Most Supercharger stops don’t require any thought beyond plugging in. But at a busy station, a few habits make the difference between an easy stop and a line of cars waiting for a stall, and between a free charge and an unexpected fee.
Charge to what you need, not to 100%
Tesla’s own guidance is direct about this: the company wants drivers to “charge only as much as is needed for their trip, rather than all the way to 100%” when a station is busy. Charging speed also slows dramatically past 80%, so topping off to 100% at a crowded stop mostly means you sit longer for a small amount of extra range, while everyone behind you waits.
Move your car when you’re done
Tesla compares an occupied, fully-charged stall to a car left parked at a gas pump: something you’d never do, and something the Supercharger network is designed to discourage. Congestion fees kick in when a station is busy and your car has either hit 80% or finished its charging session, and Tesla gives you a five-minute grace period to unplug and pull away before the per-minute fee starts. Rates vary by location, but the fee only applies at stations that are already crowded, so an empty station won’t charge it even if you linger.
Park to share power, not to block it
Many Supercharger stalls share power in pairs, which means the car you park next to can affect your own charging speed. According to InsideEVs, parking next to a stall that’s already occupied and charging, rather than starting a new pair, helps balance the load between both cars instead of splitting a fresh pair’s shared power unevenly. It’s a small choice, but at a full station it adds up.
Let the app do the watching
You don’t need to sit in the car or hover nearby to avoid a fee. The Tesla app sends a notification as your charge nears completion and again once it’s done, so you can grab coffee or use the restroom and still get back before the grace period runs out. At a quiet station off-peak, none of this matters much. At a packed one on a holiday weekend, it’s the difference between a five-minute stop for the next driver and a ten-minute wait.
