Usually such reports will be for the red-headed step children of the EV world (read: anything other than a Tesla) but, no! These were quite often even Teslas! .

What is going on? Well, batteries don't like the cold. That's probably not a big surprise to many people. When does the 12V battery in your car die? On a lazy Saturday in late May when you don't have anything to do? Certainly not! They love to fail at 7:30am on a Tuesday when you're supposed to be leaving for work. What does this have to do with Teslas and other EVs? Well, no battery likes the cold, even if it is large. Also, any EV has the unfortunate problem that it doesn't generate a lot of waste heat. Wait... is that a problem? Well, not unless you live in the northern half of the US or somewhere else in the world similarly close to the North Pole. Normal combustion engines generate a lot of waste heat. In the Summer this is not ideal and all that heat is wasted. In the Winter it serves has a handy heat source for the poor souls inside the car. EVs do not have this problem/blessing. And so, they all have to generate heat somehow. Some of them have heating elements, some have heat pumps. Some Tesla cars can heat up the motor and use that heat. One way or another, EVs need heat for two reasons: 1. To heat up the occupants 2. To warm the batteries. And so, no matter the EV, you will find that they tend to like to keep the batteries over a certain temperature in order to allow for charging and discharging without damaging the batteries.

This leads to trouble for people who do not charge at home. I have quite often said that people should be VERY careful and think VERY hard before buying an EV without any means of charging at home. One of the big reasons for this is the need to ABC (Always be charging!) in Winter. With a source of 120 or 240v power an EV can keep the battery heater on and the battery up to a suitable temperature. Without an AC power source, the battery itself must be used for this. Naturally, this depletes the very same battery you need in order to get from point A to point B. And, thus, we had the recent situations where people ran out of charge while waiting to charge. Don't be those people. ABC. Remember it - Always Be Charging.
Need pictures, links, something to spice this up.
Tesla cars want the battery to be 125F in order to super charge at full speed. They can preheat but you have to use their built-in nav app to get them to do this. Otherwise a cold battery must be heated and this can lead to long lag times where you are at a super charger but it may be hardly charging as the battery warms up. This can take over an hour in the worst case - an hour where practically no charging is taking place. All the while everyone else waits and eats up battery trying to stay warm - both themselves and the battery
