I searched around and didn't find anyone that's calculated the cost to recharge the PIP. I took one of my electric bills and added an extra 4.4 kWh, the max charge capacity. I calculated an extra 20 cents Delivery charge and 32 cents Supply Charge. So that's 52 cents per charge and that's rounding up. So if a gallon of gas is $3.50 and if the PIP gets 45 mpg minimum, and if EV mode gets 15 miles per charge, then the 3 charges to go 45 miles (3 x 15) only costs 3 x 52 cents = $1.56. Less than 1/2. That's great. Has anyone else checked?
