A battery self-heating apparatus, comprising a first energy processing apparatus (10), a second energy processing apparatus (20) and a controller, which are connected to each other, wherein the controller is configured to control the turning-on and turning-off of a first inverter (11) and a second inverter (21) in a first preset state, such that a first power battery (1) and a second power battery (2) are charged/discharged by means of the first energy processing apparatus (10) and the second energy processing apparatus (20), so as to realize the heating of the first power battery (1) and the second power battery (2). Further disclosed are a battery self-heating method and an electric transport means. The apparatus can take full advantage of the characteristics of some electric transport means having two electric motors and two electric controls; and by means of making the two electric motors communicate with each other via a neutral line, the self-heating efficiency and power of a power battery are greatly increased, and a relatively low cost is also ensured.
