Abstract
Electronic locking devices are provided. One electronic locking device includes a circuit configured to cause a processor of the electronic locking device to be powered by a capacitor, and not a battery for powering a high current load of the electronic locking device, while the battery is driving the high current load of the electronic locking device.
Claims20
An electronic locking device comprising:
- a circuit configured to cause a processor of the electronic locking device to be powered by a capacitor, and not a battery for powering a high current load of the electronic locking device, while the battery is driving the high current load of the electronic locking device.
An electronic locking device comprising:
- a battery;
- a processor;
- a capacitor that is electrically coupled to the processor;
- a load;
- and
- at least one switching device, wherein the at least one switching device is controllable by control signals received from the processor to place the at least one switching device in one of a plurality of configurations,
- wherein, in a first configuration, the at least one switching device is configured to electrically isolate the load from the battery and connect the battery to the capacitor to charge the capacitor, and
- wherein, in a second configuration, the at least one switching device is configured to connect the load to the battery and electrically isolate the capacitor and the processor from the battery and the load, wherein the processor is powered by the capacitor in the second configuration.

An electronic locking device comprising:
- a battery;
- a processor configured to control a position of a first switch and a position of a second switch;
- a capacitor, wherein the capacitor is connected in parallel with the processor;
- a high current load;
- the first switch configured to:
- connect, in a closed position, the battery to the capacitor and the processor, wherein the battery provides power to the processor and the capacitor when the first switch is in the closed position;
- and
- disconnect, in an open position, the battery from the capacitor and the processor, wherein the capacitor is configured to provide power to the processor when the first switch is the open position;
- and
- the second switch configured to:
- connect, in a closed position, the battery to the high current load, wherein the battery provides power to the high current load when the second switch is in the closed position;
- and
- disconnect, in an open position, the battery from the high current load.
