After more than 100 EV owners agreed to test-drive the system, Moller and Ivanov launched Flip the Fleet to the public last week.
At the beginning of each month, participants receive emails reminding them to upload mileage, charging patterns, the last trip taken and other data gleaned from their vehicle's odometer.
"But these EVs are so smart that they've got a lot of other data stored, such as the battery's health, and you're getting great measures of efficiency of travel."
After putting the data in, users are benchmarked against others and can also see how their vehicle is tracking through time.
"You can see what your mileage is, the dollars you've saved in petrol in maintenance, or what the percentage return on your investment or loan is."
It also gave handy snapshots of their EV's environmental impact, in terms of greenhouse gas emissions saved.
"We are expressing that in the proportion of emissions of a flight from Auckland to London, or how many virtual trees have been planted."
Moller, who was aiming to recruit more than 1000 EV owners, saw the drive as an opportunity to get fine-grained information that could be used to inform people and businesses of the practical benefits of EVs.
"The collective voice of early adopters will be heard by more people, but more generally, people make decisions about their next vehicle purchase based on a huge variety of criteria, following information and testimony of people they trust.
"This project is trying to empower the advocacy of an army of citizen scientists to help them make a better case for EVs when discussing them over the dinner table, or over than back fence with their neighbour, or with their business leaders in staff meetings.
"There is also great value in having real data from New Zealand and in our local neighbourhood."
