Title: Electric Charging
Post by: AutobahnSHO on October 14, 2017, 07:59:01 PM
Finally some news that I've expected...      Shell sees the future in Europe and bought a recharge station company to add to it's rollout.

It's wise for oil companies to hedge their bets like this. The price of solar and wind are dropping like crazy.

Suggestion. We should have a CarSPIN board covering EVs (plus I guess plugin hybrids), the technology behind them & their supporting infrastructure.

I was just reading about a new charge point for homes that have PV panels (or even wind generators). It make decisions about sourcing the charge: e.g. whether to favor home-generated juice rather than sending it out to the grid, or maybe save the home generated stuff for the Powerwall and only charge the car with low-tariff off-peak electricity from the grid.

The energy density of batteries is still much lower than that of gasoline; we don't have a Moore's Law ramping up batteries every year as we did for CPUs. but I think that disadvantage is being offset to some extent by smart management controls we're now seeing.

The energy density growth curve is still pretty steep. It'll flatten out eventually but we're not there yet. (BTW, Moore's Law for CPUs isn't really a "law" anymore; single-core perf has been flat for years now)

EV subforum is a great idea BTW. We should deprecate some older less used subforums though, just so we're not spread too thinly.
Title: Re: Electric Charging
Post by: 12,000 RPM on October 16, 2017, 02:37:33 PM
Also keep in mind that batteries only have to reach ~30% of gasoline's energy density to match up to the average car's efficiency.

I'm still skeptical about a need for on the go charge stations. We already have them in our homes, and utilities can just add higher wattage street charging by upgrading transformers. Heck, through public-private partnerships they could offer quasi subsidized high capacity home charging stations. If the market saturation really reaches critical mass those things wouldn't seem so far fetched.

I think a subforum dedicated to "all things future" in the automotive realm would be pretty cool. I have a bone to pick with that goofy alarmist Malcolm Gladwell piece.

No, most of the higher end newer bikes are all mid-drive. Hub drive is clunky and old compared to mid-drive setups.

Correct. Such ebikes (motor on the crank) have been all the rage (inducer) in mountain biking world and from what I can tell, is the way of the ebike going forward. They work well apparently.

Currently, in my area, these are considered motorcycles and cannot be used on trails by law. 250W continuous will have you blowing by 99% of riders (have to pedal for power to be applied).

Yeah, the mass is centralized more, and it allows you to take advantage of the chainring gearing as well, instead of just the cassette gears as with hub drive. Plus, the wheels are just standard wheels, so removing and installing the rear wheel isn't any different than a regular wheel.

I'm surprised they're considered motorcycles, though. Unlike hub drive, don't mid drive bikes have to be pedaled in order for the assist to work? IOW you can't just sit there without pedaling and have the motor do all the work for you like you can on a hub drive bike, unless there's some different system I'm not aware of.

I can see how it would be irritating to regular MTB'ers, though.

Most trails around here are multi-use - bikers, hikers and horses, and bikers have to yield to the other two. Ebikes scream, esp. on the flat. It's a recipe for a major wreck and could jeopardize biker access.

We considered an electric car because the city will give you a dedicated charging spot in front of your house. But good luck enforcing that in a city; you'd be on the phone with the police asking for cars to be towed more often than you'd be parking where you're supposed to park. Then, when you do park there, you're asking for vandalism.

I really don't think electric charging is viable for anyone who doesn't have their own garage to do it in. Some punk kid would walk around unplugging all the cars all the time if the charging is done outside. Can you imagine? I mean, if we live in a world where someone would smash a windshield for no reason, electric cars are a perfect target for sowing that little brand of punkass chaos.

Yeah, some sort of lock that uses the car's key to lock the charger onto the receptacle would be good.  But people can barely be bothered to use keys anymore. So they'd have to make it some internal mechanism like an automatic door look is now.

Great idea.

But I would guess the money will go more towards private garages with charging as part of the rent (or metered and pay for what you use plus a space).

Building private garages isn't going to help current infrastructure. Plus, from what I've seen around here, most new housing developments are for apartments/condos with no garages.

Around here, you're not allowed to build without a garage or spot for to each dwelling. If you build a building with 50 apartments, you need at least one spot for each one.

This is a valid point. How do you protect charging apparatus from the thuggery of the skells that infest our cities?
Or even accidental damage from innocent people crossing the streets & snagging cables.

Many of the grocery stores here have electric charging stations. The city codes require mixed commercial/residential buildings have a certain number of charging ports. Higher voltage charging is reducing the charge time (IIRC we have 1000V chargers which give heavy heavy Teslas about 120 miles per hour charge). Batteries are getting more energy dense, so charging doesn't have to happen as often. Some companies offer charging as a cheap perk for employees; it's a reasonable transportation benefit if you consider that a 60KW car can be filled for under five bucks.

IMO we are converging on EV feasibility from a number of angles at once.

And what about people overfilling their cars with gasoline, or using bad filler equipment?

