I posted this on the MS forum too. I am trying to reconcile the actual cost to Tesla for the Free Supercharging. After doing the math, I was amazed at the potential costs to TSLA. Here is my post:
Has anyone ever heard of the old adage, "A dollar a day, a million days, a million Dollars"? One day, years ago, I was thinking about saving a million dollars. So I thought to myself, how much would I have to save, each day, to accumulate $1,000,000.00. So I got out my calculator. I figured we live about 84 years. First, I figured to save from day one. I used 365.25 (Can't forget leap year) multiplied by 84. After adding it up, I was surprised to see that we only live 30,681 days. Needless to say, I had to put more away than a dollar each day. I write this, because when it comes to the Free supercharging, the math reminds me of the old adage.
Case in point:
If a Tesla is used as a Taxi/Uber/Lift/Business use between LA and Las Vegas for one round trip each day, then that car would travel about 570 miles each day, or 208,000 miles each year. The annual cost of the Electricity alone for this car would be approximately $8,322.00. This assumes $ .04 per mile electricity cost. With a lifetime warranty on the drive-train and 8 year warranty on the battery, the fuel cost expense to Tesla, on this one particular taxi (Which would only be driven 9 Hours a day) is a minimum of $66,576.00 (For 8 Years). That expense is just for electricity. It does not include warranties, battery replacements, drive-train replacements or the costs to operate a supercharger. Hey, If I were a taxi driver, I'd want that deal too!
Since most Superchargers do not operate on Solar or wind, and TSLA has to buy the electricity from local suppliers, can these number be correct? If they are, Tesla could potentially lose more than 100% of the value of the sale over 10 years. Since these high mileage vehicles are more prone to wear & tear, I would assume that they encounter more battery and/or drive-train replacements.
I welcome comments. I'm not trying to put TSLA down, just want to confirm if this could happen???
