Re: battery pack

Thu May 20, 2010 9:34 am

garygid - kind of off topic, but the subassembly supplier really does matter. Have you been following the Toyota stuck accelerator recalls? Japanese produced accelerator pedals do not stick. Canadian produced ones have.

For battery cells, the quality of material available for soldering the leads will matter. If that connection deteriorates, the battery will short or cease to function. Some third world countries do not have the metallurgy production capabilities for pure end products. If the battery assembly is outsourced to Pakistan, the solder may be inferior and could fail sooner.

OK, I understand now, thanks.

Certainly, ongoing quality control at all stages of "construction"
is critical if one wants to produce a quality product.

It would be interesting to know the real story of how the "sticky"
Canadian gas pedals (if any) came to be used in the Prius.

Alright this helps, I guess for practical purposes, AESC is basically Nissan. Anyone know why Nissan would create AESC?

Tesla created a "Tesla Energy Group" division in the company for selling Tesla battery technology to others. Perhaps Nissan is planning something similar, but chose to create a separate company instead of just a division.

Creating a separate company greatly eases intellectual property issues, and is more financially flexible as well.

Because it is a JV (joint venture). Notice that Nissan owns just over 50% ...
1st Leaf : 2/28/2011 to 5/6/2013
2nd Leaf : 5/4/2013 to 3/21/2017
Volt : 3/25/2017 to 5/25/2018
Model 3 : 5/10/2018 to ?

Joint Ventures (most of which don't work, but this one appears to have), are usually formed because two companies, that are not directly competitive, do not have the technical and/or financial resources to solve some issue or enter a market. It also spreads the risk to two parties, instead of having to carry it solo.The nightmare ones are those with a 50/50 ownership split which inevitably leads to a giant clash of egos and gridlock. In this one, the senior partner, Nissan, has more than 50%, which at least puts someone in charge.

Hopefully, this "closely-held" JV will be a big "win" for Nissan.
