Now that we have two Leafs that only draw 3.7 kW each, I am wondering if the L2 Blink unit at home can be mod to charge both at the same time (when is going to be mine, of course). Right now I charge one Leaf overnight and the second one I plug in at 5:00 am when I get up for work. There is not TOU here, but in the future it might be. In addition, I would like to charge during off pick hours.
What needs to be done?
1 - AC splitting
2 - Pilot signal splitting
3 - Diode check splitting
Issues:
4 - what happens when one car is done?
5 - when only one car is plugged in the other connector will be HOT (on the wet ground ...)
Solutions:
Add one extra relay and multiplex the control signals?
I will look into it next weekend, just out of curiosity for now.
I know, I will likely build a second EVSE, but I had to bring this up as a posibility because I was thinking a while back about the Blink "dual" DC chargers. They can draw 50kW max, but above 60% SOC they charge at about 30kW. It will be great if the other side could charge at 20Kw instead of just waiting for 20 minutes or more. (I had to wait for somebody going to high SOC :x )
