 The EPA publishes the documentation sent in by the automakers for a “certificate of conformity”. Basically it’s a document where the automaker says “Hey, here’s some numbers on our engine, it meets EPA requirements”. This [document for the 2020 Model 3 LR AWD](https://dis.epa.gov/otaqpub/display_file.jsp?docid=48712&flag=1#page=020) says the battery has a weight of 480kg and it has a density of 150Wh/kg. This amounts to a 480kg * 150Wh/kg = 72kWh battery, although most other websites that I’ve looked at give closer to 75kWh: [75kWh](https://en.wikipedia.org/wiki/Tesla_Model_3#Specifications_table) [75kWh](https://www.evspecifications.com/en/model/0a86df) [73.5kWh](https://ev-database.org/car/1138/Tesla-Model-3-Long-Range-Dual-Motor) [75kWh](https://www.guideautoweb.com/en/makes/tesla/model-3/2020/specifications/long-range-awd/).
 
 I haven’t quite nailed down why there is this discrepancy between Tesla’s documentation and what most other websites give. I want to chalk it up to “manufacturing tolerances and differences” but I haven’t been able to confirm that. Regardless, just when I thought I had the battery capacity figured out, I stumble upon a site that listed both capacity and “usable capacity”... Yep, this rabbit hole goes deeper. <!-- (https://teslamotorsclub.com/tmc/posts/5576513/) -->
-The site was evspecifications.com, and they list a “usable capacity” around 75kWh with a total capacity of 79.5kWh (screenshot below). What’s the difference?
