Title:
CHARGING CURRENT CONTROLLER AND CHARGING CURRENT CONTROLLING METHOD
Document Type and Number:
Japanese Patent JP2016131452
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress voltage increase of a battery after transition from constant current charge control to constant voltage charge control.SOLUTION: The charging current controller includes: a voltage detection part 12, for detecting a voltage of a battery 11; and a control part 15, transiting from constant current charge control to constant voltage charge control when a voltage V, detected with the voltage detection part 12 reaches a target voltage. The control part 15, when a charging current is being raised during the constant current charge control and the voltage V, detected with the voltage detection part, reaches a correction target voltage obtained by subtracting a predicted polarization voltage from the target voltage, increase in the charging current is stopped.SELECTED DRAWING: Figure 1
