That would depend on OAT. I normally see as much as 10º temp rise on a level 2 charge to full.mux wrote: ↑Wed Sep 18, 2019 10:40 amOn *just* the 40kWh battery: anything seems to heat up the battery. Looking at it wrong is potentially bad. But all jokes aside - the Leaf 40kWh will heat up under any scenario - both driving and charging - but it'll heat up by far most during QC sessions. Using the 6.6kW charger shouldn't really heat it up much, maybe a degree here and there over many hours of charging.
+1. I QC'd from 20% to 85% with pack starting at 115º F at full speed several times. Never saw a hint of a slowdown ever with one exception and since high heat was far from a possibility (first QC of the day on a 40º day) I chalked that one up to station issues.Oh yes! Absolutely, the 30kWh battery is the best battery Nissan ever made. Doesn't rapidgate, QCs up to 80%+, reasonable rate of degradation if you charge to 80% and reasonable range for everyday use. That and the air-cooled 24kWh battery in the e-nv200, that one's surprisingly excellent as well. I've seen 100 000km+ e-nv200s with 90% SoH batteries. Same chemistry, but even the slightest hint of thermal management saves that battery long-term. Unfortunately that's not an option for the Leaf, it's a completely different form factor.
I had nearly 300 QCs in 29,000 + miles and "practically" no degradation. 14 month LEAF Spy reading ahr; 82.05, SOH 100%. That pack was bulletproof.
