Battery housing part
View Patent ↗A battery housing part ( 10 ) for a traction battery has opposite first and second vertically aligned housing walls ( 12, 14 ) for laterally covering battery cells, a second housing wall ( 14 ) from a floor level ( 28 ) to a cover level ( 30 ) and horizontally from a left side level ( 32 ) to a right side level ( 34 ). At least one reinforcement profile ( 18 ) is connected to the first housing wall ( 12 ) and the second housing wall ( 14 ) for at least partial dissipation of impact forces in the case of a crash of the motor vehicle. The reinforcement profile ( 18 ) is spaced apart both from the floor level ( 28 ) and the cover level ( 30 ) and from the left side level ( 32 ) and the right side level ( 34 ).
1. A battery housing part for a traction battery for a purely electric drive of a motor vehicle, comprising:
opposite first and second housing walls for laterally covering battery cells, the first and second housing walls extending vertically from a floor level to a cover level and horizontally from a left side level to a right side level; and
at least one reinforcement profile connected to the first and second housing walls for at least partial dissipation of impact forces in a crash of the motor vehicle, the reinforcement profile being spaced apart both from the floor level and the cover level and from the left side level and the right side level
wherein the first housing wall, the second housing wall and the reinforcement profile are manufactured by aluminum high pressure continuous casting.
2. The battery housing part of claim 1 , wherein the reinforcement profile is configured in one piece with the first housing wall and/or with the second housing wall.
3. The battery housing part of claim 1 , wherein the first and second housing walls each have a lower end for fastening to a housing floor and an upper end for fastening to a housing cover.
4. A traction battery for a purely electric drive of a motor vehicle, comprising a battery housing with the battery housing part of claim 1 , and at least one battery cell arranged in the battery housing, the reinforcement profile running past the at least one battery cell.
5. A battery housing part for a traction battery for a purely electric drive of a motor vehicle, comprising:
opposite first and second housing walls for laterally covering battery cells, the first and second housing walls extending vertically from a floor level to a cover level and horizontally from a left side level to a right side level; and
at least one reinforcement profile connected to the first and second housing walls for at least partial dissipation of impact forces in a crash of the motor vehicle, the reinforcement profile being spaced apart both from the floor level and the cover level and from the left side level and the right side level, wherein the reinforcement profile is of substantially rod-shaped configuration with a substantially T-shaped cross-sectional area.
6. The battery housing part of claim 5 , wherein the reinforcement profile is configured in one piece with the first housing wall and/or with the second housing wall.
7. The battery housing part of claim 5 , wherein the first housing wall, the second housing wall and the reinforcement profile are manufactured by aluminum high pressure continuous casting.
8. The battery housing part of claim 5 , wherein the first and second housing walls each have a lower end for fastening to a housing floor and an upper end for fastening to a housing cover.
9. A traction battery for a purely electric drive of a motor vehicle, comprising a battery housing with the battery housing part of claim 5 , and at least one battery cell arranged in the battery housing, the reinforcement profile running past the at least one battery cell.
10. A battery housing part for a traction battery for a purely electric drive of a motor vehicle, comprising:
opposite first and second housing walls for laterally covering battery cells, the first and second housing walls extending vertically from a floor level to a cover level and horizontally from a left side level to a right side level;
at least one reinforcement profile connected to the first and second housing walls for at least partial dissipation of impact forces in a crash of the motor vehicle, the reinforcement profile being spaced apart both from the floor level and the cover level and from the left side level and the right side level; and
at least one bulkhead plate fastened to the first and second housing walls for separating two battery cells that are arranged laterally next to one another, the bulkhead plate being configured for at least partial dissipation of impact forces in a crash of the motor vehicle and being spaced apart from the left side level and the right side level.
11. The battery housing part of claim 10 , the bulkhead plate bears against the reinforcement profile.
12. The battery housing part of claim 11 , wherein the bulkhead plate is connected releasably to the first and second housing walls and is inserted linearly into first and second guides disposed respectively on the first and second side walls.
13. The battery housing part of claim 12 , wherein the bulkhead plate is spaced apart from the floor level and the cover level.
14. A traction battery for a purely electric drive of a motor vehicle, comprising a battery housing with the battery housing part of claim 6 , and at least one battery cell arranged in the battery housing, the reinforcement profile running past the at least one battery cell.
15. The battery housing part of claim 10 , wherein the reinforcement profile is configured in one piece with the first housing wall and/or with the second housing wall.
16. The battery housing part of claim 10 , wherein the first housing wall, the second housing wall and the reinforcement profile are manufactured by aluminum high pressure continuous casting.
17. The battery housing part of claim 10 , wherein the first and second housing walls each have a lower end for fastening to a housing floor and an upper end for fastening to a housing cover.
