use cycle of the power supply device can be prolonged; in addition, two different types of interface units can be arranged in the power supply device, so that the power supply device can not only be connected with the target device having a type-c charging interface to perform charging and discharging operation, but also can be connected with the target device having an L charging interface to perform charging and discharging operation to release electric energy, that is, the power supply can be applied to connection with various types of target devices to realize charging and discharging operation, and the use scene of the power supply device is improved.

[0108] In some scenarios, there can be a problem of mismatching of communication signals between the power supply device 10 and the target device 30, causing the power supply device 10 and the target device 30 to fail in communication handshake. Based on this, in an embodiment, as shown in FIG. 3, the power supply device 10 further includes a switch switching circuit 15 connected with the master control chip 112;

[0109] The master control chip 112 is further configured to send a signal switching instruction to the switch switching circuit 15 to pull up the communication signal of the power supply device 10 to make the power supply device 10 and the target device 30 successfully communicate handshake in a case where it is determined that the power supply device 10 and the target device 30 fail in communication handshake.

[0110] Specifically, the protocol chip 111 in the power supply device 10 can generate a communication handshake failure message after determining that the power supply device 10 and the target device 30 fail in communication handshake, and send the communication handshake failure message to the master control chip 112, and the master control chip 112 can generate a signal switching instruction after receiving the communication handshake failure information, and send the signal switching instruction to the switch switching circuit 15 to pull up the communication signal of the power supply device 10 in response to the signal switching instruction to make the power supply device 10 and the target device 30 successfully communicate handshake.

[0111] It should be noted that when the power supply device 10 fails to handshake with the target device 30, the communication signal of the power supply device 10 is in a low level state. In the embodiment of the present application, in order to successfully handshake between the power supply device 10 and the target device 30, the communication signals of the power supply device 10 and the target device 30 need to meet the high level state. Therefore, when the power supply device 10 fails to handshake with the target device 30, the communication signal of the power supply device 10 can be pulled high. In the embodiment of the present application, the above-mentioned switch switching circuit 15 can be realized by a functional chip, a resistor and a capacitor.

[0112] In the embodiment of the present application, the internal structure circuit diagram of the first interface unit 141, the second interface unit 142, the energy storage assembly 12, the protocol chip 111, the master control chip 112 and the switch switching circuit 15 in the power supply device 10 is shown in FIG. 4, that is, FIG. 4 is a circuit structure diagram between the interface assembly 14 (including the first interface unit 141 and the second interface unit 142), the protocol chip 111, the master control chip 112, the energy storage assembly 12 and the switch switching circuit in the power supply device 10. In FIG. 4, the lines drawn by the same pins of each part are connected together, such as the CC1 pins in the first interface unit 141, the switch switching circuit and the second interface unit 142, which are connected together. The single-function pins on each part in FIG. 4 are connected to the pins on other devices outside the power supply device 10, such as the FB FB pin on the master control chip 112 and the VBUS0 pin on the second interface unit 142. It should be noted that the single-function pin refers to a specific pin on one circuit in the power supply device 10, and the specific pin does not exist on other circuits in the power supply device 10.

[0113] In the embodiment of the present application, after determining that the power supply device fails to handshake with the target device, the power supply device can pull up its own communication signal to successfully handshake between the power supply device and the target device, so as to ensure that the power supply device normally runs to perform the charging and discharging operation, thereby releasing the electric energy for the power load or receiving the electric energy transmitted by the power supply.

[0114] The embodiment of the present application will introduce how the power supply device 10 enters the charging mode or the discharging mode. In an embodiment, the master control chip 112 in the power supply device 10 is further used to detect the type of the target device 30. If it is determined that the type of the target device 30 is a power supply, the running mode of the energy storage assembly 12 is controlled to be the charging mode. If it is determined that the type of the target device 30 is a power load, the running mode of the energy storage assembly 12 is controlled to be the discharging mode.

[0115] Specifically, the master chip 112 in the power supply device 10 can determine the type of the target device 30 connected with the first interface unit 141 or the second interface unit 142 by detecting the interface component of the target device 30 connected with the first interface unit 141 or the second interface unit 142. If it is determined that the type of the target device 30 is a power supply, a charging mode control instruction 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 the charging mode. If it is determined that the type of the target device 30 is a power load, a discharging mode control instruction 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 the discharging mode.

