Comparison between the functionally integrated battery and the state of the art The functional integration approach eliminates structural redundancies and therefore increases the available package space in lateral vehicle direction. For the research vehicle the additional package space is about 70–80 mm.
To integrate the vehicle floor panel into the lid of the battery housing, the battery must be enlarged to match the layout of the vehicle floor panel. To achieve a weight reduction, a full integration of the floor panel is to be pursued.
The goal of this paper is to present a novel concept for a functionally integrated battery housing, in which the aspects of lightweight design and improving space-efficiency on full vehicle level are pursued by reducing structural redundancies between the vehicle body and the battery housing.
The sills and the fillets that transfer forces in the cross-car beam in front of the battery into the sills are very substantial. What we don’t see is how the top panel of the battery is fixed to the cross beams. The mounting points and body structure suggest that there are further opportunities for integration.
To comply with the current standards, it is essential that the chosen direction of functional integration is targeted form the vehicle body towards the battery housing and not vice versa. As such, the battery can be designed as a sealed system and the leak tightness of the battery can be ensured.
By contrast, a full integration of the vehicle rocker into the side frame of the battery system is not beneficial. Several components of the floor assembly are attached to the vehicle rocker, for instance the A-pillar, B-pillar and seat cross members.
