Abstract[English]
Systems and methods for operating heterogenous battery packs in parallel Embodiments herein disclose methods and systems for minimizing current distribution variation and mitigation of unnecessary circular currents arising due to heterogeneous batteries (wherein the heterogeneity can be in terms of, but not limited to, makes, chemistries, characteristics, and so on) operated in a parallel connection. Embodiments herein disclose methods and systems for optimizing current distribution and matching Direct Current Internal Resistance (DCIR), and voltage characteristics in a multi-battery parallel operation using one or more compensation, and control methods.[French]
Des modes de réalisation divulguent des procédés et des systèmes permettant de réduire au minimum une variation de distribution de courant et une atténuation de courants circulaires inutiles survenant en raison de batteries hétérogènes (l'hétérogénéité pouvant être en termes de marques, de compositions chimiques, de caractéristiques, etc., sans s'y limiter) fonctionnant en parallèle. Des modes de réalisation de l'invention divulguent des procédés et des systèmes permettant d'optimiser une distribution de courant et de mettre en correspondance une résistance interne à courant continu (DCIR), et des caractéristiques de tension dans un fonctionnement en parallèle à batteries multiples à l'aide d'une ou de plusieurs compensations, et des procédés de commande.
