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.

First claim

What is claimed is:

1. An electronic system comprising:
a charging device including an input port, a charge circuit, a storage at the charging device, and a connector device, the input port to receive a direct current (DC) voltage, the charge circuit to receive the DC voltage and to provide the DC voltage to the storage; and
an electronic device that includes a body, a battery, a first pad directly on the battery and a second pad directly on the 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 body of the electronic device, 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, and 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, and the first and second pads are to be exposed when the latch is open.

2. The electronic system of claim 1 , wherein the first pad directly contacts an anode of the battery, and the second pad directly contacts a cathode of the battery.

3. The electronic system of claim 1 , wherein the first pad directly contacts a cathode of the battery, and the second pad directly contacts an anode of the battery.

4. The electronic system of claim 3 , wherein the first pad is a metallic surface on the battery, and the second pad is a metallic surface on the battery.

5. The electronic system of claim 3 , wherein the first pad is one of nickel-plated steel, copper and gold-coated, and the second pad is one of nickel-plated steel, copper and gold-coated.

6. The electronic system of claim 1 , wherein the electronic device includes a protection device having a sliding surface to cover the first pad and the second pad.

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

8. The electronic system of claim 7 , 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.

9. The electronic system of claim 8 , wherein the battery is to be charged by the charging device without using the battery charger in the electronic device.

10. An electronic device comprising:
a body;
a battery to be provided in the body;
a first pad to directly contact the battery;
a second pad to directly contact the battery, and the first and second pads to directly 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 charging device, and the first and second pads are to be exposed when the latch is open.

11. The electronic device of claim 10 , wherein the first pad is a metallic surface on the battery, and the second pad is a metallic surface on the battery.

12. The electronic device of claim 10 , wherein the first pad is one of nickel-plated steel, copper and gold-coated, and the second pad is one of nickel-plated steel, copper and gold-coated.

13. The electronic device of claim 10 , comprising a protection device having a sliding surface to cover the first pad and the second pad.

14. A method of charging an electronic device, comprising:
receiving direct current (DC) voltage at a charging device;
charging the received DC voltage;
storing the charged DC voltage at a storage of the charging device based on the received DC voltage;
physically connecting the electronic device to a connecting device of the charging device; and
in response to physically connecting the electronic device to the connecting device of the charging device, providing DC voltage from the storage to a first pad and a second pad of the electronic device, the first pad directly contacts a battery of the electronic device, and the second pad directly contacts the battery of the electronic device,
wherein physically connecting the electronic device to the charging device includes:
directly contacting the first pad on the battery to a first terminal of the charging device, and
directly contacting the second pad on the battery to a second terminal of the charging device, wherein physically connecting the electronic device includes opening a latch of the electronic device based on contact with the connecting device.
