An ex son-in-law had a wallet full  ' use one to pay the other ' , one day he was told to add up all the CC  membership & monthly account charges , shocking almost a $ thousand .

Big noting himself cost a lot.

( buys motorbike tyres from the states ).

Went for a walk & got picks of the " shopping centre EV power-bank" .

 

now I know it's " EVIE " .

There's potential for you yet. Why is the "Need Help" Bit inverted?  Nev

I have been away for a while. I am coming up to 2 years of EV ownership. As with 90% of EV owners I charge at home. The MG4 came with a granny charger. You don't get one with some brands. Tesla give you nothing now. I have used the granny charger once & that was to make sure it worked. I installed a 7kW wall charger & I get free power for 2 hours a day. I also have 8kW of solar panels so my running costs are negligible.

 

The network is better than it was 2 years ago & there are now many "Destination Chargers" at hotels & motels & these are usually free. In the 25,000km I have driven so far I have spent about $150.00 at fast chargers. As with most people I don't do many long trips. The average car owner travels to/from work each day & except for long trips on holiday etc all charging is done at home.

 

The charging process varies and the simple way is to register with each of the main suppliers. I have with Evie, Chargefox, BP, Ampol & Tesla. I have an RFID card which is registered with 3 of them. I pull up, plug in scan the card & that's it. If there is a queue it is bad etiquette to charge to 100% as the last 20% will be slow. I have not had a problem waiting long & by the time I have been to the loo & had a coffee or bite the car is ready. In the MG4 the WLTP range is 450km. At 110kmh I get around 380. After that many I am ready for a break. From Coffs to Noosa I stop once for lunch & charge top up (20-30 minutes). Admittedly this is on the main highway & chargers are everywhere. The thing is the car has a built in Satnav with a charging planner & it knows what range there is and will tell you which charger to go to & in many cases can tell you if the charger is in use or not.

 

So where are we going from here? Well CATL, the worlds largest battery manufacturer has recently announced a new battery technology that uses a combination of 2 types (lithium & sodium) to provide a range of 1500km and can get 520km of range in a 5 minute charge. That is quicker than filling a petrol tank. The new tech breakthrough is with Sodium ion technology. Of course sodium is everywhere. The sea is full of it & it is cheap.

This is now where battery & charging technology is up to. The only thing that will happen from now on is that it will get better & better. Already battery warranties are 1.5 to 2 million km or lifetime, The battery will outlast the rest of the car.

 

EV haters will continue to abound but they are being rapidly drowned out with reality & the uptake of EV ownership continues to climb (Tesla excepted due to the Musk factor). Worldwide 17 million new EVs were sold in 2024 representing a 20% increase on the previous year. The new government is not only supporting the switch to electric vehicles but also getting more home batteries installed. Since the election home battery installers have had a massive increase in orders and inquiries. The electric future is here.

Kevin, how long does it take to charge the MG4 on the granny charger? I presume that charger simply uses a standard 10A, 240V socket?

 

Is the 7kW wall charger a 3 phase unit? What did the installation of that charger cost? I'm surprised they're measured in kW, I would've thought the charger would be measured in amperage capacity.

 

Do you get lower charging costs late at night, or in the wee small hours, when power demand is normally much lower?

The granny charger that came with the car is limited to 8 Amp input or 1.84 kW and the inverter will probably provide about 1.5kW DC to the battery so to charge the 64 kWh battery from empty would take 2 1/2 days You can get 10 & 15 amp granny chargers from Ali Express  pretty cheap. The MG limit is probably due to the average idiot using a 1.5mm extension lead causing excessive heat plus leaving it coiled etc. 

 

Indeed the wallbox is rated at 32 Amps (7.4kW input single phase). 3 phase units are rated at 11 Amps or 22 Amps with 32 amps for all 3 phases. No point from my perspective as I only have single phase at home & the car inverter is also single phase. I installed it & and my sparky friend signed it off. Cost only about $100.00 for the 12 metres of 6mm TPS cable & a 40 amp RCCB. I hard wired the wallbox. It is called an EVSE (Electric Vehicle Supply Equipment) as it just supplies AC power to the car. The car inverter then charges the battery. It is configurable in 1 A increments from 6A to 32A. This can be automated via software to link in with the solar supply though I don't have that version. The EVSE is from ZJBeny & cost $550.00. The flasher version was over a grand. If I need to charge on a cloudy day I just go in to the App on my phone & limit the input amps.

 

I get free power every day from 12:00 to 14:00. This is the daytime plan from my retailer. The night time plan provides power at about 5-6C/kWh from midnight to 4:00am but the daytime plan suits me better. My last 3 power bills have been credits & I am only getting 1.14 cents/kWh for export now.

 

When i get home I just plug the car in & it will charge between 12 & 2 unless I amend it from the car app on my phone which I do from time to time.

 

Last week I did a couple of longish trips & only had 7% of battery left when I got home. I charged for an hour or so while the solar was still producing & re-started the charge the next morning at about 9 am at 20 amps & increased it to 32 amps at about 11 am then left it till the car stopped the charge at 80% & ran it's cell balancing program for about 20 minutes & it was complete by about 2:45pm.

As I drove on Tower Road, Bankstown Airport on Monday, I noticed that a couple of parking bays had EV charging units. Other than that I know nothing about them.
