EV Project Tells Us How Drivers Use Electric Cars

Just how do electric car owners use their cars? It’s the question everyone is trying to answer, as it could shape how electric cars of the future are developed.

Virtually every manufacturer with an electric car runs its own field trials or keeps data on its users’ driving habits, but the EV Project aggregates data from different makes and models, and thousands of owners, who use the charging stations that are monitored by the program.

Most recently, the EV Project has revealed its fourth quarter 2012 results, and with over 60 million miles logged it’s building an increasingly thorough picture to help answer that question.

Most of the survey’s data concentrates on Chevrolet Volts and Nissan Leafs–as the two most prolific electric vehicles on sale. However, Smart Electric Drive models also feature.

Volt versus Leaf

It’s comparison between the Volt and Leaf that proves most interesting, though.

The data fluctuates from quarter to quarter, but by the end of 2012, Volt owners charged more at home than their Leaf counterparts, at 81 to 76 percent respectively. Overall, the Project suggests that around 80 percent of charging is done at home.

At the same time, Volt drivers also charge more frequently–an average of 1.4 times per day compared to 1.1 per day for the Leaf.

This is interesting, not for its frequency (perhaps obvious given the Volt’s shorter electric range), but the fact that Volt drivers must consciously be charging so they can drive using the car’s electric power alone–rather than doing any extra distance on the gasoline range-extender.

At around 40 miles, Volt drivers actually travel around ten miles further than Leaf drivers per day, though drivers of each tend to recharge after a similar number of miles, on average–around 30 miles. This again suggests that Volt drivers really are making the most of the car’s electric range, backed up by previous data showing around two thirds of all Volt miles are on electricity.
