Electric vehicle charging V2G

It’s no news the ACT Government is pushing hard on its commitments to tackle climate change, with the Territory committed to net zero emissions by 2045 and the sale of new fossil fuel cars will be banned from 2035.

Electric vehicles (EVs) are also cheaper here than anywhere else in the country due to a combination of no stamp duty, free registration for two years, and – from 1 July 2024 – emission-based registration fees.

Canberrans have dutifully responded to the point where one in five new vehicles is electric. That’s triple last year’s ratio.

But there is a hurdle: infrastructure. It was raised in a submission to the ACT Government’s recent ‘Inquiry into electric vehicle (EV) adoption’ by Civium Strata Management.

Alex Boundy is a licenced electrician and general manager for the Facilities Management arm of the Civium Property Group, helping manage buildings all over Canberra. He says government policies are “great” and developers and businesses will respond with solutions, but the process can’t be rushed.

He says too many local EV owners are pressured by salespeople to simply slap a charger on the wall of their private car space, with little thought to the building’s future energy needs.

“It’s no different to a budget,” he explains.

“If you’ve got $100 and you spend all of it, you’ve got nothing left over for a rainy day. Translate the dollar figures to amperage, and if you go and install an EV charger station which runs at 100 amps, you’re already at capacity, so to get anything additional, it’s going to be big money. And that’s without knowing if the energy supply authority will give you that, or if it’s even available on your street.”

It’s already a problem in built-up areas such as Kingston or Woden, where the street’s substations are running at capacity. For instance, to charge up Transport Canberra’s new electric buses, Evoenergy has to run 12 kilometres of new cable from the Wanniassa Zone substation.

And with the clock ticking on the city’s gas pipelines in accordance with the government’s policy for no gas by 2045, more and more electrical appliances will place greater demand on the grid.

“With everything going electric, there has to be some serious consideration of how the infrastructure can support that to avoid us struggling in peak times like South Australia did,” Alex says.

“We need heaps of electricity.”

The technology is emerging – in the forms of ‘vehicle-to-grid’ (V2G) systems and batteries – but in the meantime, Alex encourages body corporates and owners corporations to take a more thoughtful approach when considering the installation of EV chargers.

“Have a true understanding of what you’re building uses and when and where it’s used,” he says.

“We can work with electrical engineering firms to log data over set periods and get an understanding of the building’s usages. We compare that to the maximum demand calculations from the building’s construction and the sizes of the incoming cables and associated switch gear to truly work out what additional capacity we have to play with.”

The process costs between $3000 and $10,000, depending on the size of the building and level of investigation required, but Alex says it saves money in the long run.

“Take a breather, get the actual analytical data and then be a well-educated owners corporation before you go to market,” he says.

From here, some elect to hold a vote among residents to find out who is likely to buy an EV in the next five years before settling on a communal charger as the best return on investment. For others, it’s about allocating money in future budgets for installing chargers later.

Ultimately, Alex expects the future of EV charging will follow the service-station model, with more communal and fewer private chargers.

“If I were to crystal ball it, there needs to be a big public charging network for EVs to be successful,” he says.

“The whole psych has to change, particularly the position of owning an EV means you have to be able to charge it in your own car space.”

Given that EVs are just massive lithium batteries on wheels, common sense would suggest outdoors charging only.

@stevew77
So, do you only charge your mobile phone outdoors, genius.

A Nonny Mouse10:03 am 12 Jul 24

I would much prefer to have slow charging in my own allocated parking space than a shared faster charger that requires me to move my car at inconvenient times to let others in to charge. The ‘service station model’ that is advocated here might be a reasonable stop-gap while the number of EVs in a building is low. In some buildings it might be the only practical option but it is not the best and not what I would aim for. It is important to get away from petrol pump thinking. Charging where you live does not need to be quick. You can trickle charge for many hours while you are home.
It is not hard to ensure that EV charging does not add to a building’s peak demand. At the simplest level, it could be just a timer that cuts the power to the carpark for the few peak hours in the evening. More sophisticated load management can turn all the cars’ charging rates up and down to track the rest of the building’s demand going down and up so a set total is not exceeded.

The vast majority of buildings in the ACT would be rated for fires of 3 hours before structural failure occurs. Given that lithium battery fires burn for longer and with greater intensity the risk they represent is too high.

