Abstract

PROBLEM TO BE SOLVED: To provide a charger for reducing a power consumption on stanby for charging and suppressing a discharge current transiently flowing when a charged battery pack is installed. SOLUTION: A driving power supply circuit 100 for driving a control circuit system is formed as an alternative system separated from a charging power supply circuit 300 regardless of a driven state or a non-driven state state of the charging power supply circuit 300. A microcomputer 50 alternately and intermittently controls the charging power supply circuit 300 in the driven state or the non-driven state when the charged battery pack 2 is not installed in the charger 200, reduces a potential difference between output voltages from the installed battery pack 2 and the charging power supply circuit 300, and suppresses the transient discharge current from the charged battery pack 2 when the battery pack 2 is installed.
