Abstract:
A shovel includes an electrically driven part subjected to temperature control during operation, a battery that supplies electric power to a constant electrical load that constantly operates apart from the electrically driven part, a first switch, and a second switch. The first switch opens or closes a power supply line between a temperature controller that controls the temperature of the electrically driven part and a photovoltaic power generator based on the temperature detection value of a temperature detector that detects the temperature of the electrically driven part. The second switch opens or closes a power supply line between the temperature controller and the battery based on the temperature detection value of the temperature detector.
