When the now popular Tesla Model S electric car was first introduced in 2012, there were no Superchargers available. Today, there are 25,000 Tesla Superchargers around the world, and with the Model S Plaid adopting a new powertrain, Tesla was able to re-design the battery to take advantage of the third-gen 250-kW Supercharger. Despite Tesla still using the 18650 form-factor cylindrical battery cells, these now have improved chemistry to deliver higher performance and durability. (This is the fourth major chemistry improvement since the first Model S.) With it newest 100-kWh battery pack, Tesla claims the Plaid can recover 187 miles of driving range in 15 minutes of charging at a V3 Supercharger. But just how realistic is that claim in practice?

First, a little background on charging an EV in general. Many factors are in play to determine the charging performance, from ambient temperature to battery temperature to state of charge to charging station type. As a result, charging rates do vary in practice. Lithium-ion batteries have a certain working temperature range, typically 40-130 degrees Fahrenheit, and the higher end of the range is typically conducive to rapid charging. For an electric car that has sat unplugged overnight or in cold weather, charging time is prolonged. In a Tesla, when a driver puts a Supercharger into the navigation as its destination, the car preconditions the battery pack for rapid charging before it reaches the plug. This helps to deliver a more consistent rapid-charging experience and eases congestion at charging sites.
