As shown in fig. 1, the backup power supply device 100 includes a first connection port 101, a second connection port 102, a power transmission management circuit 103, a first switch 111, a second switch 112, a third switch 113, a charging/discharging device 120, a battery device 130, and a controller 140.
In terms of architecture, the power transmission management circuit 103 is electrically connected to the first connection port 101 and the second connection port 102, the first switch 111 is electrically connected to the first connection port 101, the second switch 112 is electrically connected to the second connection port 102, and the second switch 112 is serially connected to the first switch 111.

The battery device 130 is electrically connected to the charging and discharging device 120, and the controller 140 is electrically connected to the power transmission management circuit 103, the first switch 111, the second switch 112, the third switch 113, and the charging and discharging device 120.
For example, the backup Power device 100 may be a mobile Power source (Power Bank), the Power transmission management circuit 103 may be a Power transmission integrated circuit (Power Delivery IC), the first interface 101 may be a Micro USB interface, a USB Type-C interface, or other interfaces, the second interface 102 may be a USB interface, a USB Type-C interface, a Lightning interface, or other interfaces, the first switch 111, the second switch 112, and the third switch 113 may be metal oxide semiconductor field effect transistor (MOS) switches, the charging and discharging device 120 includes a charging and discharging device 121 (e.g., a dc-dc converter) and a Battery Direct Charger (Battery Direct Charger)122, the Battery device 130 may be a chargeable and dischargeable Battery or other Power storage components, and the controller 140 may be a microcontroller, a processor, or other circuits.
In use, the first connection port 101 is connected to a power Adapter (Adapter)190, and the second connection port 102 is connected to the electronic device 170. For example, the electronic device 170 may be a mobile phone, a tablet computer, a notebook computer, or other electronic products.
In an embodiment of the invention, the power adapter 190 can convert the commercial power into the direct current, and when the first connection port 101 is connected to the power adapter 190 but the second connection port 102 is not connected to the electronic device 170, the controller 140 turns on the first switch 111 and the third switch 113 and turns off the second switch 112, so that the charging and discharging device 120 receives the power from the power adapter 190 to charge the battery device 130. Thereby, the standby power supply device 100 can store the standby power.
Specifically, the standby power supply apparatus 100 is connected to the power adapter 190 through the first connection interface 101 (e.g., USB Type-C interface), so that the standby power supply apparatus 100 and the power adapter 190 can communicate with a charging handshake protocol (e.g., PD3.0(PPS) protocol), thereby establishing a signal connection. The power transmission management circuit 103 of the backup power supply apparatus 100 acquires the power supply capability information provided by the power transmission management circuit 193 of the power adapter 190, and the controller 140 selects the charger/discharger 121 or the battery direct charger 122 to charge the battery apparatus 130 based on the power supply capability information of the power adapter 190.
In another embodiment of the present invention, when the electronic device 170 is connected to the second connection port 102 but the power adapter 190 is not connected to the first connection port 101, the controller 140 turns on the second switch 112 and the third switch 113 and turns off the first switch 111, so that the charging and discharging device 120 discharges the battery device 130 to charge the electronic device 170. Thereby, the electronic device 170 is charged with the standby power stored in the standby power supply device 100.
Specifically, the backup power device 100 is connected to the electronic device 170 through the second connection port 102 (e.g., USB Type-C interface) to enable the backup power device 100 and the electronic device 170 to communicate with a charging handshake protocol (e.g., PD3.0(PPS) protocol, USB2.0 HID protocol …, etc.) to establish a signal connection. For example, the controller 140 and the controller 174 may communicate via the PD3.0 protocol, and the power transmission management circuit 103 and the power transmission management circuit 173 may communicate via the PD3.0 protocol. Taking the PD3.0 protocol as an example, the power transmission management circuit 173 of the electronic device 170 obtains the power supply capability information provided by the power transmission management circuit 103 of the backup power device 100, the controller 174 (e.g., SOC) turns on the switch 171, and the controller 174 selects the charger/discharger 175 or the battery direct charger 176 to charge the battery device 177 based on the power supply capability information of the backup power device 100.
In another embodiment of the present invention, when the first connection port 101 is connected to the power adapter 190 and the second connection port 102 is connected to the electronic device 170, the controller 140 can turn on the first switch 111 and the second switch 112, so that the power adapter 190 directly charges the electronic device 170. It should be understood that "directly charging" in the present disclosure means that the power adapter 190 directly charges the electronic device 170 through the first switch 111 and the second switch 112, without the need for the power adapter 190 to first charge the battery device 130 and then charge the electronic device 170 through the battery device 130.
