hi Tesla owners,
I'm the president of the small HOA in San Francisco (not tesla owner myself)
and we have a new Tesla owner in the building.
Owner plugged the car on the HOA 110V outlet in the garage,
then we discovered that and are now figuring out a fair price to bill the owner.
As the car consumes 2x more than the entire HOA line, our bill tripled!
It's complicated ... could you help?
Ideally, the owner would install a separate line for the car.
We're ok with it, electricity is in the same garage as the car anyway.
Owner refuses to pay for it.
So if we share the HOA line:
1. First we have the on peak/off peak prices problem:
owner says the car is programmed to only charge off peak,
but we see a huge consumption during peak hours. ideas?
Can the UI of the car cause owners to misunderstand?
2. Also, owner does not understand why the amount reported
by the tesla app is far from the energy we clearly see is used
compared to before the car was plugged.
We're a small HOA, the power line is only used for lights and
a gas heated washing machine, so it's super predictable.
From my reading I understand the 110V is 80% efficient,
it would mean we should charge 25% more than reported by the tesla app?
Or should we use a power meter plug to measure?
(any links to a good reliable cheap smart meter that can handle that wattage?)
here's our proposal to the owner, what do you think?:
- ok for charging you off-peak rates, but we have to see
the on-peak usage go back to normal, because right now
it's much higher (x1.7) than before so you're probably charging at all hours.
- we can take your app screenshots as reference,
but it reports the energy charged in your battery,
not the energy consumed and paid by the HOA.
We need to multiply that by x1.25
that means in PG&E rates x1.25:
0.475$ in low season and 0.5375$ in high season.
or you buy a power meter plug, use it as reference
and you pay 0.38$ in low season and 0.43$ in high season.
Currently owners agrees to pay 32c and thinks
we're trying to take advantage of the situation
because it's far from what the tesla app shows.
Second problem is a level 2 charger:
Our building has an old grid, it's 110V only.
Owner would like us to upgrade the grid to plug a level 2 charger.
But the HOA does not need to upgrade yet.
Sure electricity usage is increasing as people add appliances,
but we're likely good for many many years.
When and if it happens, how much should the owner pay for the upgrade?
thanks for your advices
