Following on from a stale old thread, I thought that I would follow on here regarding phantom top up charges. When I originally posted, I had thought that it was topping up to keep battery at set charge limit. However, today I did a solar PV topup for a couple of hours to 55% SOC. That completed at 14:57 / 55%. I then reduced the charge limit to 50% to specifically prevent these little top ups previously noticed when solar may not have covered the full power draw. So it was my surprise that at 15:31 I get a charge complete at 55% notification - oddly no associated charge start notification. It must have been quite brief as my 5 minute data logger failed to detect it at 15:30 but it draw enough to make a small blip on the 5 minute average 15:30-15:35. Double checking app and TeslaFi, charge limit was as expected 50%. So not a case of keeping battery topped up to 55%. So what's going on then? The only thing I can think of is some form of pre conditioning kicking in, but with cabin overheat controls turned off, so you might think that it wouldn't do any form of conditioning/cooling.
