Abstract: In a method of efficiently managing and extending life of a battery bank, it is identified whether lifespan characteristic value of a battery bank unit reaches a predetermined threshold value of lifespan extension, by monitoring a lifespan characteristic value of an individual battery bank unit. While the other battery bank units normally supply power, a high-frequency electric pulse is applied to an identified battery bank unit through a DC/DC converter. Thus, materials preventing an electrochemical reaction accumulated on an electrode are removed.
