Auto Makers Announce Electric Car Charging Standard
Overly Critical Guy writes "Auto makers are launching a universal EV charger that charges an electric vehicle in 15 to 20 minutes. The standard, called Combined Charging System, has been approved by the Society of Automotive Engineers and ACEA, the European association of vehicle manufacturers, as the standard for fast-charging electric vehicles."
I could claim that my phone "charges" in 30 seconds, and I'd be correct. Of course, it only charges ~1% in 30 seconds, so that's not very useful.
When they say this charger will charge your car in 15 minutes, I'm assuming they don't mean a full charge. But what DO they mean?
There's no -1 for "I don't get it."
Standardization sounds like a good plan, so we can focus on one format of charging infrastructure.
This is endorsed by Audi, BMW, Chrysler, Daimler, Ford, GM, Porsche and Volkswagen. Tesla is conspicuously missing. The Tesla Roadster and the Tesla Model S are the only electric cars in or near production that are close to road-trip worthy, so the omission is unfortunate.
1. Different vehicles with the same battery profile. Or have standards. Small medium large.
2. If you get to a gas station and they are out you are screwed.
3. It isnt that hard, there are already prototypes. We refill flying planes with other flying planes and you think this is 'far from simple?
4. Then dont include the battery with the car. 20k or whatever for the car and some 'battery insurance' in case you rally your car and the battery falls out. At that point you don't care what condition the battery is in, it isn't yours.
etc etc etc please do go on, the one and only problem is getting an entire nation to roll out stations which is expensive with a slow return on investment and getting auto manufacturers to standardize batteries.

Aerial refueling is far from simple, but it is performed by highly trained operators in billion dollar equipment. And you use that to justify why installing 100,000 battery changers, performing hundreds of millions of changes a year, operated by idiot consumers with cheap vehicles is somehow easy? You might as well say "We put a man on the moon, why don't we all travel in miniature scramjet pods?"

So the only problems are that the infrastructure is too expensive to be profitable and the vehicles are too expensive to be profitable. Sure, that sounds totally viable in a free-market economy. /sarcasm.
Why are people so obsessed with having gas stations for electric cars? That defeats the whole purpose. Charge the car at home and at work, like your smartphone. No trips out of your way, no cruising for the cheapest price, no waiting by the pump, just a few seconds before and after to plug/unplug. If you need to go long distance, take a train/plane/bus, enjoy the view and relax for once in your life. And if your commute is too long, then you're not in the target demographic anyways.
For the cost of installing battery-swap infrastructure in a handful of locations, we could cover a city with standard charging stations. Then you could charge no matter where you park. Even installing networks of the fast-chargers on major corridors will end up being cheaper and more versatile.
Besides, you've seen how long it took them to agree on a standard for a charging plug. Just think how long it would take them to agree on standards for whole battery packs. By the time they finish, we'll have 400-mile Litihium-Air batteries and hydrogen fuel cell backups, and no one will care anymore.
I own a LEAF, and I've heard no such recommendation. They recommend against multiple quick charges per day, but I haven't seen anything about twice a month. You don't want to put the battery through a quick charge when the batteries are real hot, but a battery pack is not going to hold heat for multiple days. Sorry, the thermal mass isn't that high.
Now, they do tell you that the less you quick charge, the longer your battery will last. They say that regular quick charging will leave you with 70% capacity after 8 or 10 years (I can't remember the quoted "lifetime"), and 80% capacity at "end of life" if you don't quick charge, but just use 110V trickle charging and 220V normal charging.
That's not exactly frying your batteries early.
Don't hold your breath on your non-RTFM scenario, dude. First of all, EV owners know the dominant strategy for charging is always going to be charging at home. Very few people are going to be doing a lot of quick charging (maybe cab drivers?). Quick charging is likely to be significantly more expensive per kWh than charging at home, and people just don't buy LEAFs if they do a lot of long-distance (100 miles+) driving. If they did, they'd but a Volt.
Electric vehicles use zero power while stopped, and damned little while moving slowly in stop-and-go with regenerative braking. It's maintaining the highway speeds that kills the battery faster. This isn't like an internal combustion engine, which makes peak efficiency at more-or-less highway speeds and wastes power idling in traffic.
So, your commute was about a mile and a half each way? Would you even bother driving that kind of distance?
In parts of the world there is no alternative. I remember seeing a nice restaurant across a highway from a hotel in Texas once, and after wandering around for a bit I realised the only way to get to t was to get in the car, drive half a mile to an exit with a loop under, then drive back again.

I used to commute half that distance.
Sure, it's only three quarters of a mile, why not break the American mold, get some exercise, and save money in the process? Because I always sucked at playing Frogger, that's why. There are no sidewalks, there are no crosswalks, and there is no respect for pedestrians between here and there. It's good exercise running like hell trying to avoid getting hit by cars going 20 mph over the speed limit, true enough, but running for your life tends to make you show up for work looking sweaty and haggard.
This phenomenon is one of the bigger things that I really wish America, or at least my corner of it, would fix. I actually like to walk, and I'd be happy to walk that distance and more every day if it weren't such a fundamentally suicidal undertaking.
I guess it's all moot now anyway. I lost that job, and now I have to drive 115 miles round trip.
