I wrote that it involves aftermarket charger.
But the principle remains the same with a bit heavier cars.
A smaller battery, on a smaller, lighter vehicle which gets a lot of kms per kwh can potentially be spending less, or equal time charging than bigger cars per km of travel in daily use.
And they will have the advantage of not killing its battery with 3C charging while still proving adequate kms/per minute charging.
Hyundai Ioniq is a good example.
That's why I see mainstream EV economy class to spring around 15-30 kwh battery sizes, simple uncooled/air cooled LFP battery packs, along with moderately fast charging, and aim at high real world km/kwh digits.
- Yaggo 5y agoI think we both agree with the principle of smaller batteries being very usable for many EV. Twizy is just a bit apples vs oranges. Ioniq, especially with the smaller/older 28 kWh battery is very impressive, considering its age and cost. Low consumption & quick charging (despite being air-cooled!). Still, if you want to travel long distances as quickly as possible, bigger battery combined with a sleek car such as Model 3 gives you an advantage because you can hop from charger to charger using the lower end of your battery capacity with extremely fast charging speeds. Smaller battery needs to be charged to higher SOC to make it to next charger, which is typically slower (so called "taper").
