The invention relates to the technical field of electric vehicles, in particular to a battery heating system and an electric vehicle. The battery heating system comprises a battery module, a heating module, a battery management module, a charge state power supply and a running state power supply. One end of the heating module is connected with one end of the battery module by a heating contactor, and the other end of the heating module is connected with the other end of the battery module by a cathode contactor; the heating module is further connected with the charge state power supply and the running state power supply; the battery module is connected with the running state power supply and the running state power supply; the battery management module is connected with the battery module. The battery heating system and the electric vehicle have the advantages that the battery heating system have simple circuits and few components, heating and heat-insulation effects can be effectively realized for batteries when the integral electric vehicle is charged and runs, accordingly, the batteries can always work at the optimal temperature points, the performance of the batteries can be optimized to the greatest extent, the service lives of the batteries can be prolonged, and the service performance of the integral electric vehicle can be improved.
