摘要

A hybrid storage battery (10) comprising a plurality of combined type batteries connected in series to each other and comprising, each, an organic solution based battery using an organic solution as an electrolyte that is connected in parallel to a battery based on an aqueous solution that uses aqueous electrolyte as an electrolyte, in which: the battery based on organic solution and the battery based on aqueous solution have average discharge voltages approximate each other in such a way that, when the hybrid storage battery ( 10) It is connected to a load, both batteries can drive the charge when discharged and are designed so that an abnormal battery overload voltage based on organic solution is higher than a final battery charge voltage based on aqueous solution and a final battery charge voltage based on organic solution is lower than the final charge voltage of the battery based on aqueous solution; the organic solution based battery becomes overcharged if it is charged beyond its final charge voltage and goes into an abnormality if it is charged beyond its abnormal overload voltage, and the aqueous solution based battery becomes overloaded if it is charged beyond its final charge voltage; and when each of the plurality of combined type batteries is fed with enough overload energy to make the organic solution based battery become overloaded, the aqueous solution based battery is configured to carry out a decomposition reaction of the aqueous electrolyte to absorb the overload energy so that a combined type battery charge voltage is suppressed to the final battery charge voltage based on aqueous solution, thereby preventing the organic solution based battery from reaching its abnormal overload voltage.
