Multi-use fast rate charging stand
View Patent ↗An apparatus includes a charger and a plurality of connectors such that a connector includes a switch and a connection between the charger and the connector. The charger is configured to direct a switch associated with one of the plurality of connectors to connect the connector with which it is associated to the charger. The charger is also configured to charge a device connected to the connector according to a type of battery detected in the device. A plurality of devices is charged using a prioritized charging scheme.
1. An apparatus comprising:
a plurality of connectors within a multiport charging dock, wherein each connector is configured to receive a device including a rechargeable battery;
a charger, coupled to the plurality of connectors, to charge the battery of each device connected to one of the plurality of connectors according to a battery type detected in each of the devices;
a plurality of switches, wherein the plurality of switches are coupled to the plurality of connectors to electrically couple the plurality of connectors to the charger; and
circuitry (i) to control switching of the plurality of switches coupled to the plurality of connectors, (ii) to connect the plurality of connectors to the charger, and (iii) to permit charging current to flow from a variable current source to each device connected to one of the plurality of connectors based upon the battery type identified by a battery type identifier;
wherein the charger charges a plurality of devices using first and second prioritized charging schemes when the plurality of devices are connected to the plurality of connectors,
wherein the first prioritized charging scheme charges batteries in devices in a first subgroup of the plurality of devices over multiple other subgroups of the plurality of devices, and
wherein the second prioritized charging scheme is used to charge batteries in devices within the first subgroup of the plurality of devices.
2. The apparatus of claim 1 , wherein the charger charges the plurality of devices simultaneously when the plurality of devices are connected to respective connectors of the plurality of connectors.
3. The apparatus of claim 1 , wherein the charger charges devices within the first subgroup simultaneously.
4. The apparatus of claim 1 , further comprising a user interface for receiving instructions from a user defining the first and the second prioritized charging schemes.
5. The apparatus of claim 4 , wherein when a first device is connected to a first connector of the plurality of connectors at a first time, and a second device is connected to a second connector of the plurality of connectors at a second time later than the first time, the charger diverts current from the first device to the second device according to relative capacities of batteries associated with the first and the second devices.
6. The apparatus of claim 1 , wherein the charger receives results of an identification of batteries coupled to the plurality of devices and determines one of the first or second prioritized charging schemes using the results.
7. The apparatus of claim 1 , wherein the charger charges the plurality of devices serially according to an order in which the plurality of devices are connected to respective connectors of the plurality of connectors.
8. The apparatus of claim 1 , wherein the charger charges devices according to an ordering of the connectors.
