The present invention illustrates about the managing device for batteries which expands the durability of batteries and enhances the charging effect by maintaining the termination voltage of the rechargeable batteries used in all kinds of electrical devices and managing method for rechargeable battery thereof. The present invention provides a managing system for rechargeable batteries comprising a plurality of cells, a closed loop circuit method which connects the cells in parallel connection electrically, an electrical load means having regular voltage which is the sum of the maximum output voltage among the plurality of cells and being in parallel connection with the rechargeable cells which are connected in parallel with the closed loop circuit method, a switching means inserted between the plurality of cells and the electrical load means in order to cut off the current flowing in the electrical load means in case it reaches the discharge termination voltage of the plurality of rechargeable cells. |
