The number of the one or more charging mode display lamps 105 is not limited (only 3 are illustrated in fig. 1). The one or more charging mode display lamps 105 may be light-emitting diodes (LEDs) or the like. Without limitation.

The charging mode refers to the output power of the power supply equipment, and one charging mode corresponds to one output power.

For example, when the output of the power control circuit 100 outputs a first power value, one or more of the charge mode display lamps 105 may be in a first charge mode display state. When the output of the power control circuit 100 outputs the second power value, the one or more charging mode display lamps 105 may be in the second charging mode display state. When the output of the power control circuit 100 outputs the third power value, the one or more charging mode display lamps 105 may be in a third charging mode display state.

For example, when the number of the one or more charging mode display lamps 105 is one, one charging mode display lamp may display different colors according to different charging modes. For example, when the one or more charging mode display lamps 105 are in the first charging mode display state, the one or more charging mode display lamps 105 may display a red color; when the one or more charging mode display lamps 105 are in the second charging mode display state, the one or more charging mode display lamps 105 may display green; when the one or more charging mode display lamps 105 are in the third charging mode display state, the one or more charging mode display lamps 105 may display yellow.

For another example, when the number of the one or more charging mode display lamps 105 is plural, the plurality of charging mode display lamps may display different forms according to different charging modes. For example, when one or more charging mode display lights 105 are in a first charging mode display state, the plurality of charging mode display lights may be in a normally on state; when one or more charging mode display lamps 105 are in the second charging mode display state, the display form of the charging mode display lamps may be a breathing mode; when one or more of the charging mode display lamps 105 is in the third charging mode display state, the plurality of charging mode display lamps may be displayed in a ticker mode. The breathing mode means that the plurality of charging mode display lamps may be simultaneously lighted or simultaneously extinguished at time intervals. The ticker mode means that the plurality of charging mode display lamps may be sequentially turned on or off at time intervals.

For another example, when the number of the one or more charging mode indicator lamps 105 is plural, one of the charging mode indicator lamps corresponds to one charging mode. For example, the number of the plurality of charge mode indicator lamps is 3, and the plurality of charge mode indicator lamps are charge mode indicator lamp 1, charge mode indicator lamp 2, and charge mode indicator lamp 3, respectively. When one or more of the charging mode display lamps 105 are in the first charging mode display state, the charging mode display lamp 1 emits light, and the charging mode display lamp 2 and the charging mode display lamp 3 are turned off; when one or more of the charging mode display lamps 105 are in the second charging mode display state, the charging mode display lamp 2 emits light, and the charging mode display lamp 1 and the charging mode display lamp 3 are turned off; when one or more of the charging mode display lamps 105 are in the third charging mode display state, the charging mode display lamp 3 emits light, and the charging mode display lamp 1 and the charging mode display lamp 2 are turned off.

For another example, in the embodiment of the present application, each charging mode may correspond to a plurality of charging mode display lamps. As shown in fig. 6a, a plurality of charging mode display lamps corresponding to a first charging mode are provided in the embodiment of the present application. As shown in fig. 6b, a plurality of charging mode display lamps corresponding to a second charging mode are provided in the embodiment of the present application. As shown in fig. 6c, a plurality of charging mode display lamps corresponding to a third charging mode provided in the embodiment of the present application are provided.

Wherein, when the plurality of charging mode display lamps in fig. 6a emit light, it represents in the first charging mode; when the plurality of charging mode indicator lights in fig. 6b are illuminated, they are shown in a second charging mode; when the plurality of charging mode indicator lights in fig. 6c are illuminated, it is indicated as being in the third charging mode. The connection relationship of the multiple charging mode display lamps in fig. 6a, fig. 6b, and fig. 6c and the signals and the sizes (resistors, capacitors, MOS transistors) of the connected components may be as shown in the figures, which is not described again.

