Method for operating an electric drivetrain for a working machine, electric drivetrain for a working machine, and working machine

An electric drivetrain for a working machine, comprising:

• a work drive with an electric work motor;
• a travel drive with an electric travel motor and vehicle wheels;
• and
• a battery electrically connected to the electric work motor and the electric travel motor,
• wherein the vehicle wheels are rigidly drivably coupled or rigidly drivably couplable to the electric travel motor, so that in the event of a speed deceleration acting on the working machine from the outside that results in a braking force acting on the vehicle wheels the electric drivetrain is configured to detect in advance by a situation detection whether the braking force acting on the vehicle wheels due to the speed deceleration is lower than a driving force acting on the vehicle wheels due to a moment of inertia of the electric travel motor, and
• wherein the travel drive is configured to supply electrical power from the battery, the electrical power being supplied to the electric travel motor in a direction opposite to an operating direction of the electric travel motor to reduce the rotational speed when the situation detection detects that the braking force is lower than the driving force.
