Comment Re:What is an EV "starting difficulty" anyway? (Score 1) 216

I guess if you parked it warm with 20% or less in the battery it could be an issue. I get a warning on the screen if the weather is around freezing and I park at home with less that 15% that I should plug in to charge.
Other than that it could be the 12% battery had died so it couldn't even run the electronics and activate the contractor to the high voltage battery.

My Tesla is really good at thermal management. It uses the heat pump. it runs the motors as heating elements. If you have heat in the battery, it will scavenge that for cabin heating. If I put it in "chill mode"(as in drive relaxed), it will not heat the battery as much and it will scavenge more heat from it.

I noticed that if it is only a few degrees below freezing, it seems to use the heat pump to warm the battery to charge if it has been sitting for a few days without using it. when it gets a lot colder, I noticed it went back to pre heat pump days and used the motors as heaters before charging.

If I travel using superchargers, it will tell me that at location is full and suggest another location. the new(perhaps upcoming) version of the navigation will take into account other cars heading that location to charge.

Now since I can charge at home, driving electric in winter is awesome. Much better experience than my gas cars.

Yes it is easy to solve. VW limit it's cars to 4000 hours / 10000 kWh V2L, which would be plenty for me as a battery backup. It won't really interfere too much with the house battery solutions as those have been rated to 6000 cycles(depending on brand) so If you have just a 12kWh home battery, that would be 7 times more kWh drawn from that in its lifetime.

I don't have power outages often enough to warrant a backup solution but, I would definitely consider it as an option for my next electric car. If I had bought a Hyundai, I would have spent the extra dollars to get the V2L plug.

I am not from the US so I might get this wrong but,
They already did?? The Central Arizona Project? Water from the Colorado River, all the way to Phoenix.

There is not enough water? the Colorado River is dry before it reaches Mexico. Hoover Dam controls the water water management / release so there's a steady supply of water all year round. but the base level of water get really low in dry years because the demand downstream in Arizona and California now exceeds the what can be supplied in dry years.

From experience I can say that I would have no worries about taking my Tesla and drive it from Copenhagen Denmark to Barcelona Spain, without spending one second looking at a map first to scout chargers.
Granted, south of the Alps, even the Tesla superchargers density are a bit lower but they works. And north of the Alps there's so many of them that you can decide by not just when you need to charge but which are located in a place with facilities(toilets, restaurants, cafe etc) you might need. And should a Supercharger destination be full(perhaps because of broken chargers although I have never seen many failed at one time), the navigation will suggest to go to another charger than originally planned because of congestion.

Furthermore, Tesla seems to be very aggressive about building out the charging networks. You might hear stories about people waiting in line at a supercharger, but what you don't hear is that if that happens more often, they will expand that charger, or build another one along that traffic corridor.

I have even seen them a few years ago have employees sitting in the show at Christmas to help people charge or something when there were a lot of holiday travels. Not sure why, didn't ask.

And I wonder why are no one else are being that aggressive about creating a functioning dependable charging infrastructure? Even Ionity(EU version of electrify America) with their EU grants, VW Dieselgate money and other car manufactureres are doing a worse job than Tesla without the EU grants.

At least he gets the point of being able to bike to the office without needing to take a bath upon arrival.
But he is looking for problems that are entirely on the users discipline.

I go mountain biking 2-3 times a week, for different medical reasons(heart birth defects, pain in joints etc), I can't do 4 days in a row with 5 hours active riding in an 9 hour day.
I really don't want an e-mtb because they are heavy and no fun going going down so I do what I can on my regular MTB.
But I have been going on 4 days vacations with guided trips where we had trips each day that I wouldn't be able to do without assistance. So my everyday non e-bike have given me the technical skill for rock gardens etc, some core strength(though e-mtb and fitness center) to be in control of the bike and some stamina.
The 4 day vacation, I used a rented e-mtb and I was able to keep up with the others, even be faster down hill than some of the less trained people. and at the end of day 4 I still got exercise and returned home I better shape than when I left.
I also got to meet a lot of new people I didn't know, hang out in the evening in the bike shop, driving beer and talking about the days events, crashes, climbs and what else happened. Because of the shared experience those days, we had something to talk about and a lot of laughs.
Without the ebike, I wouldn't have gotten out of the house traveled to another country and met with other people and done some sightseeing while getting an exercise.

I am aware of the downsides, ebikes shredding and damaging built and maintained single tracks more than non e-bikes, inexperienced riders getting injured (mtb and non mtb) because they don't have the core strength to do what the bike now enables them to do.
