Embodiment Construction

[0032] figure 1 A perspective view of an example of a battery case 1 for a battery according to the present invention is shown. Such a battery can be part of a motor vehicle and in this respect serve to provide electrical energy or power for an electric drive system of the motor vehicle. The battery case 1 includes a case top 1a and a case bottom 1b. Each of the two housing parts 1 a , 1 b of the battery housing 1 has a base body 2 which extends in the direction of extension E. FIG. In the example shown, the direction of extension E corresponds to the longitudinal direction L along which the base body 2 of the battery housing 1 in each case extends. The base body 2 delimits a housing interior 3 at least partially in the interior. Thus, in the example shown, the two housing parts 1a, 1b together form a multi-part housing 13 which can comprise, in addition to the housing parts 1a, 1b, one or two covers (in figure 1 (not shown in ), the cover can be fixed to the two end faces...

Abstract

The invention relates to a battery housing (1) for a 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).

Description

technical field [0001] The invention relates to a battery casing for a battery and to a method for producing such a battery casing. Background technique [0002] A battery for a motor vehicle, that is to say a battery for supplying electrical energy to the electric drive system of the motor vehicle, usually comprises a battery housing which defines an interior space of the housing. Conventional electrical components of the battery are arranged in this housing interior of the battery housing and are electrically insulated from the external environment by the battery housing and are mechanically protected from environmental influences. In this case, an internal pressure higher than the pressure of the external environment may prevail in the housing interior, and the battery housing must be designed to be pressure-resistant. [0003] Against this background, plastic battery cases provided with reinforcing ribs have been used for some time. Such battery housings are usually pr...
