Estimate Camp Mode battery use before the overnight stop
Turn arrival charge, temperatures, hours and the next driving leg into a best, expected and conservative battery estimate—with every assumption visible.
Model the overnight stop
Use the usable capacity and road efficiency estimate you trust. If you are unsure, keep the conservative defaults.

The result separates Camp Mode from the next drive and shows a range around the expected outcome.
How the estimate works
The model combines a standby range of 0.18–0.32 kW with a climate-load range based on the temperature gap. It then adds your next driving leg from distance and Wh/km or Wh/mi. Older resistive-heating vehicles receive a conservative multiplier.
It deliberately returns a range. Sun, wind, humidity, battery age, elevation, occupancy and accessories are not fully predictable from a form.
Use official controls
Tesla says Camp Mode maintains cabin temperature and powers USB and low-voltage outlets, but it also changes alarm and Sentry behavior and can stop at low battery. Read the current Camp Mode manual and route with Tesla Trip Planner.
Camp Mode questions
How much battery does Tesla Camp Mode use overnight?
There is no single reliable percentage. Temperature gap, vehicle, battery size, wind, sun, humidity and accessories all matter. This calculator models a low-to-high climate and standby range instead of promising one number.
Can I rely on this estimate instead of Tesla Trip Planner?
No. Use it to test whether your plan has a sensible margin, then check live vehicle data, weather and Tesla Trip Planner. The car is the authoritative source for its current battery state.
Why do I enter battery capacity manually?
Usable capacity varies by vehicle version, market, age and state. A manual estimate is more honest than guessing an exact pack from a model name.
