A work machine includes an engine, a motor-generator, a battery, a power detector, a temperature detector, and circuitry. The engine is to move the work machine. The motor-generator is to move the work machine and to generate electric power. The battery is to store the electric power generated by the motor-generator. The power detector is to detect a charge level of the electric power stored in the battery. The temperature detector is to detect a temperature of the battery. The circuitry is configured to control the motor-generator in accordance with the charge level selectively to move the work machine or to generate electric power when the temperature of the battery detected by the temperature detector is within a temperature range.

Work machine and method for controlling work machine

A work machine includes a machine body, an engine, a rotary electrical device, and an electric power controller. The engine is provided on the machine body to move the machine body. The rotary electrical device is provided on the machine body to move the machine body. The electric power controller is disposed above the rotary electrical device in a height direction along a height of the work machine to control the rotary electrical device.

The rotary electrical device is provided on the machine body to move the machine body and to generate electric power. The battery is to be charged by the rotary electrical device and to discharge electric power to the rotary electrical device to move the machine body. The battery being is provided adjacent to the engine.

A backhoe having an engine hood defining a recess for receiving part of a bottom surface of a driver's seat, and an engine mounted in horizontal posture inside the engine hood. The engine hood includes, in plan view, a first hood space corresponding to the recess, a second hood space and a third hood space arranged laterally of the recess, and a fourth hood space disposed rearwardly of the recess. A cooling air intake is formed in one of the second and third hood spaces, and a cooling air outlet is formed in the other of the second and third hood spaces.
