Method for operating an electric drive train of a work machine, electric drive train for a work machine and work machine

摘要

The invention relates to a method for operating an electric drive train (11) of a work machine (10), the drive train (11) comprising at least one electric motor (21, 31), an electrical energy store (34), status sensors and surroundings sensors, with at least one Electric motor (21, 31) in a drive mode according to a control input, electrical power (50, 51) is taken from the energy store (34), with electrical power (50 , 51) is fed into the energy store (34), electrical power (50, 51) supplied to the energy store (34) being converted into heat above a maximum power consumption capacity (52) of the energy store (34) and with the status sensors (13) and the environment sensor system (12) anticipates the situation. The method according to the invention is characterized in that in the recuperation mode the control input is automatically influenced according to the situation detection, so that the electrical power (50, 51) generated by the at least one electric motor (21, 31) in the recuperation mode reaches the maximum power consumption capacity (52) of the energy store (34) does not exceed. The invention also relates to a corresponding electric drive train (11) and a corresponding work machine (10).
