Abstract

The embodiments of the invention relate to a novel apparatus and method for a battery charging system in a shared environment, as well as for monitoring battery usage and tracking battery location. In one embodiment, the battery charging chute comprises a housing configured to receive a battery via an insertion slot and configured to dispense a battery through a dispensing slot. Within the housing, charging terminals are disposed is a spaced or continuous manner, to come in contact with the charging terminals on batteries inserted into the housing. Optionally, solenoid-controlled gates may be employed at the insertion slot and dispensing slot, to inhibit the removal or insertion of batteries from the incorrect location, to ensure that the battery with the longest residence time in the chute is dispensed to a user. The housing may also include a radio-frequency identification tag reader to permit inventorying and tracking of batteries inserted into the housing.

Claims

1. A battery charging apparatus, comprising:

a housing having an enclosed chute running through a central axis of the housing, the chute configured to permit batteries to pass through the housing, wherein a first end of the housing comprises an insertion slot and a second end of the housing comprises a dispensing slot and the insertion slot and the dispensing slot are configured to permit a rechargeable battery to pass therethrough;

a plurality of battery charging terminals disposed within the chute; and

at least one battery charging controller in electronic communication with the charging terminals,

wherein the chute is of a length sufficient to contain more than one rechargeable battery therein and wherein the battery charging terminals in the chute are configured to contact battery charging terminals disposed on the rechargeable battery.

2. The apparatus of claim 1, further comprising a gate disposed at the insertion slot and configured to prevent the removal of the rechargeable battery from the enclosed chute via the insertion slot.

3. The apparatus of claim 1, further comprising a gate disposed at the dispensing slot and configured to prevent the insertion of the rechargeable battery from the enclosed chute via the dispensing slot.

4. The apparatus of claim 2, wherein the gate is controlled by a solenoid or an electric motor.

5. The apparatus of claim 3, wherein the gate is controlled by a solenoid or an electric motor.

6. The apparatus of claim 1, further comprising a battery identification reader for receiving identification information from identifying indicia on the rechargeable battery.

7. The apparatus of claim 6, wherein the battery identification reader is a radio-frequency identification tag reader.

8. The apparatus of claim 1, further comprising a user identification input device.

9. The apparatus of claim 8, wherein the user identification input device is a bar code scanner or radio frequency identification reader.

10. The apparatus of claim 8, further comprising a computer network interface for transmitting user identification information to a computer.

11. The apparatus of claim 6, further comprising a computer network interface for transmitting batter identification information to a computer.

12. The apparatus of claim 5, wherein the solenoid is controlled by a computer and the computer is configured to actuate a solenoid to open the gate and permit the removal of a rechargeable battery to an authorized user.

13. The apparatus of claim 1, wherein the battery-charging controller is a microcontroller.

14. The apparatus of claim 13, further comprising at least one thermal sensor disposed within the enclosed chute, wherein the at least one thermal sensor is configured to transmit the thermal state of the rechargeable battery to the microcontroller.

15. The apparatus of claim 13, further comprising at least one battery status sensor within the enclosed chute, wherein the at least one battery-status sensor is configured to transmit a status of the rechargeable battery to the microcontroller.

16. The apparatus of claim 11, wherein the microcontroller is configured to regulate a voltage and a current supplied to the battery charging terminals.

17. The apparatus of claim 15, wherein the microcontroller is configured to receive the status of the rechargeable battery and to regulate a voltage and a current supplied to the battery charging terminals.

18. A method for recharging batteries in a shared environment, comprising:

inserting a rechargeable battery into a housing having an enclosed chute running through a central axis of the housing and a plurality of battery charging terminals disposed within the chute, the chute configured to permit the rechargeable battery to pass through the housing,

wherein the housing is configured to receive and charge a plurality of individual rechargeable batteries; and

charging the rechargeable battery; and

dispensing a charged rechargeable battery;

wherein the charged rechargeable battery has the greatest residence time in the housing of all rechargeable batteries disposed within the housing.

19. The method of claim 18, further comprising scanning the rechargeable battery for identifying indicia.

20. The method of claim 19, further comprising reading information from identifying indicia disposed on the rechargeable battery.

21. The method of claim 20, wherein the identifying indicia includes information to indicate the date when the rechargeable battery was first used.

22. The method of claim 21, further comprising determining whether the rechargeable battery has exceeded its usable life, based on the length of time the rechargeable battery has been in service and/or the number of times the rechargeable battery has been recharged.

23. The method of claim 18, further comprising identifying a user attempting to insert or remove the rechargeable battery to or from the housing.

24. The method of claim 23, comprising determining whether the user is authorized to insert or remove a rechargeable battery from the housing.

25. The method of claim 24, comprising permitting a user to insert or remove a rechargeable battery from the housing.

26. The method of claim 18, further comprising monitoring a status of the rechargeable battery.

27. The method of claim 26, wherein the status includes a temperature of the rechargeable battery.

28. The method of claim 26, wherein the status includes a charge level of the rechargeable battery.

29. The method of claim 28, further comprising adjusting a charge-rate of the battery in response to the charge level of the battery.

30. The method of claim 27, further comprising adjusting a charge-rate of the battery in response to the temperature of the battery.

31. A batter charging device, comprising:

a housing having an enclosed chute running through a central axis of the housing, the chute configured to permit batteries to pass through the housing, wherein a first end of the housing comprises an insertion slot and a second end of the housing comprises a dispensing slot;
