How do we propose we do this? Use LeafSpy type tool?
I am confused by this apparent fix from Nissan as even the LeafSpy tool was reporting lower values and thereby implying the battery storage capacity was dropping rapidly on these 30 kWh models. Am I correct with this statement? This fix will resolve the dashboard inaccuracies but wasn't LeafSpy tapping the batteries directly and LeafSpy did not use the input from the dash?
Small point of clarification; The dashboard displays were likely accurate. Well as accurate as you can be when using invalid data I guess. The error is basically at the very foundation of the battery pack itself so EVERYTHING is potentially affected.
LEAF Spy only parrots what it sees on the bus. So any miscalculation would be passed on. The real concern is what other changes will happen with the correct calculations?
Realize it is possible that the BMS allowed the pack to charge to full speed up to 80% SOC (something ONLY the 30 kwh pack does thru out the entire industry) because of bad info it was receiving from the LBC.
So fix the info and now the BMS starts ramping down the charge at 63% SOC like the 40 kwh pack did (24 kwh pack ramped down earlier)
A possibly good analogy (any analogy requires being on the same plane of thought)
You are in Detroit, Michigan and want to navigate to 123 Baker St, Detroit, Michigan.
So you get directions from the NAV but the NAV doesn't realize its in Detroit, Kansas navigating to 123 Baker St, Detroit, Kansas. It only knows you must travel in a specific direction for a specific distance and then turn right...
