Abstract

The invention discloses a portable storage battery for electric vehicles and a using method thereof. The portable storage battery includes storage battery units that include a storage battery casing, a storage battery cell is arranged in the storage battery casing, a socket is arranged at the end of the storage battery casing, and the socket is provided with a power plug. According to the invention, voltage required to drive one vehicle is in a manner of decentralization decomposed layer by layer, which brings convenience to both dismounting and mounting of the storage battery. The storage battery units are put in storage battery boxes in electric vehicles and connected with each other in series for use; in a case of out of power, the storage battery units are pulled out and then put into a charging cabinet to be connected with the charging cabinet through the socket to be charged.
