The invention provides an electric drive assembly system, an electric drive assembly heat engine control method and related equipment. The method comprises the steps that the working state of an electric drive assembly is monitored; when the electric drive assembly is in a cold machine starting state, oil in the first oil storage cavity is controlled to reach a first oil level, and the first oil level is a preset value or a monitoring value when the liquid levels of the first oil storage cavity and the second oil storage cavity are the same; when the electric drive assembly is in the heat engine ending state, the oil liquid in the first oil storage cavity is controlled to flow into the second oil storage cavity, so that the oil liquid in the first oil storage cavity reaches a second oil liquid level; wherein the first oil liquid level is larger than the second oil liquid level. Namely, when the electric drive assembly heats the engine, the oil liquid level of the motor rotor and the differential gear during oil stirring is adjusted, the engine heating speed is increased, after engine heating is finished, the oil liquid level is lowered, the efficiency loss caused by oil stirring when the motor and the differential work at the high temperature is reduced, and the overall efficiency is improved.

    本说明书提供一种电驱动总成系统、电驱动总成热机控制方法及其相关设备,方法包括:监测电驱动总成的工作状态;当电驱动总成处于冷机启动状态时,控制第一储油腔内油液达到第一油液位,第一油液位为预设值或第一储油腔与第二储油腔的液位相同时的监测值;当电驱动总成处于热机结束状态时,控制第一储油腔内油液流通至第二储油腔内,以使第一储油腔内油液达到第二油液位;其中,第一油液位大于第二油液位。也即,在电驱动总成热机时,调节电机转子、差速器齿轮搅油时的油液位,提升热机速度,在热机结束后,降低油液位,减少高温下电机、差速器工作时搅油产生的效率损失,提升整机效率。
