Most days I drive 30 miles, and I top off the battery in about one hour at home in the evening. I have been wondering what is better for battery longevity (please point me to the thread if there is one already):
- Charging at 40A for one hour (roughly)
- Charging at 10A for several hours (presumably 4h)
- Charging at 5A all night
Also, does anyone know if there is some kind of power consumption overhead throughout the charging process? For instance, the car is making noise while charging and I'm assuming that it's some kind of temperature regulation of the battery. If I charge at 5A all night, am I consuming significantly more power because of that current draw overhead than if I finish charging in 1h?
I'm planning on installing a power measuring clamp on my 14-50 feed to find out exactly...
