Patent Images
1. A powertrain battery life predicting apparatus comprising:
- a data processing unit for obtaining and processing data on a vehicle in which a battery is installed as a power source of the vehicle, the data consisting of 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;
wherein the battery environment data includes a temperature, the vehicle characteristic data includes a vehicle weight, and the vehicle running data includes a vehicle running distance;
a storage for storing data concerning battery deterioration obtained in a vehicle running test;
a controller for estimating a degree of battery deterioration relative to durable years of the battery from the vehicle characteristic data and the histories of the data recorded based on the data concerning battery deterioration in the recording unit and calculating remaining life of the battery; and
a display for visually showing information on the remaining life of the battery.
