Hi all,

I've seen some chat about this but struggling to arrive at a conclusive answer.

I normally charge the car upto 80% every couple of days. I have a big journey this weekend so would like to vehicle to be at 100% just in time for departure at 8am. I have an Ohme smart charger. What's the best way to achieve this ?

Thanks

Yes, but as far as I know the ohme is only guestimating how much and when to supply charge. So I am trying to work put if it is better to use the ohme as a dumb charger and allow the vehicle to schedule 100% for 8am departure.
That’s the way I use my Ohme, I’m on a 24/7 flat rate tariff, so just use the in car timers to set the departure time.

If you're on a cheap overnight tariff, don't you want to restrict the charging to that window? My cheap rate runs from midnight to 5am, so my smart charger is set to only charge during those times unless I manually override. So if I'm taking a long trip, all I do is change the maximum SOC in the ID.3 from 80% to 100% before going to bed the previous night. Means it will be sat at 100% for a few hours from 5am to whenever I depart, but, y'know, I'm a brave soul so willing to take the risk of it blowing up as per the manual :D

Though, I accept if you're starting off at a low SOC it may not totally get to 100% over 5 hours of charging. If I'm ever in that scenario, I just override the charge timer before I go to bed to start it charging a bit earlier than midnight.

I've got my first proper journey that I feel like needs the comfort zone of 100% SoC tomorrow and that was gonna be my plan.

Yup as others i have Ohme but single rate tariff. i currently use the we connect app to control charging. however when i get a smart meter and move to different tariff i will set the car to 100% but the Ohme to whatever i need (usually 80%) and have that scehdule the charge rate by the kwh cost.

I think this is the optimal way with the Ohme charger (but would be happy to be proven wrong)

I'm not sure Ohme works that way. From what I can tell it allows a certain percentage to be added not charge to a certain level. Might have this wrong so happy to be corrected

Becuase of you are using ohme to limit the charge to a certain cost, it won't allow you to get the car to accept a charge.

When VW add the ID3 to the app api to allow Ohme to talk directly to the car, then this will change.

I thought the advice from VW was (ideally) not to leave it at 100% charge for longer than 12 hours? So in most cases its possible to charge on a cheap overnight tariff when needed for a longer journey and still stick with what's advised?

my car is charging atm and the Ohme app lets me add +80% or 209 miles. But although it should be interpreted as +80% (ie adding 80%) i think it just charges to 80% - but will confirm when it finishes :)

Without the proper timers (still on 564) for long journeys I charge to 90% overnight on the cheap rate and then charge to 100% the next morning when I get up so it's at 100% for the minimum time.
