Abstract

A hybrid hydraulic excavator includes: an engine; a generator motor; an electric storage device; a commanding system being configured to command at least activation of a service mode for maintenance and execution of a charge-release process for the electric storage device; a display being configured to provide at least information on the charge-release process for the electric storage device; and a display controller being configured to control displaying of the display. The display controller commands the display to display charge-release-failure information when the charge-release process is ongoing at the elapse of a predetermined duration of time since the activation of the service mode was commanded.
