Dual battery charging device
First Claim
1. A dual mode battery charging device, comprising:
- a battery charging section having output connectable to apply potential differences across a plurality of electrically isolated batteries; and
a charging control section which changes a charging switching period of a charging signal in the battery charging section in accordance with the number of batteries being charged, and outputs a control signal to the battery charging section to place operation of said charging section in one of a standard charging mode and a quick charging mode.

Abstract
A dual mode battery charging device for charging a plurality of batteries includes a battery charging section for charging the batteries, and a charging control section for changing the switching period of a charging signal in the battery charging section in accordance with the number of batteries to be charged and outputs a control signal to the battery charging section which determines whether the charging section operates in a standard charging mode or a quick charging mode. In accordance with the number of batteries mounted, only one battery can be quickly charged or two batteries can be simultaneously charged at a normal speed. Therefore, the capacity of a battery and its available time increase.

9. A dual mode battery charging device for charging a pair of batteries, comprising:
-
a battery charging section having an output connectable to apply potential differences across a pair of electrically isolated batteries; a first receiving means for receiving and electrically connecting a first of the pair of batteries to be charged to said battery charging section; a second receiving means for receiving and electrically connecting a second of the pair of batteries to be charged to said battery charging section; and a charging control section for controlling a charging rate of said battery charging section such that said battery charging section operates in a quick charging mode when only one of said first and second receiving means has received a battery to be charged and operates in a standard charging mode when both said first and second battery receiving means have received batteries to be charged, the battery charging device charging the single battery in a quick charging mode faster than when it charges the pair of batteries in a standard charging mode. - View Dependent Claims (10, 11)

12. A computer system having a dual mode battery charging device for charging a pair of batteries, comprising:
-
an AC/DC converter for outputting a DC voltage; a battery charging section having an output connectable to apply potential differences across a pair of electrically isolated batteries, said battery charging section receiving said DC voltage output by said AC/DC converter; a first receiving means for receiving and electrically connecting a first of the pair of batteries to be charged to said battery charging section; a second receiving means for receiving and electrically connecting a second of the pair of batteries to be charged to said battery charging section; and a charging control section for controlling a charging rate of said battery charging section such that said battery charging section operates in a quick charging mode when only one of said first and second receiving means has received a battery to be charged and operates in a standard charging mode when both said first and second battery receiving means have received batteries to be charged, the battery charging device charging the single battery in a quick charging mode faster than when it charges the pair of batteries in a standard charging mode. - View Dependent Claims (13, 14)
