Electric vehicle integrated controller

Abstract

The present invention relates to an electric vehicle integrated controller, comprising any two or three of a driving circuit, an inverting circuit and a charging circuit. The driving circuit comprises a driving line for transmitting driving electric signals to a driving motor, and a first control switch provided on the driving line; the inverting circuit comprises an inverting line for outputting single-phase or three-phase three-wire or three-phase four-wire alternating current electric signals, an inverter provided on the inverting line, and a second control switch provided on the inverting line; the charging circuit comprises a charging line for charging a vehicle-mounted power battery, a rectifier provided on the charging line, and a third control switch provided on the charging line. The inverting circuit and the charging circuit are integrated and connected in series to the same line. According to the present invention, any two or three functions of driving, inverting and charging can be fulfilled, so that the purpose of improving the power utilization and / or expanding the charging mode of the battery can be achieved.

Description

technical field [0001] The invention relates to a controller used in an electric vehicle. Background technique [0002] At present, the controllers used in electric vehicles usually only have the function of driving the motor of the electric vehicle, that is, they can only provide the electric energy of the vehicle-mounted power battery to the drive motor as power, so that the power of the vehicle-mounted power battery cannot be fully utilized. Moreover, the charging method for the vehicle-mounted power battery is single, which is difficult to meet the demand. Contents of the invention [0003] The object of the present invention is to provide an electric vehicle integrated controller capable of realizing multiple functions, thereby improving the utilization rate of electric energy and / or expanding the charging mode of the battery. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] An electric vehicle integra...
