What factors are considered when calculating an electric car's range in city traffic? How do things like battery capacity, driving style, temperature, and traffic volume actually affect the estimated mileage? Are there reliable models that dynamically factor in these variables, or do most people just rely on static figures? Which approaches do you find realistic, and what testing methods do you use to verify real-world performance?
How does the range calculation work for electric cars in city traffic?

When testing the Tesla Model 3 in Berlin’s inner city, I noticed that range depends heavily on three dynamic factors: driving style (how often and how aggressively you accelerate), outside temperature, and real traffic conditions (stop-and-go segments). A practical approach is to monitor the car’s built-in energy consumption display and log the actual kilometers driven and average consumption (kWh/100 km) after each full charge. You can then input the data into a simple Excel spreadsheet and use linear regression to model the relationship between consumption, temperature (°C), and average stops per kilometer. This gives you a dynamic estimation model that’s far more accurate than the manufacturer’s static figures and instantly adapts to your personal driving habits. If you don’t want to track the data yourself, apps like “A Better Route Planner” already factor in temperature and traffic data to provide estimated consumption for any planned route.
