Electrified vehicle with battery arrangement including guide permitting relative transverse movement of individual modules
This disclosure relates to a battery arrangement for an electrified vehicle. In particular, the battery arrangement includes modules which are configured to move relative to one another in a transverse direction. For instance, an example battery arrangement includes a guide, and first and second battery modules. The guide is arranged at least partially between adjacent surfaces of the battery module housings and is configured to permit the first and second battery modules to slide relative to one another in a transverse direction of the electrified vehicle.
1. A battery arrangement for an electrified vehicle, comprising:
a guide; and
first and second battery modules each including a battery module housing, wherein the guide is arranged at least partially between adjacent surfaces of the battery module housings and is configured to permit the first and second battery modules to slide relative to one another in a transverse direction of the electrified vehicle,
wherein the guide includes a vertical section arranged longitudinally between the adjacent surfaces of the battery module housings, and further includes horizontal projections projecting from ends of the vertical section and configured to restrict vertical movement of the first and second battery modules, and
wherein the adjacent surfaces of the battery module housings include an aft surface of the battery module housing of the first battery module and a fore surface of the battery module housing of the second battery module.
2. The battery arrangement as recited in claim 1 , wherein the guide has an I-shaped cross-sectional profile.
3. The battery arrangement as recited in claim 1 , wherein the first and second battery modules each have a length extending in the transverse direction.
4. The battery arrangement as recited in claim 1 , wherein:
the adjacent surfaces of the battery module housings each include an elongated hole extending in the transverse direction, and
the guide includes an elongated hole extending in the transverse direction.
5. The battery arrangement as recited in claim 4 , further comprising at least one flexible line extending between the first battery module and the second battery module by passing through the elongated holes of the battery module housings and the guide.
6. The battery arrangement as recited in claim 5 , wherein the at least one flexible line is configured to connect the first battery module to the second battery module either fluidly, mechanically, or electronically.
7. The battery arrangement as recited in claim 4 , wherein the elongated holes of the battery module housings and the guide are at least partially aligned with one another in a normal operating condition.
8. The battery arrangement as recited in claim 1 , wherein the first and second battery module housings are mechanically connected together by at least one shear bolt configured to break upon application of a force exceeding a predetermined amount.
9. The battery arrangement as recited in claim 1 , wherein the first and second battery modules are arranged within a battery housing less rigid in the transverse direction than each of the first and second battery modules and the guide.
10. The battery arrangement as recited in claim 9 , wherein the guide is at least as rigid as the first and second battery modules.
11. The battery arrangement as recited in claim 9 , wherein the battery housing tapers in a front direction.
12. The battery arrangement as recited in claim 9 , wherein the battery arrangement includes at least one additional battery module within the battery housing.
13. The battery arrangement as recited in claim 1 , wherein the guide is formed separately from the battery module housings, and the guide is configured to move independently of the first and second battery modules.
14. An electrified vehicle, comprising:
a battery arrangement positioned on or under a subfloor of the electrified vehicle, the battery arrangement comprising:
a guide; and
first and second battery modules each including a battery module housing, wherein the guide is arranged at least partially between adjacent surfaces of the battery module housings and is configured to permit the first and second battery modules to slide relative to one another in a transverse direction of the electrified vehicle,
wherein the guide includes a vertical section arranged longitudinally between the adjacent surfaces of the battery module housings, and further includes horizontal projections projecting from ends of the vertical section and configured to restrict vertical movement of the first and second battery modules, and
wherein the adjacent surfaces of the battery module housings include an aft surface of the battery module housing of the first battery module and a fore surface of the battery module housing of the second battery module.
15. The electrified vehicle as recited in claim 14 , wherein the guide has an I-shaped cross-sectional profile.
16. The electrified vehicle as recited in claim 14 , wherein the guide is formed separately from the battery module housings, and the guide is configured to move independently of the first and second battery modules.
17. The electrified vehicle as recited in claim 14 , wherein the electrified vehicle includes front and rear axles extending in the transverse direction.
