The invention provides a pure electric tractor PT0 control system and method.The pure electric tractor PT0 control system comprises a power battery, the power battery supplies power to a PTO control unit and a walking unit through a high-voltage power distribution unit, the PTO control unit is electrically connected with a PTO motor, the PTO motor is in transmission connection with a PTO speed reduction device, and the pure electric tractor PT0 control system further comprises a whole vehicle control module; the whole vehicle control module establishes communication with the power battery, the PTO control unit and the man-machine interaction module. The system is mechanically decoupled from the walking unit and is not influenced by the walking unit; after mechanical decoupling, the wide speed regulation of the motor is utilized, the requirements of different rotating speeds can be met, the structure of a PTO mechanical gear shifting part is simplified, and the system efficiency is improved; and the required rotating speed can be calibrated according to different working condition requirements through the man-machine interaction module, the PTO transmission device part does not need to be redesigned and produced, and the platform applicability is high.

    本发明提供了一种纯电动拖拉机PT0控制系统及方法,系统包括动力电池,所述动力电池通过高压配电单元为PTO控制单元和行走单元供电,所述PTO控制单元与PTO电机电性连接,所述PTO电机与PTO减速装置传动连接,还包括整车控制模块,所述整车控制模块分别与所述动力电池、所述PTO控制单元和人机交互模块建立通信;系统与行走单元机械解耦,不受行走单元的影响;机械解耦后利用电机的宽调速,可实现不同转速的需求,简化PTO机械换挡部分结构,系统效率提升;通过人机交互模块可根据不同工况需求标定所需转速,不需要对PTO传动装置部分重新设计及生产,平台适用性强。
