The invention provides a storage battery with the parallel charging function and belongs to the technical field of storage battery packs. The storage battery pack with the parallel charging function mainly solves the problem that in the prior art, batteries are overcharged, so that the service life of the batteries is shortened. The storage battery with the parallel charging function comprises a plurality of batteries and a rectifying device. The storage battery with the parallel charging function is characterized by further comprising parallel sockets, parallel plugs, a parallel switch set and series switches, wherein the negative electrode ends of the parallel sockets are connected with the negative electrode ends of the batteries, the positive electrodes of the parallel sockets are connected with the positive electrode ends of the batteries respectively, the parallel switch set comprises electrical control switches, the number of the electrical control switches corresponds to that of the batteries, each electrical control switch is connected between the positive electrode end of the corresponding parallel socket and the positive electrode end of the corresponding battery, the direct-current output end of the rectifying device is connected with the parallel switch set, the series switches are linkage multiway switches, each switch of the series switches is connected to a circuit which is formed by connecting two corresponding batteries in series, and each electrical control switch can be automatically switched off after the voltage of the corresponding battery reaches a certain value.
