How Tesla Superchargers Work
Tesla Superchargers work by converting AC power from the grid to DC power directly suitable for charging Tesla vehicles. This process bypasses the onboard charger in the vehicle, allowing for faster charging speeds. Superchargers use an electrical cabinet containing a stack of vehicle rectifiers that operate in parallel to convert AC power to 400V DC power. Each cabinet can supply power to two charging stalls, and if one vehicle is plugged in, it can pull maximum power. If two vehicles are plugged in, the first vehicle gets most of the power, and the second vehicle gets the remaining power.
Tesla has redesigned their vehicle rectifiers multiple times to improve efficiency, power density, and cost. Superchargers are available in different versions, with the latest being V4, which uses 800V charging to charge vehicles with 800V class battery packs at faster speeds.
Tesla vehicles can charge at up to 200 miles of range in 15 minutes, depending on the model. Charging speeds can vary based on the battery's current charge level; the lower the charge, the faster it will charge
reading that - to me -
it says thatt the onboard charger is limiting factor for speed of power transfer - thus you have a single entry point when plugged into home plug.
at the supercharger station, they go around the charger and power directlyand they can do that with multiple rectifiers - eliminating a bottleneck
