Tesla’s Trip Planner does the math so you don’t have to: enter a destination, and it figures out whether you need to charge, where, and for how long. Here’s what’s actually happening behind the scenes, based on Tesla’s official owner’s manual.
When you enter a destination that requires charging, Trip Planner “selects a route and provides charging times to minimize the amount of time you spend driving and charging,” per the manual. That’s a real optimization, not just a search for the nearest chargers — it balances route and charging time together, which sometimes means skipping a slightly closer Supercharger for one that lets you charge less overall.
To do that, your car estimates the energy you’ll use based on “driving style (predicted speed, etc.) and environmental factors (wind speed and direction, ambient and forecasted temperatures, air density and humidity, etc.),” according to Tesla. In plain terms: how fast you tend to drive and the weather along your route both shape the plan. Tesla also says the car “continuously learns how much energy it uses, improving accuracy over time,” so Trip Planner estimates tend to get more accurate the longer you’ve owned the car.
One detail owners often miss: when Trip Planner is routing you to a Supercharger, your car may use some of its own energy to preheat the battery before you arrive, so it’s at an ideal temperature for fast charging. Tesla says this “reduces charging time” once you’re plugged in — it’s part of why a cold battery charges more slowly than one that’s been preconditioned.
To actually plan a trip, open the Tesla app, go to the location section, tap navigate, and enter your destination, according to Not a Tesla App’s walkthrough of the feature. The app shows your estimated arrival time, current and projected battery percentage, which Superchargers you’ll pass, and how much to charge at each one. From there, you send the plan to your car. It’s worth knowing the feature’s limits, too: Trip Planner doesn’t support adding custom waypoints or extra charging stops beyond what it recommends, and a planned trip can’t be saved — it has to be sent to your car right after you plan it.
The practical takeaway: Trip Planner works best when you let it do the routing rather than second-guessing it. If you want to add a stop it didn’t plan for — a restaurant, a friend’s house — plan that separately, since Trip Planner won’t fold custom waypoints into its charging math.