[0116] In the power supply device, the master chip can detect the type of the target device connected therewith, and then control the energy storage component to work in the charging mode or the discharging mode according to the type of the target device, so that the power supply device can correctly enter different working modes, the problem of working mode disorder can be avoided, and the power supply device can not be damaged due to working mode disorder, so that the service life of the power supply device can be prolonged.

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

[0118] The safety management component 13 is further configured to monitor the operation data of the target component, determine whether an abnormality occurs in the power supply device 10 when the energy storage component 12 is in the operation mode according to the operation data, and send a state control signal of the operation mode to the processing chip 11 if an abnormality occurs.

[0119] The target component can be the processing chip 11, the interface component 14 and / or the energy storage component 12 in the power supply device 10. Alternatively, the operation data of the target component can be the working time of the processing chip 11, the interface component 14 and / or the energy storage component 12, and can also be the working state of the processing chip 11, the interface component 14 and / or the energy storage component 12, and of course, can also be other working parameters of the processing chip 11, the interface component 14 and / or the energy storage component 12.

[0120] In one implementation, the safety management component 13 can input the operation data into a pre-trained algorithm model, and the algorithm model determines whether an abnormality occurs in the power supply device 10 when the energy storage component 12 is in the operation mode according to the operation data.

[0121] In another implementation, the safety management component 13 can perform comparison processing according to the operation data, and determine whether an abnormality occurs in the power supply device 10 when the energy storage component 12 is in the operation mode according to the comparison result.

[0122] In the embodiment of the present application, in the case that it is determined that the power supply device 10 is abnormal when the energy storage assembly 12 is in the running mode, the safety management assembly 13 can send a state control signal of the running mode to the processing chip 11, instructing the processing chip 11 to control the energy storage assembly 12 to stop running in the running mode.

[0123] In one embodiment, if the target assembly includes the interface assembly 14, the running data includes the working temperature of the interface assembly 14; the safety management assembly 13 is configured to monitor the working temperature of the interface assembly 14, and determine that the power supply device 10 is abnormal when the energy storage assembly 12 is in the running mode if the working temperature is greater than or equal to a preset temperature threshold.

[0124] In the embodiment of the present application, if the safety management assembly 13 in the power supply device 10 is only connected with the interface assembly 14, the safety management assembly 13 can monitor the working temperature of the interface assembly 14, and determine whether the working temperature is greater than or equal to a preset temperature threshold; if it is determined that the working temperature is greater than or equal to the preset temperature threshold, it is determined that the power supply device 10 is abnormal when the energy storage assembly 12 is in the running mode; otherwise, it is determined that the power supply device 10 is not abnormal when the energy storage assembly 12 is in the running mode.

[0125] Optionally, the above-mentioned preset temperature threshold can be determined by the user, and can also be determined according to historical experience values, which is not limited in the embodiment of the present application.

[0126] In one embodiment, if the target assembly includes the energy storage assembly 12, the running data includes the working current of the energy storage assembly 12; the safety management assembly 13 is configured to monitor the working current of the energy storage assembly 12, and determine that the power supply device 10 is abnormal when the energy storage assembly 12 is in the running mode if the working current is greater than or equal to a preset current threshold.

[0127] In the embodiment of the present application, if the safety management assembly 13 in the power supply device 10 is only connected with the energy storage assembly 12, the safety management assembly 13 can monitor the working current of the energy storage assembly 12, and determine whether the working current is greater than or equal to a preset current threshold; if it is determined that the working current is greater than or equal to the preset current threshold, it is determined that the power supply device 10 is abnormal when the energy storage assembly 12 is in the running mode; otherwise, it is determined that the power supply device 10 is not abnormal when the energy storage assembly 12 is in the running mode.

[0128] Optionally, the above-mentioned preset current threshold can be determined by the user, and can also be determined according to historical experience values, which is not limited in the embodiment of the present application.

