Hi, Thanks a lot for the suggestions. Feedback is very useful
There are pros and cons to doing this. Our main concern when implementing Eco mode was that a user might plug their car in when it’s sunny in the afternoon but the solar PV would not produce enough to sufficiently change the EV before nightfall. The decision was made to keep the car trickle charging at 6A until it’s full. We also made the decision not to pause the charge if the solar PV drops below 6A since starting/stopping a charge very often would cause the EV’s contractors to wear.
In Eco mode’s current implementation there are two workarounds:
- If you know the sun will set in X hours after staring an Eco Mode charge, you can use the OpenEVSE’s charging limit timer to set the charge to stop after XX hrs
- Use the EV’s onboard limit to set a max SOC
I think a good solution for future development would be to pause the charge after maybe 1hr or zero solar PV gen, then have an option to resume charging during the night at a specific time to make topup the EV and make the most of low rate night time tariff.
Yes, it would be good to have an option for this. The reason we made reverting to ‘Normal’ the default was to avoid a user expectig a normal fast charge but only receiving 6A!
Yes, agree. I mentioned this in my comment above.
Thanks again for the feedback.
