I have a 2020 model 3 Plus
I have a 2020 model 3 Plus and only drive around 10ks per day .
I have yet to install the fast charger at home and really don’t need too as the house is solar powered predominantly where the car charges quick enough to not have to think about it .
My only concern is :
A leaving the car on the charger is pointless if your trying to run the battery below 50%
So I just charge it from around 50% back up to 90% once a week on a sunny day for free
In terms of trickle vs blast charge I have only ever charged on the 240volt plug in charger and it works fine so the logic is charge at low speeds from 10 to 90 percent full and your giving your battery the best chance of long term survival
If this is correct then please confirm as my assessment of the over all process is to be low speed charging without pushing the extremes
