The above described objects, features, and characteristics of the present invention will become more apparent from the aspects of the invention.

Please refer to FIG. 1 and FIG. 2 simultaneously. FIG. 1 is a schematic diagram of a vehicle charging device with a power supply applied to a jack of a vehicle power supply and connected to an electronic device according to an embodiment of the present invention; FIG. 2 is a vehicle with a power supply of FIG. A block diagram of a backup power supply unit using a charging device.

As shown in FIGS. 1 and 2, a vehicle charging device 1 including a power source includes a vehicle charger 10 and a backup power source device 12.

The vehicle charger 10 includes a vehicle power input terminal 100a and a power source output terminal 100b. The vehicle power input end 100a is a cigarette lighter plug. The backup power supply device 12 is disposed inside the vehicle charger 10. The backup power supply unit 12 includes an energy storage unit 120 electrically connected to the vehicle power input terminal 100a and the power output terminal 100b.

The energy storage unit 120 can be used to store the electrical energy input through the vehicle power input terminal 100a, and the power output terminal 100b is configured to output the electrical energy stored by the energy storage unit 120.

In detail, the vehicle power input terminal 100a is electrically connected to the vehicle power socket 20 of the vehicle (for example, in the vehicle) (as shown in FIG. 1); the power output terminal 100b is electrically connected to the electronic device. 30. For example, the power output terminal 100b can be electrically connected to the electronic device 30 through the connection line 40. The electronic device 30 may be an electronic product such as a driving recorder or a mobile phone, but is not limited thereto.

It can be seen that after the vehicle is started and the vehicle power input terminal 100a is plugged into the vehicle power socket 20, a power converter inside the vehicle charger 10 can supply the power provided by the vehicle power socket 20. Converted (for example, the power converter can convert 12 volts (V) into 5 volts (V), but this is for illustrative purposes only, and is not limited thereto), after which the converted power supply device 12 can be used for conversion. The electrical energy is stored to the energy storage unit 120.

In other words, the energy storage unit 120 can store the electrical energy input via the vehicle power input terminal 100a; and the power output terminal 100b can be used to output the electrical energy stored by the energy storage unit 120 to the electronic device 30 to charge the electronic device 30.

Therefore, after the vehicle is turned off or the vehicle power input terminal 100a of the vehicle charger 10 is removed from the vehicle power source jack 20, the electric energy stored in the energy storage unit 120 can continue to be performed on the electronic device 30. Charging so that the user can continue to use the electronic device.

Specifically, the backup power supply device 12 further includes a power input circuit 121, a control circuit 122, and a power output circuit 123.

In addition, the power output circuit 123 is electrically connected to the power output terminal 100b, and the power output terminal 100b may include a USB (Universal Serial Bus (USB)) interface. In other words, the connection line 40 may be a USB transmission line, but is not limited. herein.

When the stored energy of the energy storage unit 120 is greater than the first set value, the control circuit 122 controls the power input circuit 121 not to perform the electrical energy storage to The energy storage unit 120 prevents the energy storage unit 120 from being charged. For example, when the energy stored in the energy storage unit 120 is greater than 80%, but not limited thereto, the control circuit 122 controls the power input circuit 121 not to store the electrical energy to the energy storage unit 120 to enhance the energy storage unit. 120 lifetime.

Alternatively, when the stored energy of the energy storage unit 120 is less than the second set value, the control circuit 122 controls the power output circuit 123 not to output the energy stored by the energy storage unit 120 to the power output terminal 100b, so that the energy storage unit 120 cannot supply power. . For example, when the energy stored in the energy storage unit 120 is less than 20%, but not limited thereto, the control circuit 122 controls the power output circuit 123 not to output the energy stored in the energy storage unit 120 to the electronic device 30. The service life of the energy storage unit 120 is increased.

It should be noted that the first set value and the second set value may be preset values, which may be determined according to actual design requirements of the backup power supply device 12, and are not limited to those disclosed in the embodiment.
