Battery assembly
View Patent ↗A battery assembly for installation into a battery structural space of a transportation vehicle body having a battery housing accommodating a number of battery modules, wherein the battery housing has a smaller dimension along a vehicle longitudinal direction than the battery structural space, such that a free space is formed in the battery structural space, and wherein a shear panel element is provided as an areal bridging and stiffening of the free space.
1. A battery assembly for configured installation into a battery structural space of a transportation vehicle body, the battery assembly comprising:
a battery housing accommodating a plurality of battery modules, wherein the battery housing has a smaller dimension along a vehicle longitudinal direction than the battery structural space so that a free space is formed in the battery structural space; and
a shear panel element configured to provide areal bridging and stiffening of the formed free space by transmitting shear loads to effect torsional flexural buckling load-bearing capacity of the formed free space.
2. The battery assembly of claim 1 , wherein the shear panel element is fastened by screws or fastenable by screws to the battery housing and/or to the transportation vehicle body.
3. The battery assembly of claim 1 , wherein the shear panel element is a metal shear plate.
4. The battery assembly of claim 1 , wherein the shear panel element has a frame structure arranged or arrangeable at least at three sides along the inner periphery of the free space.
5. The battery assembly of claim 1 , wherein the shear panel element includes struts or tie members which cross one another.
6. The battery assembly of claim 5 , wherein the shear panel element is two struts or tie members which cross one another diagonally in the free space.
7. The battery assembly of claim 1 , wherein a second shear panel element is provided as an areal bridging and stiffening of the free space, wherein the shear panel elements are arranged or arrangeable spaced apart from one another along a vehicle transverse direction.
8. An electrically driven or driveable transportation vehicle having a transportation vehicle body with a battery structural space and the battery assembly of claim 1 mounted in the battery structural space.
9. A modular battery assembly system configured for installation into a battery structural space of a transportation vehicle body of a transportation vehicle, the modular battery assembly system comprising:
a first battery assembly of a first battery power level, with a first battery housing which substantially completely fills the battery structural space; and
at least one second battery assembly of a relatively lower battery power level than the first battery power level,
wherein the at least one second battery assembly includes a second battery housing accommodating a plurality of battery modules, wherein the second battery housing has a smaller dimension along a vehicle longitudinal direction than the transportation vehicle's battery structural space thereby forming a free space therein, and a shear panel element configured to provide areal bridging and stiffening of the formed free space by transmitting shear loads to effect torsional flexural buckling load-bearing capacity of the formed free space.
10. The battery assembly system of 9 , wherein the plurality of battery modules includes fewer than twelve battery modules accommodated in the second battery housing.
11. The battery assembly system of claim 9 , wherein the shear panel element is fastened by screws or fastenable by screws to the second battery housing and/or to the transportation vehicle body.
12. The battery assembly system of claim 9 , wherein the shear panel element is a metal shear plate.
13. The battery assembly system of claim 9 , wherein the shear panel element has a frame structure arranged or arrangeable at least at three sides along the inner periphery of the free space.
14. The battery assembly system of claim 9 , wherein the shear panel element includes struts or tie members which cross one another.
15. The battery assembly system of claim 14 , wherein the shear panel element is two struts or tie members which cross one another diagonally in the free space.
16. The battery assembly system of claim 9 , wherein a second shear panel element is provided as an areal bridging and stiffening of the free space, wherein the shear panel elements are arranged or arrangeable spaced apart from one another along a vehicle transverse direction.
