I see you have both cars plugg in. Do you have 2 240 charge points?
No, we have an Schneider EVLink (you can see it in the background - we used the "forest" skin on it) and use the 120V LEAF EVSE if the other car is charging at the same time (if only one is charging it is on the EVLink). I've been considering the EVSEupgrade so they both can L2 charge at once, but in practice we haven't had that need. Each day both cars see lots of trips, from 6 miles round trip to 58, and we plug in both cars whenever they are at home (with the timers set to 80% on a 24x7 basis - when higher charging is needed we use the timer override buttons). To date we've never had a situation where we wished we'd had two L2 EVSEs.
