Calculate accurate charging times for your Tesla based on battery level, charger type, and model specifications. Plan your charging sessions with precise time estimates for home and public charging.
This page includes an interactive time calculator, charging speed comparisons, usage guides, charging optimization tips, and answers to frequently asked charging time questions.
Enter your Tesla details and click "Calculate Time" to see your estimated charging time.
Follow these simple steps to calculate your Tesla charging time accurately
Choose your Tesla model or enter custom battery capacity
Adjust starting and target battery percentages
Select your charger type and power level
Get your estimated charging time and speed
Charging is fastest between 10-50% battery level. Speed decreases significantly after 80%.
Cold batteries charge slower. Precondition your Tesla while plugged in for faster charging.
Level 2 chargers are perfect for overnight charging. Use Superchargers for quick top-ups.
Monitor charging progress remotely and get notifications when charging is complete.
Understanding charging speeds and time estimates for different scenarios
Level 1 & Level 2

Most likely using Level 1 (120V) instead of Level 2 (240V). A 240V outlet with Tesla Wall Connector charges 8x faster than a standard outlet.
Arrive with low battery (10-20%), precondition while driving to Supercharger, avoid charging past 80% unless needed.
No. Tesla recommends daily charging to 80-90%. Only charge to 100% before long trips for optimal battery health.
Daily charging is fine and recommended. Tesla batteries are designed for frequent charging. Avoid dropping below 20% regularly.
Use Tesla app to schedule charging during off-peak hours for lower electricity rates and reduced grid demand.
Warm up battery while plugged in during winter. Use "Navigate to Supercharger" to automatically precondition.
Track charging patterns in Tesla app to optimize your daily routine and identify the best charging times.
Understanding the science behind Tesla charging calculations and what affects your charging speed
Where Energy Needed = Battery Capacity × (Target % - Current %)
Total energy storage in kWh (e.g., Model 3: 82 kWh)
Target % minus current % (e.g., 80% - 20% = 60%)
Charger output in kW (e.g., Supercharger: 150kW avg)
With a Level 2 charger (240V), most Teslas can charge overnight in 6-12 hours. A standard 120V outlet takes much longer, typically 24-40 hours for a full charge from empty.
Tesla uses a charging curve that reduces power as the battery fills to protect battery health. Charging from 80-100% takes almost as long as charging from 20-80%.
Tesla Superchargers can add 200+ miles of range in just 15 minutes under optimal conditions. Peak charging speeds reach up to 250kW, but average around 150kW due to the charging curve.
Yes, cold temperatures can significantly slow charging speeds. Preconditioning your battery while plugged in helps maintain optimal charging speeds in cold weather.
Our estimates use official Tesla specifications and charging curves. Actual times may vary based on temperature conditions, battery age, charger availability, and specific charging scenarios. This tool is not affiliated with Tesla, Inc.
