[0002] Currently, an increasing number of devices on the market require fast charging capabilities. However, some charging devices are only equipped with a single output port, meaning that when users need to charge multiple devices simultaneously, they can only charge them one by one. This not only significantly extends the total charging time but also reduces overall charging efficiency. Furthermore, when the load requires high power, a single charging device cannot support high-power charging, again resulting in low charging efficiency and a poor user experience.

[0028] This utility model embodiment provides a bidirectional output charging device. Figure 1 This is a schematic diagram of the structure of a bidirectional output charging device provided in an embodiment of the present invention, with reference to... Figure 1 The charging device includes a first interface 10 and at least two second interfaces 20. The first interface 10 is connected to a charging device, and the second interfaces 20 are connected to a load; alternatively, the first interface 10 is connected to a load, and the second interfaces 20 are connected to a charging device. Multiple second interfaces 20 can be connected to either a load or a charging device simultaneously. The charging device may include a charger or a power bank. For example, when the first interface 10 is connected to a charging device and multiple second interfaces 20 are connected to loads, multiple loads can be charged simultaneously using a single charging device. When the first interface 10 is connected to a load and multiple second interfaces 20 are connected to charging devices, multiple charging devices can simultaneously provide high-power power to the loads, thereby improving the charging efficiency of high-power loads. Figure 1 The example provided shows a charging device including three second interfaces 20.

[0029] The charging device also includes a voltage conversion module 30 and a control module 40.

[0030] The voltage conversion module 30 has one end connected to the first interface 10 and the other end connected to the second interface 20. The control module 40 is connected to the first interface 10, the second interface 20, and the voltage conversion module 30. The control module 40 acquires power information of the devices connected to the first interface 10 and each of the second interfaces 20, and outputs a power output control signal. The voltage conversion module 30 can be electrically connected to the first interface 10 and each of the second interfaces 20, and can also be communicatively connected to the control module 40. The first interface 10 and each of the second interfaces 20 can also be communicatively connected to the control module 40.

[0031] The power information includes at least one of the voltage, current, or power of the device connected to the corresponding interface. Here, voltage, current, and power can all be calibrated values. When a charging device is connected to the first interface 10 and a load is connected to each of the second interfaces 20, the control module 40 acquires the output power information of the charging device connected to the first interface 10 and the output power information of each of the second interfaces 20. When a charging device is connected to each of the second interfaces 20 and a load is connected to the first interface 10, the control module 40 acquires the output power information of the charging device connected to each of the second interfaces 20 and the output power information of the first interface 10.

[0032] Specifically, since the control module 40 is connected to the first interface 10, each of the second interfaces 20, and the voltage conversion module 30, when a charging device is connected to the first interface 10 and a load is connected to each of the second interfaces 20, the control module 40 can obtain the output power information of the charging device and control the charging device to output at maximum power. Simultaneously, the control module 40 obtains the power information required by the load connected to each of the second interfaces 20, i.e., the output power information of each of the second interfaces 20. Then, the control module 40 outputs a corresponding power output control signal, and the voltage conversion module 30 receives the power output control signal and performs voltage conversion to meet the charging needs of each load. Similarly, when a charging device is connected to each of the second interfaces 20 and a load is connected to the first interface 10, the control module 40 can obtain the output power information of each charging device and control each charging device to output at maximum power. The control module 40 obtains the power information required by the load, i.e., the output power information of the first interface 10. Then, the control module 40 outputs a corresponding power output control signal, and the voltage conversion module 30 receives the power output control signal and performs voltage conversion to meet the charging needs of the load.

[0033] The technical solution of this utility model embodiment includes a charging device comprising a first interface 10 and at least two second interfaces 20. When multiple second interfaces 20 are connected to a load, the first interface 10 is connected to the charging device; conversely, when multiple second interfaces 20 are connected to the charging device, the first interface 10 is connected to the load. Furthermore, the charging device also includes a voltage conversion module 30 and a control module 40. The control module 40 acquires the power information of the first interface 10 and each second interface 20 and outputs a power output control signal. The voltage conversion module 30 receives the power output control signal and performs voltage conversion on the interfaces connected to the load to ensure the charging needs of the load are met. In summary, this utility model embodiment can not only enable simultaneous charging of multiple loads with a single charging device, but also enable simultaneous power supply to a single load with multiple devices, especially suitable for supplying power to high-power loads. Furthermore, based on the power information of each interface, the control module 40 controls the voltage conversion module 30 to convert or distribute the power input to the charging device, improving charging efficiency to ensure the charging needs of high-power loads are met, thereby enhancing the user experience.

[0034] Optionally, based on the above embodiments, at least one of the first interface 10 and at least two second interfaces 20 is a Type-C interface. By setting at least one interface in the charging device to a Type-C interface, its versatility can be improved.

