Electric construction machinery according to embodiments of the present disclosure includes a battery unit, a power distribution unit, a plurality of inverter units, a plurality of 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 motors are electrically connected to the plurality of inverter units, respectively. In addition, the vehicle control unit is electrically connected to each of the plurality of inverter units and transmits, to the inverter units, a control signal corresponding to an electrical signal received from an operation unit. Moreover, the vehicle control unit detects usable power of the battery unit, and uses the control signal so as to control power supplied to the motors by the inverter units, and thus controls power required by the motors to be less than or equal to the usable power of the battery unit.
