Traction battery and vehicle having a traction battery
View Patent ↗A traction battery of an electrically or semi-electrically driven vehicle includes several battery modules arranged one behind the other in a longitudinal direction of the vehicle. Each of the battery modules extends in a transverse direction of the vehicle between a left and a right vehicle longitudinal support, as well as a central battery control device connected to the battery modules. Each of the battery modules includes on its two opposing front faces a connection region with an electrical connector configured for electrical contacting. The traction battery includes, in the region of each of the two front faces of the battery modules, at least one respective busbar, which extends transversely to the connection regions and parallel to one of the vehicle longitudinal members and is configured so as to electrically connect at least some of the battery modules to one another and/or to the central battery control device.
1 . A traction battery for an electrically or semi-electrically driven vehicle, said traction battery comprising:
a central battery control device;
a plurality of battery modules connected to the central battery control device, the plurality of battery modules arranged one behind the other in a longitudinal direction of the vehicle, each battery module comprising at least one sealed battery module housing and at least one battery cell housed within the battery module housing, wherein each of the battery modules is configured to extend in a transverse direction of the vehicle between a left and a right vehicle longitudinal member;
wherein each of the battery modules includes two opposing front faces, and a connection region disposed on both of the two opposing front faces, each connection region including an electrical connector;
at least one respective busbar disposed in a region of each of the two front faces of the battery modules, which at least one respective busbar extends transversely to the connection regions and is substantially parallel to one of the vehicle longitudinal members and is configured to electrically connect at least two of the battery modules to one another and/or to the central battery control device; and
a respective sealed conduit housing in the region of each of the two front faces of the battery modules, which respective sealed conduit housing is mechanically connected to the connection regions of the battery modules and within which at least one of the busbars is respectively housed.
2 . The traction battery according to claim 1 , wherein each of the battery modules comprises a battery cell controller.
3 . The traction battery according to claim 2 , wherein each of the two conduit housings comprises a housing bottom shell and a housing lid that is releasably fastened to the housing bottom shell.
4 . The traction battery according to claim 3 , wherein the housing bottom shell constitutes an electromagnetic shield.
5 . The traction battery according to claim 3 , further comprising a shielding element arranged within the conduit housing, which shielding element is electrically connected to the conduit housing and constitutes an electromagnetic shield.
6 . The traction battery according to claim 2 , wherein the battery cell controller of each of the battery modules is arranged within one of the conduit housings.
7 . The traction battery according to claim 1 , wherein each of the battery modules comprises a plurality of battery cells arranged one behind the other in the vehicle longitudinal direction and/or adjacent to one another in the vehicle transverse direction.
8 . The traction battery according to claim 7 , wherein the battery cells are arranged as a battery cell stack, wherein each of the battery cell stacks comprises at least two battery cells positioned one above the other in a vehicle vertical direction.
9 . The traction battery according to claim 1 , further comprising at least one sealing element that is respectively arranged between the conduit housings and the connection regions of the battery modules.
10 . A vehicle having a fully electric or semi-electric drive apparatus and a traction battery configured so as to provide electrical power to the drive apparatus, wherein the traction battery is configured according to claim 1 .
