Those Tela screenshots are impressive. Good information and well laid out to let you know how the car and your driving habits are affecting your efficiency.
Have found Tesla charging stats useful for % energy consumed at home vs. other vs. superchargers. It can even account for TOU rates. Cost component has not been particularly useful on our end, though. The main problem is that there is no way to account for home solar PV and the very affordable consumption of that.
One would think so, but the number of people camped at the local Home Depot parking lot supercharger every evening says that some prefer to charge just before the long commute home or just before reaching home. But seriously, the overnight charging works fine as long as the commute is short enough and the car is efficient enough to allow you to replace the energy used overnight. A huge percentage of the plug in community travel less than 30 miles a day and can top off the battery in a few hours even on a $150 level 1 or level 2 charger. Anecdote: in order to spur EV sales, California was offering large subsidies to people who leased EV cars. Calif was also providing free power through public charging points. The combination was such that you could lease a Leaf for just over $2000 a year, and then get a $2000 rebate from the state. That made the 60 - 80 mile round trip to silicon valley free. When the lease was up, they turned the cars in and started over. I don't see any leafs in the neighborhood now. Like the VOLT, they seem to have fallen out of favor.
i have read here people who won't charge at home if they can find free charging. 60 large on a tesla, but they don't like paying for electrons
We used to joke about the COSTCO buffet at the sample kiosks. Free charging works best if you are also doing another chore. It depends on how you value your time. Bob Wilson
Similar, have charged a fair number of times at free charging stations, but just long enough to do shopping at the local establishments then moving on. Not really worth the time of hunting them down and squatting, but it's still a thing.
