Formula Used in Tesla Charge Calculator
This tool uses real EV energy and cost formulas.
1. Energy Needed Formula
The energy required depends on battery capacity and charge difference.
Formula:
E=C×100(T−A)
Where:
- E = Energy needed (kWh)
- C = Battery capacity (kWh)
- T = Target charge (%)
- A = Current charge (%)
Example:
| Battery Capacity | Current % | Target % | Energy Needed |
|---|---|---|---|
| 75 kWh | 20% | 80% | 45 kWh |
2. Charging Cost Formula
Electricity cost is calculated using energy consumption.
Formula:
Cost=E×PricekWh
Where:
- E = Energy needed
- PriceₖWh = Electricity cost per unit
Example:
| Energy Needed | Cost per kWh | Total Cost |
|---|---|---|
| 45 kWh | $0.15 | $6.75 |
3. Driving Range Formula
Range depends on energy and efficiency.
Formula:
R=E×Efficiency
Where:
- R = Range (km)
- E = Energy (kWh)
- Efficiency = km per kWh
Example:
| Energy | Efficiency | Range |
|---|---|---|
| 45 kWh | 5 km/kWh | 225 km |
Tesla Charge Calculation Table Example
| Battery (kWh) | Current % | Target % | Energy (kWh) | Cost ($0.15/kWh) | Range (km) |
|---|---|---|---|---|---|
| 60 | 20% | 80% | 36 | 5.4 | 180 |
| 75 | 30% | 90% | 45 | 6.75 | 225 |
| 100 | 10% | 80% | 70 | 10.5 | 350 |
