The invention relates to the field of new energy automobiles, in particular to a charging topology for an electric automobile and a control method of the charging topology. The circuit comprises six power electronic switches and three motor resistors, wherein the six power electronic switches adopt separate devices or a first power electronic switch S1 and a second power electronic switch S2 adopt half-bridge modules, and a third power electronic switch S3, a fourth power electronic switch S4, a fifth power electronic switch S5 and a sixth power electronic switch S6 adopt H-bridge modules; after the first motor inductor La, the second motor inductor Lb and the third motor inductor Lc are connected in parallel, one end is connected with midpoints of the six power electronic switches to form a three-phase full-bridge converter, and a switch is additionally arranged in the middle of a neutral line leading-out end of the other end to form a combined topology. Charging is realized by using the motor controller, the motor winding and the single-phase lighting power, so that the power of the charging power supply is improved, and the charging time is shortened. In this way, a user can complete charging in a shorter time, and the convenience and practicability of the new energy automobile are greatly improved.
