Abstract

The embodiment of the application relates to a controller and an electric driving system, wherein the controller comprises a shell, a plurality of conductive pieces and a PCB, the conductive pieces are fixed in a coating manner by the shell, the conductive pieces are insulated from each other by the shell, one end of each conductive piece is exposed out of the shell to be electrically connected with external equipment, and the other end of each conductive piece is electrically connected to the PCB. Because the shell cladding is fixed electrically conductive piece, then electrically conductive piece and external equipment (such as power and motor) when locking, reduce electrically conductive piece because of locking moment of torsion pivoted risk by a wide margin, need not in addition lock electrically conductive piece pay on shell or other auxiliary equipment (such as radiator), convenient and fast.
