2021 M3 standard plus. Have a 240v nema 14-50 charger in garage.
So, what is the cheapest/most efficient way to charge the car? we have a 3.84kwh solar set up at home.
Best to charge at like 20a when the sun is shining until 4pm( when it’s peak electricity rates)? And or let it trickle charge in the middle of the night at like 5-10a until the sun comes out.
If we do have to charge at night, what amps are the best of time is not a factor, but we want to keep cost down?
Does it matter if we charge at night at 15a vs 20a for 8 hrs? Besides the range of course
What’s the best for the battery? Long slow charging?
Thx!
