Abstract

Abstract In a power supply control apparatus capable of connecting an AC adapter (11), it is determined by a controller (16) whether or not the AC adapter (11) is connected. When a battery (13a; 13b) is set in the apparatus, it is determined whether the battery (13a; 13b) is in a low battery state. When the AC adapter (11) is connected and the set battery (13a; 13b) is in a low battery state, charge operation for the battery (13a; 13b) is started. During charging, a charged state is monitored on the basis of the current value detected by a current detector (14a; 14b) and a charge time measured by a timer (16a). When the charge amount exceeds a predetermined amount, or the charge time exceeds a predetermined charge time, the charge operation is completed and the battery (13a; 13b) is used as a power supply.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 133 words
A battery control apparatus characterized by comprising: at least one battery (13a; 13b) to be set; an AC adapter (11); checking means (15a, 16; 15b, 16) for checking whether or not the set battery is in a low battery state; charging means (12) for charging the set battery (13a; 13b) by the AC adapter (11) when the set battery (13a; 13b) is in the low battery state; obtaining means (16a) for obtaining a charge period of the set battery; detecting means (14a, 16; 14b, 16) for detecting a charge amount of the set battery (13a; 13b); and determining means (16) for determining whether or not a desired charge amount for the set battery (13a; 13b) is obtained in accordance with at least one of the detected charge amount and the obtained charge period.
Claim 2
Dependent Claim 31 words
The apparatus according to claim 1, characterized in that the set battery (13a; 13b) with the low battery state is charged until the detected charge amount exceeds the desired charge amount.
Claim 3
Dependent Claim 31 words
The apparatus according to claim 1, characterized in that the set battery (13a; 13b) with the low battery state is charged until the obtained charge period exceeds the desired charge period.
Claim 4
Dependent Claim 88 words
A battery control method characterized by comprising the steps of: checking whether or not at least one battery to be set is in a low battery state; charging the set battery when the set battery is in the low battery state; obtaining a charge period of the set battery; detecting a charge amount of the set battery; and determining whether or not a desired charge amount for the set battery is obtained in accordance with at least one of the detected charge amount and the obtained charge period.
Claim 5
Dependent Claim 29 words
The method according to claim 4, characterized in that the set battery with the low battery state is charged until the detected charge amount exceeds the desired charge amount.
Claim 6
Dependent Claim 29 words
The method according to claim 4, characterized in that the set battery with the low battery state is charged until the obtained charge period exceeds the desired charge period.
