Abstract

A battery charger may accommodate simultaneous charging of one or more batteries. The battery charger may also accommodate high power charging of a single battery. Li-type and/or Ni-type Batteries equipped with RFID technology may communicate with the battery charger equipped with similar technology to provide default charge settings in response to battery chemistry type, cell count, recommended charge rates, number of charges on the battery, among other information. The charge parameters may be user-adjustable in an ‘advanced mode’ of the battery charger. Several safety features may be included.

Claims

1. A battery charger configured to simultaneously connect to a first battery and a second battery, comprising:

a first power section generating a first charge rate according to either a first low current setting or a first high current setting for charging the first battery;

a second power section for generating a second charge rate for charging the second battery when the second power section is in an enabled state;

an output mode selector electrically coupled to each of the first and second power sections that is user actuated to select operation of the battery charger from at least a high output mode and a dual output mode;

wherein the first charge rate is generated according to the first high current setting and the second power section is disabled when the high output mode is selected by user actuation of the output mode selector; and

wherein the first charge rate is generated according to the first low current setting and the second power section is enabled when the dual output mode is selected by user actuation of the output mode selector.

2. The battery charger according to claim 1 wherein the first low current setting comprises two or more charge rates.

3. The battery charger according to claim 1 wherein the first high current setting comprises two or more charge rates.

4. The battery charger according to claim 1 wherein the first low current charge rate and the second charge rate are independent in the dual output mode.

5. A battery charger configured to simultaneously connect to a first battery and a second battery, comprising:

an output mode selector operable to select between a high output mode and a dual output mode;

a first power section for generating a first charge rate for charging the first battery;

a second power section for generating a second charge rate for charging the second battery;

wherein the first charge rate is generated and the second charge rate is not generated when the high output mode is selected by a user; and

wherein the first charge rate and the second charge rate are generated when the dual output mode is selected by the user.

6. The battery charger according to claim 5 wherein the first charge rate is selected from a first high current setting in the high output mode;

and

the first charge rate is selected from a first low current setting in the dual output mode.

7. The battery charger according to claim 6 wherein at least one of the first low current setting or the high current setting comprises two or more charge rates.

8. The battery charger according to claim 5 wherein the second power section is disabled in high output mode.

9. The battery charger according to claim 5 wherein in dual output mode:

the first charge rate and the second charge rate are independently determined; and

the first charge rate is selected from a first low current setting.

10. A battery charger configured to simultaneously connect to a first battery and a second battery, comprising:

an output mode selector operable to select between a high output mode and a dual output mode;

a first power section for generating a first charge rate from either a first high output set of charging rates or a first dual output set of charging rates for charging the first battery;

a second power section for generating a second charge rate from a second dual output set of charging rates for charging the second battery;

wherein the first charge rate is generated from the first high output set of charging rates and the second charge rate is not generated when the high output mode is selected by a user; and

wherein the first charge rate and the second charge rate are generated from the first dual output set of charging rates and the second dual output set of charging rates respectively when the dual output mode is selected by the user.

11. The battery charger according to claim 10, wherein at least one of the first power section or the second power section further comprises a charge rate input device.

12. The battery charger according to claim 11, wherein the charge rate input device is a user activated switch that cycles through the charging rates of the corresponding first power section or the second power section according to the selected dual output mode or high output mode.

13. The battery charger according to claim 10, wherein at least one of the first power section or the second power section further comprises a battery type input device.

14. The battery charger according to claim 13, wherein the battery type input device is a user activated switch selecting between at least a Lithium-polymer (LiPo) battery or a Nickel-metal hydride (NiMH) battery for the corresponding first power section or the second power section.

15. The battery charger according to claim 14, wherein selection of a battery type initially sets a default value for the charging rates of the corresponding first power section or the second power section according to the selected dual output mode or high output mode.

16. The battery charger according to claim 10, wherein at least one of the first power section or the second power section further comprises a charging mode input device.

17. The battery charger according to claim 16, wherein the charging mode input device is a user activated switch that cycles through two or more charge modes for the corresponding first power section or the second power section.

18. The battery charger according to claim 17, wherein the two or more charge modes are three charge modes and comprise a storage mode, a fast mode, and a balance mode.

19. The battery charger according to claim 10, wherein input charge parameters for at least one of the first power section or the second power section are set to default settings in response to a battery type received from a connected battery.

20. The battery charger according to claim 10, wherein input charge parameters for at least one of the first power section or the second power section are set to default settings in response to receipt of a balance port connector.
