Hi, I recently purchased a 2024 MG4 Excite 51 and I'm very happy with it so far.
My question is, does somebody know roughly the cost of a full charge at home with the slow charger on a standard power point in WA? I do have solar panels, so I'll take that into account after I find out the rough cost of a full charge. Just doing some numbers on how much I will be saving on fuel per charge.
Thanks
High how are you
Cruising, how high are you?
Haha yeh
Yes
Nice.
Full charge would be your battery capacity x per kwh rate
Stop it with your complex mathematicals.
Calculations in cents. Cheers.
Maths makes op incensed. Cheers
+5~10% because there is an efficiency loss in the process.
I swear to god… the new Tesla…
What time of day are you charging it? What is your rate for that time of day?
It would roughly be: (51kWh capacity x 1.1 to allow for losses) x kWh electricity rate
(51 x 1.1) x $0.08/kWh = $4.49
Who is paying 8c/kWh for electricity?
Me, between 12am and 6am I pay $0.08/kWh
Between 11am and 2pm, I pay $0.00.
I'm guessing you are on Ovo? Have your rates (or anyone elses) sky rocketed with Ovo. When I signed up I thought I was getting a really good deal - nek minute.
Peak unit rate: 46.31c/kWh
Solar sponge: 28.6c/kWh
Off-peak unit rate: 33.44c/kWh
Solar feed-in tariff: 2c/kWh
Supply charge: 156.2c/day
@jason101: It’s about on par with all the other suppliers in this area… I did get the OVO shafting raise though, where they sucker you in with cheap rates and then give you some sob story about how prices have gone up and about 2 or 3 weeks in I got slapped with a price rise.
All of the other suppliers in my area were way up over $0.22/kWh for off peak and gave no free time in the middle of the day, so it still works out a lot cheaper that the alternatives if you spread your loads out during these times.
Supply Charge $1.166/day
EV Charging $0.0799997/kWh
Usage - Off Peak $0.3498/kWh
Usage - Super Off Peak $0.00000/kWh
Usage - Peak $0.5995/kWh
Solar FiT $0.03/kWh
@pegaxs: 60c/kwh peak. Wow!
The thing about this country is when one company sees a rip off the other ones follows. I am all for renewables but the renewables is cheaper is such a lie, at least at the grid level.
<facepalm>
Old enough to buy a car, can't figure out how much it costs to charge the car.
51kW battery assuming 10% reserved/not charging from fully flat = ~46kW of charge, with 10% efficiency loss in the process = 51kW billed to you, assuming standard WA inc GST tariff @ $0.315823 = $16.11 for a 'full' charge.
Then assuming a 15% over quote on standard range by the testing authorities (given it is rare to achieve the same rates out of their testing conditions) = around 250km of range (not fully depleting the battery as described above) at a cost of $6.44 per 100km, or roughly equivalent to 3.9L of petrol per 100km if a fill is costing you $1.65 per L (about the going rate on Tuesdays at my local servo). Roughly equivalent to running a hybrid Corolla.
51 * ((e2ix + e-2ix )/4 + e2ln(sin(x)) + 1/2) * cost per kwh
Excite
Yeah right
They spelt Ignite wrong*
*says jv
This one simple trick makes jv hot under the collar.
jv = jalopy vehicle
If you are charging with solar all you are losing in the feed in tariff? How much is it in WA?
Tesla owners would tell you they charge for free from their solar (I always ask them how to get free solar on my roof but they can never answer that question)
You only have a problem if you charge it at peak rates.
Goven the feed in tariff is so low, by using your own solar you are much better off than paying for electricity from somewhere else. Sure, its not free, but its as close as anything else is to free. Nothing is totally free, theres always some form of cost.
Makes me wonder with your genius words why they haven't solved world hunger.
If they start throttling solar feed in because the grid cant use it, youre better off putting it in your car. Thats free, because it would otherwise be wasted. Feed in is 6-10c/kwh. Buying electricity is twice that in off peak or 4-5 times in peak or at a fast charger.
Hunger solved.

That is if you are at home and they give you notice to plug in.
What is this OzbargainGPT?
So many variables that can affect the energy cost:
-Kms driven per week
-Day time consumption of other electrical consumers
-Whether the car is parked at home during the day or not
-What even is "one full charge" and is it even comparable to "one full tank" (Usually one fills their petrol tank when 1/4 empty or when the petrol is cheap - a 'full' or 3/4 tank would have a different range to a full or 3/4 battery)
Better off to convert both petrol and energy examples to a cents per km metric then compare that way.
PS. I didn't know WA electricity tarrif was so expensive.
roughly the cost of a full charge
Its like asking what the cost of a full tank of fuel is…..
Was the tank 3/4 full or 1/4 full or empty?
If you asked someone how many litres to fill their tank, they wouldnt assume its already 3/4 full. A full tank is capacity from empty.
I never fill my ICE tank from empty.
My EV gets charged each day, it is never EMPTY. Some days it only needs a few kWh, some days its far more. Some days it needs none.
I normally fill my diesel car from near empty becasue its a pain and i need to go out of my way to do so.
Im sure if i had an EV id probably charge it when convenient, not run it to ner empty all the time.
As above somewhere, youd be better off working out a cost per km. Although with an EV it changes a fair bit based on when/where you charge. Solar or off peak at home is best. Super fast chargers arent cheap.
Im sure if i had an EV id probably charge it when convenient, not run it to ner empty all the time.
But you don't treat EVs like your ICE if you have home charging, it isn't like filling up your ICE having to go out of your way to find a charger and fill up.
I rarely think about charging, I come home, plug it in and when we have excess solar it charges the car. 10 seconds to plug it in, 10 seconds to unplug it. The 'tank' is always full as such, so just jump in and drive.
If you want to know the rough cost of a full charge, sure its battery kWh x kwh cost.
But then are you charging to 80% and only going down to 10%? If so then, its battery kWh x 0.7 x kwh cost
But you don't treat EVs like your ICE if you have home charging, it isn't like filling up your ICE
Thats what i meant. Plug in at home, its convenient. Or if theres any free chargers where im going, use them.