There's a whole lot of software monitoring and two way serial communication going on while it dispenses electricity. I would expect any sort of abnormal discharge would cause the unit to clamp down and enter maintenance-required mode. It's probably still safer than people messing around with gas.

Of course there's short and arc protection built into them; but rarely is any of that quick enough.

Gas pumps exist almost exclusively at gas stations; which means there's at least some sort of active oversight. When you have chargers scattered all over the city, and vehicles charging unattended, it becomes a different story.
I'm not saying it's a deal breaker, but a potential concern.

Which city? Seattle? As if they need any help with their scarcity of parking...

Capitol Hill is a fucking nightmare to find parking in on weekends. You can literally while away half an hour of your evening just looking for a spot. And then it turns out it's illegal b/c of some kind of encumberance. I seldom visit Seattle anymore.

Yes, Seattle, and this acquaintance (relative of a good friend) is apparently quite the political thing around town - and they have been successful.

It matters. Since most of Seattle's new residential construction is high rise buildings, there is indeed theoretical (underground/lower floor) space for parking, but they have been successful in changing zoning to lessen the number of spots available.

Capitol Hill is a PITA but I manage. Sometimes will park at friends too.

There's zero vandalism? I find that hard to believe.
Well, I haven't experienced vandalism, nor have I seen any talk of it on my subdivision's Nextdoor page, and it's a neighborhood with 28K houses and its own school district :huh:

Well, there are some apartments and townhouses too. But like I said, haven't seen any issues with vandalism. Some break ins though, but rare enough that they freak people out when they happen.

But you consider 28k houses a neighborhood?  Do you think a school district is always a neighborhood?  Do you know all of these 28k+ people?  Your definition of a neighborhood is fucked. :lol:

Absolutely. I've lived in Manhattan and Harlan County KY. I'd much more consider a place where you see people all the time more "neighborhoody" than somewhere you can't see your neighbors. There are plenty of block organizations and clubs that get people together here.

Trying to think of how you'd vandal/thief-proof charging points on streets or in communal parking areas. I think the yobs would lay waste to it all... so you're pretty much SOL unless you have a secured garage or live in a crime-free area. Or go with wireless charging.

Tesla supercharger delivers juice at 480VDC.... that should be enough of a deterrent.

High crime areas will probably be the last folks to adopt  to electric cars anyway.

I think the vandalism angle is a bit overblown, especially the for-profit stuff. Sure people steal copper gutters, piping, A/Cs, refrigerators, etc...during smash and grabs or at abandoned property, but they're generally not chopping down power lines or other electrical systems w/ active current. And I don't think it's because they're scared of getting caught. As for the minor mischief of unplugging, eh, maybe get a lock for your home charger, but otherwise just deal. There is nothing stopping a prankster right now from letting the air out of one of your tires, but everyday we wake up and 99.99999999% of ours haven't been touched.

TL;DR version: It's a mess out there & nobody's going to take EVs seriously until a worldwide standard is in place.

My vote would go to whichever is the fastest and nicest to use.
But of course that's not going to happen.

Early sign of a business description morphing from 'oil company' to the less-specific 'stored energy company' or somesuch?

Shell to open electric vehicle charging points at UK petrol stations
Shell is opening a first wave of electric vehicle charging points at its UK petrol stations, in a sign of the far-reaching changes under way in the transport and oil sectors.

Drivers will be able to recharge 80% of their battery in half an hour at forecourts in London, Surrey and Derby from this week, with a total of 10 service stations to be equipped with rapid chargers by the end of the year.

That's why the current electric car model doesn't work with the current fuel station model. Fuel stations will have to have large parking lots full of chargers to service large numbers of cars as opposed to 4 to 8 pumps for gas vehicles. Electric car charging will likely require regular stores and restaurants to have chargers so that your car can charge while you shop or eat (this is already starting to happen). It may even work to have neighborhood chargers. I could even see HOAs putting in charging areas.

It already is for my co-worker. He charges his Volt with solar power at his home. When he drives to work he parks at Costco about 1.5 miles away and hooks it up to their charger and pulls his bike out to get to work. He then bikes to Costco at lunch time to pick up his car. Rinse and repeat.

this is so much more sane. People will value shorter commutes and/or garages which offer charging.

Exactly. We already have the charging infrastructure in our homes. The only hurdle is in apartment complexes, but once this shit reaches critical mass they will find a solution for that.

I think at some point they will add supercapacitor bank to the traditional battery.  The capacitor bank could be useful for small mileage trips but recharge extremely quickly.

I had that thought too. Nobody (preppers excepted) has gasoline filling infrastructure at home, but millions have most of  what's needed for electric charging at home. So the gas station forecourt demand for charging will be lower. I'm guessing Royal Dutch Shell at al will be figuring out slick charge point set ups and offering them at grocery stores, restaurants, etc.

The (small) mall has a row of them here, one the movie theater/food court side. We get lots of Canucks driving down and visiting, or I don't think the mall would exist.

I saw a few superchargers at a Hotel right off I-80 in Evanston, WY. Google map that one and tell me where they were coming from. ;)
