A power supply system for an electric vehicle includes: a battery system including one battery pack or a plurality of battery packs connected in parallel which is/are controlled by a Battery Management System (BMS) to connected to and disconnect from a high-voltage DC bus of the electric vehicle, wherein the battery system powers the electric vehicle; a range extender (3) to generate a DC current so as to charge the battery system and/or power the electric vehicle; a controller (4) to control a power generating mode of the range extender (3), to control a connection status of each battery pack with the high-voltage DC bus of the electric vehicle, and/or to control a connection status of the range extender (3) with the high-voltage DC bus of the electric vehicle; and a plurality of switches arranged between each battery pack and the high-voltage DC bus of the electric vehicle, and/or between the range extender (3) and the high-voltage DC bus of the electric vehicle. A control method and an electric vehicle using the power supply system are also described. The parallel battery system is used together with the range extender to power the electric vehicle, featuring modularization, integration/easy maintenance, and high reliability.
