5. Only recent news is allowed.


Posts must be news from the most recent 30 days.


6. All posts must be news articles.


No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.


7. No duplicate posts.


If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.

How is Norway bad for EVs then

Batteries don’t like the cold.

They don't like charging in the cold but they'll dissipate just fine

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

It is a plroblem for people who want to trust that their vehicle will work if it's 5° out and the power's out, and your vehicle has been sitting in the child all night. The average temperature is irrelevant in that case - you must have a well-insulated battery, and power to heat it.

The fact is, in the north, the failure case is pretty bad. There's nobody who can just bring you a can of gas, there's no chance to recharge it without heating it first, and in order to charge it, you'll need to tow it. And forgetting to charge realistically becomes a life-and-death situation at worst, and a major hassle at best. To be fair, forgetting to get gas has always been a serious issue in the cold, but the current situation regarding batteries exacerbates that.

The two main things that are needed to fix this are:

  • batteries that don't cease functioning in the cold
  • technically-sound, government-enforced interchange standards
