Hi all - have been happily driving my MS for a few weeks now and wanted to share the realities for those who don’t have access to home charging. I live in a condo so I utilize chargepoint stations available to me in my building as well as the Tesla supercharger network where I can.
I have found EV costs to be higher than ICE on a weekly basis.
For comparison I came from an ICE sesan which gave me 35 mpg on my daily commute of 100 miles. At $4/gallon that’s only $11.43 in gas.
In 1 week, I will spend ~$75 on chargepoint alone.
Just a word of caution for those that don’t have access to cheap charging solutions!
YMMV
Your data indicates that you really need to think twice about your charging process. Plugging in and sitting on a charger that charges per hour is far from an optimal solution. Look at the last 3 days, the day with the least miles are the most expensive.
You are charging at a site that is $1 per hour for 4 hours, then $3 hour afterwards. You can probably get the 100 miles in less than 4 hours. Unplugging at lunch would definitely help, plus since it doesn't look that you really need it, unplugging at lunch would let others use the spot. Having a car plugged in, not charging, is just as bad as the spot being ICE'd and it's also why ChargePoint dramatically raises their price after 4 hours. You should be getting pinged when charging is complete.
If you were to unplug at lunch and/or swap out with supercharging once or twice a week, then your costs will plummet.
I would check some of your data (or maybe it is me that is reading it wrong) 40 minutes at $2.33 seems to be higher than it is supposed to be. And 8:42 hours seems lower than what it supposed to be.
So ,yes, ChargePoint isn't cheap. And yes, you have the opportunity to slash your costs and be a considerate public charger.
At 100 miles per day, you are using about 25kWHs. Those ChargePoint plugs seem to support 6.6 kW, which means that you should be able to top off in 3.8 hours and therefore cost $4/day.
If you paid for supercharger, then you would pat $0.26 per kWH or $6.50 per day.
So, it is indeed possible to pay less than 1/3 the cost of your ICE.
