First Claim
Patent Images
1. A system, comprising:
- a charge storage device that accumulates charge from a current below a first current level;
a discharge device that selectively discharges a discharge current from the charge storage device, wherein at least a portion of the discharge current is at a second current level greater than the first current level; and
a battery that receives the discharge current to facilitate recharging the battery.

Abstract
Charge pump battery charging is disclosed. Charge pump battery charging can include accumulating charge on a charge storage device. The accumulated charge can be selectively discharged to facilitate recharging a battery. The discharge current can generally be at a higher average current than the charging current. The selective discharge can be based on a determined a discharge time, a determined duty cycle, or monitoring of the accumulated charge on the charge storage device. Control values related to the selective discharge can be updated from remotely located devices. Charge pump battery charging can provide for high current pulsed charging of NiMH battery cells at a low input current.

11. A method, comprising:
-
accumulating charge on a charge storage device at a current below a first determined current level; and selectively activating a discharge device to facilitate conductively coupling the charge storage device to a battery for a discharge period to facilitate recharging the battery, wherein conductively coupling the charge storage device to the battery results in discharging the charge storage device at a current that is greater that the first determined current level for at least a portion of the discharge period. - View Dependent Claims (12, 13, 14)

17. A computer-readable storage medium having instructions stored thereon that, in response to execution, cause a device comprising a processor to perform operations, the operations comprising:
-
accumulating charge on a capacitor at an amperage below a first defined amperage current; and selectively activating a switch to facilitate conductively coupling the capacitor to a battery for a discharge period to facilitate recharging the battery, wherein, in response to the capacitor being conductively coupled to the battery, the capacitor discharges at another amperage that is greater than the first defined amperage for at least a portion of the discharge period. - View Dependent Claims (18, 19, 20)