[0129] In addition, the safety management component 13 in the power supply device 10 can be connected with the interface component 14 and the energy storage component 12 at the same time, in which case, the safety management component 13 can monitor the working temperature of the interface component 14 and the working current of the energy storage component 12 at the same time, and determine that the power supply device 10 is abnormal when the energy storage component 12 is in the running mode, in the case that the working current is greater than or equal to the preset current threshold, and / or the working temperature is greater than or equal to the preset temperature threshold.

[0130] The technical solution in the embodiments of the present application is that the safety management component in the power supply device is connected with the target component, the target component includes at least one of the interface component and the energy storage component, the safety management component is further used for monitoring the running data of the target component, and determining whether the power supply device is abnormal when the energy storage component is in the running mode according to the running data, and if so, sending a state control signal of the running mode to the processing chip; the safety management component in the power supply device described above can monitor whether the power supply device is abnormal in real time during the working process of the power supply device, and can notify the processing chip to control the start-stop state of the energy storage component running in the charging mode or the discharging mode in time according to the monitoring result, so as to improve the safety of the power supply device during the working process, and solve the safety hidden trouble problem existing in the working process of the power supply device.

[0131] In addition, the embodiments of the present application also provide a power supply system, as shown in FIG. 5, which includes a connection line 20 and the power supply device 10 in any of the above embodiments; the power supply device 10 is connected with the target device 30 through the connection line 20.

[0132] In actual application, the connection line 20 can be a plug-in connection line, and the connection line 20 can be a data line, a fast charging line or a vehicle charging line, etc. Among them, the interface type of one end of the connection line 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 of the other end of the connection line 20 corresponds to the interface type of the target device 30. Optionally, the target device 30 can be a power load or a power supply.

[0133] In one embodiment, as shown in FIG. 6, 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 with one end of the control switch circuit 23, and the other end of the control switch circuit 23 is connected with the second interface component 22;

[0134] The control switch circuit 23 is used for controlling the electric energy to flow from the first interface component 21 to the second interface component 22, or controlling the electric energy to flow from the second interface component 22 to the first interface component 21, in the case that it is determined that the power supply device 10 and the target device 30 complete the communication handshake.

[0135] In the embodiment of the present application, the connection line 20 in the power supply system has the function of data transmission and can also have the function of delivering electric energy, that is, the connection line 20 can be used as a data line and can also be used as a power line. In the process of using the power supply system, the first interface component 21 of the connection line 20 is connected with the first interface unit 141 or the second interface unit 142 of the power supply device 10, and the second interface component 22 of the connection line 20 is connected with the second interface unit 142 or the first interface unit 141 of the power supply device 10.

[0136] In actual application, after the target device 30 is connected with the power supply device 10 through the connection line 20, the power supply device 10 can quickly charge the target device 30 (that is, the power supply device 10 performs a charging operation), or the power supply device can quickly charge the power supply device 10 (that is, the power supply device 10 performs a discharging operation).

[0137] In the embodiment of the present application, the first interface unit 141 or the second interface unit 142 of the power supply device 10 is an L female seat interface component, and correspondingly, the first interface component 21 of the connection line 20 is an L male head interface component; the second interface unit 142 or the first interface unit 141 of the power supply device 10 is a type-c female seat interface component, and correspondingly, the second interface component 22 of the connection line 20 is a type-c male head interface component. In the embodiment of the present application, the first interface component 21 and the second interface component 22 of the connection line 20 can be realized by an interface circuit.

[0138] The control switch circuit 23 in the connection line 20 can control the electric energy to flow from the first interface component 21 of the connection line 20 to the second interface component 22 of the connection line 20, or control the electric energy to flow from the second interface component 22 of the connection line 20 to the first interface component 21 of the connection line 20 in real time. In actual application, in order to save the electric energy consumed by the connection line 20, the control function of the control switch circuit 23 in the connection line 20 only works after the power supply device 10 and the target device 30 successfully communicate and handshake. In the embodiment of the present application, the control switch circuit 23 of the connection line 20 can be realized by a resistor and a MOS tube.

[0139] In one embodiment, as shown in FIG. 7, the connection line 20 further includes a control communication circuit 24; the control communication circuit 24 is connected with 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 through the connection line 20.

