Do you have the numbers or can you guess how many times per day is a DCFC used?
Are the figures available for each of the chargers on the WA electric highway? Is there a contact in the RAC who could/would provide this info?
How many EV owners, that could use the chargers, are there in south west WA? Are they all aware that the chargers are in place?
These numbers would help with a decision to install DCFCs along other highways.

I have some usage data which may help
For most of the DC charging stations I only have around 5 days worth of data - and half of those stations were commissioned at the start of those 5 days so it's hard to draw too many conclusions from those.
For the West Perth and Mandurah stations I have 14 days worth of data, which is a bit more useful.
West Perth sees between 3 and 4 charging sessions a day, charging an average of 9.7kWh per session, or 35kWh per day About 55% of these charging sessions are Nissan Leaf; around 20% each for Tesla and i-MiEV, with BMW i3 rounding up the last 5% or so.
Mandurah (about 70km South of the Perth CBD) sees about 2 charging sessions a day, an average of 10.3kWh per session and 20kWh per day. 60% Leaf; 20% Tesla; 20% i-MiEV
The others (bearing in mind the shorter reporting period) see between 1 and 2 charges per day; about equally split between Leaf/Tesla/i-MiEV.
Bear in mind that before the Harvey station was commissioned it was difficult for Perth based Leafs and i-MiEVs to make it beyond Mandurah. g4qber's 80km range i-MiEV still had to make an intermediate stop to make Mandurah->Harvey but for a Leaf or slightly less used i-MiEV it should be easier now. That means it's likely the other stations are seeing a great deal more use now, unfortunately we don't have access to any recent data. I'm working on it.
I've seen 36 unique RFID cards used over the reporting period. I don't know how many EVs there are in WA, but I assume most would know about the Electric Highway by now.

Absolutely great information. Even with this small sample the numbers for (mainly) Perth based EVs tells me a lot about current and future usage. Also high on my wanna know list is the up time. Again, it is early days, but every hour that a charger is not working is a very serious negative to someone relying on it being operational. What brand are they? Maybe I can get up time info from the manufacturer and maybe not:-(.

Waroona was locked last weekend. Best to possibly bypass Harvey n charge at the crooked carrot cafe to be sure

I am visiting WA from my base in SE Queensland. I have left my LEAF with my daughter Julia to use while I am away for three months.
I am currently in Nannup and just had a good long look at the fast charger. I applaud the person or persons responsible for the initial concept and seeing it through to getting the parties together to drive it to completion. I am certainty further invigorated to push for some fast chargers for the SE Queensland area.

RAC HQ was dead 28 Dec Diode replaced yesterday 31 Dec. Same diode that died before. Working now. Reecho was charging 2010 imiev. BMW's CCS had to be coaxed to work, had to do Big Red Button (BRB) reset a few times. Reecho got a CCS error though imiev uses CHAdeMO. Hopefully firmware update in future will solve this issue.

Is it still free to use? According to the RAC it's free only up to 31 Dec.

Flood of start transaction messages with Uwa Veefil. So much so that I couldn't tag off cos unit was too busy sending those messages Veefil is like tesla/Apple Looks good , costs more , liquid cooling Circontrol is like leaf/pc Cheaper , air cooled , function over form Attachments:

I think you mean the ABB/Schneider units are the apple equivalent. Veefil is very cheap in comparison.

It logs a start message every a few seconds! It looks more like a bug or communication flaws.

This log shows boot notification The location of Unit has 1 bar mobile reception. Used to get full page of boot notification messages. There is also interaction with Bosch. Uwa will be monitoring the unit themselves in future. Attachments:

Two important tips to those who own 2012 Leaf that has lost 1 bar and about to use RAC electric highway: TIP #1:Charge to at least 90% prior making Mandurah - Harvey journey if you want to stick to the speed limit (or vice versa). One fast charge only charge to 80%. Once finished, unplug and recharge (or move to the slow charge to make way for others). From my experience just the weekend past, from logging on Nissan Connect: Mandurah - Harvey: 72.5km using 12kWh (0.17kWh/km). There was strong Easterly wind at the time. Aircond set to 23C with 30-ish Celcius outside. Traffic was very light, so no 'draft' effect for the whole journey. Harvey - Mandurah: 72.6km using 11.3kWh (0.16kWh.km). Wind was pretty flat. Aircond set to 23C with close to 30C outside. Traffic was very light, so no 'draft' effect for the whole journey. FYI, my battery (from LeafSpy) SOH is 83%. This means, I practically only have 12kWh usable window (24kWh x 83% x 60%) if only charged to 80%. The 60% is due to low batt warning at 20% and top end at 80%. If I only charge to 'one click' (i.e. 80%), then depending on the wind, I may not be able to make it (My first trip was charged to 90% and the low batt warning came up prior Harvey). The wind effect is quite significant! Other journey is irrelevant, i.e. shorter than Mandurah - Harvey. PS: the actual figure above is pretty damn close to the graph posted by user duncan here. TIP #2:Do NOT rely solely on the in-built GPS especially when you haven't updated your maps yet. I did this and one particular trip resulting twice the distance.

Augusta finally working with i3 Clicked CCS microswitch a lot of times. Only taken 6 months
Margaret river DC dead. Fixing Monday. Mandurah CCS still to be replaced. Busselton CCS needs coaxing to work.

It's a different one each time, and although it's nice to blame the Tesla the reality is these chargers don't appear to be able to handle sustained 120A charging for more than 10 minutes in WA summer temperatures. An i3 could easily do the same, but we have many more Teslas using these chargers than we do i3s We believe we've identified the design flaw leading to these diodes heating up more than they should and have been working with circontrol on a permanent fix.

In the short term, lets hope they can de-rate the charger to 110A (or lower) to prevent complete failure.

Yes I'm in the process of visiting each site to turn down the power to 80A (and am putting pressure on Circontrol for a proper fix because this is ridiculous) Also installing SIM cards so we can monitor the temperatures etc. Tesla charging at 120A (before we turned the power down)
