【発明の名称】電池充電器および電池充電検出制御方法
Document Type and Number:
Japanese Patent JP3372901
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To inform an accurate level of a charging state to a user by judging the level of the charging state from a charging start state to a charging complete state with uniform distribution. SOLUTION: A battery charger 10 comprises a charging circuit 1 for charging a battery a resistor 6 for generating a voltage responsive to a charging current of the battery a battery voltage detector 4 for detecting a voltage at both terminals of a plurality of the battery voltages of the battery in a constant voltage charging control zone based on the voltage at both the terminals of the battery to generate data of the battery voltage a controller 2 for controlling the battery charge in the step of collecting charging current, ordinary charging current and battery voltage, and changing the mode to a constant the full charge, voltage charge at and for reading that the battery approaches the full charge and becomes the ordinary charging current ID4 or below by the resistor 6 to detect the completion of charging and a display unit 7 for displaying the charging state in the step up to the completion of charging of the battery.
