I now understand that it's used to calculate relative capacity, but I think a gross discrepancy in AH vs bars is the easiest way for a newbie to determine whether or not the BMS was reset, while test driving a used Leaf. So the best number we can give the OP is an AH range that is valid for 12 capacity bars, and below which a reset is indicated. Would that lowest number be 57.0? 56.5?
Presently my Leaf with 44K miles has 51.3 Ahrs when fully charged (SOC=100%) and 12 bars. The first bar
now drops at about 48 - 49 Ahrs while driving. Since new (12/1/13) no special charging approach has been
used, i.e. 100% during 5 week days and 2 -3 QCs per week. The Ahrs were not evaluated when delivered until
about 4K miles (61 Ahrs). I assume, as SageBrush mentions, that when it was delivered to the dealer from
the factory it had about 65 Ahrs (65A X 370V = 24kWhrs).
While driving, the Ahrs are never lower than 18 - 19 Ahrs the result of trip planning and the use of QCs or L2
access via my customers using the Leaf EVSE via multiple EVSE plug adapters. Based on my typical driving
(~ 2 miles per Ahr), I continually calculate my range and basically never use the GOM. So now with about
51 Ahrs (SOC = 100%) minus 19 (lowest allowed Ahrs), my present expected/allowed range is about 60 miles,
requiring prior knowledge of QC locations. LeadDD is continually connected to monitor the Ahrs during
driving. A BT dongle is carried in the glovebox to utilize LeafSpy Pro for detailed diagnostics, e.g. read & reset
fault codes if a problem occurs, e.g. a QC fails to initiate charging.
Leaf SL MY 9/13: 65K miles, 50 Ahrs, 5.2 miles/kWh (average), L2 charges to 100% > 1000, max battery temp < 95F, min discharge point > 20 Ahrs
