Es ist ein Batteriepack zur Stromversorgung eines Feldgeräts und zur Bereitstellung einer Ausgangsspannung an das Feldgerät gegeben. Das Batteriepack weist eine Stromquelle und einen Spannungswandler auf, der ausgeführt ist, eine erste Spannung auf eine zweite Spannung zu wandeln, wobei die erste Spannung an der Stromquelle anliegt. Weiterhin weist das Batteriepack einen Spannungsregler auf, der einen aktivierten Modus und einen abgeschalteten Modus aufweist. Außerdem weist das Batteriepack eine Steuereinrichtung auf, wobei die Steuereinrichtung ausgeführt ist, auf ein Signal des Feldgeräts den Spannungsregler in den aktivierten Modus zu überführen und wobei die Ausgangsspannung nach Überführen des Spannungsreglers in den aktivierten Modus die zweite Spannung ist und nach Überführen des Spannungsreglers in den abgeschalteten Modus die erste Spannung ist.
摘要:
The invention relates to a method for transferring a minimum and/or a maximum value of a battery system parameter from a quantity of values of said battery system parameter in a battery system (1) comprising a plurality of battery cells (2), wherein the minimum value of the battery system parameter is transferred via a first data line (3) and/or the maximum value of the battery system parameter is transferred via a second data line (4). A periodic clock signal (5) having a permanent period duration (16) is thus generated. In order to transfer the minimum value of the battery system parameter for each value of the battery system parameter phase-synchronously to the clock signal (5), a first signal (17', 17", 17'"), which can assume either a first signal state (18) or a second signal state (19), is generated and given to the first data line (3), and/or in order to transfer the maximum value of the battery system parameter for each value of the battery system parameter phase-synchronously to the clock signal (5), a second signal (21', 21", 21'"), which can assume either a first signal state (22) or a second signal state (23), is generated and given to the second data line (4). The invention further relates to a battery system which is designed to carry out the method according to the invention.

摘要:
A battery system includes an enclosure conforming to a standard form factor, such as a group specified by the Battery Council International. A battery and at least one ultracapacitor are disposed in the enclosure and interconnected to provide electrical energy at battery terminals. Control and/or regulation circuitry may also be provided in the enclosure and interconnected with the battery and ultracapacitor. The battery system may be designed to retrofit existing batteries, such as in vehicular and other applications. The use of a standard form factor allows for little or no alteration of the physical and electrical systems into which the battery system is placed.
