Title (EN) AUTOMATIC DC RESISTANCE COMPENSATION
(FR) COMPENSATION AUTOMATIQUE DE RÉSISTANCE EN COURANT CONTINU
Abstract:
(EN) The uneven charge and discharge from non-collocated batteries within an HMD can be solved by monitoring the DC current on the paths coupled to the first battery and the second battery and making an adjustment in the path resistance to equalize, or at least reduce, the difference between the currents on the two paths. Aspects of the technology described herein monitor current on paths from two or more non-collocated batteries. When the currents are different, resistance is dynamically added to the path with the higher current to equalize the current in the two paths. The monitoring and resistance adjustment can occur during discharge from a battery to a load and during battery recharge.
(FR) Le problème de charge et de décharge irrégulières à partir de batteries non contigües dans un visiocasque peut être résolu par la surveillance du courant continu sur les trajets couplés à la première batterie et à la seconde batterie et par la réalisation d'un ajustement de la résistance de trajet pour égaliser, ou au moins réduire, la différence entre les courants sur les deux trajets. Des aspects de la technologie selon la présente invention surveillent le courant sur des trajets à partir de deux batteries non contigües ou plus. Lorsque les courants sont différents, la résistance est ajoutée dynamiquement au trajet avec le courant supérieur pour égaliser le courant dans les deux trajets. La surveillance et l'ajustement de la résistance peuvent se produire pendant la décharge d'une batterie vers une charge et pendant la recharge de la batterie.
