Battery racks - DFA GmbH

Assembly method
Whatever your installation, use these simple guidlines when calculating your preferred configuration.
1. From the data in this publication, define the total number of cells in the battery.
2. Divide the length of the available installation area by the cell length (normal mount) or width (crosswise mount).
This gives the maximum number of cells per row.
3. Divide the width (depth) of the available area by the cell width (normal mount) or length (crosswide mount).
This will give the maximum number of rows.
For example
If we consider a cabinet with three shelves: each shelf has a length of 400 mm and a width 380 mm. The battery
comprises of 90 cells type SBM 15 (figure 3).
Figure 3
The SBM 15-2 (two cell blocks)
has a lenght of 74 mm
and a width of 123 mm.
W = 380 mm
Each shelf can have in its length
400/74 = 5 of the 15-2 two cell
blocks.
Each shelf can have in its width
380/123 = 3 rows of cell blocks.
L = 400 mm
Thus each shelf can have
5 x 3 = 15 two cell blocks = 30 cells.
Whilst this is an ideal example, the calculation formula can be applied to all rack, cabinet and free-standing installations.
For engineering assistance on complex layouts, please contact the company or its agent.
When ordering a battery rack, please specify the battery type and the preferred rack configuration (see pages 26 - 27).
If your battery is being assembled in a cabinet, or is free-standing, please specify the number of rows, cells per row and
total number of cells. This will ensure that all necessary inter-row and inter-tier flexible connectors are provided.
