The standards war for car charging is going to be a big mess:
there is the standard which i3 is using
http://en.wikipedia.org/wiki/SAE_J1772
that in itself has (incompatible?) AC (2 levels) and DC (3 levels) variants
Tesla does it so it's definitely possible to manufacture the adapters fairly cheap. From what I've heard the Tesla plug doesn't require a licensing fee so that certainly helps keep the price down for adapters.
Even when everyone's compatible, will you be able to charge on another company's charger? Or will it be like the ATM issues of the past? "You can only withdraw money from your own bank's ATMs"...
Maybe they'll add premiums for non-partnered manufacturers, or secretly charge them much more slowly, sort of like the Comcast and Verizon of the roads.
Aren't there ways to use adapters for increased compatibility?
I don't see why companies wouldn't want to partner with Tesla, especially now that they have a significant number of charging stations and I don't think they charge a licensing fee for companies using their plug design.
The BMW vehicle would need the adapter to go the other way though, and apparently the cost can be reasonable. There's no reason why the j1772 to whatever the supercharger connection is should be greater than ~$100.
I do appreciate the fact they do not intend to limit which cars can use the chargers, that is a great first step in adoption.
Their choice of providing for on board range extenders is a probably a good bet as well. Myself, I could do fine with an i3 because when I need to take those few really long trips each year I won't have to adjust my route to do so.
Does anybody have an account of how unleaded/diesel fuel cars came to have a standard nozzle for filling up? It might give us an insight into how this particular standards battle will go down.
To be honest, the standard for a gasoline nozzle is pretty easy. The hole needs to be bigger than the hose, that's it. There are a lot more variables with an electric plug.
The standard for the actual fuel composition must certainly be the harder part when considering a classic ICE.
In the early 70's cars were being built with catalytic converters, which necessitated the use of unleaded gasoline because leaded gas would coat the catalytic material in the converter and ruin it.
Cars designed to use unleaded gas would have a fuel filler with a smaller hole in it, and unleaded pumps would have a nozzle that fit in the hole, while leaded and diesel nozzles wouldn't.
I don't know the whole story, but there is (or was?) an organization called the Gasoline Pump Manufacturers Association that dates back to at least the 1930s, which seems to have some role in it. Also quite a bit of government involvement, since the measuring parts of the pump fall in the category of "weights and measures", which have been regulated since quite early in U.S. history as an anti-fraud measure (e.g. butchers were traditionally required to use an officially certified scale).
I think this is the wrong way to approach this. So every car manufacturer is going to have its own charging network? Do they even realize how expensive that's going to be? Not to mention something their customers will hate. They all need to get together and create a standardized network that is both solar powered and can charge the cars very fast.
Of course these charge points should be created by the same people that run car parks. Its an additional profit opportunity and a customer draw.
If I owned a EV I would be parking in a car park that was 50% more per hour if I could also charge up. Or they just factor the cost of parking into the electricity cost.
Currently, the EV charging points in my area are all free to use, subject to a £10 annual registration fee. Having taken delivery of a PHEV last month, I'm very happy :)
The biggest problem is that many of the charging spots in car parks are often taken by non-electric cars.
That's Wired editing. They wanted a BMW vs Tesla ( see "Range-Handicapped i3", "Epic Road Trip" ) while in reality, BMW just came up with a small charger to improve the current non-Tesla grid.
The rest of the article is more factual. Except for Tesla, most electric car are meant for city use, small range. In Europe it is quite common to live in a flat with no charging facility at night, so there is needs for a proximity type network. ( For example, I spend 90% of my time in London with the car on the street, buying a Tesla is not possible first because it is a huge car, secondly because I would need to take a trip to the one station 20 min from home on a regular basis )
Imagine if you could only fill up your current vehicle at certain gas stations. If EVs don't come to a standard charger they will be severely hindering that market. There are a ton of obstacles why not put one more out there for arbitrary reasons.
I believe that there is only one bad apple among cellphone manufacturers that didn't bring this change to the USA. But I guess that is to be expected with Apple and they might have made millions inconveniencing their customers.
There is more than one way to build our charging infrastructure and we don't yet know how it's going to work best. Tesla's require a lot of power, BMW's doesn't. Our electric grid can support different amounts of power in different locations. Our driving behaviors haven't yet dictated what's going to work best. Etc etc.
I think the cost of adapting charges to work with multiple models of car is low and the benefits of experimentation at this early stage is high.
I approve of this phrase. We usually see the term "range anxiety" which would indicate some kind of emotional problem with the customer rather than a problem with the product.

then there is this with a completely different plug http://en.wikipedia.org/wiki/CHAdeMO
and another standard http://en.wikipedia.org/wiki/VDE-AR-E_2623-2-2#VDE-AR-E_2623...
China will use yet another one http://www.longtailpipe.com/2014/02/chinas-electric-car-fast...
Oh and then there's Tesla's supercharger network

If you're in the US, you're probably screwed (because liberty)

I owned one in the past and crossed the border between 3 countries everyday (Europe ...) - so I had 2 different adapters in the car always.
Or every car comes with 12 or more converters stored in the trunk...

It's more like ‘up to 60%’. i3’s battery is 18.8 kWh.
And Superchangers are 120kW. So they are just joking about that “the answer to Tesla’s Supercharger Network” part I guess.
