Tesla Superchargers definitely come in handy when taking a Model S on a long road trip, but how much time does the car need at each station? Especially if your passengers are a family with little kids, it would help to know if a stop should be just a short stop or should be a longer stop for lunch. To answer this question, I took my S to the Hawthorne Supercharger to measure how fast it charges. I intentionally depleted the battery before my arrival and recorded measurements every five minutes while it charged it to 100% full. After some curve-fitting (one way to use a Physics PhD), I determined a formula to generate a table, inspired by PADI diving tables, useful for predicting the charging rate of this Model S from one state of its battery to another. Today it's on my web site: Tesla Model S - Supercharger Table To test its utility, I used it for my family's first long-distance road trip in my S from Orange County to the SF Bay Area: Tesla Model S - First Road Trip The table was very useful because it told me that I only needed a simple 20-minute rest stop in Tejon Ranch, then an hour lunch at Harris Ranch, perfect for a couple fussy little kids. And my actual results in the field, even when our stops deviated from my original schedule, nonetheless confirmed the predictions made via this table. Now that the Tesla Supercharger network is so substantial, being able to predict needed charge time well in advance of your next long trip comes in very handy, so here it is shared with all. This chart probably applicable only to the Performance 85 Model S with 90 kW Superchargers. It would be interesting to perform the same experiment with the 85 and 60 kWh Model S and construct similar tables.
