Well, I'm little bit puzzle on how the billing was performed previously and how it is done now?
- When I'm charging at home, I have a Watt meter giving me the total energy used including the losses in the inboard charger (~ 5%).
- When using a
Supercharger, I assumed that I paid only the
energy passing through the plug, so after the AC to DC converter, right?
So, if I'm correct, there is a 5-10% loss which is not billed to the customer?
- If I am using HVAC, some of the energy will go to the battery (let say 50 kW) and some might be used by the HVAC (let say 1 kW, or 2%)
Will Tesla then use a different rate for the battery than the HVAC, the current rate is about $0.25?
How this will work in states where Tesla has to charge by duration and not by energy delivered?
- Or does this new mechanism apply only if you are enrolled in a
free supercharging program?
So you will not be charged for the battery and only for the HVAC?
If you had a free 1,000 miles or 1,500 km referral program (~400 kWh), you will pay then only the HVAC at each session?
Why not deduct the total energy delivered to the car, so may be you will have 2% of it used for the HVAC (about 8 kW, or 30 miles / 50 km)?
Honestly, unless you are an heavy user, the 2% of overhead for HVAC seems to be penny counting.
Note: I felt bad for people in cold weather countries who cannot use gloves when driving because of the touch screen:
Tesla doesn't provide an heated steering wheel for the Model 3, so you might have one hand with a glove but not the other,
thus forcing you using some extra HVAC, especially when parked at a Supercharger and using the touch screen.
While Tesla doesn't disconnect the HVAC on the passenger side if there is no passenger, like on the Kona?
