Ohme Charging

[Koomi]

I think half of my comment was taken out of context by Andy there.

The integration with IO / OG and Ohme, for set and forget is valid and would be...

Car set to 80% if LR and wanting to save battery - otherwise 100% for SR or Travelling
Ohme App:
Dynamic Charing Off
Charge to Full
Price Cap 7p
(apologies if this is not the view IO customers get - the app updated after I left the tariff)

This will just take advantage of the 6h overnight window - set and forget... Economy 7 for car owners.
I don't think this will then ever need editing - and will be used for every plug in.

If you want to set a target with Dynamic Charging, and make use of the "extra" cheap slots if available, or more expensive rates to get the charge required... then do so.

If on Agile like I was explaining and got shot down - then setting either/or a Dynamic Schedule + Price cap gets the best of the system.
Need 60% by 1300 tomorrow, but don't charge if over 4p - it may say it can't get there, but makes use of all of the sub 4p slots

In the car, set the limit to 80% (in the app, click the battery, click the cog in the top corner, set charge limit)
On the Ohme, set to add 65% (if going from 20->80), IO and the charger will plan to add 65%, the car will stop when it hits 80%

Another thought - is the correct car picked in the Ohme? If you have selected the ER rather than the LR... +60% will be more.

My Ohme ePod dynamic charging appears to ignore the car charge limit.

On Thurs this week, battery at 14%, car charge limit set to 80%. I set Ohme to add 65% overnight. Next morning, battery at 87%. I understand Ohme deals in 30 min slots, so a 3KW difference might be understandable. This is more than that (61KwH useable battery), also the car should stop the charging at 80%. Oddly charging did stop at 80% when using a granny charger.

EDIT: The software is R16.

Normally it's the car that stops the charging as you specify a bit more than required in Ohme to make sure there is enough.

The charger knows nothing about the state of charge in the car.

The car should stop charging when it reaches its set limit, it is in charge. In the absence of access to the car's state of charge, I would have thought the ePod should stop the charge after it 'thinks' it has delivered 65% of the setting for the car that you specified in your account. You could test this by setting a low percentage to add, below that of the car's set limit.

I don't use dynamic charging with my ePod but my Trophy stops charging at the level I've set in the app. I'll have to do the test myself with/without dynamic charging when I get the time.

When I have not configured enough charge in the Ohme the charger stops at the end of the last scheduled slot even though the car hasn't reached it's limit value.

Where as I’m pretty sure in my case it just keeps going (or starts earlier), at least on IOG (I just plug it it every few days-and it just works and charges me the low rate 24x7?) - I don’t touch any settings

 

[mg4mc]

Why would it start earlier? The charger has no idea that you haven't configured enough charge for the car. I'm on IOG too.

My IOG charge regularly schedules an earlier start, normally only half an hour to be fair

 

[mg4mc]

Mine too, but not because I haven't configured enough charge to fill the battery.

From a number of posts above:

If you set the car to stop at 80% - it should stop at 80% even if the charger is set to more... plugging in at 75% and telling the charger to add 100%, should stop after 5% - if it doesn't then there is an incorrect setting, or problem with the car

If the charger is set to supply less than the car capacity/cut-off it will stop after it thinks it has delivered that much (% will be slightly out due to guessing, rather than being able to read the SoC)

Setting the Ohme on IOG to add 80+% on each charge, will program IOG to try to add that much at cheap rates whenever it can fit it in.
If only needing 30% that could be fulfilled during the normal cheap hours, it's kind of cheating the cheap rate into existence outside of the window... but that is how it works (and then means cheap rate for the whole house at those times)
A tangent to this - if you have a car that IOG can talk to directly... setting it to charge, and using a granny charger, will put your whole house on 7p whenever possible
