Introductory post - Roadster Charge History Incorrect

[ShawnA]

Hi All,

My name is Shawn, I live in Southwest Michigan. My car is a 2010 Fusion Red Roaster Sport #785 delivered December
2009.

I replaced the VMS and ESS in 2015. The car was plugged in to a mobile connector 14-50 240 volts with good voltage and no breaker tripped. Across the winter I checked weekly and I saw the same thing every week "191 Ideal Miles Range."
Everything was good through the winter until the display blacked out. With service tools the VMS showed 167 miles range.
I am good with the replacement of the VMS and ESS.

My worries are what appear to be "missing" charge sessions as shown on the small display.
They show up in the diagnostic screens but are not shown to me on the small display.
I am worried that the gaps in the history shown could also represent gaps in other messages not shown.

The pictures below show the charge history display and the diagnostic display and they do not appear to match for the
same time period.

Any and all help is welcomed. Thank you!!!

What subsystem needs help? Troubleshooting? Are parts available?

Sorry for the giant pictures, Shawn

Just a guess, but the Ah of the missing sessions are basically 0 as the Roadster will wake up each day and charge IF NEEDED. I assume it started to charge and saw the battery was full and then shut down.

Hi dhrivnak,
Thank you for your reply. I would agree the "zeroes" might not show in the listing.
It seems to me that both screens are showing the same data and new entries appear on top.
They accumulate and on the driver facing screen, they are pushed down, and they fall off as the screen fills.
Comparing the top and middle pictures - None of the "durations" match for the same dates.
This is supposed to be the same data - Right?

Also, I have observed that multiple charge sessions get merged into one if the car has not moved in between.

Hi Slcasner,

Thank you for your observation.
Something is odd in that none of the screen sessions match each other by date or duration...
