Motor controller and electric vehicle with same

Abstract

The invention discloses a motor controller and an electric vehicle with the same, and the motor controller comprises a shell, an IGBT power module, a direct current filtering module, an alternating current busbar and a direct current bus capacitor, and the IGBT power module is arranged in the shell; the direct current filtering module is arranged in the shell, is positioned at one end of the IGBT power module and is electrically connected with the IGBT power module; the alternating current busbar is arranged in the shell, is positioned at the other end of the IGBT power module and is electrically connected with the IGBT power module; and the direct current bus capacitor is arranged below the shell, is electrically connected with the IGBT power module, and is overlapped with the IGBT power module. Therefore, the arrangement positions of the shell, the IGBT power module, the direct-current filtering module, the alternating current busbar and the direct current bus capacitor are more reasonable, and the space occupation of the motor controller can be reduced, so that the arrangement and installation of the motor controller on a power assembly are more convenient; and the compact design of the motor controller is realized, and the use requirement of high power density is met.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a motor controller and an electric vehicle with the same. Background technique [0002] With the continuous development of new energy vehicles, especially electric vehicles, the trend of integration and high integration of future powertrain systems is already very obvious. Generally speaking, the integration of core components in the powertrain system can not only increase the power density of the system, reduce energy loss in various links, improve energy efficiency, but also reduce costs, reduce volume, and achieve lightweight. [0003] In related technologies, domestic and foreign new energy vehicle manufacturers and parts manufacturers have successively launched their own integrated powertrain platform products, mainly focusing on the three-in-one integrated solution of motor, reducer and motor controller. [0004] However, the arrangement of various electrical components i...
