Abstract

A charger for charging a battery power source removably disposed on and connectable to the charger, the charger including a controller electrically connectable to a battery power source, at least one terminal connected to at least one of the controller and the battery power source, a power supply connectable to an outside power source, the power supply providing power to at least one of the controller and the battery power source, and a switch connected between the outside power supply and the power supply, the switch being activated when a battery pack is connected to the at least one terminal.

Claims

1. A charger for charging a battery power source removably disposed on and electrically connectable to the charger, the charger comprising:

a controller electrically connectable to the battery power source;

at least one terminal connected to at least one of the controller and the battery power source;

a power supply connectable to an outside power source, the power supply providing power to at least one of the controller and the battery power source; and

a switch connected between the outside power supply and the power supply, the switch being activated when a battery power source is connected to the at least one terminal.

2. The charger of claim 1, further comprising a fan connected to the power supply.

3. The charger of claim 2, wherein the fan is controlled by the controller.

4. The charger of claim 1, further comprising a current source connected to the power supply.

5. The charger of claim 4, wherein the current source is controlled by the controller.

6. A charger for charging a battery power source removably disposed on and electrically connectable to the charger, the charger comprising:

a controller electrically connectable to the battery power source;

at least one terminal connected to at least one of the controller and the battery power source;

a power supply connectable to an outside power source, the power supply providing power to at least one of the controller and the battery power source; and

a switch connected between the outside power supply and the power supply, the switch being activated when a battery power source is disposed on the charger.

7. The charger of claim 6, further comprising a fan connected to the power supply.

8. The charger of claim 7, wherein the fan is controlled by the controller.

9. The charger of claim 6, further comprising a current source connected to the power supply.

10. The charger of claim 9, wherein the current source is controlled by the controller.

11. A charger for charging a battery power source removably disposed on and electrically connectable to the charger, the charger comprising:

a controller electrically connectable to the battery power source;

at least one terminal connected to at least one of the controller and the battery power source;

a power supply connectable to an outside power source, the power supply providing power to at least one of the controller and the battery power source; and

a switch connected between the power supply and at least one of the controller and the battery power source, the switch being activated when a battery pack is connected to the at least one terminal.

12. The charger of claim 11, further comprising a fan connected to the power supply.

13. The charger of claim 12, wherein the fan is controlled by the controller.

14. The charger of claim 11, further comprising a current source connected to the power supply.

15. The charger of claim 14, wherein the current source is controlled by the controller.

16. A charger for charging a battery power source removably disposed on and electrically connectable to the charger, the charger comprising:

a controller electrically connectable to the battery power source;

at least one terminal connected to at least one of the controller and the battery power source;

a power supply connectable to an outside power source, the power supply providing power to the controller and the battery power source, wherein the power supply will not supply power to the controller unless the battery power source is connected to the power supply.

17. The charger of claim 16, further comprising a fan connected to the power supply.

18. The charger of claim 16, further comprising a current source connected to the power supply.

19. The charger of claim 18, wherein the power supply will not supply power to the current source unless the battery power source is connected to the power supply.
