Title:
CHARGING DEVICE AND CHARGING METHOD
Document Type and Number:
Japanese Patent JP2018011386
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve durability of a charger.SOLUTION: The disclosed technology is a charging device including: a main power supply device which has a first current control circuit for outputting a first charging current being a constant current supplied to a secondary battery and a first temperature monitoring circuit for measuring a first temperature; and a sub power supply device which is connected in parallel to the main power supply device and has a second current control circuit for outputting a second charging current being a constant current supplied to the secondary battery. The first current control circuit sets the first charging current so that the first temperature is higher than a first threshold temperature and lower than a second threshold temperature.SELECTED DRAWING: Figure 6
