Abstract

The invention relates to a high-voltage battery (1) for a motor vehicle and to a motor vehicle having such a high-voltage battery (1). According to the invention, the high-voltage battery (1) comprises at least two cell groups (5, 7, 18, 20) having respective battery cells that are electrically connected to each other. The high-voltage battery (1) further comprises an electronic module (8) to which at least two cell groups (5, 7, 18, 20) are connected, said electronic module providing at least one connection (9, 15) for connecting the high-voltage battery (1) to an electrical network (10, 12)outside the battery. Furthermore, it is provided that the electronic module (8) is arranged between the at least two cell groups (5, 7, 18, 20).

Description

technical field [0001] The invention relates to a high-voltage battery for a motor vehicle and a motor vehicle with such a high-voltage battery. Background technique [0002] High-voltage batteries for motor vehicles are becoming more and more common, for example in the form of traction batteries for electric vehicles. In order to provide both sufficient power and sufficient energy, ie sufficient driving range, such high-voltage batteries have considerable space requirements. This creates special challenges for the packaging, ie for the arrangement of all components and components of the motor vehicle. At the same time, the total energy content of such high-voltage batteries continues to increase, leading to special challenges in terms of operational safety and reliability. Another challenge lies in the significant weight of today's high voltage batteries. Weight reduction is therefore a constant challenge in order to enable efficient operation of motor vehicles with driv...
