Tesla: amazing car...with one teensy drawback...

[2011G6E]

Look...I love the Tesla...I'd have one in a heartbeat.

Well...I would if I was allowed to by the electrical company...depending on the local substation.

THE world’s biggest-selling electric luxury car goes on sale in Australia on Wednesday December 10 but the $100,000 Tesla sedan may have its plug pulled because its special charger is too big for most local electricity grids.
Unlike other electric cars, the Tesla cannot be recharged via a normal power point and requires a special charger to be installed at home or work at a cost of up to $10,000 -- and may also need to have the local electricity sub-station upgraded at a cost of more than $50,000, according to experts.

Tesla issued a map showing future charging points will be installed in Queensland, NSW and Victoria by 2016, but it is yet to pinpoint the locations.
Electric cars already on sale in Australia can be charged on 10 amp household power or require a relatively simple 15 amp upgrade for about $400.
But because the Tesla requires a 40 amp single phase charger, the Master Electricians Association says there may be restrictions on upgrading household power supply and connecting to the local electricity grid.

At a minimum, the 40 amp single phase charger that Tesla uses exclusively will need approval from local electricity network suppliers.
When Tesla eventually switches to a three phase 32 amp charger, the upgrades to the electricity system in the average home will cost close to $10,000.
Most modern households with single phase electricity supply have a maximum capacity of 63 amps, however there are restrictions on how much energy any one item can draw, and each household needs to be inspected to determine how much spare capacity -- if any -- there is to install a Tesla charger.
“It is highly unlikely the mains cable coming into the home switchboard will be adequate to carry the extra 40 amp load to recharge the car,” said Master Electricians Australia spokesman Greg Bryant.

...cont's...

Whoops...seems there's no such thing as s free lunch. Yes it's powerful, yes it has a realistic range before recharging...but no one saw this awkward little problem coming. Green groups seemed to think the emergence of such a car meant that everyone would be able to change over to electric cars of a similar design.

Not without billions spent upgrading the electricity grid, substations, and massive costs to households in upgrading to suit the new charging points needed for this type of technology...

[Top_Ghia]

Damn! 40 Amps is a lot of current and will cost a packet to charge. So much for electric cars being free or cheap to run.

No worries, I am an electrician. I will install my own socket

Of course there's the little niggle of having to let the local power mob know what you're doing as substations and power lines to the house may not be able to handle the output. Just a socket? Yeah fine...but there's everything else that goes with it.

Love the way some guy drove one to Darwin. However a huge truck with a massive generator had to follow him all the way...yep...that's clean and green...

[arronm]

Not really kettle, toaster, one air con and my spa will pull more than 40 amps. So a car plugged in will be no problem.

BUT if everyone had a telsa then it would be an issue

[2011G6E]

I don't think it's about "pulling" 40 amps. It's to do with the power supply coming into the house. For now it's a 40 amp single phase, but it will need upgrading to a 32 amp three phase.

It says quite clearly "Most modern households with single phase electricity supply have a maximum capacity of 63 amps, however there are restrictions on how much energy any one item can draw, and each household needs to be inspected to determine how much spare capacity -- if any -- there is to install a Tesla charger."

So it might be a choice...do I use any other appliances while I'm trying to charge my car up, or spend an inordinate amount of money upgrading the whole house so I can power an outlet for the car and watch TV at the same time while the fridge is going...?

[arronm]

Yep. You won't be able to charge the car while you are making breakfast

[2011G6E]

I'm sorry...but as great as this car is, like every other electric car, they will only ever be an inner city novelty item for cashed up environmentally conscious people.

Green groups will say "Well they're not meant for everyone", but that's not the point. If you want us to move away from nasty fossil fuelled cars, then they have to be for "everyone everywhere". And they aren't, and never will be until the meet a few basic requirements that would mean they match or surpass petrol and diesel cars.
Namely, four to five passengers and luggage, able to drive at the speed limit and normal highway driving with a full load and air con going for a range of around 600km, with a five minute recharge to full capacity. Simple. Until they can do that, they will, as I said, remain an inner city novelty, no matter how good they are. Sad really.

