The manufacturers of street lights now offer a charge point in their latest products.
Today in Adelaide is a prime charging day. The sun is out and the car is set to extract no more than 18A from the HPWC (3x6A 3 phase). Solar all the way.
I don't think the HPWC comes with model 3s. I have an Ex Demo S which did come with one but that is likely an exception. The problem currently with 3 phase charging with the UMC is that the adapters are as expensive as a HPWC, so I'd go the HPWC and then keep the UMC for charging at 10A single phase when on the road.
Even with a HPWC, 16A 3 phase is likely ideal for a Model 3, I don't think it can charge much quicker than that, and you'd be filling an SR+ in about 3-4 hours.
The Model 3 will only draw up to 16A 3-phase, even if connected to a 32A 3-phase station. The other problem is that the Gen2 Mobile Connector provided with the European Model 3's does not have an adapter available today for 3-phase. So, it is unknown whether that version supports 3-phase at all.
Yeah it does, Tesla UMC Adapter
If you get that adapter (which they can sell in Australia) you need to buy or make a pigtail to connect it to an Australian 3 phase plug (either 16A or 32A, noting the charger will draw a max of 16A).
That adapter is only suitable for V1 UMC not the V2 UMC.
Well, I only have single phase in my house, so will be limited to that. I do have 80A main fuse and a 32A fuse going to the kitchen, so I assumed, I could get a 32A to garage also, but if we are limited to 15A, then that will work also. If they do provide HPWC, then that would be preferable, however even 15A will need a sparky to pull it from main power box so the install cost would most likely be similar to 15A socket or HPWC.
Single Phase 32A is only really suitable for a HPWC, the UMC would be limited to 16A single phase or ~3.7kW. You'd also need to buy or make an adapter to convince the UMC its to run at 16A not 10A.
A 32A HPWC works out to around 7.5kW, that can take an SR+ from 20-80% in under 5 hours or an LR from 20-80% in under 7 hours.
The Australian standard have introduced a guidance annex for EV charging. One of the things that includes is recommendations for a type A RCD dedicated for each HPWC. That said a single pole RCD is likely only a minor part of the cost, the labour is generally the most expensive part. While it is not yet a mandatory part of the wiring rules, make sure your sparkie is familiar with it.
Actually this is not quite correct.
The UMC can do a maximum of 16A, and it can triple that using the 3 phase tail. So you can get a total of 48A @ 240V, which is about 11.5 kW. About 55kph.
I have this set up and have used it at showgrounds on rural road trips.
A 3rd party EVSE can up this to 32A per phase, but modern Teslas can only handle 24A per phase. The older dual charger cars could take the full 32A.
@Priit and @Munka There are also older HPWCs you can buy 2nd hand that only do single phase, but can take 40A.
I have a 3 x 32A HPWC at home, and a 1 x 40A HPWC at my parents' place up north.
For home charging a new HPWC running 1 x 32A is plenty though.
They might, and this is an example of where Government policy settings can make a real difference by removing barriers to EV adoption. In this case, State governments could amend their Strata Title Acts giving apartment owners the right to install a home charging solution in their designated parking space without requiring the permission of the Owners Corporation.
Not quite that simple as many buildings simply dont have the infrastructure - the transformer and primary cabling may simply not be up to the additional capacity of mass adoption. I know with the apartment buildings I’ve been involved with developers suck every ounce of un-needed materials out so that profits increase. Having said that, if the solutin was a 240v plug in then the capacity may exist, but a few hundred cables running from the metering may be a space challenge.
In the Australian LEAF forum some have reported using modified Mennekes sockets to J1772 plugs and using Tesla destination chargers successfully. Telsa DCs that are not set to “legacy” mode won’t work, but it seems that is the default setting. There are ready-made adaptors obtainable on the net.
I was reading about various clubs in Europe (mainly Eastern Europe) that are using HPWCs for non-Teslas.
I think at this stage all DCs should really be in 'legacy' mode to allow any car to charge. We need more EVs, whatever brand.
And if upgrades are required and the owner is willing to pay for it, then they should still have the right. All electrical installations have to comply with Australian Standards and be signed off, so that is not a risk here.
If the upgrade required is substantial then there’s a financial barrier but at least it’s not a policy one. The owner might be able to get other EV owners (or other forward-looking residents) in the complex to share the cost, or of course as a last resort take it to the OC and get everyone to pay a share.
But the bottom line is, if someone wants to do it, and has the means to do it, then no bloody-minded OC should have the power to stop them.
I travelled over easter from Sydney-Nagambie-Sydney. On the way down there were 3 Teslas at Goulburn, 2 at Gundagai then 3 at Wodonga. On the way back 2 at Wodonga, 2 at Gundagai and only mine at Goulburn, so was much better than I expected. But once the 3 is here I expect most to be pretty full on holiday weekends
I drove Melbourne to Sydney on Thursday night, in heavy Easter traffic.
Euroa: 1 other car
Albury: 0 other cars
Gundagai: 0 other cars
Goulburn: 1 other car
the app tells you the availability of nearby superchargers.
Thats whyntesla are focussed on increasing charge times as it gets better turnover at superchargers, and therefore less of them are required. The idle fees remove any temptation to stay beyond your welcome.
