PURPOSE: A charging system including a battery lifetime diagnosis function is provided to diagnose a state of a battery by determining as a function of setting voltage and time by checking an internal state of the battery in a process of the battery charging without connecting a separate BMS(Battery Management System) to the battery and to simply recycle the battery in case that a battery lifetime is abnormal. CONSTITUTION: A charging system(100) having a battery lifetime diagnosis function includes a power supply unit(10) supplying current to charge a batter, a detection unit(20) detecting a charging current and a voltage of a battery and a diagnosis unit(30) diagnosing abnormality of a battery.
