Abstract
An estimation method for residual discharging time of batteries includes the steps of: providing a set of battery-discharge-current intervals and a set of battery-discharge equations, setting the discharge time of each battery-discharge-current intervals at zero; detecting a discharge current, voltage and time of batteries; judging whether the discharge current exceeds all of the battery-discharge-current intervals; selecting one of the battery-discharge-current intervals and the associated battery-discharge equation according to the detected discharge current; calculating an estimation of residual discharging time; accumulating and recording the discharge time; judging whether the discharge voltage is lower than a predetermined value and calculating an estimation error of the residual discharging time; and adjusting parameters of the battery-discharge equation for reducing the estimation error of the residual discharging time if the estimation error is greater than a predetermined error value.
