<P>PROBLEM TO BE SOLVED: To provide a warming-up method for a hybrid type construction machine capable of efficiently and quickly warming a battery without separately using a heating device. <P>SOLUTION: When temperature of a battery 19 is lower than predetermined temperature, an engine 11 is operated to perform warming-up operation. Concurrently, an assist motor 12 is actuated to charge/discharge the battery 19, so that the temperature of the battery 19 is raised using internal heating of the battery 19. <P>COPYRIGHT: (C)2013,JPO&INPIT |
