According to the multi-motor matching control system and method for the pure electric tractor, a high-voltage all-in-one control assembly is electrically connected with a power battery through a high-voltage line loop, and the high-voltage all-in-one control assembly communicates with a walking motor controller, a PTO motor controller and an oil pump motor; the walking motor controller and the PTO motor controller are respectively communicated with the walking motor and the PTO motor through high-voltage lines, the walking motor is in transmission connection with the walking system, the PTO motor is in transmission connection with the PTO system, and the oil pump motor is in transmission connection with the duplex oil pump. The whole machine control module is in communication with the high-voltage all-in-one control assembly, the power battery, the walking motor controller and the PTO motor controller. By means of the multi-motor mechanical decoupling scheme, mechanical transmission parts are reduced, the whole machine efficiency is higher, in addition, the oil pump motor, the walking motor and the PTO motor can be independently closed, and the better energy-saving effect can be achieved.

    本发明提供了一种纯电动拖拉机多电机匹配控制系统及方法,高压多合一控制总成通过高压线回路与动力电池电性连接,高压多合一控制总成分别与行走电机控制器、PTO电机控制器和油泵电机建立通信,行走电机控制器和PTO电机控制器分别通过高压线路与行走电机和PTO电机建立通信,行走电机与行走系统传动连接,PTO电机与PTO系统传动连接,油泵电机与双联油泵传动连接,还包括整机控制模块,整机控制模块分别与高压多合一控制总成、动力电池、行走电机控制器和PTO电机控制器建立通信;通过多电机机械解耦方案减少了机械传动部件,使整机效率更高,另外,油泵电机、行走电机和PTO电机可单独关闭,能够起到起到更好的节能效果。
