CONSTRUCTION MACHINE AND BATTERY PACK THEREOF

摘要

A construction machine is provided with management units (11, 12) configured to control the construction machine based on a plurality of limited power modes prescribed to control the output of a battery pack (18), and calculate an amount of electric power stored in the battery pack in each of the limited power modes based on specification information about the battery pack, on the state of charge of the battery pack, and on limited power and an operating voltage prescribed for each of the limited power modes; and a display device (14) configured to display the amount of electric power in each of the limited power modes based on the amount of electric power calculated by the management units. This allows the amount of electric power in the unselected limited power modes to be displayed and facilitates battery replacement work.

主权项

1. A construction machine for converting electric power stored in a battery into motive power, said construction machine comprising:
a battery control section configured to monitor charging and discharging of said battery, store specification information about said battery, and calculate a state of energy of said battery; a main control section configured to control said construction machine based on a plurality of limited power modes prescribed to control the output of said battery, and calculate an amount of electric power stored in said battery in each of said limited power modes based on limited power and operating voltage prescribed for each of said limited power modes as well as on said specification information and said state of energy input from said battery control section; and a display device configured to display the amount of electric power in each of said limited power modes based on said amount of electric power calculated by said main control section.