[0141] In the embodiment of the present application, one end of the control communication circuit 24 is connected with the first interface component 21 and the control switch circuit 23 respectively, and the other end of the control communication circuit 24 is grounded. Alternatively, after the power supply device 10 and the target device 30 successfully perform the handshake, the control communication circuit 24 can generate the communication handshake success information and send the communication handshake success information to the control switch circuit 23 in the connecting line 20. After receiving the communication handshake success information, the control switch circuit 23 triggers the control function of itself to control the electric energy to flow from the first interface component 21 to the second interface component 22 of the connecting line 20, or to flow from the second interface component 22 to the first interface component 21 of the connecting line 20.

[0142] Please refer to FIG. 8 which is an internal circuit structure diagram of the connecting line 20 in the power supply system. The lines drawn from the same pins in each part of the connecting line 20 are connected together, and the single-function pins in each part are connected with the pins on other devices outside the connecting line 20, such as the pin MOS_G on the control switch circuit 23.

[0143] In the embodiment of the present application, after the power supply device 10 and the target device 30 are connected through the connecting line 20, the control communication circuit 24 in the connecting line 20 can control the power supply device 10 and the target device 30 to perform the handshake. The control communication circuit 24 can also be understood as a circuit for controlling the communication between the first interface component 21 and the second interface component 22 of the connecting line 20. In the embodiment of the present application, the control communication circuit 24 of the connecting line 20 can be realized by a functional chip, a resistor, a capacitor, and a transient voltage suppression diode (TVS).

[0144] In actual application, the power supply device 10 in the power supply system can release the electric energy to the target device 30 or receive the electric energy from the target device 30 through the connecting line 20 in the power supply system, that is, the connecting line 20 in the power supply system is a multifunctional connecting line 20 which has the function of bidirectional transmission of electric energy or data.

[0145] In the embodiment of the present application, the connecting line 20 is provided with two control circuits (the control switch circuit 23 and the control communication circuit 24), so that the connecting line 20 has the function of double communication security guarantee. The connecting line 20 can not only control the power supply device 10 and the target device 30 in the power supply system to perform the handshake, but also control the transmission of electric energy between the power supply device 10 and the target device 30, so that the power supply device 10 and the target device 30 can be safely connected and operated.

[0146] The power supply system in the embodiments of the present application comprises a power supply device and a connecting line. In actual application, the power supply device and the connecting line can be connected with different types of target devices through the connecting line, so that the power supply device can supply power to the target devices or charge itself, thereby improving the use scenarios of the power supply device and the connecting line. Meanwhile, the power supply device used in the power supply system can timely interrupt the working state of the power supply device when an abnormality occurs in the working process of the power supply device, thereby improving the safety of the power supply device in the working process and solving the safety hazards in the working process of the power supply device. Meanwhile, on the basis of the high safety of the power supply device in the working process, the power supply system can improve the wide applicability, prolong the service life of the power supply device and reduce the maintenance cost of the power supply device.

[0147] The embodiments of the present application provide a control method. The method is applied to a safety management component in the power supply device in any of the above embodiments. As shown in FIG. 9, the method can comprise the following steps:

[0148] S100, monitoring the power supply device when the energy storage component in the power supply device is in a running mode.

[0149] In actual application, the safety management component monitors whether an abnormality occurs in the power supply device when the energy storage component is in the running mode. Correspondingly, if the safety management component outputs an alarm signal, it can be determined that an abnormality occurs in the power supply device when the energy storage component is in the running mode. If the safety management component does not output an alarm signal, it can be determined that no abnormality occurs in the power supply device when the energy storage component is in the running mode.

[0150] In one embodiment, the energy storage component in the power supply device is in the running mode under the control of the master chip in the power supply device when the master chip in the power supply device determines that the power supply device and the target device complete the communication handshake.

[0151] It should be noted that the master chip in the power supply device can detect whether the power supply device and the target device are physically connected. The master chip can detect whether the corresponding pins on the interface unit (the first interface unit or the second interface unit) connected with the target device are in contact to determine whether the power supply device and the target device are physically connected.

[0152] If the corresponding pins on the interface unit connected with the target device are in contact, it is determined that the power supply device and the target device are physically connected. If the corresponding pins on the interface unit connected with the target device are not in contact or are not completely in contact, it is determined that the power supply device and the target device are not physically connected.

[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.
