Abstract

A hybrid vehicle battery information display device (1) includes: battery service life display means (2) for estimating the battery degradation degree based on the service life of a battery (16) from the vehicle travel data according to the battery degradation data measured by a vehicle travel test (19) and displaying the information on the battery service life; travel fuel consumption display means (3) for evaluating lowering degree of the actual travel fuel consumption data based on the battery degradation for each operation pattern according to the test travel fuel consumption data set for each operation pattern from the vehicle travel test (19) and displaying information on the travel fuel consumption; and display control means (4) for controlling and displaying information on the battery service life.

Description

technical field [0001] The invention relates to a battery information display device for a hybrid vehicle. More specifically, it relates to a device arranged on an instrument panel of a hybrid vehicle mounted with a battery as a power source to display information related to the service life of the battery. Background technique [0002] A hybrid vehicle is a vehicle provided with a hybrid system. Such a hybrid system is a system that uses two types of power sources such as a gasoline engine and an electric motor in combination. This hybrid system is characterized by selectively using the gasoline engine and the electric motor according to the driving conditions of the vehicle and using the strengths of each to compensate for the weaknesses of the other. [0003] In addition, a hybrid vehicle using a gasoline engine and an electric motor together as a power source can operate using an engine with a smaller engine displacement than an equivalent conventional vehicle (ICE) us...
