Would there be a business case proposal for dropping the intended capacity in half?
All of these solutions seem to focus on massive packs compared to the Gen1 leaf.
Here’s what I see.
Better density would give a lower overall weight, improving performance
Lower weight may contribute to reduced consumption, possibly equaling the original 24kwh range
Extra space inside the pack allows for passive air cooling and less loading
Costs would be dropped, and a better economic calculation to improve an older car vs a complete vehicle upgrade - which in most cases is simply cheaper overall.
Shipping costs reduced
Tax costs reduced
Lastly - the range offered by a light weight 20kwh pack would be better than double the range of the vast majority of Gen1 owners who might consider this. If 50m/80km is working for them now, getting back to near double that is a great bonus and extends the life by at least another 10yrs
