Live Lab #6 (April)





As you can see from the image above, the car averaged 13.7kWh/100km in April. This is a reasonable improvement over the 14.9kWh/100km observed in March. The improvement is most likely down to a change in weather.....warmer air temperatures make the batteries more efficient. 


This works out at a cost of €1.73 per 100km (charging at home). By way of comparison, a reasonably good efficiency in a petrol car would get about 5l/100km. At current petrol prices around Galway (€1.46-ish per litre), this equates to about €7.30 per 100km. Over the distance travelled in April, such a petrol car would have cost about €45 in fuel.

Would you rather pay €45 or €11 for your entire monthly commute?

Interesting to note that over the past month or so, petrol prices have risen by about 10cent per litre. This can have a big effect over a longer period of time. Fossil fuel is not only running out, its price can fluctuate wildly. In the 18 months or so that I've had my LEAF, the price I pay for electricity has barely changed at all. So, at a time of year when the EV is getting more efficient to run due to warmer weather, and fossil fuel prices are rising, the overall savings are getting even better.


*A note on the stated CO2 Savings shown above:
