Canada just announced a ban on internal combustion engines

Canada announced this week that it would ban the sale of new internal combustion engine (ICE) cars and light-duty trucks by 2035 as part of its efforts to fight climate change, a report from Reuters telling.

Canada joins a growing list of countries banning fuel-powered vehicles, Britain has said it will ban ICE vehicles by 2030, and Norway – another country with extremely cold winters – has announced that It will do the same only in early 2025.

Although phasing out ICE vehicles is a necessity, along with other measures needed to mitigate the effects of climate change, a major obstacle remains in cold-weather countries: extreme climates reduce the range and electric Extends the charging time of vehicles.

battery in cold

Cold climates can cut EV range drastically. A 2019 report by AAA states that cold weather can reduce the range of electric vehicles by up to 40 percent.

In a world where electric vehicle (EV) ranges are still far from allowing the same access as ICE vehicles, the effects of low temperatures could make the transition to electric vehicles difficult.

AAA study (link opens a PDF) found that at 20 °F (-6 °C)The average EV range dropped by 12 percent when the car’s heater was not turned on. However, turning on the heater while driving reduced the range by 41 per cent.

The reason behind this is that EV batteries use energy to heat the passenger cabin while preventing coolant from freezing in cold weather.

slow charge time

Whereas internal combustion engines generate their own heat while operating, EVs need to generate heat elsewhere in colder temperatures, usually by using a battery thermal management system.

Another problem is the issue of charge time in extreme climates. A 2018 study explains how Cold temperatures affect the electrochemical reactions within the lithium-ion batteries used in cars, forcing the EV battery management system to limit charging rates to avoid damage to the battery.

That study found that, when an EV battery was charged to 77 degrees Fahrenheit (25 degrees Celsius), a DC fast charger could charge a battery to 80 percent in 30 minutes. However, at 32 °F (0 °C), the battery had a 36 percent lower charge after the same time period.

Tips for EV Owners in Cold Countries

While the impact of cold weather on electric vehicles is hindering widespread adoption in regions with extreme climates, the new announcement by Canada and several other countries means people will eventually have no choice.

Though innovations will emerge undeniably – Audi For example, the e-tron already includes a heat pump, heated seats for more efficient heating, and a cold-weather option that preheats the car while it’s charging – for EV owners in cold regions. A little extra planning may always be necessary. Climate

As Anna Stephanopoulou, director of the University of Michigan’s Energy Institute, pointed out, wiredEV owners in cold countries should try not to let their car battery drop below 20 percent, as the initial charge will help prevent charge times from slowing down.

Drive Electric Vermont explains that preheating the car’s interior before departure will release more energy for battery charge. Similarly, driving a little slower can increase range by reducing air resistance.

Hybrid and hydrogen as alternatives?

For drivers who want to be more environmentally friendly without extra planning and thought, another option is self-charging electric-ICE hybrid vehicles, which use their internal combustion engines to get going..

Hydrogen vehicles also have the potential to perform better in cold weather. For example, Toyota recently touted the performance of its fuel cell vehicles in colder climates than EVs, saying that neither range nor performance is affected in colder temperatures.

While there’s no stopping the sustainable transportation drive for years to come, a little extra planning and foresight will help vehicle owners prepare for the transition, either to electric or fuel cell vehicles.
