Apparatus and method of charging rechargeable battery
First Claim
1. A charging apparatus comprising:
- a voltage detector which detects a voltage value between terminals of a rechargeable battery;
a current generator which generates currents for charging the rechargeable battery and outputs the generated currents to the terminals of the rechargeable battery; and
a controller which controls the current generator based on the voltage value detected by the voltage detector,wherein the current generator outputsa first current for which a direction thereof between the terminals of the rechargeable battery is constant, in a charging period of the rechargeable battery, wherein the first current comprises direct current, anda second current for which a direction thereof between the terminals of the rechargeable battery is periodically reversed without a discharge pulse, in an intermittent period of the rechargeable battery.

Abstract
The apparatus of charging a rechargeable battery includes a voltage detector which detects a voltage value between terminals of a rechargeable battery, a current generator which generates current for charging the rechargeable battery and outputs the generated current to the terminals of the rechargeable battery, and a controller which controls the current generator based on the voltage value detected by the voltage detector. The current generator outputs a first current for which a direction thereof between the terminals of the rechargeable battery is constant, in a charging period of the rechargeable battery, wherein the first current comprises direct current, and a second current for which a direction thereof between the terminals of the rechargeable battery is periodically reversed, in an intermittent period of the rechargeable battery.

11. A charging method comprising:
-
outputting direct current having a constant direction between terminals of a rechargeable battery, to the terminals in a first charging period; stopping outputting the direct current, and outputting alternating current of which a direction thereof between the terminals of the rechargeable battery is periodically reversed without a discharge pulse, to the terminals in a first intermittent period; and stopping outputting the alternating current, and outputting the direct current having the constant direction between the terminals of the rechargeable battery, to the terminals in a second charging period. - View Dependent Claims (12, 13, 14, 15, 16)
