Electric vehicles bugged
A group of citizen scientists are planting tracking devices in electric vans and cars to measure their performance every
minute of the day, month and year. It is all part of testing how well the EVs go in New Zealand conditions for work and
play, where people drive and charge them, what they cost to run, even how hot their batteries get.
The “EV Black Box” taps into the EV’s instruments and transmits the data via the 3G network to a communal database
operated by Flip the Fleet, a coalition of over 830 EV owners from throughout New Zealand. The devices were developed by Vasily Levshin of Exact
IOT Limited.
“EVs are computers on wheels,” says Mike Sammons, Foodstuffs Sustainability Manager. “We will learn about how well the
electric vans fit our supermarket’s business needs from analysing over 130 data records streaming in from four test vans
every minute.”
The first trials of the system, which are funded from the government’s Low Emission Vehicles Contestable Fund, started
last month in an electric van operated by the New World supermarket in Orewa by Catherine Versalko-West and David West.
“Our electric van is extensively driven every day for online deliveries” says Catherine. “The EV Black Box takes all the
hassle out of uploading driving data each month. It just plugs in and we can now forget about it while it gathers the
numbers to show the capabilities of electric vans to other supermarkets.”
Foodstuffs have deployed 28 electric vans and will have over 50 public charging stations in New World, PAK’n’Save and
Four Square supermarkets throughout the country by the end of 2018.
The EV Black Boxes are also helping Flip the Fleet to test what causes apparent premature battery degradation in some cars. With government’s Curious Minds funding, the Flip the Fleet project will monitor 32 Nissan Leaf electric cars from throughout Otago in the coming year. The researchers and EV
owners mainly want to measure how hot the batteries get during charging because they think a combination of heat and
high charge may make the batteries fade faster.
“It’s a great opportunity for families and businesses to work together with scientists to test new technology” said Dima
Ivanov, co-founder of Flip the Fleet. “They will develop a practical plan to prolong the life of their batteries while still getting the best out of their
EVs.”
Participation in Flip the Fleet is free and all New Zealand’s electric vehicle owners can enrol at www.FlipTheFleet.org
