The range test (road test) is the
only way to determine actual capacity right after a BMS reset
Charging tests also work, and are arguably the simpler method. You just need a metered charger, and to be aware of ~ 12% charging losses. I presume it is also easier to convince a seller to let their car be charged instead of driven 50 - 100 miles
I like using public L2 ChargePoint at 6 - 7 kW, and add 50% SoC. Total usable battery capacity in that case would be
kWh_reported * 0.88 * 2
So e.g.,
If it took 10 kWh to raise the SoC 50% the usable battery capacity would be
10*0.88*2 = 17.6 kWh
