Abstract
Official abstract text for this publication.
A hybrid construction machine includes a distribution ratio setting unit that reduces an output distribution ratio of a motor generator by controlling an output control mechanism for controlling the output distribution ratio of the motor generator relative to an engine and increases an output distribution ratio of the engine by an amount corresponding to a reduction in the output distribution ratio of the motor generator when a temperature of a battery is lower than a threshold value in a low-temperature region or higher than a threshold value in a high-temperature region, and a regeneration amount control unit that reduces a hydraulic regeneration amount for the hydraulic motor by controlling an input control mechanism for controlling the hydraulic regeneration amount for the hydraulic motor when the temperature of the battery is lower than the threshold value in the low-temperature region or higher than the threshold value in the high-temperature region.
First claim
Opening claim text (preview).
The invention claimed is: 1. A hybrid construction machine, comprising: a main pump; an engine for driving the main pump; an assist pump connected to a discharge side of the main pump via a joint passage; a hydraulic motor rotated by return oil from an actuator; a motor generator linked to the assist pump and the hydraulic motor; an output control mechanism for controlling an output distribution ratio of the motor generator relative to the engine; an input control mech…
