APPARAUS FOR STORING AND SUPPLYING ELECTRIC ENERGY CAPABLE OF EXTENDING LIFE SPAN OF BATTERIES VIA DIAGNOSIS AND REVIVAL OF THE BATTERIES

摘要

PURPOSE: An apparatus for storing and supplying power is provided to extend a life span by evaluating the suitability of battery regeneration and generating a battery. CONSTITUTION: An electrode interface(42) is connected with electrode terminals of a battery selected through a battery connection interface. A pulse generating unit(43) generates a current pulse which is applied to a battery through an electrode interface. A measuring unit measures voltages between battery electrode terminals through the electrode interface. A diagnosis and regeneration control unit(41) controls the pulse generating unit to generate a predetermined size of current pulses to diagnose a battery state and regeneration suitability. The diagnosis and regeneration control unit determines the regeneration suitability of the battery based on the voltage change between the battery electrode terminals.
