1. A method for operating a multiple charger system, comprising:
- in a multiple charger system having at least a first switch and a second switch for respectively controlling the flow of current to a first battery and a second battery, charging the first battery by maintaining the first switch in a saturated state; and
charging the second battery by maintaining the second switch in a saturated state, wherein the first switch and the second switch are simultaneously maintained in the saturated state at least until the first battery reaches a predetermined charging threshold.

Abstract
The invention concerns a method (300) and system (100) for operating a multiple charger. The method can include—in a multiple charger (110) having at least a first switch (134) and a second switch (122) for respectively controlling the flow of current to a first battery (116) and a second battery (118)—charging (312) the first battery by maintaining the first switch in a saturated state and charging (314) the second battery by maintaining the second switch in a saturated state. The first switch and the second switch can be simultaneously maintained (314) in the saturated state at least until the first battery reaches a predetermined charging threshold (412, 414).

9. A system for operating a multiple charger, comprising:
-
a first switch, wherein the first switch controls the flow of current to a first battery;
a second switch, wherein the second switch controls the flow of current to a second battery; and
a processing unit coupled to the first switch and the second switch, wherein the processing unit is programmed to;
charge the first battery by maintaining the first switch in a saturated state;
charge the second battery by maintaining the second switch in a saturated state; and
maintain the first switch and the second switch in the saturated state simultaneously at least until the processing unit detects that the first battery has reached a predetermined charging threshold. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A charger for charging multiple batteries, comprising:
-
a first switch, wherein the first switch controls the flow of current from a power supply to a first battery; and
a processor coupled to the first switch, wherein the processor is programmed to;
charge the first battery by maintaining the first switch in a saturated state at the same time that a second switch is maintained in a saturated state to permit current to flow to a second battery, wherein the processor maintains the first switch in the saturated state while the second switch is in the saturated state at least until the processor detects that one of at least the first battery and the second battery has reached a predetermined charging threshold. - View Dependent Claims (18, 19, 20)