Specifically, the standby power device 100 is connected to the power adapter 190 through the first connection port 101 (e.g., USB Type-C interface), and the standby power device 100 is connected to the electronic device 170 through the second connection port 102 (e.g., USB Type-C interface), so that the power transmission management circuit 103 obtains the power supply capability information of the power adapter 190 provided by the power transmission management circuit 193 and obtains the power receiving capability information, the current power information, the power on/off information …, and the like of the electronic device 170 provided by the power transmission management circuit 173, by using the standby power device 100, the power adapter 190, and the electronic device 170 to communicate with a charging handshake protocol (e.g., PD3.0(PPS) protocol). Under the condition that the power of the electronic device 170 is insufficient, the controller 140 turns on the first switch 111 and the second switch 112, so that the power adapter 190 directly charges the electronic device 170.
To further illustrate the operation method of the backup power device 100, please refer to fig. 1-2, and fig. 2 is a flowchart of an operation method 200 of the backup power device 100 according to an embodiment of the invention. As shown in fig. 2, the operation method 200 includes steps S210 to S270 (it should be understood that the steps mentioned in the embodiment, except for the specific sequence, can be performed simultaneously or partially simultaneously according to the actual requirement.
When the first connection port 101 is connected to the power adapter 190 and the second connection port 102 is connected to the electronic device 170, in step S210, it is determined whether the electric quantity of the electronic device 170 is greater than the first preset electric quantity and the electric quantity of the battery device 130 is greater than the second preset electric quantity, or whether the electronic device 170 is powered off and charged. It should be understood that "power" herein may refer to relative power (e.g., percentage of power), for example, the first predetermined power may be about 80%, and the second predetermined power may be about 80%, but not limited thereto.
When the power of the electronic device 170 is greater than the first preset power and the power of the battery device 130 is greater than the second preset power, which represents the problem that the power of the electronic device 170 and the battery device 130 is not insufficient currently, or when the electronic device 170 is powered off for charging, in step S250, the first switch 111, the second switch 112 and the third switch 113 are turned on, so that the power adapter 190 directly charges the electronic device 170, and the charging and discharging device 120 receives the power from the power adapter 190 to charge the battery device 130.
On the other hand, when the condition that the electric quantity of the electronic device 170 is greater than the first predetermined electric quantity and the electric quantity of the battery device 130 is greater than the second predetermined electric quantity is not satisfied, or when the electronic device 170 is powered on for charging, a further determination is made, so in step S220, it is determined whether the electric quantity of the electronic device 170 minus the electric quantity of the battery device 130 is greater than a third predetermined electric quantity, or whether the electric quantity of the electronic device 170 is fully charged (e.g., the electric quantity is 100%). For example, the third predetermined amount of power may be about 10%, but the disclosure is not limited thereto.
When the power of the electronic device 170 minus the power of the battery device 130 is not greater than the third predetermined power, or when the electronic device 170 is not fully charged, which means that the power of the electronic device 170 is relatively insufficient, the electronic device 170 needs to be charged first, in step S230, the first switch 111 and the second switch 112 are turned on, and the third switch 113 is turned off, so that the power adapter 190 directly charges the electronic device 170.
After the power adapter 190 directly charges the electronic device 170, in step S240, it is determined whether the power of the electronic device 170 minus the power of the battery device 130 is greater than a fourth preset power, or whether the power of the electronic device 170 is greater than a fifth preset power. For example, the fourth predetermined amount of power may be about 30%, and the fifth predetermined amount of power may be about 85%, but the disclosure is not limited thereto.
When the power of the electronic device 170 minus the power of the battery device 130 is greater than the fourth preset power or the power of the electronic device 170 is greater than the fifth preset power, which represents the problem that the current power of the electronic device 170 is not enough, the process returns to step S210 to determine whether the power of the electronic device 170 is greater than the first preset power and the power of the battery device 130 is greater than the second preset power again.
On the other hand, when the power of the electronic device 170 minus the power of the battery device 130 is greater than the third predetermined power, or when the electronic device 170 is fully charged, which means that the power of the electronic device 170 is sufficient, the standby power device 100 can be charged preferentially, and in step S260, the first switch 111 and the third switch 113 are turned on, and the second switch 112 is turned off, so that the charging and discharging device 120 receives the power from the power adapter 190 to charge the battery device 130.
After the charging and discharging device 120 receives the power from the power adapter 190 to charge the battery device 130, in step S270, it is determined whether the power of the electronic device 170 is less than or equal to the power of the battery device 130.
When the power of the electronic device 170 is less than or equal to the power of the battery device 130, which indicates that the power of the electronic device 170 may be insufficient, the process returns to step S210 to determine whether the power of the electronic device 170 is greater than the first predetermined power and the power of the battery device 130 is greater than the second predetermined power.
When the power of the electronic device 170 is less than or equal to the power of the battery device 130, it means that the charging/discharging device 120 still receives the power from the power adapter 190 to charge the battery device 130 until the power of the electronic device 170 is less than or equal to the power of the battery device 130.
In conclusion, compared with the prior art, the technical scheme of the invention has obvious advantages and beneficial effects. According to the technical scheme of the invention, the first switch 111, the second switch 112 and the third switch 113 are used for realizing the standby power supply device 100 with the direct charging function, and the technical scheme can adjust the energy distribution between the standby power supply device 100 and the electronic device 170.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
