Battery pack for vehicle
View Patent ↗An embodiment battery pack for a vehicle includes a plurality of battery modules disposed in a casing, a casing member provided in the casing to secure rigidity of the casing, and a wiring assembly disposed in the casing member. Another embodiment battery pack for a vehicle includes a plurality of battery modules arranged flatly, a casing surrounding a bottom and lateral sides of the battery modules, a casing member provided lengthwise in the casing along an arranged direction of the battery modules, and a wiring assembly provided in a space defined by a recessed portion recessed inward in a cross-sectional view of the casing member.
1 . A battery pack for a vehicle, the battery pack comprising:
a casing;
a plurality of battery modules disposed in the casing;
a casing member provided in the casing to secure rigidity of the casing; and
a wiring assembly disposed in the casing member,
wherein the casing member is disposed to longitudinally cross an inside of the casing, and
wherein the wiring assembly is connected to a front connector, which is connected to an outside, through a first end of the casing member, and is connected to a power relay assembly through a second end of the casing member.
2 . The battery pack of claim 1 , wherein:
the battery modules are arranged flatly in a single layer; and
the casing member is rectilinearly disposed in a direction parallel to a plane formed by the battery modules and provided with a space to receive the wiring assembly.
3 . The battery pack of claim 1 , wherein the wiring assembly disposed in the casing member is connected to a fuse mounted to a front of the casing through the first end of the casing member.
4 . The battery pack of claim 2 , wherein:
the casing member has a structure in which lateral sides are parallel to the battery modules and a bottom side is open to define an open region in a cross-sectional view; and
the wiring assembly is provided in the open region.
5 . The battery pack of claim 4 , wherein the wiring assembly is provided in the space defined by the open region of the casing member and a mid-plate supporting a bottom of the battery modules.
6 . The battery pack of claim 2 , wherein:
the casing member comprises lateral grooves at lateral sides thereof facing toward the battery modules; and
the wiring assembly is provided in the lateral grooves of the casing member.
7 . The battery pack of claim 6 , wherein the wiring assembly is provided in the space defined by the lateral grooves of the casing member and the battery modules.
8 . A method of forming a battery pack for a vehicle, the method comprising:
disposing a plurality of battery modules in a casing;
disposing a casing member in the casing to secure rigidity of the casing; and
disposing a wiring assembly in the casing member
wherein the casing member is disposed to longitudinally cross an inside of the casing, and
wherein the wiring assembly is connected to a front connector, which is connected to an outside, through a first end of the casing member, and is connected to a power relay assembly through a second end of the casing member.
9 . The method of claim 8 , wherein:
the battery modules are arranged flatly in a single layer; and
the casing member is rectilinearly disposed in a direction parallel to a plane formed by the battery modules and provided with a space to receive the wiring assembly.
10 . The method of claim 9 , wherein
the wiring assembly is connected to a fuse mounted to a front of the casing through the first end of the casing member.
11 . The method of claim 9 , wherein:
the casing member has a structure in which lateral sides are parallel to the battery modules and a bottom side is open to define an open region in a cross-sectional view; and
the wiring assembly is provided in the open region.
12 . The method of claim 11 , wherein the wiring assembly is provided in the space defined by the open region of the casing member and a mid-plate supporting a bottom of the battery modules.
13 . The method of claim 9 , wherein:
the casing member comprises lateral grooves at lateral sides thereof facing toward the battery modules; and
the wiring assembly is provided in the lateral grooves of the casing member.
14 . The method of claim 13 , wherein the wiring assembly is provided in the space defined by the lateral grooves of the casing member and the battery modules.
