Hi, what percentage are you setting the Ohme EVSE to add?

 

I'm currently sitting at 45 I've set a target for 40
I usually take it to 85 but as said it fully charges

 

Always intrigued by these chargepoints that claim to charge to a percentage. The protocol used for AC charging does not read the car battery unlike rapid DC chargers so the chargepoint can never tell the charge level.
The only way this can work is the chargepoint communicating to its internet server and then the server talking to the car's internet server and the car's server talking to the car and communicating any findings back up the chain to the chargepoint. The chances of this working in real time are slim and are dependent on nothing changing or being updated by any of the machines on the path.
I'd be thankful it works at all, though that may just be the fall back position as one of the links on the way is down or offline or just can not get a connection

 

Can you post a screen shot of you settings

 

Such issues are caused by communication problems- as indicated by @Spiny. In the past, I resorted to using the car's timer instead. It needs a bit of mental arithmetic to work out how long the charge point would take to deliver the necessary kWh from the start plug-in state. And can never be perfectly accurate unless your math is meticulous. But the charge will stop when the required kWhs have been sent to the car. An example for a Leaf 30.

Start SOC 30% = 9 kWh in a Leaf 30.
85% of a Leaf 30 = 25.5 kWh.
Need to add 25.5 - 9 = 16.5 kWh
Charger adds 6.6 kWh per hour.
16.5/6.6 = 2.5 hours.
Set car timer to 2 hours 30 minutes.
Result - charge stops then and is at circa 85% SOC.

 

If possible, I would recommend disconnecting your Ohme from your car's API (but still tell it what model you have). Then it will always assume the car is starting at 0% on plug-in. You just tell it what % to add, rather than what % to stop at. Works very well with no Comms between the charger and car. I have never given Ohme my car's API data and used this method for around a year until VW fixed the car's own scheduling software (which I now use instead of Ohme's).

Thanks I'll try that

 

As above, I just set my Ohme to add %x of charge to take it up to 80%, based on the state of charge I saw when I parked my e208 or as shown by the MyPeugeot app. In my case, I have to do this because the Peugeot API isn’t supported by the Ohme. In practice, it’s only marginally more involved than if I could set a maximum charge %, as I have to alter the Ohme Schedule most times. But it works fine every time, albeit the Ohme is -/+ a percent out sometimes i.e. finishes at 79% or 81%.

 

Morning done 2hat you suggested last night still took me to 100 ,can't get through to ohme emailed 9n the 30th September still no response

 

I take it you have set up the Ohme with the correct car model so it knows the correct battery size?

 

That was 3 months ago

 

Hi I have an ohme home charger and drive a 2021 nissan leaf, when I'm setting a charge target to take the car to 85 %it keeps charging to 100% ive emailed ohme they suggested turning the charger off for 2 mins and try again ,I've done this but still the same ive not had a reply from ohme as I emailed them to say it's still the same any help would be great ,ps they told me their app is having issues with nissan leaf as I used to set a percentage and they requested I set a target
Once again any help greatly appreciated

This problem with Ohme and Nissan is still on-going. I just bought an ePod through Octopus and the ability to set a required morning charge level doesn't work. Once you pair your car (mine's a 2021 Leaf+) the range figure misreports as 87 miles and all the charging calculations are wrong (very insufficient charge added). I tried unpairing the car and chose to add a certain percentage to get me to 80%, I had to stop it as it would have got to about 90%. Very unimpressed that Octopus are still listing and installing a product that just simply doesn't work properly. Do any of the other mainstream chargers integrate properly with the Nissan Connect info?

 

Something to be aware of when using Ohme without API integration - with any car - is that it will just equate 100% to whatever kwh value is specified in the car profile you select in the Ohme app. This can easily be wrong for two reasons. Firstly it doesn't account for degradation. Secondly there are multiple profiles that have been created for the same car with different data - for example there are different profiles for the ID4 with 77kwh (the net figure) and 82kwh (the gross figure, which is incorrect for this purpose) capacities. If the actual usable capacity of your car's battery is a bit less than what is specified in the Ohme car profile you select, then it will always add a bit more than you need. If your car has a charge limit you can set, this doesn't matter because it will stop it anyway when the car's limit is reached. If it doesn't, you'll need to mentally multiply what you want by a factor (e.g. 0.9 if it is adding 10% too much) so that you get the right result. It'll be the same factor each time unless your car's battery degrades or you change the selected Ohme profile.
All the above applies whatever tariff you are on. However I think Octopus still advertise Intelligent as a beta tariff because they know it still suffers bugs in most incarnations, not just with Ohme.
