    How are most countries more suitable for EVs than Norway? Norway’s hydro power and smaller size is pretty great for EVs.

      The size of the country isn’t particularly relevant. How many Australians for example regularly cross the desert? What’s relevant is how far individual people commute and that tends to be a function of things like adoption of Work From Home policies and population density.

      For example the UK is quite good for electric vehicles because the population is very dense (especially in London where the population is extremely dense).

              Most lithium ion batteries take permanent damage if charged below 32°f, and if they are used below 15.

              Sodium ion batteries w/prussian blue are a major breakthrough. Considerably lower cost, no bad chemicals or rare elements, comparable energy density to Lion, prospects for better energy density in the future, and nob-damaging use/charge in cold temperatures. Neat stuff.

                They don’t want to change way before 32, they heat the packs to fast charge. But 15 degrees is really uncommon as a consistent temperature in most populated areas and that’s also why you insulate the pack to keep them from getting excessively cold.

                I personally think LiFePo cells are currently the most proven opinion. Only downside is density but 300mi is fine idk why more is needed.

                  Yeah, they heat the packs to get around it. And all of that is waste energy.

                  But in winter in Canada, and many parts of the northern US, under 30 degrees average is pretty common during winter. …and the last thing you want is a vehicle that’s great when things are fine, but just won’t work when things are at their worst.

                  Fortunately, the temperature issue is a problem that has been solved, and is being brought to market.

                    It’s not really a problem unless you don’t have the ability to drive the EV. Most people aren’t driving long distances so just heat the battery and lose efficiency. People use more energy just heating the interior for themselves than the battery
