A battery-operated work machine is provided which can perform a work while avoiding such a situation that the work machine cannot reach charging equipment. When the remaining capacity of a battery becomes lower than a first threshold value set in advance, a controller controls an inverter such that the revolution speed of an electric motor is kept at a target revolution speed and controls a first notification device to operate, and besides switches a traveling motor to a travel first speed side, in which the displacement volume is a large volume, irrespective of an input from a traveling mode instruction device, when the remaining capacity of the battery becomes lower than a first threshold value set in advance.

A method for damping juddering in the drive train of a vehicle having an electric motor as the drive motor, and a vehicle having a closed-loop control system to carry out the method. The method includes calculating an electric motor setpoint torque for actuating the electric motor from an electric motor request torque which corresponds to a current request for a torque, and calculating a correction torque as a function of the electric motor request torque and a correction factor which is determined from a rotational speed of the electric motor.

Electric vehicles such as scooters can have a first operating mode in which energy is supplied by a single electrical energy storage device and a second operating mode in which energy is supplied by multiple electrical energy storage devices. A circuit element can be included in the circuit connecting the electrical energy storage devices to a prime mover such as a traction motor. The circuit element has a first, electrically conductive, state that couples only the single electrical energy storage device to a traction motor and a second, electrically non-conductive, state that couples the multiple electrical energy storage devices to the prime mover. The transition of the circuit element from the first state to the second state can occur by irreversibly fracturing the circuit element upon installation of multiple electrical energy storage devices or by a controller transitioning the circuit element from the first state to the second state.