I wouldn’t want bulk petrol stored in the basement of my building and I wouldn’t want a bank of EV chargers or walls of lithium batteries.

Public or external charging points are the way to go IMHO.

Concerning that articles like this one are not proof checked.
In relation to available electrical power distribution, the regulators are installing neighborhood batteries and these are appearing already in various neighborhoods.
The issue is more about balancing power.

Various buildings are also installing batteries to address the demand, and yes in Bodycorporates the Owners might find they need to install batteries if they want to randomly charge EV vehicles.
Perhaps talk to your electrical provider first as most offer special and very attractive deals interest-free.

The electrical power is all renewable energy, something that you discuss with your electrical provider, otherwise, you will pay more for none renewable energy.

Many properties also add solar panels to reduce the power purchased, and many ev car owners have for some time now been charging their vehicles off the grid. ( Approx forty panels if without wall batteries).

Research has shown that combustion engine vehicles are twenty times more likely to catch fire than ev vehicles. ( The issue with ev and hydrogen vehicle fires is the intensity of the fire and the difficulty in putting out a smoldering fire)
Some buildings might need to update their fire sprinkler systems or install safety switches linked to the fire equipment if all their parking bays are electrified.

devils_advocate12:38 pm 18 May 23

Nope.

The issues with EV vehicles are:
-the fire cannot be extinguished it basically has to be left to burn itself out over many hours/days with continual monitoring
-unlike ICE vehicles the smoke from the batteries is highly toxic, meaning the fire brigade personnel cannot go into a basement to fight the fire (fair enough why should they risk injury or death for a misguided political ideological crusade?)
-the fire hose spray (and associated mains pressure) therefore has to be able to reach all points of the basement from the entry point
-sprinklers are effectively useless in extinguishing an EV fire and upgrading them achieves nothing
-the basement and all staircases have to be fully fire separated from living areas and the fire rating hours for the walls increased
-the head of the fire brigade has been unable to give a firm answer on whether it is financially or technically feasible for existing buildings to be upgraded, stating there have been examples of it occurring and it is a case-by-case assessment

So I’ve been saying it for about three years now: In Comments in RiotACT and TCT, to the NRMA, to David Pockock to the ACT Government and the Canberra Greens. My comments have been dismissed and/or derided.

Lithium Ion Battery Cars are the wrong technology basket to be putting all our eggs into. There is range anxiety, there is charging station rage, there are battery fires that are extremely dangerous and cause catastrophic environmental damage (and will increase in frequency as the Li-Ion fleet grows. The minerals that are used to make the batteries come from mines that cause a great deal of environmental and socio-economic damage, the batteries have a limited life and are not easy to recycle and we’ve kicked that environmental problem can down the road seemingly without a real plan for its resolution.

Now you are being told something that I’ve known for a while: As the Li-Ion EV fleet grows, there will not be enough electricity for everyone to charge their vehicles as much as they want when they want. The system is already having trouble coming with the very low demand.

All the while there is a technology that does not suffer from as many shortcomings, but is getting nowhere near the same level of investment and government support: Hydrogen Fuel Cell electric vehicles using GREEN Hydrogen.

Not to mention children in the Congo mining rare earth minerals at gunpoint to give the warm and fuzzies to smug, chardonnay socialists skiting about their EV at the polo match

You have been ignored because you are wrong/delusional. You clearly have not experience or insight. HFCEV have had their very limited day. HFCEV would use much more electrify than full BEV and be much more costly for the vehicles and infrastructure

A small foretaste of what is to come as the “real action on climate change” rhetoric meets reality.

The real fun and games will start when Canberrans who’ve drunk the Kool-aid discover that we don’t, in fact, run on 100% renewables 24/7 and that a “great big battery” which stores, at best, half the output of an inter-state coal-fired power station for one hour is not much use when the power station has been demolished and it’s a windless night across eastern Australia.

No, it’s not like that at all.

Those who think renewables won’t replace fossil fuels perfectly reliably in the next few decades have drunk more than enough Kool-Aid for everyone.

Chewy14. Wind, solar and batteries is not the answer, especially when Airbus Albo is bringing in a million more mouths to feed in the next couple of years

Futureproof,
Glad I didn’t say they were the sole answer then aren’t I?

ChrisinTurner2:57 pm 17 May 23

Unfortunately this article doesn’t address issues such as fast chargers versus slow chargers. Most EVs in Canberra are probably only using slow chargers at home.

