Battery pack - who makes them ?

Wed May 19, 2010 6:26 am

For the Nissan Leaf's battery, I understand that AESC is providing the batteries. Does AESC actually make the entire battery pack? Or does Nissan assemble the individual cells together in a pack?

Thanks

I have consolidated your post to the most logical area to prevent multiple threads on the same topic. Welcome to the forum.

AESC is a joint venture between Nissan and NEC.

"Nissan Motor Company, NEC Corporation, and its subsidiary, NEC TOKIN, have signed an agreement to establish a joint-venture company – Automotive Energy Supply Corporation (AESC) – to focus on lithium-ion battery business for wide-scale automotive application by 2009."

It's hard to figure out, but I wouldn't be surprised if they do the pack integration as well... here is their web page on the modules.

Accounting and tax reporting aside, I think we can assume that for practical purposes AESC is Nissan.

This is the important point. It is majority owned by Nissan.

Nissan Motor., Co.:51%/NEC Group 49%


Unlike some other JVs, the thing to note here is that Nissan owns the battery chemistry. They have a JV with NEC to get their know-how on volume manufacturing of batteries.

Even if we know who "assembles" the battery pack, what difference does it make?

Does who makes the headlight assembly, windshield, or steering wheel really matter very much?

The important thing is that they are getting the job done, and that their technology is "close to home".

it matters because Nissan and other manufacturers outsource some parts to smaller companies who specialize in that area. These smaller companies want to know if they can maybe sell thier product to auto giants. For example, if I supply material for a steering wheel, I would like to know if the auto company creates their own steering wheel or if some smaller company designs it. That's why I am curious.

I imagine the specific suppliers, if outside (or inside) the Nissan "umbrella", are not openly listed anywhere.

What specific parts are you wanting to supply to Nissan? (just curious)