The control module 101 may be configured to control one or more output ends of each power control circuit to output a power value corresponding to an operation instruction according to the operation instruction of the first control switch 103 and/or the second control switch 104, and control one or more charging mode display lamps 105 to display a charging state corresponding to the operation instruction.

The charging display state means that one or more charging mode display lamps 105 can be turned on or off in response to an operation instruction of the control switch. A charging mode corresponds to a charging display state.

For example, taking the circuit diagram shown in fig. 1 as an example, the control module 101 may be configured to control the first output terminal, the second output terminal, the third output terminal, the fourth output terminal, and the fifth output terminal to output the power value corresponding to the operation instruction according to the operation instruction of the first control switch 103 and/or the second control switch 104.

Specifically, in response to the first operation instruction of the first control switch 103, the control module 101 may control the first output terminal, the second output terminal, the third output terminal, the fourth output terminal, and the fifth output terminal to output the first power value, and control the one or more charging mode display lamps 105 to be in the first charging display state. Alternatively, in response to the first operation instruction of the first control switch 103 and the second operation instruction of the second control switch 104, the control mode 101 may control the first output terminal, the second output terminal, the third output terminal, the fourth output terminal, and the fifth output terminal to output the second power value, and control the one or more charging mode display lamps 105 to be in the second charging display state. Alternatively, in response to the first operation instruction of the first control switch 103 and the third operation instruction of the second control switch 104, the control mode 101 may control the power values output by the first output terminal, the third output terminal, and the fifth output terminal to be 0, control the second output terminal and the fourth output terminal to output the third power value, and control the one or more charging mode display lamps 105 to be in the third charging display state. Wherein the first power level, the second power level, and the third power level may be set as desired, for example, the first power level may be 5 watts (W) (5V1A), the second power level may be 7W (5V1.4A), and the third power level may be 18W (5V3A &9V2A &12 V1.5A). Without limitation.

The first operation instruction may refer to an operation instruction triggered when the user presses the first control switch 103. The second operation instruction and the third operation instruction may refer to operation instructions that are triggered when the user presses the second control switch 104. The second operation instruction and the third operation instruction are different.

For example, when the user presses the first control switch 103, the power control circuit 100 may be brought into communication with the battery pack, at which time the plurality of output terminals of the power control circuit 100 output the first power value. When the user presses the first control switch 103 again, the power control circuit 100 may be disconnected from the battery pack, and the power values output by the plurality of output terminals of the power control circuit 100 at this time are 0. That is, the power control circuit 100 is in the first charging mode (which may also be referred to as an on-black mode).

For another example, when the user presses the first control switch 103, the number of times that the user presses the second control switch 104 is the first value, the power control circuit 100 may be triggered to communicate with the battery pack, and the plurality of output terminals of the power control circuit 100 output the second power value. That is, the power control circuit 100 is in the second charging mode (which may also be referred to as the balancing mode).

For another example, when the user presses the first control switch 103, the number of times that the user presses the second control switch 104 is the second value, the power control circuit 100 may be triggered to communicate with the battery pack, the power values output by the first output terminal, the third output terminal, and the fifth output terminal of the power control circuit 100 are 0, and the third power value is output by the second output terminal and the fourth output terminal. That is, the power supply control circuit 100 is in the third charging mode (may also be referred to as a spark collecting mode). The first value and the second value are different, for example, the first value may be an odd number, and the second value may be an even number.

It should be noted that the three charging modes can be switched, for example, the control module 101 can determine the charging mode of the power control circuit 100 according to the number of times that the user presses the second control switch 104. For example, when the power supply control circuit 100 is in the first charging mode, the power supply control circuit 100 may be switched to the second charging mode in response to one pressing operation of the second control switch 104 by the user; when the power supply control circuit 100 is in the second charging mode, the power supply control circuit 100 may be switched to the third charging mode in response to one pressing operation of the second control switch 104 by the user; when the power supply control circuit 100 is in the third charging mode, the power supply control circuit 100 may be switched to the third charging mode in response to one pressing operation of the second control switch 104 by the user.
