It does need to be more than the domestic supply charge or the same people will keep driving from their house to use it "because it is cheaper".

It does need to be more than the domestic supply charge or the same people will keep driving from their house to use it "because it is cheaper".
Based on the NRMA survey I recently completed, it appears that they will offer different membership packages with a monthly fee and different charging prices according to which plan you are on, rarely, regularly or frequent.
Yep totally agree. Weeding out the cheapos that do have access to home charging yet congest the AC chargers and make it difficult for those that would actually pay to use them.
My son will probably be in that boat, no access to home charging. That is if he goes ahead with the purchase of the BYD he has on order That journey is part of another long long story. He more than likely will purchase a M3 or wait for something better next year as he is getting quickly turned off by the brand representation in Oz.
Off-peak time of use tariff is less than 20 c/kWh, but if you can swing it, using excess solar on the weekend is the way to go. The opportunity cost of the solar feed in tariff is even less, unless you're a Queenslander getting 44 c/kWh feed in tariff until 2028.
When I first got solar in 2019 my FIT was 20c. It’s now 5c.
So I try very hard to export as little as possible by sending as much excess solar I can to my EVs. Unfortunately since Nissan killed their telematics system in 2021 it’s not possible to remotely start or stop charging on the LEAF
I have the same issue on my Zoe. However, I use my OpenEVSE which is on WiFi and accessible from anywhere via my mobile phone or a PC and I can start, stop, change the current, set timers and kwhr limits plus engage the tracking mode for "only charge with excess solar".
The in-built charging control capabilities of the LEAF are very primitive. How does OpenEVSE control the charge rate of the Zoe? Does it present itself as, say, a 7.2 kW supply, but then just vary the delivered power in accordance with excess solar or other settings? If the car is expecting 7.2 kW but doesn’t get it, no warnings are triggered?
The Zoe is similar to the LEAF.
In the OpenEVSE, minimum charge rate is 6A and you can set the max in 1 amp increments up to 32A. When set in solar mode, the OpenEVSE tracks the excess solar (via MQTT in my case but it has multiple inputs possible) then it adjusts the charge rate between 6 and whatever max you select. You can also set a start time, stop time, duration or max kwhrs. The only thing I cannot access is the Zoe's SOC. Also, you can set the response time and smoothing for the excess solar to cater for the response time of the car, clouds et al. In my case, the Tesla responds more quickly to changing the Pilot signal than does the Zoe. The GUI of the OpenEVSE gives kwhrs delivered and time. Here are a couple of screenshots. Mine is an early version and later ones have extra capabilities.

Those with sharp eyes might wonder why the mains voltage is set to 77. I set it to 1/3rd when single phase charging because the my OpenEVSE is a three phase one. When "out and about" it defaults to 230V. One day I'll change the firmware so Type 1 charging (US 120V) is single phase 230V and Type 2 remains as now, three phase.
Sorry this has drifted away from NRMA charging! Just to finish off my disruption, here is a graph of my place yesterday. Yellow is Solar incoming, blue is power used in the house. It was a complicated day with breadmakers, dishwasher, kettles boiled, oven. Sharp spikes are a water bed and a fridge. Excess solar goes to the car as first priority, followed by any extra to a small LFP bank and any left after that to a big LFP bank. I had the OpenEVSE (on the Tesla) set to 12A max so that there was extra available above the car charging. The bit of yellow on the right (exported to the grid) happened because the Tesla reached 80% and both battery banks filled up.

NRMA adding batteries at some locations NRMA welcomes NSW Government funding for EV charging network expansion

NSW funded Tesla superchargers, all 32 sites, will be open to all EVs and must include at least one Chademo connection per site.
As reported by NSW government department employees on Tesla Tom's live chat tonight.
Will be interesting how they achieve Chademo support as I think that will be a world first. Maybe just a third party charger included on site but I don't feel that is the typical Tesla way. Could we see a supercharger with a second cable that supports Chademo? Tesla already know how to have their cars talk Chademo so I wonder if they will just make their supercharger talk Chademo.

NRMA has added a comment to the Plugshare reference for the notorious Mittagong charger.
It's down yet again, and they now seem to be saying that they are doing a full unit replacement with a newer model (maybe the 75kw?) and trying to add more stalls.

Would have been sensible to make that decision 12 months ago.
The need is somewhat diminished with Evie Sutton Forest now open, and BP Marulan (both sides) coming along nicely.
Other than of course the induced demand by the Freebie factor, which is one of NRMAs own making.

The replacement of the notorious Tritium charger at Mittagong is now complete.
New one is a different model, but unfortunately still a Tritium. It’s got a paywave terminal on the front and appears to support simultaneous charging.
So in theory, a Nissan leaf can come in from the back and charge at the same time as a CCS car is using it.

The previous one did run fine for more than a year between 13 April 2021 and 23 July 2022, with it being very busy for most of that time.
