EV battery size and cost

Being checking a bit on EVs now that Tesla is hot (I think >$2k/share is a joke, you read it here first :)). Still, the EV (which BTW were not invented by Tesla) are cool. Even Teslas are cool (just the stock price is a joke). Note: I am checking also FCEV (look super cool too). 

Anyhow, quick calculation from the offering on this site (they explain it really well so you just can read it there). A Tesla 5.3kWh (444 batteries as 74p6s) pack costs $1580 ($300/kWh) and is 68 x 28 x 7.5 cm. 10 of these packs would give you about 53kWh which is close to Model 3 smallest battery (50kWh) and can take you (if you believe the BS-EPA rating from Tesla) to 354Km. Would love to see you try that, Tesla fan ;) but still pretty good even if falls short of that (see bottom of this post). Assuming same "marketing" trickery, we can guess we can get about 275 km with that battery pack.

So, to summarize it, it takes about $57 and about 0.5 liter of volume per km of autonomy. 

Notice though that this is for the full Tesla module. In the same website we can check the price of the individual cells (Panasonic 18650): 200 cells (3Ah/cell, or ~2.3kWh) for $600. This is actually not much cheaper than just buying the Tesla module, about $1330 for the 444 cells on that module and you got everything else with it (cooling, assembly...), done on the Gigafactory.

So, what to do with this stupid battery? ;)

• Awesome, I repeat, really awesome video of how to make an electric catamaran. Warning: if you watch it, you may not be able to avoid building one. You've been warned...
• Or how about an eBike? :)
• Or an eFoil?
• Or an eWaterBike?

Seriously!

PS.: On the range (what I call BS-EPA), this video measures few cars in a real life scenario. The link should bring you straight into the results part. As summary:

1. Nissan Leaf: 62kWh, 208 miles in the test, 87% of the EPA promised range (what I call the BS-EPA range).
2. Jaguar I-Pace: 90kWh, 223, 76%
3. Mercedes EQ: 80kWh, 194, 75% 
4. Audi e-tron: 95kWh, 206, 81%
5. Kia e-Niro: 64kWh, 255, 90%
6. Tesla model 3 Long range: 75kWh, 270, 78% 

Based on #6, the real range would be 78% of 354km = 276km
