CONSTRUCTION MACHINERY AND BATTERY PACK THEREFOR

摘要

Construction machinery provided with: control units (11, 12) for controlling the construction machinery on the basis of multiple limited power modes prescribed for limiting the output of the battery pack (18), the control units calculating the amount of residual power in the electricity-storing pack for each of the multiple limited power modes on the basis of the specifications and state of charge of the electricity-storing pack as well as the power limit and operating voltage prescribed for each of the multiple limited power modes; and a display unit (14) for displaying the amount of residual power for each of the multiple limited power modes based on the amount of residual power calculated by said control units. The result is that the amount of residual power for the limited power modes that have not been selected can be displayed and battery-changing work is facilitated.
