An electrified powertrain system (3) for an electric vehicle comprises a travel unit (31) and a work unit (32). The running unit (31) comprises a first motor (311) and a power transmission mechanism (312), the working unit (32) comprises a second motor (321), a working driving system (322) and working equipment (323), the electrified power system (3) further comprises a power distribution device (33), the power distribution device (33) is connected with the two motors (311 and 321) and used for distributing/combining power output by the two motors (311 and 321), and in the running mode, the power transmission mechanism (312) transmits power to the working unit (32). The power distribution device (33) is in a first working state so that output power from the two motors (311, 321) is combined and output to the power transmission mechanism (312). In the operation mode, the power distribution device (33) is in a second operating state such that only the output power of the first electric motor (311) is supplied to the power transmission mechanism (312) and only the output power of the second electric motor (321) is supplied to the operation drive system (322). According to the electrified power system (3), the use efficiency of the motors (311 and 321) is effectively improved, the system structure is simplified, the system cost is reduced, and the installation space is saved.
一种用于电动车辆的电气化动力系统(3),包括行驶单元(31)和作业单元(32)。行驶单元(31)包括第一电动机(311)和动力传输机构(312),作业单元(32)包括第二电动机(321)、作业驱动系统(322)以及作业设备(323),该电气化动力系统(3)还包括功率分配装置(33),分别与两个电动机(311,321)相连接,用于对两电动机(311,321)输出的功率进行分配/组合,在行驶模式下,功率分配装置(33)处于第一工作状态以使来自两电动机(311,321)的输出功率被组合输出给动力传输机构(312)。在作业模式下,功率分配装置(33)处于第二工作状态以使仅第一电动机(311)的输出功率被提供给动力传输机构(312),以及仅第二电动机(321)的输出功率被提供给作业驱动系统(322)。该电气化动力系统(3)有效地提高了电动机(311,321)的使用效率,简化了系统结构,降低了系统成本并节省了安装空间。
