Abstract:
When a hybrid-type construction machine including an electric power accumulator is started under a low-temperature environment, at first an ignition key of an engine is turned on to drive the engine. If the temperature of the electric power accumulator is lower than a predetermined temperature, the electric power accumulator is heated by driving the engine. Further, if the temperature of the electric power accumulator is lower than the predetermined temperature, the engine is driven to carry out a warm-up operation and a motor generator is driven to charging and discharge the electric power accumulator to thereby heat the electric power accumulator.
