VEHICLE POWER MANAGEMENT DEVICE

摘要

A vehicle power management device managing: a vehicle path information generation device generating a vehicle travel path: a drive assembly consuming power to drive the vehicle; a power generator; an electrical load device group; a high-voltage storage device storing power for driving the vehicle; a low-voltage storage device storing power for operating the electrical load device group; and a DC voltage conversion and output device converting voltage of power stored in the high-voltage storage device to generate DC voltage for operating the electrical load device group, and outputting the DC voltage, and controlling electric energy flow in the vehicle. The vehicle power management device controls output of the DC voltage conversion and output device so that a filling rate of the low-voltage storage device is between lower and upper limits of a range in which a charge and discharge speed is equal to or higher than a predetermined value.
