The peak/off-peak hours should be accurate in the nav of your car so you can see the price (if not on the unlimited) of any nearby supercharging any time there. It seems to have gone up to .29/.58 now from .24/.48 earlier this year.Newbie here. How to get the Tesla company alert, if anyone knows, I didn't know the off-peak hour was pushed off 2 hours later. My cost was doubled, which means fewer savings for my wife's gas spending
Thanks
That's only if you ONLY supercharging at the highest rate period. Most people could get lower rate charging at home at certain hours or at supercharging at lower rate period. I think on average, it would be closer to 25c / kWhI had no idea peak Supercharging rate was that high. 48 cents per kWh is the equivalent of 12 cents per mile. Assuming ICE cars run at 30 mpg, this Supercharging rate is equivalent to a $3.6 per gallon gas price. In the early days of Covid, driving a gas car was actually cheaper.
Ok 25 cents is reasonable. Ladwp charges 20 cents so this really isn’t much more. EVGo charges much higher base rates.That's only if you ONLY supercharging at the highest rate period.

Is there a law in WI that EV charging has to be per min? It seems to me that they are converting the per kWh rate to per min. I think the bottom rate (highest) one is the beginning of the session when you are more empty so it was charging faster so you get charged a higher rate. Then at the top, the charging curve slows down so you get charged a lower rate. They are still charging you per kWh, but breaking it down into a per min curve. That's just my guess.Here in WI, they charge per min, and the rates are going as high as $1.20/min, which sounds high to me.

The time charge definitely looks different. I wonder if they are factoring the demand charge. Commercial electricity charges can factor in a demand charge for not only how many kWh you use, but also how fast you use them. I understand this is cover the electric company extra costs needs to use to hook up a high draw customer.Is there a law in WI that EV charging has to be per min?

You guessed it right. The highest (Tier4) is for charging above 180kW.Is there a law in WI that EV charging has to be per min? It seems to me that they are converting the per kWh rate to per min.

VAT in Wisconsin?I downloaded the Statement. The charging rates are based on UnitCostTier

Here is the previous rate structure... I wonder if Tesla made additional changes beyond the 11 am - 9 pm hours?They snuck another change to the hours in California. It must have happened today or yesterday. Kind of got burned on this today since I sent someone to charge my car thinking it was off peak before 11 am and after 9 pm. Turns out it’s now before 9 am and after 10 pm. A little warning would have been nice.
Hours | Supercharging Rates |
---|---|
12am – 11am | $0.29/kWh |
11am – 9pm | $0.58/kWh |
9pm – 12am | $0.29/kWh |
