Abstract

See full text

A first warming-up control unit calculates warming-up time charging power from a power storage SOC and power storage temperature and causes a generator motor to perform power generation operation thereby charging a power storage unit on the basis of the calculated warming-up time charging power. A second warming-up control unit applies, during the power generation operation, a hydraulic load to a hydraulic pump by a hydraulic load unit and performs horsepower control of the hydraulic pump using a value obtained by subtracting the warming-up time charging power from preset warming-up time pump horsepower.
