  "textContent": "A method of charging a storage battery comprising executing an n(n≧2)-stage constant current charging process charging the battery with a constant current while monitoring a terminal voltage of the battery, the current decreasing stepwise n-1 times every time the terminal voltage coincides with a current switching voltage. The method further comprises measuring a depth of discharge of the battery immediately before charging and executing an additional charging process before the n-stage constant current charging process when the depth of discharge is deeper than a reference depth of discharge, the additional charging process charging the battery with an additional constant current larger than an initial current in the n-stage constant current charging process and switching the additional current to the initial current when the terminal voltage coincides with the current switching voltage, so as to attain a rapid charging of the battery at a low cost.",
