Sinopec, China’s biggest fuel retailer, just gutted one of its Shanghai gas stations and swapped the pumps for BYD’s 1,500 kW flash chargers. How an old gas station pulls off megawatt chargingA 1,500 kW charger drawing straight from the grid would need a substation-grade connection. So an old fuel station can do megawatt charging without a grid rebuild. The reason megawatt charging feels impossibly expensive here is that everyone assumes you have to rebuild the grid connection to deliver it. Put a battery between the grid and the car, pull 100 kW in, push 1,500 kW out.
