Battery life prediction device and battery life warning device for power train

摘要

A battery life predicting apparatus comprises a data processing unit for obtaining and processing data on a vehicle having a battery used as a power source of the vehicle, the data including battery environment data, power consumption data concerning electrical components, and vehicle running data, a recording unit for recording vehicle characteristic data and histories of the data obtained and processed, a storage for storing data concerning battery deterioration obtained in a vehicle running test, and a controller for estimating a degree of battery deterioration relative to durable years of the battery from the data recorded in the recording unit and calculating remaining life of the battery, and presents the remaining life of the battery to a driver in the display. Further, a battery life warning apparatus estimates a timing of replacing the battery and presents a level of warning to the driver.
