Emergency charging device and method for door lock
The present invention relates to an emergency charging device and method for a door lock and specifically to an emergency charging device and method for a door lock, capable of: charging a secondary battery by means of light or a battery in a regular charging mode in which the battery is not discharged and, at the same time, operating the door lock by means of the battery or the secondary battery according to the amount of charge; and operating the door lock in an emergency manner by urgently charging the secondary battery by means of light in an emergency charging mode in which the battery is discharged.
1. An emergency charging device for a door lock, comprising:
a solar cell module configured to receive external light and to output a voltage;
a secondary battery configured to receive the voltage outputted from the solar cell module, and to store an electricity; and
a door lock control unit configured to control an operation of the door lock by using electric energy supplied from the secondary battery.
2. The emergency charging device of claim 1 , further comprising a primary battery,
wherein, when an amount of electricity stored in the secondary battery is greater than or equal to a set maximum amount of charge, the door lock control unit is configured to operate the secondary battery as an operating power source of the door lock, and, when the amount of electricity of the secondary battery is less than or equal to the set maximum amount of charge, the door lock control unit is configured to operate the primary battery as the operating power source of the door lock.
3. The emergency charging device of claim 2 , wherein, when the amount of electricity stored in the secondary battery is less than or equal to a set minimum amount of charge, the door lock control unit is configured to charge the secondary battery by using a voltage of the primary voltage.
4. The emergency charging device of claim 2 , wherein, when the primary battery is discharged and the amount of electricity stored in the secondary battery is greater than or equal to a set minimum amount of charge, the door lock control unit is configured to operate the secondary battery as the operating power source of the door lock.
5. The emergency charging device of claim 2 , wherein, when the primary battery is discharged and the amount of electricity stored in the secondary battery is less than or equal to a set minimum amount of charge, the door lock control unit is configured to receive the voltage from the solar cell module, and to charge the secondary battery, and, when the amount of electricity stored in the secondary battery is greater than or equal to the set minimum amount of charge, the door lock control unit is configured to operate the secondary battery as the operating power source of the door lock.
6. The emergency charging device of claim 2 , further comprising a charging control unit configured to adjust the voltage outputted from the primary battery or the solar cell module to a rechargeable voltage, and to apply the voltage to the secondary battery.
7. An emergency charging method for a door lock, the method comprising the steps of:
charging a secondary battery by using an output voltage of a solar cell module in a regular charging mode in which a primary battery is not discharged;
when an amount of electricity stored in the secondary battery is greater than or equal to a set maximum amount of charge, operating the secondary battery as an operating power source of the door lock;
when the amount of electricity stored in the secondary battery is less than or equal to the set maximum amount of charge, operating the primary battery as the operating power source of the door lock; and
when the primary battery is not discharged and the amount of electricity stored in the secondary battery is less than or equal to a set minimum amount of charge, charging the second battery by using an output voltage of the primary battery.
8. The emergency charging method of claim 7 , further comprising a step of, when the amount of electricity stored in the secondary battery is greater than or equal to the set minimum amount of charge in an emergency charging mode in which the primary battery is discharged, operating the second battery as the operating power source of the door lock.
9. The emergency charging method of claim 7 , further comprising the steps of:
when the amount of electricity stored in the secondary battery is less than or equal to the set minimum amount of charge in an emergency charging mode in which the primary battery is discharged, and there is an output voltage from the solar cell module, charging the secondary battery by using the output voltage of the solar cell module; and
when the amount of electricity stored in the secondary battery is greater than or equal to the set minimum amount of charge, operating the secondary battery as the operating power source of the door lock.
