The invention relates to a low-inductance high-efficiency thermal management integrated dual-motor drive bus capacitor and power module, which comprises a plurality of capacitor cores, the plurality of capacitor cores form core groups at equal intervals, the plurality of core groups are arranged in parallel, positive and negative electrodes of the adjacent core groups are alternately arranged, and power modules are arranged on the outer sides of the capacitor cores. A connecting mechanism is arranged between the capacitor core and the power module, the connecting mechanism is used for carrying out inductance elimination and cooling on the capacitor core and the power module, the connecting mechanism comprises a first busbar and a second busbar, the first busbar and the second busbar are fixedly arranged on the two opposite sides of the capacitor core, and the first busbar and the second busbar are both fixedly connected with the power module; and the heat dissipation mechanism is provided with an inlet and an outlet. The double-motor drive motor is low in stray inductance, capable of dissipating heat and conducting electricity, high in heat dissipation efficiency, uniform in heat dissipation, high in integration degree and suitable for a double-motor drive system.
