Abstract
A hybrid construction machine includes a hydraulic apparatus having a pump; a regeneration apparatus configured to generate power using energy discharged from the hydraulic apparatus; a nonvolatile memory configured to store condition information indicating whether a condition of at least one of the hydraulic apparatus and the regeneration apparatus is normal or abnormal; a detection unit that detects the condition; a condition determination unit that generates condition information indicating whether the detected condition is normal or abnormal; an information comparison unit that compares the condition information generated by the condition determination unit with the condition information stored in the nonvolatile memory to determine whether or not content thereof is identical; and an updating unit that writes the condition information generated by the condition determination unit to the nonvolatile memory when a comparison result from the information comparison unit indicates that the content is different.
