A recent report from Canada’s Department of Natural Resources says it is still “too early” to fully evaluate the reliability of electric vehicles (EVs) in Canadian winters despite comprehensive research spanning six years at an investment of $76.1 million.
The federal government allocated up to $76 million in funding under Budgets 2016 and 2017 for the Electric Vehicle Infrastructure Demonstration Program (EVID), which says it aimed to “accelerate the market entry of next generation clean energy infrastructure, by supporting demonstration projects of innovative EV charging and hydrogen refuelling technologies, in order to lead to an increased uptake of ZEVs.”
The Department of Natural Resources funded various projects under the program, including the operation of winter charging stations in Yukon and electric buses in Brampton, Ont. The report acknowledges the availability of zero-emission vehicle technologies but points out existing technical and non-technical barriers, particularly related to charging efficiency in cold weather.
Though the research has been extensive, the department said that conclusive results are yet to be obtained.
“Unlike a gas car, where the heat is free, coming from the engine, an EV has to produce cabin heat and manage an optimal battery temperature with energy that comes from the battery, in turn reducing range,” stated Consumer Reports’ “Tests Show Electric Car Range Can Fall Far Short of Claims.”
The report warns of potential unintended outcomes of the measures, including impacts on electrical grid distribution networks due to uncontrolled charging and environmental concerns related to battery component mining.
There are also social implications, the report notes, such as the potential pollution affecting nearby indigenous communities involved in mining activities for EV battery components. Additionally, the report mentions concerns about carbon emissions generated during the production of electric vehicles.
“The extremes of temperature required for military operations is probably the biggest technological challenge for hybrid and electric vehicles,” said the 2019 report.
“The issue of reduced battery capacity at low temperatures is well known.”
