evtifosi said:I have had the 50A OpenEVSE for just about a year, and just started to use the on board timers to great effect.
For a few months I used the Leaf timers, but those became harder to work with when I needed to charge during the day for some reason. I eventually just turned the timers in the car off.
I started playing around with the current options to reduce the amount of charge I was getting, and then finally decided to just use the OpenEVSE timers. I have them set to start at 4:05am - and shut off at 6:55am. This will charge my 2015 SV from close to 20% to 100%, and if I am around 10% or lower it will typically charge it back to around 85%. It seems like a good setting for our limited use. I am on PG&E E-6 TOU rate plan and have Solar Panels...so this guarantees that we are charging off peak.
I got tired of remembering to go out to the garage after 9PM or plug it in when I woke up in the morning - so I love the timer function - just wish I had used it sooner!!!

gridstop said:I know the Open EVSE supports changing charging current via the serial interface (and by the UI), but can this be done in the middle of charging? Or does it have to stop and re-start?
And will the leaf respond on the fly and lower/raise current? I've been thinking about whether Open EVSE could be used to make a dual charger for a single 40A line and negotiate current between the two of them. Or possibly sharing a single 40A line with a garage heater (so when the heater is on, lower current to 14A or something).
