The present invention relates to an electric power construction machinery, which can effectively control or distribute power. The electric power construction machinery according to embodiments of the present invention includes a battery unit, a power distribution unit, a plurality of inverter units, a plurality of electric motors, and a vehicle control unit. The power distribution unit is electrically connected to the battery unit. The plurality of inverter units are electrically connected to the power distribution unit. The plurality of electric motors are electrically connected to the plurality of inverter units, respectively. The vehicle control unit is electrically connected to the plurality of inverter units, respectively, and delivers a control signal corresponding to an electric signal received from an operation unit to the inverter units. In addition, the vehicle control unit controls power required by the electric motors to be the same as or smaller than available power of the battery unit by controlling power supplied to the electric motors by the inverter units by using the control signal.

    본 발명의 실시예들에 따른 전기동력 건설기계는 배터리부, 전원분배부, 복수개의 인버터부, 복수개의 전동기 및 차량제어부를 포함한다. 전원분배부는 배터리부와 전기적으로 연결된다. 복수개의 인버터부는 전원분배부와 전기적으로 연결된다. 복수개의 전동기는 복수개의 인버터부와 각각 전기적으로 연결된다. 그리고 차량제어부는 복수개의 인버터부와 각각 전기적으로 연결되고, 조작부로부터 입력받은 전기적인 신호에 대응되는 제어신호를 인버터부에 전달한다. 또한, 차량제어부는 제어신호를 이용하여 인버터부가 전동기에 공급하는 전원을 제어함으로써, 전동기가 요구하는 요구 파워가 배터리부의 사용가능한 파워보다 같거나 또는 작게 제어한다.
