A hybrid construction machine according to the present invention is constructed to drive electric motors (6, 7, 13, 15, 23, 25) by means of power of a power generator (11) to be driven by an engine (10), power of an auxiliary battery (42) and power of a main battery (12) charged with power of the po
A hybrid construction machine according to the present invention is constructed to drive electric motors (6, 7, 13, 15, 23, 25) by means of power of a power generator (11) to be driven by an engine (10), power of an auxiliary battery (42) and power of a main battery (12) charged with power of the power generator (11). The hybrid construction machine has a switch (43) for switching to drive the electric motors (6, 7, 13, 15, 23, 25) by means of power of at least one of the power generator (11) and the main battery (12) when operating normally and to drive the electric motors (6, 7, 13, 15, 23, 25) by means of power of the auxiliary battery (42) when operating emergency such that the electric motors (6, 7, 13, 15, 23, 25) can not be driven by means of the normal power.

What is claimed is: 1. A control apparatus of a hybrid construction machine for executing works by charging a main battery with power of a power generator to be driven by an engine and driving electric motors by means of power discharged from at least the main battery, comprising: a generator output control body for varying power output from the power generator in accordance with content of work performed by the hybrid construction machine. 2. The control apparatus of a hybrid construction machine according to claim 1, further comprising: a manipulating lever to be manipulated by an operator; and a work determination body for determining the content of the work on the basis of a manipulating signal from the manipulating lever and outputting the content of the work to the generator output control body. 3. The control apparatus of a hybrid construction machine according to claim 1, further comprising: a work mode switch with which the content of work can be selected by an operator; and a switch detection body for detecting the content of the work selected with the work mode switch and outputting the content of the work to the generator output control body. 4. A control apparatus of a hybrid construction machine for executing work by charging a main battery with power of a power generator to be driven by an engine and driving electric motors by means of power of at least one of the power generator and the main battery, comprising: a work speed regulation body for regulating work speed in accordance with content of the work when power of the power generator is a predetermined value or less. 5. The control apparatus of a hybrid construction machine according to claim 4, further comprising a manipulating lever to be manipulated by an operator; and a work determination body for determining the content of work on the basis of manipulating signal from the manipulating lever and outputting the content of the work to the work speed regulation body. 6. The control apparatus of a hybrid construction machine according to claim 4, further comprising: a work mode switch with which the content of work can be selected by an operator, and a switch detection body for detecting the content of the work selected with the work mode switch and outputting the content of the work to the work speed regulation body. 7. The control apparatus of a hybrid construction machine according to claim 1, wherein the hybrid construction machine is a hybrid excavator. 8. The control apparatus of a hybrid construction machine according to 4, wherein the construction machine is a hybrid excavator.
