Title:
BATTERY CHARGING EQUIPMENT
Document Type and Number:
Japanese Patent JPH08214463
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To obtain a battery charger for charging a plurality of batteries of electronic device by detecting the current state of battery and charging the batteries by enabling or disabling the elements in a charge switching circuit selectively, based on the state of battery thus detected. SOLUTION: A battery charger 100 is connected with a power supply 20 via an input cable 90 and is provided with charge switching circuit elements for feeding charges to a battery 110 under the control of a controller. The controller is provided with a state detection logic circuit and a charging logic circuit, wherein the state detection logic circuit detects the current state of the battery 110 whereas the charging logic circuit enables or disables the charge switching circuit elements selectively, based on the detection results of the state detection logic circuit thus charging the battery 110. With such arrangement, a plurality of batteries 210 in an electronic apparatus 50 can be charged.
