Tesla Inc. is updating its charging network to halve typical wait times as the Model 3 fleet grows larger and rivals like Porsche ready their own powerful infrastructure.

After doubling power at Tesla’s stations and vehicles preheating batteries ahead of arriving at a plug, charging times will drop to around 15 minutes, the electric-car leader said on its blog. The rollout of the V3 Supercharging network will take until the end of the year and allow twice as many cars each day to charge.