[commodorenutt]

Exactly - they are a novelty, and they're simply shifting the pollution problem to somewhere else when Australia relies so heavily on coal fired power stations (and gas). Ironically, all the green NIMBY's are happy though.....

And the way power prices are going, how long before a "recharge" costs more than a tank of petrol?

[Freiherr]

No thanks. I am sticking with my XR8 order. Meets all the ease of use criteria apart from the 600 km range, which a jerry can in the boot should easily fix.
Another question for thought - how does the government work out the fuel excise on the Tesla charge top up? Surely the car energy tax will be different to the tax paid on the morning toast.

[Yellow_Festiva]

I take it the uprated charging hardware is required due to the fact that it has such a large battery?

Looking at another EV (Mitsubishi I-MiEV), it quick charges in 30 minutes (probably on 3 phase) yet takes 7hrs to charge using a regular household outlet. God for a max range of only 160km.

Tesla is a much larger car, has a much larger range as well. I wonder if the Tesla's charging time using standard house supply is measured in days and not hours? Hence the requirement for such a beefy supply.

Any word on the charging time should you spend the extra coin for the upgraded supply?

I still think 'quick swap' stations are needed, not 'quick charge' stations.

The only problem with quick swap stations is the battery bank is usually a massive pain in the *** to get to/change out, plus precautions about high voltages need to be taken.

Plus you would be a bit inconsistent with range I think because you'd be constantly getting used batteries in there and you don't know how far down they would be on capacity.

Hopefully we're not far away from a breakthrough in battery technology

Very true, but this can be overcome by having a standardised system that all manufactures follow. If the ability to quick swap was designed into the car it wouldn't be a problem. Battery packs can come in 3 sizes, much the same as we have AAA batteries for small devices, AA batteries for larger devices and C / D cell batteries for larger devices again.

Petrol is a highly flammable liquid, we pump millions of litres of the stuff a week with next to no issues. Safety is an issue, but those considerations need to be factored into the design - much the same with other electrical devices we use on a daily basis.

Perhaps have a guaranteed minimum (90%??). Again, we see this already with our unleaded / E10 stuff where it ranged from 91-95 RON depending on the blend and who you buy it from.

All new(ish) technology has its teething problems. There will always be ways to work around most issues and compromise on others.

These days, 'time is money' and I don't see people stopping for 30 min to quick charge their car.

I personally love the idea of electric vehicles, but I don't think they have it sorted it out for cheap mass consumption - yet. This Tesla issue highlights this.

[Cobra]

In 100 years, when every car has long been electric, Tesla will be remembered as the Model T of the electric powered vehicles. Teething problems today will be sorted over time.

[warpsp33d]

That article isn't really worded very well.

You don't strictly need that capacity of charging.

You can charge a Tesla using a normal power plug... it'll just take a while. Not an issue though if it's your daily driver and you plug it in overnight.

The Tesla has various different charging options that range from a single bog standard power point (that will take like 24 hours to fully charge the battery from empty), all the way up to the 80A super chargers (that will charge it in something like 3 hours - 80% charge in 30 minutes or something crazy like that).

Like all the huge numbers of people that were fooled into getting LPG fitted to their cars when the government was heavily subsidising it and then once enough people had converted, oh look, they whacked up the excise that high that is is hardly worth having an LPG car any more.

It will come...once electric cars are in decent numbers (and in city areas they will be), they will bring in some sort of tariff...

[malazn mafia]

How large is a 40amp petrol generator? Just put one on a trailer for long trips and would probably be more economical than a petrol car anyway

[phild12s131e]

A few years ago they ran a Tesla in the Darwin to Adelaide solar challenge. There was much back slapping on the results from a number of supporters but it was when you actually looked at the complete results and the level of support that was required to keep it going that it was obvious that it was little more than a day to day commute vehicle in the more populated cities. The likelihood that many roadhouse's would be in the position to provide the power requirements from their self sourced generation capacity to cope with the Tesla are a long way in to the future. Also, the speed at which they had to cruise to allow the range they got would make for a very boring trip and the only people that would be happy would be the "Speed kills" brigade plus Skippy and his friends.

