Embodiment Construction

[0033] exist image 3 In, a battery 300 with an integrated switching converter topology 305 according to a first embodiment of the invention is shown. like image 3As shown, the principle of powering the battery modules 103 will be applied by means of a switching converter topology 305 located not on each battery module 102, but by means of a switching converter topology 305 located on each battery pack 101. The positive outputs of the battery packs 101 are respectively connected to the secondary side 304 of the switching converter topology. The switching converter topology 305 is preferably designed as a flyback converter, and furthermore, vividly speaking, although there is only one secondary coil 303 , the secondary side is tripled corresponding to three battery packs 101 . However, there is one diode 301 for each battery pack 101 , which serves as the output diode of the switching converter topology 305 and is connected in a conducting direction in the direction towards ...

Abstract

A battery is proposed which has a plurality of battery modules arranged in a plurality of battery packs, which can be selectively activated or deactivated by means of a control device, wherein in the activated state the battery module voltages of the individual battery modules form a The output voltage of the corresponding battery pack of the battery. The battery includes a switching converter topology coupled to the battery pack configured to selectively generate current flow into one or more of the plurality of battery packs. Furthermore, a method for operating a battery is proposed, in which the output voltages of a plurality of battery strings are adjusted or maintained in a suitable manner by controlling the corresponding battery modules in such a way that a predetermined battery voltage is supplied by means of the switching converter topology A selection of banks provides electrical current, the selection including one or more battery banks.

Description

technical field [0001] The invention relates to a battery with a plurality of battery modules arranged in a plurality of battery packs, the battery modules can be selectively activated or deactivated by means of a control device, wherein the battery module voltage of the individual battery modules in the activated state forms the output voltage of the corresponding battery pack of the battery. Furthermore, the invention relates to a corresponding method for driving a battery. Furthermore, the present invention relates to a vehicle having a battery. Background technique [0002] In the future, more and more new batteries will be used, whether in stationary applications such as wind power plants, in vehicles such as hybrid and electric vehicles, or in consumer products such as notebooks and mobile phones. Very high demands are made in terms of reliability, safety, performance and service life. Batteries utilizing lithium-ion technology are especially suitable for this task....
