Title
(EN) ENERGY STORAGE SYSTEM AND METHOD TO IMPROVE BATTERY PERFORMANCE
(FR) SYSTÈME DE STOCKAGE D'ÉNERGIE ET PROCÉDÉ PERMETTANT D'AMÉLIORER LES PERFORMANCES DE BATTERIE
Abstract
(EN)
A battery system and method may be shown and described. Two or more batteries may be connected in an identical configuration to an output device. The batteries may be controlled by a control unit or logic chip which may be configured to operate in two phases. In the first phase, the two or more batteries may be connected in series. In the second phase, the two or more batteries may be connected in parallel. Switches may be connected to the positive and negative terminals of the batteries to switch the configuration from series to parallel, and vice-versa. A control unit may switch between the two phases at any desirable frequency to produce a desired output voltage and amperage. The switching speed between the two phases may be any number of rotations per second.
(FR)
La présente invention concerne un système et un procédé de batterie. Deux batteries ou plus peuvent être connectées dans une configuration identique à un dispositif de sortie. Les batteries peuvent être commandées par une unité de commande ou une puce logique qui peut être configurée pour fonctionner en deux phases. Dans la première phase, les deux batteries ou plus peuvent être connectées en série. Dans la seconde phase, les deux batteries ou plus peuvent être connectées en parallèle. Des commutateurs peuvent être connectés aux bornes positive et négative des batteries afin de commuter la configuration de série à parallèle, et vice-versa. Une unité de commande peut commuter entre les deux phases à n'importe quelle fréquence souhaitable afin de produire une tension et une intensité de sortie souhaitées. La vitesse de commutation entre les deux phases peut être un nombre quelconque de rotations par seconde.
