Embodiment Construction

[0034] figure 1 A motor vehicle 2 with a traction battery 4 is shown. The traction battery 4 has a plurality of battery modules 6 , also called battery modules, of which only two battery modules 6 are shown for better clarity.

[0035] Each battery module 6 in turn has a plurality of prismatic cells 8 , wherein every five cells represents a battery module. The batteries 8 each supply a voltage at their battery terminals 10 . The cells 8 of each battery module are here connected in series, for example. The cells are connected in parallel and / or in series with one another in variants which are not shown in detail. The batteries 8 coupled to each other are electrically connected to the two terminals 14 of the battery module 6 by means of current collectors 12 , so that a voltage is applied to the terminals 14 according to the coupling of the batteries 8 . Terminals 14 of battery modules 6 are in turn electrically connected to one another by means of high-voltage connectors 16...

Abstract

The invention relates to a battery pack module (6) comprising a terminal (14) having a contact section (36) for electrically connecting to a high-voltage connector (16); a housing (40) as a contact guard for the contact section (36), the housing (40) having a housing cover (42) which is arranged at a distance from the contact section (36) and forms a receiving chamber (44) for a high-voltage connector (16) between the contact section (36) and the housing cover (42), a housing longitudinal wall (48) of the housing (40) has a slit-shaped first cutout (50) for accommodating a high-voltage connector (16) in the receiving chamber (44), wherein the housing longitudinal wall (48) covers the contact section (36) in a mounting direction (E) of the high-voltage connector, and the housing cover (42)has a second cutout (52) for engaging the high-voltage connector (16) with the contact section (36). The invention further relates to an electrically driven motor vehicle (2) having a traction battery(4) having such a battery pack module (6).

Description

technical field [0001] The invention relates to a battery module with terminals. The invention also relates to an electrically driven motor vehicle, the traction battery of which has such a battery module. Background technique [0002] Electric vehicles usually have a traction battery for supplying electric energy to an electric motor for driving the vehicle. An electrically driven motor vehicle is to be understood here in particular as an electric vehicle (BEV, pure electric vehicle) in which only the energy required for driving is stored in the traction battery, an electric vehicle with a range-extending device (REEV, range-extended electric vehicle) , a hybrid vehicle (HEV, hybrid electric vehicle), a plug-in hybrid vehicle (PHEV, plug-in hybrid electric vehicle) and / or a fuel cell vehicle (FCEV, fuel cell electric vehicle), which is The electrical energy generated by the fuel cell is temporarily stored in the traction battery. [0003] Such a traction battery is suita...
