Flip the Fleet: a Citizen Science Approach to Accelerating Uptake of Low Emission Vehicles in New Zealand.
Encouraging uptake of Low Emission Vehicles (LEVs) in New Zealand requires extraordinary efforts to overcome barriers of misconceptions amongst potential purchasers, the absence of strong financial subsidies and regulatory incentives to buy LEVs, and sparse rapid charging infrastructure. The Flip the Fleet project (FtF) takes a ‘citizen science’ approach to better inform the public and businesses of LEV practicality…….
Estimation of the fossil fuel savings by Low Emission Vehicles (LEVs) requires an estimate of the fuel consumption of ‘equivalent’ internal combustion engine vehicles (ICVs) that have been displaced. Therefore we first constructed a statistical model of standardised vehicle test ‘driving cycle’ measures of fuel consumption of 90 conventional (ICVs) for ‘urban’, ‘ex-urban’ and ‘combined’ driving conditions in New Zealand. The model …….
Rapid chargers for battery electric vehicles in New Zealand: current use, access and location preferences
Rapid chargers are now installed at many strategic positions to enable long-distance travel through much of New Zealand, even by short-range Battery Electric Vehicles (BEVs). However, our survey of 108 BEV owners found that they are required to wait an average of 10 minutes for their turn to charge in around 14% of visits to a rapid charger station. The chargers are not functioning on around 4% of the visits and blocked by an internal combustion vehicle on 2% of visits…..
Analysis of 1,382 measures of battery State of Health (SoH) from 283 Nissan Leafs (“Leaf/s”), manufactured between 2011 and 2017, has detected a faster rate of decline in this measure of energy-holding capacity for 30 kWh variants. At two years of age, the mean rate of decline of SoH of 30 kWh Leafs was 9.9% per annum (95% uncertainty interval of 8.7% to 11.1%; n=82). This was around three times the rate of decline of 24 kWh Leafs which at two years averaged 3.1% per annum (95% uncertainty interval of 2.9% to 3.3%; n=201)…
