The invention provides a boost charging device and method, electronic equipment and a vehicle, the boost charging device comprises a three-phase inverter, a three-phase motor, a first switch, a second switch and a third switch, at a neutral point of the three-phase motor, a first winding is disconnected through the third switch; the first winding and the third winding are connected through a second switch; one end of the first switch is used for being connected with a charging pile, and when the three-phase motor is used as a boost inductor, the first switch and the second switch are closed, and the third switch is disconnected, so that current output by the charging pile sequentially flows through the first switch, the first winding, the second switch, the third winding and the second winding; and the power battery is charged after being subjected to boost conversion by a second half-bridge connected with the second winding. According to the invention, boost charging can be carried out on the power battery, and the boost inductance can be improved, so that the influence on the charging pile is reduced, or the requirement on an interface filter circuit between the charging pile and the whole vehicle is reduced.
