The embodiment of the invention provides a battery self-heating control method, a battery self-heating control system and an electric vehicle. The control method comprises the steps that in a first preset time period in at least part of a control period of driving control over the motor, the conduction state of the upper bridge arm assembly and the lower bridge arm assembly is controlled to be a self-heating state, in the self-heating state, a connecting line between the motor and the battery pack has alternating current, and in the self-heating state, the connecting line is connected with the battery pack; and alternately charging and discharging the first battery pack and/or the second battery pack so as to heat the battery pack.
本申请实施例提供了一种电池自加热控制方法、控制系统及电动交通工具。该控制方法包括:在对所述电机进行驱动控制的至少部分控制周期内的第一预设时间段内,控制所述上桥臂组件和下桥臂组件的导通状态为自加热状态,在所述自加热状态下,所述电机与所述电池包之间的连接线上具有交流电,使所述第一电池组和/或第二电池组交替充放电,从而加热所述电池包。
