Re: Rapidgate on the 62 kWh Leaf Plus?

Wed May 08, 2019 7:59 am

I'm getting a 2019 40kWh LEAF on the 20th to see how it compares to an early 2018 version. There is a 50kW charger a block from my house, and another one about 30 miles away, so the plan is to drive the 2019 at freeway speeds between the two chargers a few times with charging sessions in-between to see if the battery temperature profile is any different from the early version. My hope is that the '19 40kWh version mimics the 62kWh's performance.

Agreed, but that assumes that the Plus internal resistance has decreased over the 40 kWh, which is unknown. That resistance value
can be determined using LeafSpy. Last year a test was done that indicated that the 40 kWh Leaf had similar battery resistance to
to the 24 kWh Leaf.
#1 Leaf SL MY 9/13: 74K miles, 48 Ahrs, 5.2 miles/kWh (average), Hx=70, SOH=78, L2 - 100% > 1000, temp < 95F (35C), min discharge (DOD) > 20 Ahrs
#2 Leaf SL MY 12/18: 115 Ahrs, 5.5 miles/kWh (average), Hx=98, SOH=99, DOD > 25%, temp < 105F
