Patent

CA 2223841

The present invention provides an estimate of the amount of time left on the battery by monitoring not only the voltage available from the battery, but also the amount of current flowing from the battery. It has been found that periodic sampling of the battery voltage and current drain enables accurate battery monitoring. The sampling technique alternates between sampling battery voltage and sampling current drain. An electric circuit is provided which enables the cost-effective sampling to occur. A method is then applied to the sampling signals by a microprocessor which determines the amount of time left under battery power. In a preferred embodiment, a graphic representation is provided of the amount of battery time left.

L'invention concerne un procédé qui permet d'évaluer l'autonomie restante d'une batterie en surveillant non seulement la tension disponible, mais aussi la quantité de courant qui en sort. Il a été découvert que l'échantillonnage périodique de la tension et du courant débité permet la surveillance précise de la batterie. La technique d'échantillonnage alterne entre l'échantillonnage de la tension de la batterie et l'échantillonnage du courant débité. Un circuit électrique permet un échantillonnage efficace en termes de coût. Une méthode est appliquée aux signaux d'échantillonnage par un microprocesseur, qui détermine l'autonomie d'alimentation de la batterie. Un mode de réalisation préféré comporte une représentation graphique de ladite autonomie.
