Abstract
(DE)
Verfahren zum Betreiben eines elektrischen Energiespeichers, der zumindest zwei parallel geschaltet angeordnete elektrische Energiespeichermodule (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10) und Anschlussmittel aufweist, wobei zuerst abgefragt wird, welche elektrischen Energiespeichermodule (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10) betriebsbereit sind, wobei danach eine erste Spannung (U1) eines betriebsbereiten elektrischen Energiespeichermoduls (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10) bestimmt wird, die größer oder gleich der Spannung (U) aller betriebsbereiten elektrischen Energiespeichermodule (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10) ist, wobei danach diejenigen betriebsbereiten elektrischen Energiespeichermodule (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10) ausgewählt werden, deren Spannung innerhalb eines Spannungsbereichs (ΔU) unterhalb der ersten Spannung (U1) liegt, wobei danach die ausgewählten elektrischen Energiespeichermodule (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10) elektrisch leitend mit den Anschlussmitteln verbunden werden.
(EN)
The invention relates to a method for operating an electrical energy store, which has at least two electrical energy storage modules (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10) arranged connected in parallel and connection means, wherein it is first queried which electrical energy storage modules (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10) are operationally ready, a first voltage (U1) of an operationally ready electrical storage module (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10) then being determined, which is greater than or equal to the voltage (U) of all operationally ready electrical energy storage modules (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10), those operationally ready electrical energy storage modules (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10) then being selected which have a voltage below the first voltage (U1) within a voltage range (ΔU), the selected electrical energy storage modules (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10) then being electrically conductively connected to the connection means.
