Re: The 40KWH Battery Topic

Godzzi wrote: Thu Dec 16, 2021 12:24 am Latelly I've been running tests with my 2018 Leaf 40. These tests were done to determine real SOH and compare with what LEafspy is reporting. Here it goes:

- Details: 20000km - SOH 91.4%
- Charged to 100% on the dash (leafspy reported 97% and 35.1kwh inside the battery)
- Drove to 0% on the dash for 197km. (leafspy reported 33.1kwh consumed so far + 3.3kwh remaining). Average consumtion on the dash 15.3kwh/100km
- Drove another 10km until turtle mode kicked in (leafspy reported 35.3kwh consumed so far + 1.2kwh remaining.
Good stuff!
I need to do something similar (I put a 40 kWh pack in my Gen1 Leaf), if for no other reason to "smoke out" a weak cell I'm seeing evidence of. I'm also curious how my (old) BMS will affect the reserve in the (new) battery pack.

Re: The 40KWH Battery Topic

IIRC, mine had about 92% when I sold her to the dealership last Spring. (I still can't believe that I was able to sell them my lease return!)

Re: The 40KWH Battery Topic

I'm jealous of the 4mV cell balance. I have several weaker cells and have a 22mV difference. My 2018 only dropped .5% in the last 7 months.

Also... take your readings with SOC fully charged, will likely be closer to 3-4mV spread.
2014 SV - Brilliant Silver - returned 1/2017 at end of lease.
