Tesla Coil Posted July 20, 2020 Share Posted July 20, 2020 Quick question: do you assume that there is a linear relationship between the displayed SoC and the energy in the battery? At least for the Ioniq 28 kWh this does not seem to be the case (and unfortunately, less energy is included in the lower SoC range). Link to comment Share on other sites More sharing options...
Ecurb Posted August 9, 2021 Share Posted August 9, 2021 In general, you'd think the SoC would be directly proportional to the useable energy in the battery. But sometimes the car manufacturer "hides" some of the available energy. For example, the Tesla model Y still has over 20 miles of useable driving range even when the battery SoC displays 0%.

Ou Boet Posted August 10, 2021 Share Posted August 10, 2021 I think that what you're seeing in the IONIQ is that at lower SoC's to maintain the same power draw the current increases as voltage decreases. I've noticed that at high SoC's ABRP over estimates power used slightly and at low SoC's under estimates power used. Maybe by 5% on each end. However, it pretty accurate over a typical battery cycle of 80% to 20%. Link to comment Share on other sites More sharing options...
TomTomZoe Posted August 13, 2021 Share Posted August 13, 2021 (edited) I think using Livedata with the individual driving model should handle the nonlinear rati between SOC and Energy. Do you use live data? Edited August 13, 2021 by TomTomZoe Link to comment Share on other sites More sharing options...
