Along with details on the 2016 Nissan Leaf, Nissan published a video showing us details of the battery pack factory in Smyrna Tennessee. This video happens to show construction of the new 30 kiloWatt-hour battery pack, which we know simply because of the shape of each module. And it happens to show us some interesting details about the Leaf battery pack innards.
The video is at the bottom. I’ve made a few screen captures to walk through what is shown.
The Nissan Leaf pack is not a regular rectangular shape, and it never has been. Some modules are laid horizontally, probably so they’ll sit under the seating area. Another group of modules are laid vertically, probably to fit behind the rear seats.
The new modules for the 30 kWh pack is packaged as 8 cells, in a 2P 4S arrangement. (2 in parallel, 4 in series)
It looks like the machinery is checking battery cell voltage – which would be a necessary step to weed out bad cells.
