Canada to announce all new cars must be zero emissions by 2035::Canada expects to announce this week that all new cars will have to be zero emissions by 2035, a senior government source said, as Ottawa is set to unveil new regulations in the latest example of countries around the world pushing for electrification.
Most people don’t know anything about Canada, even people who live there. Most Canadians live in one of two megacities. They’ve never been to lynn lake, meadow lake, fort McMurray, fort st. John, or pickle lake. The wealth is extracted from these places, but with 0 understanding of what the country is like, particularly in February.
I’d be curious to see electric car range in fort mac’s winter temps.
EV performance in -40C is something nobody talks about but I’m extremely interested in.
There have been lots of videos of Teslas leaving a heated garage then flying around a snowy track in Norway, but that’s much different than getting in a car that’s soaked in the cold all night, driving it to work, then driving home after it sits all day. Or even better, taking that same cold soaked car and driving to the next city 13 hours away with only one or two places to stop along the way.
American here. Even in some northern US states we see - 20F in the winter.
I currently live where winter includes below freezing all the time, with temps approaching 0F frequently. I have friends with EVs, who can’t use their resistive heat (worst way to use battery power) in the winter or they can’t get to work and back, so they conserve power for window defrosting only.
We’re a long way from EV being viable. Wish people would admit that so we can have a proper conversation about it.
Huh, I assumed they pretty much all had heat pumps now. Tesla introduced that several years ago and it made a huge difference, so I’d expect others to have followed.
I live in Northeast US so it doesn’t get that cold, but I can leave my car plugged in and set a schedule so it is all warmed up, when I’m ready to use. No battery. No effect on range
I imagine at -40°C, ICE cars also need heat or a garage
I can only speak for Tesla, but if you have it plugged in overnight, you can schedule the battery and interior to come up to temperature by the time specified - you’ll be leaving on the trip with warm battery, warm interior, and a full charge
Interesting thing about gasoline engines, they become more and less efficient when the temperature drops.
They become more efficient because the air being brought into the engine is denser and cooler which is better, but they become less efficient because rubber parts become stiffer, lubricant becomes harder to move, and overall everything is tougher to deal with.
One result is that if you drive long ranges in -40C, your fuel economy is relatively similar to what it would be in warmer weather. You can blast the heat and your vehicle is toasty warm since it’s just moving waste heat around. I’ve done such drives many times since resources are not where people tend to be.
As you approach -40 you’ll probably want to have your block heater plugged in overnight on a gasoline engine, but generally speaking you can get pretty cold and have the motor turn over just fine. I drove a diesel for a while in the far north and going back to a (really crappy) gas engine was surprising for how easy it was to just get up and go in really cold weather.