In 1988 we did a trip from Darwin via the East coast and back up the centre in a 1982 KA Ford Laser with 2 adults, one 3 year old, plenty of luggage and a roof top storage box. We did Adelaide to Darwin in just under 2 days with a good nights rest in Alice and all with unlimited use of air-conditioning, headlights all day, some use of driving lights for a while and even a quick visit to some friends while there. Only other support required was the fuel stops and a few meals. When the Tesla, or any other hybrid, can match or beat that I'll think about becoming a believer.

The problem with slow chargers is your without a car until its done, I would imagine for battery longevity doing partial bit charges would be a No No ? .......
I used a power calculator, correct me if I'm wrong
40 amps X 240 volts = 9600 watts. = holy **** ? That is a god awful lot of juice if that is correct.

[Bent8]

Electric cars are not a cleaner tech anyway when you really think about it...

Imagine if half the world suddenly switched to electric cars.. the demand for electricity would be astronomical.

And where does electric power come from?... coal, nuclear and fracking !

Until we have the tech to deploy solar recharging stations, this is all just a big waste of time and money.

To all prospective TESLA owners, enjoy charging your new toys.

[FGX335]

Just waiting for the first person to forget it is plugged in, and drive off down the road still connected to the charger. I'd be hoping there is some sort of quick release coupling...

Power requirements in terms of charging is only half the issue, don't forget the large battery banks these cars have, and the power requirements required to obtain and process the chemicals / elements that make them up.

[GT450]

True but wouldn't it be nice to wave bye to the opec countries . The sheiks might have to shop on a budget for a change , maybe just buy a ferrari in one colour instead of one in every colour.
It won't happen in my lifetime and I can't say i'm unhappy about that ,I do like my V8.

the first cars were created 120 or so years ago as a better horse. it took several decades of design and improvements before they became better than the horse and another century to get to where we are today, with multiple massive industries geared towards their production, maintenance and refuelling. many trillions of monetary units have gone into them to achieve what we have.
Electric vehicles fly in the face of some of those massive industries. and many who don't like change wont accept a potential inevitability.
Electric cars are coming, their propulsion have advanced way quicker from their beginnings than the internal combustion engine to the point they can be an alternate option.
In my mind we have ways of producing energy for powering electric cars et al with significantly reduced environmental, social, and health issues than the status quo and as such see a positive future for electric transport.
Yes they are expensive and still limited compared to the horse but they are closing the gap quickly.

Can't happen, car has interlocks for idiots.

The article is poorly written, the fixed single phase charger can be configured for 10, 15, 30 or 40 Amps, depending what you house wiring can support. There is a 32 A 3 Phase charger due early in the new year.
I know my house can support 40 A without issue, I just had 40 A single phase ran to my shed (house is 3 phase).

The Super Chargers will be rolled out and will charge the car to 50% in 20 mins. This will use solar power. Brisbane to Melbourne is planned to be covered by 2017.

I'm sure that, literally at the start of last century, people were saying the same about the Lohner Porsche.
Nearly 120 years later, and this is all the development in regards to EVs we have seen!?

the concepts designed then have come a long way since the early 1900's

'The Lohner-Porsche's design was studied by Boeing and NASA to create the Apollo program’s Lunar rover. Many of its design principles were mirrored in the Rover’s design. The series hybrid concept underpins many modern railway locomotives, and interest in series hybrid automobiles is growing rapidly.'

[mik]

Maybe the hybrid will win out in the end, it gives you the best of both worlds, the ability to run on either or combo as needed.
With all the bloody railway crossings across melbourne sometimes at times I wouldn't mind a hybrid.

[Davehoos]

People today refer to Model T not because it was an engineering leap or even a great product, but what it allow society.

Tesla will only be remembered in history if it engages society like Steve Jobs and home computors.

Received an excited club journal that refered to the first deliveries of P85 and the next years P85D. no mention of its ability-just that its here.

[CyberWasp]

So let me get this straight.
To be green and environmentally friendly we have to modify and increase the capacity of our Power Stations...........I...seee.
Because we all see smoke coming out of Cars but if we moved the smoke to Power Stations no one will see it and thus it is more environmental.
I think I understand now.
