Abstract
Official abstract text for this publication.
The present charging rate of a battery is accurately calculated. The calculation mode of the present charging rate is switched to a current integration mode during operation of a generator motor while the mode is switched to a voltage reference mode at a predetermined switchover timing. In the current integration mode, charge current of the battery is integrated and added to the initial charging rate and an integrated discharge current value is subtracted from the initial charging rate of the battery to calculate the present charging rate. In the voltage reference mode, the present charging rate is calculated based on a predetermined map and detected voltage of the battery. After calculation of the present charging rate according to the voltage reference mode, the calculation mode is restored from the voltage reference mode to the current integration mode and the suspension of operating the generator motor is cancelled.
First claim
Opening claim text (preview).
What is claimed is: 1. A hybrid construction machine, comprising: a hydraulic actuator; a battery; an engine as a power source; a hydraulic pump which is connected to the engine as a hydraulic source for the hydraulic actuator; a generator motor which is connected to the engine, charges the battery by acting as a generator by power from the engine and assists the engine by acting as an electric motor by electric power from the battery; a voltage detector which detects te…
