The invention relates to the technical field of electric automobiles, and discloses a power system of an electric automobile with double clutches and a control method thereof. The power system of the electric automobile with the double clutches comprises three motors, namely a first motor, a second motor and a third motor; two transmissions which are respectively a first transmission and a second transmission; two differential mechanisms which are respectively a first differential mechanism and a second differential mechanism; and two clutches which are the first clutch and the second clutch respectively, the first clutch is located between the first motor and the second differential mechanism, and the second clutch is located between the second motor or the third motor and the second differential mechanism. According to the power system of the electric automobile with the double clutches, the follow-up loss of the motor is reduced, so that the resistance is smaller and the power consumption is lower when the electric automobile is driven, and the endurance mileage of the electric automobile is prolonged.

    本发明涉及电动汽车技术领域,公开一种带双离合器的电动汽车的动力系统及其控制方法。其中带双离合器的电动汽车的动力系统包括:三个电机,分别为第一电机、第二电机及第三电机;两个变速器,分别为第一变速器和第二变速器;两个差速器,分别为第一差速器和第二差速器;两个离合器,两个离合器分别为第一离合器和第二离合器,第一离合器位于第一电机和第二差速器之间,第二离合器位于第二电机或者第三电机与第二差速器之间。本发明公开的带双离合器的电动汽车的动力系统,减小了电机的随转损失,使得电动汽车驱动时的阻力更小、耗电量更少,从而延长了电动汽车的续航里程。
