US 2021/0344072 A1 · BATTERY HOUSING AND METHOD FOR PRODUCING A BATTERY HOUSING

Abstract

The invention relates to a battery housing (1) for an electrical battery, comprising a basic body (2) which extends in a direction of extent (E) and at least partially delimits a housing interior space (3) on the inside. The battery housing (1) moreover comprises at least one stiffening rib (4), which is shaped integrally on the inside or the outside of the basic body (2) and protrudes from the basic body (2). The stiffening rib (4) of the battery housing (1) runs on the basic body (2) in a rib direction (R) oriented at an angle to the direction of extent (E). In this respect, a body material of the basic body (2) comprises first reinforcing fibres (5), which run substantially in the direction of extent (E) and a rib material of the stiffening rib (4) comprises second reinforcing fibres (6), which run substantially in the rib direction (R).

Dependent claims

Battery housing (1) for an electrical battery, in particular for a motor vehicle,

having a basic body (2) which extends in a direction of extent (E), in particular a longitudinal direction (L), and at least partially delimits a housing interior space (3) on the inside,
having at least one stiffening rib (4), which is integrally shaped on the inside or the outside of the basic body (2), protrudes from the basic body (2) and extends on the basic body (2) in a rib direction (R) oriented at an angle to the direction of extent (E),
wherein a body material of the basic body (2) comprises first reinforcing fibres (5), which run substantially in the direction of extent (E),
wherein a rib material of the stiffening rib (4) comprises second reinforcing fibres (6), which run substantially in the rib direction (R).

1 more element

Method for producing a battery housing (1), in particular according to one of the preceding claims,

comprising the following measures:
a) extruding a body raw material comprising first fibres (5) in a direction of extent (E), in particular a longitudinal direction (L), with the result that a basic body (2) of the battery housing (1) that extends in the direction of extent (E) or longitudinal direction (L) is created, which basic body at least partially delimits a housing interior space (3) of the battery housing (1) on the inside,
b) moulding a rib raw material comprising second fibres (6) onto the basic body (2), with the result that at least one stiffening rib (4) running in a rib direction (R) which is oriented at an angle to the direction of extent (E) is integrally shaped on the inside or the outside of the basic body (2).
