The composite invention discloses a storage battery with simultaneously rechargeable unit cells and a multipath parallel-connected charger, and aims to provide a more ideal storage battery and a corresponding charging method for electric automobiles. The storage battery with simultaneously rechargeable unit cells comprises a storage battery shell, a positive plate, a negative plate, a separation plate, a positive bus bar, a negative bus bar, a gap bridge, a tab, an upper cover, electrolyte, a power circuit, a positive and negative pulse charging circuit, a unit cell detection circuit, a central processing unit (CPU) main control circuit and a power control circuit; a pole at the upper end of the rechargeable gap bridge of the storage battery passes through a connecting hole on the upper cover of the storage battery and then is connected with a charging lead wire by a screw, so the unit cells of the storage battery can be charged; and the same number of relatively independent charging power supplies are made for the charger according to the number of the unit cells of the storage battery. By the storage battery with the simultaneously rechargeable unit cells, the charging speed is increased, and the charging time is shortened, so the voltage of the storage battery or the storage battery group is more balanced or more sufficient; and adverse influences that some unit cells are overcharged and heated and some unit cells are charged insufficiently when the unit cells of the storage battery are charged in the conventional serial charging mode are eliminated.
