temperatures hovering around +5…-15 °C

We’ve just come off a cold streak like this and I have to say it was no big deal.

Obviously I don’t know of there are long term effects on the battery but

most/all EVs have active thermal management now so will maintain a healthy temperate while in use
my decision point on technology maturity was when they started using heat pumps rather than resistive heat. That’s still too rare but makes a huge impact on cold weather range

The only good things about NMC cells is the energy density and the ability to pull a decent power during acceleration.

When it comes to temporaries, they are surprisingly picky. Too hot or cold, and they wear out quickly. If you push beyond that, you’ll lose range instantly. That’s why a heat pump is such a great thing to have.

Also, the state of charge matters to longevity. If you use the wrong percentages frequently, you’ll start losing capacity sooner or later. Even if you treat the battery perfectly, it’s still going to wear out like the tires do, but this thing costs as much as an engine.

I’m really looking forward to seeing all the other battery chemistries take their share of the market.
