A battery having a built-in controller is disclosed that extends the run time of the battery. The controller may extend the run time of the battery, for example, by converting the cell voltage to an output voltage that is greater than a cut off voltage of an electronic device, by converting the cell voltage to an output voltage that is less than the nominal voltage of the electrochemical cell of the battery, or by protecting the electrochemical cell from current peaks. The controller may also include a ground bias circuit that provides a virtual ground so that a converter may operate at lower cell voltages. The battery may be a single-yell battery, a universal single-cell battery, a multiple-cell battery or a multiple-cell hybrid battery.
On décrit une pile munie d'un contrôleur intégré pouvant prolonger la durée de vie de la pile. Ce contrôleur peut prolonger la durée de vie de la pile, par exemple, en transformant la tension d'élément en tension effective supérieure à une tension de blocage d'un dispositif électronique, en transformant la tension d'élément en tension effective inférieure à la tension nominale de la cellule électrochimique de la pile, ou en protégeant la cellule électrochimique des pointes de courant. Le contrôleur peut également inclure un circuit de polarisation mis à la terre qui fournisse une masse virtuelle de sorte qu'un convertisseur puisse fonctionner à des tensions d'élément plus basses. Cette pile peut être une pile unicellulaire, une pile unicellulaire universelle, une pile multicellulaire ou une pile hybride multicellulaire.
