Understanding Your Calculation Results
When you use our EV charging calculator, you receive detailed results that help you plan your charging strategy effectively. Here’s what each output means and how it’s calculated:
1. Energy Required (kWh)
What it shows: The total electrical energy needed to charge your battery from current level to target level.
How to calculate EV energy required:
- Formula: Energy Required = (Target % – Current %) ÷ 100 × Battery Capacity
- Step 1: Calculate charge difference (Target % – Current %)
- Step 2: Convert to decimal by dividing by 100
- Step 3: Multiply by battery capacity in kWh
- Example: Tata Nexon EV (20% to 80%) = (80-20) ÷ 100 × 40.5 kWh = 24.3 kWh
- This represents the actual energy stored in the battery, not accounting for charging losses
2. Charging Time (Hours)
What it shows: The time required to complete charging based on your selected charging method.
How to calculate EV charging time:
- Basic Formula: Time = Energy Required ÷ (Charging Power × Efficiency)
- Step 1: Determine charging power (3.3kW home, 7.4kW public AC, 25kW DC fast, 50kW+ ultra fast)
- Step 2: Apply efficiency rate – Home (85%), Public AC (88%), DC Fast (90%), Ultra Fast (92%)
- Step 3: Divide energy required by (power × efficiency)
- Step 4: For 80%+ charging, apply 50% speed reduction for battery protection
- Example: 24.3 kWh ÷ (7.4 kW × 0.88) = 3.7 hours for Public AC charging
3. Charging Cost (₹)
What it shows: The total electricity cost for your charging session.
How it’s calculated:
- Cost = Energy Required × Electricity Rate × Location Multiplier
- Home charging uses your input rate directly
- Public charging applies 1.5x multiplier to account for service charges and taxes
- Example: 24.3 kWh × ₹8/kWh × 1.5 = ₹291 for public charging
4. Range Added (km)
What it shows: Additional driving distance gained from the charging session.
How it’s calculated:
- Range Added = (Charge Added % ÷ 100) × Vehicle’s ARAI Range
- Based on manufacturer’s certified range under standard test conditions
- Real-world range may vary by ±20% depending on driving conditions, weather, and usage patterns
- Example: 60% charge added × 437 km range = 262 km additional range
Advanced Calculation Methodology
Charging Curve Implementation
Our calculator incorporates real-world charging behavior through advanced algorithms:
- 0-80% Charging: Full power delivery with standard efficiency rates
- 80-100% Charging: Reduced power (50% of rated) to protect battery and ensure safety
- Temperature Compensation: Assumes optimal charging conditions (15-35°C)
- Battery Management System (BMS) Overhead: Included in efficiency calculations
Cost Analysis Calculations
Cost per Kilometer
How to calculate EV cost per km:
- Formula: Cost per km = (Battery Capacity ÷ ARAI Range) × Electricity Rate
- Step 1: Divide battery capacity (kWh) by vehicle range (km)
- Step 2: Multiply result by your electricity rate (₹/kWh)
- Example: Tata Nexon EV = (40.5 kWh ÷ 437 km) × ₹8/kWh = ₹0.74 per km
- This gives you the energy cost for each kilometer of driving, helping compare with petrol/diesel vehicles
Monthly Cost Estimation
Formula: Monthly Cost = Monthly Distance × Cost per km
Based on your input monthly driving distance, this calculates your expected electricity bill for EV charging.
Annual Savings Calculation
Our calculator compares EV costs with equivalent conventional vehicles:
- 2-Wheeler Comparison: vs 45 kmpl petrol scooter at ₹105/liter
- 3-Wheeler Comparison: vs 25 kmpl CNG auto at ₹95/kg
- 4-Wheeler Comparison: vs 15 kmpl petrol/diesel car at ₹95/liter
Formula: Annual Savings = (Fuel Cost per Year) – (Electricity Cost per Year)
Efficiency Rating (km/kWh)
Formula: Efficiency = ARAI Range ÷ Battery Capacity
This metric helps compare energy efficiency across different EV models. Higher values indicate better efficiency.
