CHARGE PUMP BATTERY CHARGING

摘要

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.

主权项

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.
