A thing that EV makers need to start quoting in their specs is DC charge rate

Posted by Reagen Mar 8 '23, 09:18

It's one thing to list the range but just as important is the fact charge speed. Range and charge rate are in a balancing act. You can make the battery huge but it takes you forever to charge on a road trip (home charging, wgaf when you can charge overnight). 50kWh is a pretty small battery but justified by it being a small car. At a 50kW DC rate, that means you go from 20 to 80% in about 36 minutes. At 150kW, that's 12 minutes and you're getting competitive with gassing up. If you need to make your battery huge cause it's a fucking Hummer, then you need 300kW charging to get you back on the road.

Add in efficiency too. You can obviously do the math if they release the battery size, since you know the range, but - TWuG Mar 8, 09:28 3
- Yeah, that efficiency calculation is going to be the next big consideration for being green. Hummer EV being the obvious worst offender. - Beryllium Mar 8, 09:32 2
  - The Hummer EV is to EVs as the Hummer ICE is to ICE vehicles. It's the conspicuous consumption choice. -- nm - TWuG Mar 8, 09:39 1
    - It's the rolling coal of EVs -- nm - Beryllium Mar 8, 09:44
