An electric construction machine that can travel from a work site to charging equipment and prevent the lowering of the work efficiency is provided. An electric hydraulic excavator includes a motor (28) that is driven by power of a battery device (19) and drives a hydraulic pump (29), a controller (37), and a display device (24). The controller (37) computes and stores the amount of consumed power of the motor (28) consumed during the period from the departure of the hydraulic excavator from the charging equipment to arrival at the work site, based on movement information of the hydraulic excavator acquired by a movement information acquiring device. The controller (37) subtracts the amount of consumed power from the amount of stored power of the battery device (19) to compute the amount of power consumable at the work site. The controller (37) computes the period of time for which operation is possible at the work site, based on the amount of power consumable at the work site, and causes the display device (24) to display the period of time for which operation is possible at the work site.
