Title
(EN) BATTERY CHARGING SYSTEM
(FR) SYSTEME CHARGEUR DE BATTERIES
Abstract
(EN)
A battery charging system including a battery of one chemistry type and a battery charger for a different battery type is disclosed. If a battery over-discharge condition or if an electrochemical cell (201, 202, 203, 204) imbalance is detected within the battery, the battery prevents charging by the battery charger by means of a resettable switch (226, 227, 228, 229, 217).
(FR)
Système chargeur de batteries comportant une batterie d'un type chimique et un chargeur de batteries pour un type de batteries différent. Si une condition de sur-décharge de batterie ou un déséquilibre d'une cellule électrochimique (201, 202, 203, 204) sont détectés à l'intérieur de la batterie, celle-ci empêche la charge par le chargeur de batteries au moyen d'un commutateur pouvant être remis à zéro (226, 227, 228, 229, 217).
