Abstract

A battery-powered device can be simultaneously coupled to a non-battery power supply and to information signals from a battery. Power contacts on the device are coupled to the power supply, while one or more information contacts on the battery are coupled to corresponding contacts on the device.

Claims

1. A method comprising:

during one or more tests of a battery powered device;

providing more power to the battery-powered device from an external power supply than a battery of the device can provide, the external power supply providing power in place of the battery through a connector that physically fits between one or more power contacts on the battery-powered device and one or more power contacts on the battery when the battery is mechanically coupled to the battery-powered device such that one or more data signal contacts on the battery are brought into contact with one or more corresponding data signal contacts on the battery-powered device; and

providing one or more battery information data signals from the one or more data signal contacts on the battery to the one or more data signal contacts on the battery-powered device while power is simultaneously being provided through the connector from the external power supply to the battery-powered device.

2. The method of claim 1, wherein the connector that physically fits between the one or more power contacts on the battery-powered device and the one or more power contacts on the battery couples the one or more power contacts on the battery-powered device to the external power supply instead of to the one or more power contacts on the battery.

3. The method of claim 1, wherein the providing one or more battery information data signals comprises coupling at least two data signal contacts on the battery-powered device to at least two corresponding data signal contacts on the battery.

4. The method of claim 1, further comprising measuring power consumed by the battery-powered device.

5. An apparatus comprising:

a first connector configured such that, when a battery is mechanically received by a battery-powered device, the first connector physically fits between a first power contact on the battery-powered device and a first power contact on the battery while simultaneously allowing one or more data signal contacts on the battery to be in mechanical contact with one or more corresponding data signal contacts on the battery-powered device, the first connector configured to couple, during one or more tests of the battery-powered device, the first power contact on the battery-powered device to an external power supply in place of a coupling between the first power contact on the battery-powered device and the first power contact on the battery, the external power supply providing an amount of power during the one or more tests of the battery-powered device that is greater than the battery can provide.

6. The apparatus of claim 5, further comprising a switch configured to switchably couple the first power contact on the battery-powered device to the first power contact on the battery or to the power supply.

7. The apparatus of claim 6, the switch being configured to operate in response to one or more time-based signals.

8. The apparatus of claim 5, further comprising a second connector configured to couple the one or more data signal contacts on the battery-powered device to the corresponding data signal contacts on the battery.

9. The apparatus of claim 5, the first connector leaving the one or more data signal contacts on the battery exposed.

10. The apparatus of claim 5, further comprising a second connector configured such that, when the battery is mechanically received by the battery-powered device, the second connector physically fits between a second power contact on the battery-powered device and a second power contact on the battery of the battery-powered device while simultaneously allowing the one or more data signal contacts on the battery to be in mechanical contact with the one or more corresponding data signal contacts on the battery-powered device, the second connector configured to couple the second power contact on the battery-powered device and the second power contact on the battery to the external power supply.

11. The apparatus of claim 5, wherein at least one of the one or more data signal contacts on the battery is configured to provide battery capacity information data for the battery.

12. The apparatus of claim 5, wherein at least one of the one or more data signal contacts on the battery is configured to provide temperature information data for the battery.

13. The apparatus of claim 5, the first connector being composed at least in part of copper tape.

14. The apparatus of claim 5, the first connector being configured to provide an effective impedance substantially similar to an impedance of the first power contact on the battery.

15. A system for testing a plurality of battery-powered devices, the system comprising:

a chassis configurable to receive and test a plurality of battery-powered devices simultaneously; and

for each of the plurality of battery-powered devices, a connector configured such that when a battery is mechanically received by the battery-powered device, the connector physically fits between a power contact on the battery-powered device and a power contact on the battery while simultaneously allowing one or more data signal contacts on the battery to be in mechanical contact with one or more corresponding data signal contacts on the battery-powered device, the connector configured to couple the power contact on the battery-powered device to an external power supply in place of a coupling between the power contact on the battery-powered device and the power contact on the battery.

16. The system of claim 15, further comprising one or more circuits configured to control the transmission of data signals to one or more battery-powered devices coupled to the system.

17. The system of claim 15, wherein the chassis at least partially hides the plurality of battery-powered devices coupled to the system from view.

18. The system of claim 15, the system being configured to charge the battery of each of the battery-powered devices at one or more intervals.
