A battery self-heating control method and system, and an electric vehicle. The control method comprises: within a first preset time period in at least part of a control cycle in which drive control is performed on an electric motor, controlling a turned-on state of an upper bridge arm assembly and a lower bridge arm assembly to be a self-heating state, wherein in the self-heating state, there is an alternating current on a connecting line between the electric motor and a battery pack, such that a first battery group and/or a second battery group perform(s) charging and discharging alternately, thereby heating the battery pack.
