Hi,

Following some early days experiments I was able to get the Ohme charger and the ID3 to work together to charge off peak (12.30 - 4.30). Both devices were set to charge between these times.

The ID3 was set to depart at 8am and it commenced the air con/ heat cycle shortly before 8am. However as this was outside the off peak period the energy came from the battery.

I spoke to Ohme today and have some info to pass on :

1) Ohme have a setting which allows the ID3 to be kept awake via a trickle charge. Select the ID3 trickle via the ohme app. Setting > change Car.
2) Ohme are working on a feature which will allow the charger to provide energy in the lead up to the departure time. This is highly requested (so please send them a request).

Also Ohme don't have the Pro S "Tour" version selectable in the app (if you have a Tour send them a request to add this).

Thanks

Is the setting actually named that - an ID3 trickle?

I've read a few places that state 6A is the lowest an EV can charge. Does this mean the Ohme will let 6A through until the start of the timed period? About 1.5kW?

Yes ID.3 trickle (2020). Yes suspect around 6A.

I have been able to get it to charge without this between 0030 and 0430 by setting the preferred times in the car and setting ohme to use octopus go off peak. I think both are waking up together.

The e-Golf could charge at 5A which was perfect for charging from solar on overcast days.

I've had an Ohme for a few months and not once have I needed to set anything in the car. I plug it in and then set the Ohme to only charge at the 5p rate. I can leave it for days without touching either the car or the Ohme and it will just continue to charge at the 5p rate until I unplug one from the other. No trickle charging happens in the background (verified by the energy meter) or anything like that. The Ohme just wakes the car up when it's time to charge.

I can set other timers on the Ohme but don't generally need to but it has always worked even with my car being on the 0564 software.

Ohme have added the ID.3 Pro S to the car database and it is now available in the app.

Just when this piqued my interest in the Ohme, we start to see reports that 2.1 has fixed the issue in the Zappi.

Decisions, decisions.

This is how to send Ohme that request - they have a webpage where they are asking for input. Please review and vote on the suggestions there, it's getting good engagement.

I didn't know about the feature request email. They implemented the Pro S yesterday.

I find this talk about sending a trickle charge odd. That sounds to me like the Ohme is not managing the initial handshake with the ID.3 well enough.

I have an Andersen and it does timed charging just fine - without the need for any trickle charge (it literally is delivering 0 between plugging in and the scheduled charge times starting). When I plug in to the car (having already set the schedule on the charger), I know that the handshake has taken place at that point as the car wakes and the ID light lights up as a ‘dashed’ green light so it’s awaiting charge - then lock the car and that’s it. X hours later the charger starts delivering the charge and the car accepts it.

It is working fine. I've had an Ohme for a while and it does not need to trickle charge to keep the car "awake". The display on the unit even says 0 Amps and the power transfer figure remains the same throughout the standby phase.

It works just like your Anderson.

 

[ransomz0]

Yes it works fine without a trickle charge.

Maybe I’m missing something then....what’s the point of this thread?!

 

[YoWombat]

I think the general problem is that the ID doesn't stay awake to accept charge when the charger thinks it should be charging.

That means for use cases like Octopus Agile, or consuming excess solar (so the Zappi has problems in Eco+ mode).

However, if the car has a configured charging time, then it does wake up and consume energy.which works OK for use cases like the Ohme and Octopus Go, so long as both are set to the same time.

However, it looks like this issue is fixed in v2.1 software (of the ID)

 

[Mr_ess_jay]

You don't need to set timers in the car for Ohme. Plug it in and the Ohme system does as you program it to do. Always has.

Zappi users are the only ones struggling as far as I am aware.

New to using the Ohme and the ID3, naively thought the trickle charge was a work around. Turns out it isn't required. Forget it happened.

How much did everyone pay for a fully installed Ohme? I'm being quoted £579 and that's to tie onto an external meter box on the outside garage wall with a consumer unit put in the meter box. Not sure whether that's good, bad or indifferent. Awaiting a quote from Ohme's own appointed installers for the North East (they seem to be based in Scotland).

 

[Mr_ess_jay]

£559 or £549 seems to ring a bell.

Hi,

I bought the Ohme charger (commando socket version) £150 for Octopus customers in the Christmas sale. Garage consumer unit for £31.99 from screwfix and Interlocked outdoor commando socket for about £40 from memory. I ran the cable myself between the consumer unit to outside wall and a local electrician commissioned it either end which was about 1.5 hours work. Also installed a small meter at the consumer unit end which is on the circuit for the commando socket so as I can measure energy delivered to the vehicle. So probably about £400 all in.

This is exactly what I've done in the past. However...be aware that it does not now comply with the latest regulations for electric vehicle charging. If your supply has PME earthing system - which is by far the most common arrangement in the U.K. - then you also need a device that detects a neutral fault. Examples are Matt.E or Garo. Will add cost...probably £100-150 on top.
