Something like the XPENG G6 comes to mind. 800V platform, so very fast charging speeds 80kWh battery with realistic range of 450 km On a ~680km trip you can make 2 short charging stops (13 minutes each) and arrive with 60% battery (>250km range). Although I’d challenge the assumption about having to have 250km left at your destination. Just plug it into an AC charger or even just a standard AC house plug at 2,3 kW. Idle time is free charging time
