Abstract

There comprises a battery body (9) arranged at the rear of an upper rotating body; an electric motor (17) arranged forwardly of and in the vicinity of the battery body; a hydraulic pump (18) connected to the electric motor; a working oil tank (20) arranged in the vicinity of the hydraulic pump; and a directional control valve for an actuator arranged in the vicinity of the hydraulic pump. Thereby, a power energy of a battery-driven construction machine can be utilized efficiently.
