Might be based on something like this: https://thedriven.io/2020/03/24/siemens-converts-all-lamp-po...

unguarded $100 worth of charging cable dangling from every street post? what could possibly go wrong?

The cable is closer to 300-400€. (7 meter 32A Type 2)

It locks to the pole when it's charging, and the car can be set up to lock its end until the car is unlocked.

Non-issue.

Accelerate faster than a combustion sports car, no expensive engine maintenance etc. And since the only major cost of electric cars is the battery they will go down in price as we get better batteries and very likely get cheaper than combustion cars pretty soon. Electric engines are super simple, only reason combustion cars are even competitive today is that we have invested so much research into building combustion…

There are cheaper and faster combustion sports cars.

Cheaper yes, faster - not many.

I wonder if electrical grids are really prepared for mass adoption of EV. For example, UK is already quite reliant on the HVDC link [0] from France. In 2016 it got damaged resulting in a reduced capacity, which has caused serious concerns at the time. And it's not only about power generation, it's also quite probable that a lot of existing power lines would have to be updated to satisfy a higher demand for electrical…

It's normal bread and butter work to plan ahead incrementally increase capacity over time. Wind and solar also need more transmission capacity. The transition is after all happening relatively slowly, there's not going to be a EV flag day.

Of course there may be dysfunctional transmission organisations that have been able to hobble along without anyone noticing for a while that get caught by this, but that's just something that needed to be fixed anyway.

Maybe in the UK, but not where I am. It was -26 this morning. Batteries don't handle such temperatures well. And the nearest civilian airport is 400km away. I haven't seen a single all-electric car in my town since I moved here over a year ago.

Weirdly, the most popular car in Ulan Bator (capital of Mongolia) is the Prius because in their super cold winters it, of all cars, starts and runs best in the cold.

The Prius Secret is that the engine is so loosely tuned it doesn't have much friction when starting, the oil also has the viscosity of colored water :)

Best of all it uses the EV motor and battery to crank the ICE engine, there's no separate weak-ass starter motor.

Had mine in -30C weather for a weekend, cranked it on monday night and it just - started. Like it had been vacationing in the French Riviera.

Compare that to my old Diesel VW, which - when cranked at the same situation - made a sound like someone was strangling a moose. I had two attempts to get it to start, then the battery would run out because of the friction caused by the thick-ass oil.

This is a Tuesday in Finland.

The EV will just start. You press a button and it turns on. In under 5 minutes it will be so hot inside that you need to take off your jacket.

Yes, range will suffer if you don't pre-heat the battery (by plugging in the car over night), but I still get 200km range off my car even when it's up to -30 outside.

That HVDC link is 2000 MW, consisting of 2 independent 1000MW systems even built by different manufacturers. Sounds very similar to risk that the grid has to manage (with backup power etc) with normal power stations. The UK is much less dependent on cross border electricity than most European countries.

One side of this that doesn't seem to get looked at much is how many ICE cars are on the roads that could be converted. Doing conversions at high volume would be very labor intensive, but it would give dealerships and mechanics something to do, and it would generate less waste than replacing whole cars. Right now it's kind of on the edge of being practical, mostly because of the batteries. They're expensive and bulky…

Who is in this space for consumer vehicles? I'm only aware of Hyliion for semi trucks.

There's EV West:

These don't include batteries or battery boxes. The former are expensive and the latter are generally a huge hassle to make.

CanEV makes motor-transmission adapter plates and couplers for a surprisingly wide range of cars.

There's Zero-EV in the U.K. I only know about them because of a Youtube video series where they convert a Miata. Looks like they're selling a Porsche kit at the moment.

There's probably some others I don't know about or have forgotten. I don't think anyone is doing this on a large scale.

"Lots" is still relative though. A large employer near me has something like 50 chargers available in their lot. Of course, on a normal workday, 8,000 cars are being parked there. If 4,000 of those employees start driving electrics, I'm not sure it would be possible to accommodate them.

Do you really need 4,000 chargers though? I don't think so. Between charging at home and charging at work, it shouldn't be necessary to occupy the charger every single time you pull in. Maybe once or twice a week, depending on your commute. A long range Model 3 has as much range as your average gasoline vehicle... how often do most people fill that up? Seems to me if 4000 employees go electric and you can slow charge…

Pre-pandemic I was commuting to a large bay area employer. About a ~hundred or so chargers in the parking lots.

The choices were to either arrive very, very early (I mostly left after 7pm so it was ok but on days when I had to go at 5pm it was a big problem, didn't have time to get enough charge to get back home.

Also, there's not enough power available to feed all the chargers simultaneously. So when all chargers are used and charging, the power delivery dropped to ~1.5kW. As cars started to get full and stopped drawing power only then power delivery would rise later in the day. So there's no way to install a thousand+ more chargers, there's not enough power delivery available.

I recently got a plug in hybrid, due to road trips a full ev is not great for me. The all electric range is so nice to drive. But it makes me realize how loud the ICE is after that kicks in, which now annoys me. I’m excited for when electrics will get a 500 mi range. It will happen.

How often do you actually drive 500 miles without stopping?

My ass gets numb after 200 and _I_ need to stop. =)
