CyberBeast Battery size Can’t be 122KWH

[henchman24]

Reverse the problem: look at your charging. If charging from 50% to 100% takes 61kWh, then you can extrapolate a 122kWh total capacity.

This won't quite work for two main reasons 50-100% isn't 61kWh (more like 58-59) and charging is never 100% efficient with no reliable tracking of the overhead and losses.

Can someone please help me understand this? 370 wh/mi is awesome efficiency but this doesn’t add up to a 122kwh battery. At 405wh/mile a 122kwh battery should give the stated range of 300 miles. At 370 wh/mile it should be a lot more. Battery seems to be a lot smaller than 122kwh. Thanks

So, you went from 97% down to 9%, for 237.1mi, and the battery used, 87.8kWh works out to ~72% of your battery used. The difference is ~16%.

And the Energy Park display should show 16% used. Did you look to see what that display showed? Would be nice to get confirmation that your battery size is correct.

yes, points to an approx 122KWH pack, which is what we been saying

72% x 1.39 is 100%, 1.39x87.8KWH is 122KWH

Tesla filed docs with EPA as part of certification process; from page 3: battery size 816v x 150 a/h = 122,400 w/h = 122.4 k/Wh

Numbers I came up with using various sources including that doc.
