Teslascope accurately calculates costs for charging sessions by converting the vehicle's average charging rate (in KW) to kWh and then individually calculates the costs per hour.

It is important to note that the displayed kWh for each session is just the energy that made its way into your vehicle's battery and the actual total energy used often differs due to factors such as battery degradation, temperature, and using features such as the AC while charging.

The Equation

First, we must convert the vehicle's charging rate (in kW) to kWh. To do so, we find the average charging rate of each hour a charging session took place within in addition to the total minutes. If a charging session took place for 45 minutes at an average charging rate of 6kW, than we can determine that the total kWh was 4.5.

Using this, we can now select the vehicle's charging rates (plans) that have been set up by the owner and determine the cost. If the cost per kwh is $0.11, then we can assume that the finalized charging cost estimation would be $0.49.
