Problems solved by technology

However, in the case of mechanical damage to the battery pack, such contact protection may no longer be granted, wherein the partially damaged battery pack itself may still have a voltage in the high-voltage range
[0004] The HV traction battery in an electric vehicle can cause an electrical hazard, for example, to rescuers in a crash if the housing is damaged and therefore contact protection is no longer provided

Embodiment Construction

[0030] figure 1 A battery pack 100 is shown, which is arranged in the installation space 3 . Here, by figure 1 A separating device 10 for separating a plurality of battery modules 2 connected in series is clearly visible, in which battery modules 2 are electrically connected to one another via releasably pluggable module connectors 1 . The separating device 10 has a separating rail 4 displaceable in its longitudinal direction 20 , which is arranged centrally between the battery modules 2 on a central axis 7 . The separation device 10 is arranged along one side of the battery module 2 and is mechanically connected with a plurality of module connectors 1 traversing the separation device. The electrical connection via the releasably pluggable modular connector 1 is detachable by movement of the separating rail 4 in its longitudinal direction 20 . The battery pack 100 includes a battery control unit BCU 15 in addition to the battery module 2 . During the deformation of the ins...

Abstract

The invention relates to a battery pack (100) with a separation device (10) for separating a plurality of battery modules (2) connected in series in the battery pack (100), wherein the battery modules (2) are electrically connected to one another via detachably plugged module connectors (1). According to the invention, the separating device (10) has a separating rail (4) which can be displaced in its longitudinal direction (20), the separating device (10) is arranged laterally along the battery modules (2), a plurality of modular connectors (1) are connected to the separating rail (4 ) of the separating device (10) are mechanically connected and the electrical connections can be separated by a movement of the separating rail (4) in the longitudinal direction (20) thereof.

Description

technical field [0001] The invention relates to a battery pack with a separation device for the separation of a plurality of battery modules connected in series in the battery pack, wherein the battery modules are electrically connected to each other via releasably pluggable module connectors and have an electrical drive devices and vehicles with such battery packs. Background technique [0002] For many applications, electrochemical cells are connected in series to form battery modules and these are in turn connected in series to form battery packs. In this way, high voltage batteries with output voltages of several hundred volts can be constructed. HV traction batteries employed in the automotive industry for vehicles with electric drive usually have this structure. [0003] Typically, components of the battery pack that are subject to high voltages are protected from contact. However, in the case of mechanical damage to the battery pack, such contact protection may no ...
