Level 2 Charging Best Practices?

[TaxmanHog]

@TaxmanHog On a different thread, you indicated that you charge infrequently. I don't recall exactly, maybe once or twice per week. Regardless, what SOC levels do you typically charge from and to?

My goal is to charge weekly, but when new OTA's or FP App updates roll out I will break that rule, also if I have a road trip (monthly) then I have to do more, this week I charged on Wednesday & Sunday.

How low do you let your SOC go?
What level do you charge it to?

I charge as needed, meaning it could be a few times a week or once every few weeks. My target is to keep the truck between 50 and 80% SOC. I will plug her win when super cold and will charge to 100% if going on a trip.

As low as it may go, but no lower than 20%
90% is regular stopping point unless preparing for a road trip, then 95%

Older thread I guess I already responded to, but a few more thoughts.

Internal resistance is higher with a low battery temp, which will cause more internal (passive) heating. I believe that this suggests charging in larger amounts or charging immediately after long drives. It may also suggest charging at higher rates.

To the same end active battery heating can come into play, which would also imply one should charge in large amounts so that you minimize the number of times you expend energy heating the battery.
