Is there any technical reason for limiting the charge rate unless you pay more? I see this is becoming common now. Even Tesla does it. I'd be willing to settle

I'd be willing to settle for the smaller battery as long as charging it was at the same higher rate. Sure, charging sessions are more frequent during long trips, but if you're charging a smaller battery at the same rate then the charging sessions are shorter. So it seems like they're just trying to get more money out of you by limiting the charging rate of the low-end cars.
- magicalhippo 7y agoThe charging rate is related to how many cells the battery pack consists of. Each cell can take a certain charging current, so more cells = higher total current. If they implement the longer range by adding more cells (which I assume they do), then that's your technical reason. Of course, could also just be a way to get more money...
- Tempest1981 7y agoI thought heat was also a factor. If the batteries are liquid-cooled, you can keep them cooler and charge them faster. Is this true? Or do most manufactures/models have battery cooling systems?
- sowbug 7y agoEven Tesla does it. This was last true in 2016, when you could add a dual-charger option to your S or X to increase non-Supercharger charging from 48 amps to 72 amps (dual != double because of battery limitations). Would you mind citing your source?
