Quick charging apparatus
First Claim
1. A quick charging apparatus comprising means for feeding power from a apower source to a substantially dead secondary battery, a charge controlling means associated with said power feeding means and including means for adjusting fed power energy, means associated with said charge controlling means for feeding to said secondary battery a first average charging current of a relatively high level in a relatively short time so as to charge the battery with a required amount of energy for performing a single operation of an electric appliance to which said apparatus is applied, and means associated with the charge controlling emans for feeding to the battery a second average charging current of a relatively low level in a relatively long time so as to charge the battery to a level at least 80% of a fully chargeable amount of energy;
- said means for feeding said first average charging current including a first sensor for detecting said required amount of energy for said single operation in said secondary battery, and said means for feeding said second average charging current including a second sensor for detecting the amount of charge in the secondary battery.

Abstract
A quick charging apparatus capable of performing, in addition to normal charging operation for a secondary battery, a quick charging in the battery only a relatively small amount of energy required for performing desired N operations of an electric appliance to which the apparatus is applied, in a very short time. The apparatus comprises means for feeding a first average charging current of a relatively high level in a relatively short time, and means for feeding a second average charging current of a relatively low level in a relatively long time, said relatively small amount of energy being quickly charged with said first high average charging current.
