CHARGING SYSTEM AND CHARGING METHOD FOR SECONDARY BATTERY

Abstract

A charging system for a secondary battery includes: a current sensor that measures a current flowing in the secondary battery; and a control apparatus that, during charging of the secondary battery, refers to a measurement value of the current sensor and performs charging control of the secondary battery. The current sensor includes a magnetic current sensor. The charging control includes setting of a chargeable current value that is allowed during the charging of the secondary battery. When a ripple is detected from the measurement value of the magnetic current sensor and a current value of the detected ripple is not less than a predetermined current value, the chargeable current value is set using the current value of the detected ripple.
