I think now is the right time to report my results.
Today I passed 100 000km mark (62k miles) with my 2014 EU Leaf.
104 QC sessions (doesn't actually matter, trust me) and...
93% SOH 93,7% Hx (Hx always leads, SOH follows).
Even though numbers almost went down to 91% in summer, they came back, as the
always do (same last summer), right before BMS halts the calculation (no refresh below 15*C).
So I'm stuck with that number likely for the whole winter. In summer, it constantly
jumps up and down. It usually drops if SOC is cycled between 20-80% and if it
drifts off, it returns REALLY FAST after one long QC session or one deep cycle (2,6-2,8V up to 4.14V).
3% difference (both SOH and Hx) within 100km noticed this summer.
Due to climate, 98% probability that battery is between -5C up to +35C (3-6 bars).
Always charged to 80%. Often discharged below VLBW. Rarely charged above 90%.
Immediately charging after commute ends.
Third of commutes use 15% of battery, another third 70%. (+10% for both in winter).
I do not want to hear recommendations. Results speak for themselves.
So I really lost around 2kWh of capacity. And regen availability is compromised
when battery is below +5C and SOC above 80% simultaneously (less than 25kW).
When pack was newer, regen limit usually kicked in below 0C and above 85%.
In summer (5-6 temp bars), regen is always all bubbles below 95% SOC.
Short range EVs <30kWh -- Medium range: 30-60kWh -- Long range: >60kWh
Charging: Trickle <3kW -- Normal 3-22kW -- Fast 50-100kW -- Supercharging >100kW
