For cold climates, ev's have a built block heater, and it takes power.

The problem is refueling, a sitting ev needs to power its own heater running down the battery, and to make it worse, batteries already have lower power in winter.

Thus the cars are all waiting to refuel and ran out of power.

A Hybrid is a better option until refueling EV's are not an issue.

It's a charger issue, did any one read the damn article?

Am I blind or is there only one sentence that could possibly imply that?

> He was forced to hire a flatbed tow truck to haul the vehicle to a working charging station.

The rest of the article is talking about other issues.

My sister lives in Chicago and her ICE car also won't start due to the extreme low temperatures. The Canadians solved this problem by having resistive heat elements installed in their engine, I think EVs probably need the same.

Even in Canada the gas pumps froze over and ICE cars are unable to fill gas.

Same in Illinois but the article doesn't mention it https://www.wcia.com/news/local-news/cold-weather-causes-fro...

The article says nothing about the charger. (Maybe you can quote it?)

In general, Teslas won't supercharge until the battery reaches a specific temperature. It's well-known that a Tesla will sit at a Supercharger and heat the battery until it's warm enough to charge, sometimes for 20+ minutes.

As far as why this incident happened, I have no idea, and nor does the article speculate.

Tesla replaced the resistive heaters in their vehicles with a heat pump. When it's super cold they run (essentially) DC power through their AC motors so the motors don't spin, they just heat up. The heat pumps then scavenge heat from the motors.

It's resistive heat, but not a resistive heat element.

Block heaters are extremely common in colder climates - upper midwest of the USA, Alaska, central Canada, etc. You can identify them when you see a vehicle with an electrical cord stub dangling just below the front bumper or in front of the grille. In fact, during my road trips through Alaska and Canada I frequently saw power outlets in front of parking stalls at hotels so that guests could plug in the heaters overnight.

A friend hypothesized that a lot of Tesla drivers charge the same way they refilled their gas cars, by waiting until the last minute and supercharging back up to "full". This doesn't work when it's so cold so people need to learn to charge a little at a time.

From personal experience there is a similarity with people who charge their phone when they can and people who charge it when it is about to die. My SO and I are on opposite sides of this spectrum and the dichotomy is quite stark. This also applies to charging vehicles as I take every opportunity to top off and she waits until it's about to hit 0%.

I learned to drive on a 1976 VW Rabbit diesel. We had a block heater for it, and in the winter, we had to plug it in to warm it up. You'd think there'd be some way to do that for EVs.

There is.

*Not a "dedicated" resistive heating element (obviously the motor doubles as a resistive heating element). Also below a certain ambient temperature, heat pumps with heating elements run at approximate the same efficiency as the heating element itself. None of this is bad design though, if the ambient temperature is a bit higher than the minimum temperature, you would then get additional COP from the heat pump.

I charge my phone while I sleep.

If I owned an EV, I would charge it like I charge my phone.
