Abstract

A battery pack including a housing, a plurality of battery cells located within the housing, and first, second, third, and fourth battery pack terminals. The housing includes a battery pack support portion configured to removably mechanically connect the battery pack to a first device and a second device. The first battery pack terminal is configured to electrically connect the battery pack to an interface of the first device. The second battery pack terminal is configured to electrically connect the battery pack to an interface of the second device. The third battery pack terminal is configured as a bypass terminal configured to bypass a current sensing circuit. The fourth battery pack terminal is configured to electrically connect the battery pack to the interface of the first device and the interface of the second device.

First claim

What is claimed is:

1. A battery pack comprising:
a housing including a battery pack support portion configured to removably mechanically connect the battery pack to a first device and a second device;
a plurality of battery cells located within the housing;
a first battery pack terminal configured to electrically connect the battery pack to an interface of the first device;
a second battery pack terminal configured to electrically connect the battery pack to an interface of the second device;
a third battery pack terminal configured as a bypass terminal configured to bypass a current sensing circuit; and
a fourth battery pack terminal configured to electrically connect the battery pack to the interface of the first device and the interface of the second device.

2. The battery pack of claim 1 , further comprising: a fifth battery pack terminal configured to electrically connect the battery pack to an interface of the first device, the fifth battery pack terminal having an electric polarity opposite than an electric polarity of the first battery pack terminal.

3. The battery pack of claim 1 , wherein the first device electrically connects to a first plurality of battery pack terminals and the second device electrically connects to a second plurality of battery pack terminals, wherein the second plurality of battery pack terminals includes fewer battery pack terminals than the first plurality of battery pack terminals.

4. The battery pack of claim 2 , wherein the first battery pack terminal and the fifth battery pack terminal are spaced apart by a first lateral separation.

5. The battery pack of claim 2 , wherein the fourth battery pack terminal and the fifth battery pack terminal are spaced apart by a second lateral separation.

6. The battery pack of claim 2 , wherein the first battery pack terminal and the fourth battery pack terminal are spaced apart by a third lateral separation.

7. The battery pack of claim 2 , wherein the second battery pack terminal and the fifth battery pack terminal are spaced apart by a fourth lateral separation.

8. The battery pack of claim 7 , wherein the third battery pack terminal and the fifth battery pack terminal are spaced apart by a fifth lateral separation the fifth lateral separation being approximately equal to the fourth lateral separation.

9. A battery pack comprising:
a housing including a battery pack support portion configured to removably mechanically connect the battery pack to a first device and a second device;
a plurality of battery cells located within the housing;
a first battery pack terminal configured to electrically connect the battery pack to an interface of the first device;
a second battery pack terminal configured to electrically connect the battery pack to an interface of the second device, the second battery pack terminal accessible through the central recess of the battery pack support portion;
a third battery pack terminal configured as a bypass terminal configured to bypass a current sensing circuit; and
a fourth battery pack terminal configured to electrically connect the battery pack to an interface of the first device, the fourth battery pack terminal having an electric polarity opposite than an electric polarity of the first battery pack terminal.

10. The battery pack of claim 9 , wherein the second battery pack terminal is configured as a charging terminal.

11. The battery pack of claim 9 , wherein the second battery pack terminal is configured as a low-power terminal.

12. The battery pack of claim 9 , wherein the second battery pack terminal is configured as a communication terminal.

13. The battery pack of claim 9 , wherein the second battery pack terminal is configured as a temperature terminal.

14. The battery pack of claim 11 , wherein the third battery pack terminal is further configured as a high-current terminal.

15. The battery pack of claim 10 , wherein the second battery pack terminal is configured to provide charging current to the battery pack when the first device is a battery pack charger.

16. The battery pack of claim 11 , wherein the second battery pack terminal is configured to receive power from the battery pack when the first device is configured as a low-power device.
