System for providing direct current at various voltages from batteries in series, comprises a continuos/continuous convertor which is connected such as to equalize battery currents during charge and discharge

Vehicle electrical supplies are taken at 12V and 24V from the terminals (7,8) of a system which has two 12V batteries (1,2) connected in series and charged by an alternator (3). A continuous/continuous push/pull type convertor (4) is connected between the common battery connection and the 12V output...

Zusammenfassung:	Vehicle electrical supplies are taken at 12V and 24V from the terminals (7,8) of a system which has two 12V batteries (1,2) connected in series and charged by an alternator (3). A continuous/continuous push/pull type convertor (4) is connected between the common battery connection and the 12V output terminal (7) and acts to equalize the battery currents while charging and discharging L'invention concerne un dispositif d'alimentation électrique comportant plusieurs niveaux de tension continue de sortie (7, 8) à partir de plusieurs batteries d'accumulateurs (1, 2) connectées en série. Lesdites batteries sont chargées par une tension externe de niveau identique à la plus haute tension des batteries ainsi connectées. Ladite tension externe provenant par exemple d'un alternateur (3). On utilise un convertisseur continu-continu (4) de façon à obtenir un courant de charge (Ich1 , Ich2 ) identique dans toutes les batteries et un courant de décharge également identique dans toutes les batteries.
