Estimating the charge of batteries.

摘要

An apparatus for continuously estimating the charge of electrochemical lead storage batteries includes data collection means for the measurement of battery voltage and current and the room temperature, a conditioning and conversion system for the signals from said data collection means, and a data processing system adapted to provide information and any control signals relative to all of battery operating parameters with reference to a predetermined dynamic model simulating the behavior of said battery. The dynamics of said model is corrected by error signals depending on the difference between the measured voltage and the voltage obtained from the model simulation in real time. <IMAGE>