[0035] Figure 2 A schematic diagram of another bidirectional output charging device provided in an embodiment of this utility model is shown below. Figure 2 Based on the above embodiments, optionally, the voltage conversion module 30 includes at least two voltage conversion units, the first ends of which are connected to the first interface 10, and the second ends of which are respectively connected to a second interface 20; wherein, one voltage conversion unit is connected to one second interface 20 in a one-to-one correspondence. By setting the voltage conversion units to be connected to the second interfaces 20 in a one-to-one correspondence, the voltage conversion unit of each interface can work independently, and the voltage and / or current of each second interface 20 can be individually adjusted, thereby meeting the charging or discharging requirements of various devices and improving its versatility. At the same time, when each second interface 20 is connected to a load, this setting can also ensure that each second interface 20 is charged at its optimal voltage and current, thereby achieving fast charging and improving charging efficiency. And when each second interface 20 is connected to a charging device, its output power can be adjusted according to the power requirements of the load connected to the first interface 10, avoiding unnecessary energy waste and improving the overall energy utilization rate.

[0036] Continue to refer to Figure 2Optionally, there are two second interfaces 20, and the voltage conversion module 30 includes a first voltage conversion unit 31 and a second voltage conversion unit 32. Both the first voltage conversion unit 31 and the second voltage conversion unit 32 are connected to the control module 40. The first voltage conversion unit 31 is connected between the first interface 10 and one second interface 20, and the second voltage conversion unit 32 is connected between the first interface 10 and another second interface 20. The first voltage conversion unit 31 and the second voltage conversion unit 32 are respectively used to control the output power of the corresponding connected second interface 20.

[0037] Continue to refer to Figure 2 Optionally, the voltage conversion unit includes a DC / DC converter. The DC / DC converter is used to convert the input DC voltage into the desired output DC voltage. By including a DC / DC converter in the voltage conversion unit, its voltage conversion efficiency is improved.

[0038] Figure 3 A schematic diagram of another bidirectional output charging device provided in an embodiment of this utility model is shown below. Figure 3 Based on the above embodiments, optionally, the control module 40 includes a first control unit 41 and a second control unit 42, with the first control unit 41 connected to the second control unit 42. The first control unit 41 is connected to the first interface 10, and the second control unit 42 is connected to at least two second interfaces 20 and the voltage conversion module 30, respectively. The first control unit 41 and the second control unit 42 can be connected in communication.

[0039] Specifically, when a charging device is connected to the first interface 10 and a load is connected to each of the second interfaces 20, the first control unit 41 communicates with the first interface 10 to obtain the output power information of the charging device at the first interface 10, and controls the charging device to output at maximum power. The first control unit 41 transmits this power information to the second control unit 42. At the same time, the second control unit 42 communicates with each of the second interfaces 20 to obtain the power information required by the load at each of the second interfaces 20. Then, the second control unit 42 outputs a power output control signal based on the output power information at the first interface 10 and the second interface 20. After receiving the power output control signal, the first voltage conversion unit 31 and the second voltage conversion unit 32 perform voltage conversion respectively, so that the loads connected to each of the second interfaces 20 are charged with optimal voltage and current, thereby realizing simultaneous fast charging of each load.

[0040] When a load is connected to the first interface 10 and charging devices are connected to each of the second interfaces 20, the second control unit 42 communicates with each of the second interfaces 20 to obtain the output power information of the charging devices at each of the second interfaces 20, and controls each charging device to output at maximum power. The second control unit 42 transmits the power information to the first control unit 41. At the same time, the first control unit 41 communicates with the first interface 10 to obtain the power information required by the load at the first interface 10. Then, the first control unit 41 outputs a power output control signal based on the power information at the first interface 10 and the second interface 20, and transmits it to the second control unit 42. After receiving the power output control signal, the first voltage conversion unit 31 and the second voltage conversion unit 32 perform voltage conversion respectively, so that the load connected to the first interface 10 is charged with optimal voltage and current, thereby realizing high-power charging of the load.

Figure 4 Optionally, based on the above embodiments, the charging device further includes a mode control module 50. The mode control module 50 is connected to the control module 40 and is used to configure the charging mode of the charging device, wherein the charging mode includes a single-port input charging mode and a multi-port input charging mode.

[0042] The single-port input charging mode specifically involves connecting the first interface 10 to the charging device and multiple second interfaces 20 to the load. The multi-port input charging mode specifically involves connecting multiple second interfaces 20 to the charging device and the first interface 10 to the load. By setting the mode control module 50, the charging mode of the charging device can be adjusted according to actual needs, meeting the requirements of different devices and scenarios, thereby improving charging efficiency.

[0043] Optionally, the mode control module 50 includes a button connected to the control module 40. By including a button in the mode control module 50 to configure the charging mode of the charging device via the button, the circuit structure can be simplified and the cost reduced.
