Have some data now that the car finished the charge. This is from an 80% fill to an 80% fill and driving 43 miles in between. The ChargePoint Flex delivered 17.49 kWh. Lucid app said it received 15. Car trip computer said it had consumed 16 kWh since the last charge and 14kWh while driving. The Lucid App doesn’t go into decimal points so it lost somewhere between 1.49 and 2.49 kWh during the charge or between 8.5% and 14.2% loss during charging. Large error bars, but 10% seems to be about right. My cost of electricity at the current TOU was $1.82 for those 17.49 kWh. I drove 43 miles between fills so the cost per mile driven was 4.2 cents. Even with the energy losses, much better than an ICE in CA.
For driving efficiencies (again large error bars since I only have a small amount of data from one data point). Car trip computer said I averaged 3.0 miles per KWh. 43/3.0 = 14.33. Car computer says 14 so that calculation is reasonable. Since last charge says 2.7 miles per kWh. 43/2.7 = 15.9. car says 16 so reasonable. Charge received 15 kWh per the app, so from that, 43 miles / 15 kWh = 2.87 miles per kWh received. Full battery would have driven 321 miles , or about 62% of the reported range. Take that with a very SMALL grain of salt. At this point it is just weak data with only 43 miles of spirited driving and much time sitting in the car with the power on programming different things.
For ACTUAL efficiency like I would calculate for an ICE, miles driven / energy delivered, 43 miles / 17.49 kWh = 2.49 miles per kWh delivered to the car. One can’t use this number to calculate range on a full charge, but is useful in comparing the EV efficiency in miles per kWh to an ICE in miles per gallon. it takes all the charging losses into account.
Again, one data point with very few miles and kW in the calculation so error bars are huge at this point.
As an aside, Lucid said the charge was complete, but ChargePoint was still ‘filling‘ the battery. The Lucid app said it was done and the charging port lights indicated as such. I had to stop the ChargePoint. The cable remains locked in the port even after I stopped the charge and until I wake the car which was new to me. I have always been able to remove the cable from the Leaf when the charge was done. Is there a setting that one can toggle in the car? I know the Leaf will allow you to lock the cable or not in the car software. Not aur3 if Lucid has that functionality.
and as for a “red light’ on the ChargePoint. No, everything was normal.
