Embodiment Construction

[0030] exist image 3 A battery system 10 according to a first embodiment of the invention is shown in FIG. 1 with a battery 11 having three battery packs 20 , in each of which a separating device 140 according to the invention is arranged. A plurality of battery packs 20 are each connectable between positive battery pack terminal 21 and negative battery pack terminal 22 via associated disconnecting devices 140 . here, image 3 A plurality of disconnecting devices 140 shown in , are each directly connected to the positive battery pole 21 .

[0031]Each battery pack 20 includes a plurality of battery modules 30, wherein, in image 3 Only two battery modules 30 per battery pack 20 are shown. Each battery module 30 here includes at least one battery cell (not individually shown in the figure). The battery modules 30 can be connected in series or bridged to the corresponding battery pack 20 via so-called multiple coupling units (not shown separately). In the three-phase embod...

Abstract

The invention relates to a battery (11) having at least one battery pack (20), wherein a plurality of battery modules (30) which can be connected in series are arranged in the battery pack (20), the battery modules each having at least one battery cell battery, wherein the battery pack (20) is connectable between battery pack terminals (21, 22) assigned to the battery pack (21, 22) via at least one disconnecting device (140) assigned to the battery pack (20) A plurality of battery pack terminals (21, 22) of the battery pack can be decoupled and the battery (11) can be connected to the electric machine. The isolating device ( 140 ) is designed as a bidirectional switch device that can be turned off. Therein, in the disconnecting device, a semiconductor switch (150) is arranged in the current path of the battery pack current, and the disconnecting device (140) is further configured for switching on the semiconductor switch (150) independently of the current direction of the battery pack The ground connects the current through the battery pack (20).

Description

technical field [0001] The invention relates to an accumulator with at least one battery pack, wherein a plurality of battery modules which can be connected in series are arranged in the battery pack, each having at least one battery cell, the battery pack being assigned to the battery pack (20 ) at least one disconnecting device (140) is connectable between or decouplable from a plurality of battery pack terminals (21, 22) assigned to the battery pack , and the battery can be connected to a load, especially a motor. Furthermore, the invention relates to a vehicle with such a battery. Background technique [0002] Typically, batteries for hybrid and electric vehicles are referred to as traction batteries because they are used to supply the electric drive. Such accumulators are disclosed, for example, in patents DE 10 2010 027 856 A1 and DE 10 2010 041 014 A1. [0003] In previous patent applications of the same applicant, multi-phase battery systems with stepwise adjustab...
