Abstract

An electronic system may include a charging device and an electronic device. The charging device may include an input port, a charge circuit, a storage, and a connector device. The charging device may receive a direct current (DC) voltage at the input port. The charge circuit may receive the DC voltage and provide a charged voltage to the storage. The electronic device may include a body, a battery, a first pad directly on the battery and a second pad directly on the battery. The battery may receive the DC charged voltage when the electronic device is coupled to the charging device.

Claims

1. An electronic system comprising:

a charging device including a charge circuit, a storage at the charging device, and a connector device, the charge circuit to receive a direct current (DC) voltage and to provide the DC voltage to the storage; and

an electronic device that includes a body and a battery, and the battery to receive the DC voltage from the storage of the charging device when the electronic device is physically coupled to the connector device of the charging device, wherein the battery is within the electronic device, wherein the electronic device includes a latch at the body, and wherein the latch is to open based on contact with the connector device of the charging device.

2. The electronic system of claim 1, wherein the electronic device includes a first pad on the battery, and a second pad on the battery.

3. The electronic system of claim 2, wherein the first pad directly contacts one of an anode or a cathode of the battery, and the second pad directly contacts another of the anode or the cathode of the battery.

4. The electronic system of claim 2, wherein the latch is to open to provide access to the first pad and the second pad.

5. The electronic system of claim 2, wherein the first pad is a metallic surface on the battery, and the second pad is a metallic surface on the battery.

6. The electronic system of claim 2, wherein the connector device includes a first terminal and a second terminal, the first pad to physically contact the first terminal when the electronic device is physically coupled to the connector device, and the second pad to physically contact the second terminal when the electronic device is physically coupled to the connector device.

7. The electronic system of claim 2, wherein the first pad is one of nickel-plated steel, copper or gold-coated, and the second pad is one of nickel-plated steel, copper or gold-coated.

8. The electronic system of claim 2, wherein the electronic device includes a protection device having a sliding surface to cover the first pad and the second pad.

9. The electronic system of claim 1, further comprising an alternate current (AC) adapter to receive an AC voltage from a first power source and to provide the DC voltage to the charging device.

10. The electronic system of claim 9, wherein the electronic device further includes a battery charger to receive power from a second power source, and the battery charger to provide power to the battery.

11. The electronic system of claim 9, wherein the battery is to be charged by the charging device without using the battery charger in the electronic device.

12. The electronic system of claim 2, wherein the latch, when closed, is to cover the first pad and the second pad.

13. An electronic device comprising:

a body, wherein a battery is to be provided in the body;

a first pad to be on the battery;

a second pad to be on the battery, and the first and second pads to receive direct current (DC) voltage from an external charging device when the electronic device is physically coupled to the external charging device; and

a latch at the body, wherein the latch is to open based on contact with a connector device of the external charging device, when the electronic device is to be attached to the charging device.

14. The electronic device of claim 13, wherein the latch, when closed, is to cover the first pad and the second pad.

15. The electronic device of claim 13, wherein the first pad is one of nickel-plated steel, copper or gold-coated, and the second pad is one of nickel-plated steel, copper or gold-coated.

16. The electronic device of claim 13, comprising a protection device including a sliding surface to cover the first pad and the second pad.

17. A method of charging an electronic device, comprising:

storing a direct current (DC) voltage at a storage of a charging device based on received DC voltage;

connecting the electronic device to a connecting device of the charging device; and

in response to connecting the electronic device to the connecting device of the charging device, providing the DC voltage from the storage to a battery of the electronic device,

wherein connecting the electronic device to the charging device includes;

contacting a first pad on the battery to the connecting device of the charging device, and

contacting a second pad on the battery to the connecting device of the charging device, wherein connecting the electronic device includes opening a latch of the electronic device.

18. The method of claim 17, wherein opening the latch is based on contact with the connector device.

19. The method of claim 18, further comprising charging the battery of the electronic device using a second power source.

20. The method of claim 19, wherein the battery is to be charged by the charging device without using a battery charger in the electronic device.
