摘要： A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a hydraulic actuator that drives driven parts including the lower traveling body and the upper turning body, a main pump that supplies hydraulic oil to the hydraulic actuators, a pump motor that drives the main pump, and a power storage device that supplies electric power to the pump motor. When the charging cable is connected to the charging port during the operation of the shovel, the shovel causes the hydraulic actuators to shift to the inoperable state. When the charging cable is connected to the charging port, the shovel does not start the pump motor even if an input for starting the pump motor is received from a user.

摘要： An excavator includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, actuators configured to drive driven portions including the lower traveling body and the upper turning body, a power storage mounted on the upper turning body and used as an energy source for driving the actuators, a cooling circuit configured to cool the power storage, and a fan mounted on the upper turning body and configured to blow air to a radiator and a condenser for cooling the radiator and the condenser. Further, the power storage is arranged such that the power storage is apart from a path in which air outside the upper turning body, by an operation of the fan, is introduced into inside the upper turning body, passes across the heat exchanging device, and is discharged to the outside of the upper turning body.
