## How it calculates

The conversion between kWh/100 km and km/kWh is based on the following formulas: 
1. To convert from kWh/100 km to km/kWh:  
   km/kWh = 100 ÷ (kWh/100 km) 
2. To convert from km/kWh to kWh/100 km:  
   kWh/100 km = 100 ÷ (km/kWh) 
In these formulas, 'kWh' represents kilowatt-hours, which is a unit of energy, and 'km' represents kilometers, a unit of distance. The division by 100 is necessary because the first measurement (kWh/100 km) expresses energy consumption per 100 kilometers, while the second (km/kWh) expresses distance traveled per kilowatt-hour of energy consumed. This mathematical relationship highlights the inverse nature of the two measurements; as energy consumption increases, the distance traveled per unit of energy decreases, and vice versa.

## Who should use this

Electric vehicle manufacturers assessing energy efficiency standards. Fleet managers optimizing electric vehicle usage for cost savings. Researchers studying the environmental impact of electric vehicle energy consumption. Automotive engineers designing more efficient electric drivetrains.

## Worked examples

Example 1: A driver notes that their electric vehicle consumes 20 kWh per 100 km. To convert this to km per kWh, use the formula: km/kWh = 100 ÷ (20) = 5. This means the vehicle can travel 5 km for every kWh consumed.

Example 2: An electric vehicle is reported to travel 4.5 km per kWh. To find its energy consumption in kWh per 100 km, apply the formula: kWh/100 km = 100 ÷ (4.5) = 22.22. Thus, the vehicle consumes approximately 22.22 kWh to travel 100 km.

Example 3: A fleet manager has a vehicle that consumes 15 kWh per 100 km. To determine how far it can go per kWh, calculate: km/kWh = 100 ÷ (15) = 6.67. Therefore, this electric vehicle can travel about 6.67 km for each kWh of energy used.

## Limitations

This tool assumes that the input values are accurate and that the electric vehicle is operating under standard conditions. Results may be less accurate if the vehicle experiences varying driving conditions, such as steep inclines or heavy traffic, which can affect energy consumption. Additionally, the tool does not account for auxiliary energy use, such as heating or air conditioning, which can alter efficiency. Precision may be limited by rounding during calculations. Finally, the tool does not consider battery degradation over time, which can impact real-world performance.

## FAQs

**Q:** How does temperature affect electric vehicle efficiency calculations?


**A:** Temperature can significantly impact battery performance and energy consumption. Cold temperatures may reduce range and efficiency, while hot conditions can lead to increased energy use for cooling systems.


**Q:** What is the significance of using kWh per 100 km versus km per kWh?


**A:** Using kWh per 100 km provides insight into energy consumption, which is useful for understanding costs, while km per kWh indicates efficiency, which helps evaluate vehicle performance and sustainability.


**Q:** Can this tool be used for hybrid vehicles?


**A:** While primarily designed for electric vehicles, the conversion can also apply to hybrid vehicles for assessing their electric mode efficiency, given accurate energy consumption data.


**Q:** Are there specific standards for measuring kWh per 100 km?


**A:** Yes, various organizations provide standards for measuring energy consumption in electric vehicles, such as the EPA in the United States, which helps ensure consistent and comparable efficiency ratings.