Victor Bilow2:54 pm 17 May 23

Norway has the answer! smaller population, (About Sydney’s population) shorter distance to travel and surplus Hydro power.
At the beginning of 2021, there were 1 681 hydropower plants in Norway, with a combined installed capacity of 33 055 MW. In a normal year, the Norwegian hydropower plants produce 136.4 TWh, which is 90 % of Norway’s total power production.
The current ACT government could not plan their way out of a paper bag.
Just take a look around you.

Good luck with hydro around this big country. The Greens will knock back any new dams. Meanwhile, the population expands

There’s a couple of elephants in the room:

1. people will want their own charging device because any other way (eg communal charging) means that you could get your booking at 2:00 am or, worse, you get your booking and the car ahead of you has its owners nowhere to be found because it’s the middle of the night and they’ve (rightly) gone to bed;
2. there’s a big issue around retro-fitting to relatively new developments. I know of one development where the EC rep actually put it on their Facebook page that people should not have purchased EVs expecting to charge at home (ie in the basement where they park their car). That same body corporate is fining people if they plug into a power point in the basement, because there’s no chargers and they’re not allowed to install any, and there are no moves afoot to do so.

So much for governments, the world over, moving towards EVs — not if you live in Canberra and live in an apartment!

Let’s ask the Norwegians how they’re doing, what’s worked, what hasn’t, what they would do differently. They’re a good decade ahead of Australia, and are already at 80% of new car sales being EVs. I’m very confident they will know the issue and the solutions. None of what we face is new, it’s just new for us.

@riccardo
Unfortunately, riccardo, we can’t use Norway as a valid example.

Norwegian power production is almost 100% renewable and emission free. So any facts and data we can draw from their experience, wouldn’t be acceptable to the fossil-fuel-championing denialists.

Their experience of charging needs, locations and styles is quite applicable to Australia. Granted, their source of electricity is different.

Capital Retro5:40 pm 17 May 23

92% of Norway’s renewable electricity comes from hydro.

Norway also exports huge quantities of gas and oil – like Australia they prefer to unleash their emissions off shore.

Just saying.

JustSaying,
Whilst Norway’s roll out of EVs is definitely applicable to provide lessons for the Australian situation, their electricity production from hydropower is much less relevant, taking advantage of specific local conditions that dont exist here.

Also probably not the best example to mention “fossil fuels” around, considering the amount of their economic wealth that has been driven from oil and gas exports.

Not The Mama10:19 pm 17 May 23

Gasoline fires are nothing like Li Ion battery fires. Firefighters have not figured out how to effectively stop battery fires and the fumes are extremely dangerous. When the fires do eventually die they leave untold environmental damage around the area. 1 in 5 new cars are Li Ion battery EVs but the total number of EVs is still small. As the proportion of EVs on the road grows well see more and more of these fires.

Not The Mama10:24 pm 17 May 23

You can’t compare: Norway is much more densely populated than Australia, the land surface area is much smaller, so there are shorter distances between destinations, and it has 5 times the amount of water (so hydro electricity is a no-brainer).

And where does Norway get the capital to invest in renewable energy for their country? From oil/petrochemical exports. Sanctimonious hypocrites!

devils_advocate9:05 am 17 May 23

The electrical load is the least of the problems. The fire safety risks for class B buildings (basement) are far more significant. Surprised the strata manager didn’t call this out.

They create significantly greater cost for new builds that are required to comply with the ACT fire brigades new special hazard assessments, and it’s very unclear whether existing developments can be brought up to meet the additional fire hazard risks posed by EVs simply parking in the basement (not even charging)

TruthinMedia8:00 am 17 May 23

The other side of this thoughtful piece is that to comply with the ACT Labour Government’s too aggressive time frame is that buildings, houses etc will be forced to install their end of the infrastructure without the grid catching up and everyone’s charging will be throttled by load management software that stops you at say 50% of a full charge, say goodbye to your trip to the coast tomorrow, or Yass for your child’s away soccer game or Goulburn for that matter. Throttling has to occur in buildings even if the grid is up to scratch if their building power management and distribution can’t handle 100 EVs all wanting to charge overnight. By all means promote and support EV take up but mandates and aggressive timeframes will disadvantage many (most) in the community. EV Ready is just a slogan for decades to come. I reckon the Libs are biding their time until closer to 20230/2035 where an opposing view will be an election winner for them.
