They and a lot of EV still use decades old Li-ion battery tech made for laptops! They went with what they had at hand, but better options are coming automakers and others are betting the farm on dozens of new battery types.
That’s a lot closer. Beowulf’s tribe were our norhern enemies and at times friends, even a marriage between royals. My tribe’s first king, Finn, is mentioned in Beowulf. My ancestors eventually defeated them. Just like they held back the romans, the spanish, napoleon and for a long time the dutch. All that’s left is a province in NL and some areas in north germany and denmark (which used to be Frisia). One of those small cultures that feel threatened by progress as you brought up a few times.

better options? That was a new Tesla with the newest battery pack they had....and it was still DOA at 17F, i can't imagine what they are in Chi town....the neighbor i mentioned to me last night,he wants his money back, and he will never buy a EV again.....untill tech get a heck of a lot better, and infrastructure get better, think i stick with my gas vehicle
Yet Norway has highest EV share (90% of new cars), before Sweden, Iceland (and NL). Most popular model in those countries: Tesla Model Y. The winters you described in an earlier post is what I miss, how my winters were a few decades ago, when it would not just occasionally freeze at night but remain below freezing point by day and people ended up ice skating on lakes and canals. In scandinavia, lowest temp this winter around -40C/F. Not quite northpole but still.
It does appear like a Ray Kurzweil singularity, but it might not be as "transformative" as people think. We'll be lucky to get way by the skin of our teeth over climate change. The smell of money in solar, batteries and EVs on the new breeze blowing through the environmental community is refreshing and invigorating too I might add. Green is also the color of money (American), technology and greed got us into this shit and hopefully it will not just get us out, but to a better place. I advocate solving climate change using science, technology, capitalism and good old-fashioned greed.
The front trunk of an EV. A very small propane heater can heat the battery cooling system that uses liquid coolant and a radiator, it can be vented along addon steel channels along the bottom of the battery bank too to get all the heat out of it and warm up the pack. Likewise, an EV can use an electric heater to heat the battery pack using a pump and the same power supply already in place for ICE car block heaters. These can be retrofitted to EVs as kits and expect things like that to hit the market, if cold weather is an issue in some places.
i'm kinda like you....hybrid EV would work better. I think toyota is working on a better version of that now, they won't go full electric for the time being....
if cold weather is an issue in some places? lets try 3/4 of the US and Canada.....that where this last vortex hit...js....and it's going into the NE and Upper NE now i believe...better get your snow shovel out..it's gonna be a doosey...
North America is not the whole world and climate change is a global issue. There might be better batteries and heaters because few will buy an EV if it leaves you stranded at -35C in the middle of nowhere Manitoba!
Another way of looking at is a better battery that takes up less space and weighs less. Put a 10 or15 HP gas or propane engine/generator in a hybrid and it can generate from 10 to 20 kilowatts to charge the battery and it can warm the battery pack in winter, when it would be used, say its the size of a big bread box. The car can be plugged in and runs 90% of the time on plug in power from home generated using rooftop solar. Propane might be best, if the fuel is gonna be in the tank a long time and a barbeque tank should last a very long time, just change it out at the gas station or convenience store.
I drove big rigs that have a tiny diesel powered heating unit that circulates the antifreeze through the system keeping both the engine and the cab of the truck plenty warm enough at -40 that the engine doesn't need to be left running all night. Much quieter too so sleeping in the truck is much nicer and it generates power to keep the battery topped up and able to run a fridge, TV, fans etc.
Something small for an EV battery you might just get 10 kilowatts of charging power at 20% efficiency, but the main purpose of the gizmo is to heat the battery so even exhaust gas can be used to make it super-efficient. Propane might be best if it isn't used for a year or two except for test starts etc and a barbeque gas bottle could last a long time, and everything might be automated somewhat. A plug-in battery pack heater would go with it. It might be made as a kit and aftermarket thing it just needs to heat and circulate the power pack coolant, so you can tap into the cooling system at the radiator.I drove big rigs that have a tiny diesel powered heating unit that circulates the antifreeze through the system keeping both the engine and the cab of the truck plenty warm enough at -40 that the engine doesn't need to be left running all night.

Pretty sure similar units can run on other fuels as well.
Stellantis making the Ram 1500 Ramcharger an EV with on-board gasoline generator is an intelligent way to get more people into EV's. 145 miles powered on batteries alone, and 690 miles with full battery and full tank of gas. The generator is still going to require maintenance like any other engine, but many drivers will be able to go a long time without using the generator to charge the battery.
