Definitions

  • Still another technology described, for instance, in JP-A-2002-359935 relates to a hybrid work machine and appropriately changes a charge/discharge threshold value for an electrical storage section. More specifically, this technology selects a low charge/discharge threshold value for the electrical storage section when kinetic energy and potential energy are high and selects a high charge/discharge threshold value for the electrical storage section when the kinetic energy and potential energy are low.
  • the second inverter 34 converts DC power to AC power and converts AC power to DC power.
  • Measured applied load is input as the load.
  • the controller 17 is connected to the engine controller (not shown), a motor controller (not shown), and a battery controller (not shown) through communication means to determine the flow of energy and control the engine 10 , the motor-generator (M/G) 8 , the AC motor 35 , and the power supply system 1 in accordance with various parameters such as the amount of operation performed by the operator, the electrical storage status of the power supply system 1 , and the body information.
  • the work pattern of a construction machine such as the hydraulic excavator 2
  • the next operation can be easily estimated from the current operation.
  • the travel structure 401 for example, if the operator performs such an operation as to increase a vehicle speed, it is estimated that the next operation will be performed to decrease the vehicle speed.
  • the work section 400 if the operator performs such an operation as to raise the bucket 407 , it is estimated that the next operation will be performed to lower the bucket 407 .
  • the swing structure 402 turns to perform a power running operation, it is estimated that the next operation will be performed to decrease the speed of turning. In the present embodiment, it is particularly preferred that the next operation of the swing structure 402 be estimated.
  • the amount of electrical power to be regenerated can be determined by calculating the potential energy, for example, from the weight m [g] of earth placed in the bucket and from the height h [m] derived from the attitude information about the work section 400 .
  • the capacitor status detection section 41 detects a current capacitor voltage, that is, the current voltage v 0 of the capacitor.
  • the capacitor target voltage setup section 42 determines the capacitor target voltage V c * in accordance with the discharge command calculated as described above.
