An electric excavator according to the present invention comprises a lower traveling body and an upper rotating body rotatably coupled to the lower traveling body. The electric excavator is characterized by comprising: a first battery disposed on the lower traveling body; a second battery disposed on the upper rotating body; a travel motor, disposed on the lower traveling body, for moving the lower traveling body; a rotation motor, disposed on the upper rotating body, for rotating the upper rotating body; and a work motor, disposed on the upper rotating body, for operating a front work device that includes a boom and an arm. Power is supplied from the first battery and the second battery to the travel motor, the rotation motor, and the work motor, and the first battery and the second battery are connected in parallel.

    Une excavatrice électrique selon la présente invention comprend un corps mobile inférieur et un corps rotatif supérieur accouplé rotatif au corps mobile inférieur. L'excavatrice électrique est caractérisée en ce qu'elle comprend : une première batterie disposée sur le corps mobile inférieur ; une seconde batterie disposée sur le corps rotatif supérieur ; un moteur de déplacement, disposé sur le corps mobile inférieur, permettant de déplacer le corps mobile inférieur ; un moteur de rotation, disposé sur le corps rotatif supérieur, permettant de faire tourner le corps rotatif supérieur ; et un moteur de travail, disposé sur le corps rotatif supérieur, permettant d'actionner un dispositif de travail avant qui comprend une flèche et un bras. De l'énergie est fournie par la première batterie et la seconde batterie au moteur de déplacement, au moteur de rotation et au moteur de travail, et la première batterie et la seconde batterie sont connectées en parallèle.
