Tesla semi is almost triple that (around 900kWh) and charges to 70% in 30 minutes with their megawatt charger. So it should be able to easily handle that use case.
- cogman10 4y agoThe 1 hour charge rate is a function of the battery chemistry ultimately. Whether the battery is 10kWh or 1000kWh, you can do the 0->70% in 30 minutes so long as you have enough power.
- cypress66 4y agoIt's not just the chemistry, but the pack and cable cooling.

Level 2 charging would take about 12 hours. Adding a Level 3 charging ability is non-trivial and doesn't make economic sense with low volume usage.
