CONTROL SYSTEM AND CONTROL METHOD FOR HYBRID CONSTRUCTION MACHINE

WIPO Patent Application WO/2017/002509

A1

A control system (100) for a hybrid construction machine is provided with: fluid pressure pumps (71, 72); a regenerative motor (88) which is rotationally driven by a returning working fluid; a rotating electrical machine (91) which is rotationally driven by the regenerative motor (88); an electrical storage unit (26) which is charged by regenerated power; and a temperature detection unit (26a) for detecting the temperature of the electrical storage unit (26). In cases when the temperature of the electrical storage unit (26) is lower than a first set temperature, a control unit (90) implements regenerated power charging in an amount commensurate with an internal resistance corresponding to the temperature of the electrical storage unit (26), until a voltage higher than the charging end voltage when the temperature of the electrical storage unit (26) is equal to or more than the first set temperature is attained.
