delayed charging to benefit from cheaper electricity

Post by SJM » Tue Nov 10, 2020 9:37 am

At the moment we cannot set up our ID3 to charge overnight on the cheaper electricity
If we plug it in it starts charging straight away
We can control, it partly by setting up charging with the app on our phone when we are actually in the car
Then stopping it but we then have to wake up when the cheap rate starts and start the charging from our phone
Apart from tearing our hair out we are losing sleep !
Our dealer has not been able to help us so far
Any ideas ?

Hi I have spoken to my dealer about this problem and according to vw they hope to fix it in January next year. In the short term I fitted a sonoff basic timer into the control cct of my rolec charger. Cost £10.00 You need wifi for it to work and must be 2.4 MHz band. So far over the last 4 weeks it has worked great I can give you a wiring diagram if you are interested

No timed charging yet, but it will come from VW.

For the time being I've switch my Octopus tariff from Go (very cheap from 00:30-04:30) to Agile (expensive from 16:00-19:00) and am charging during the day - usually in the mornings and on sunnier days as I have a small installation of solar panels.

Hello Robsto
We are certainly have wifi but signal not always great, which is another thing that concerns me about the id3
Not sure if we are confident enough to go down this route but it would be useful to see what is involved
so yes to the wiring diagram, thank you

Hi sjm
I am not able to copy a picture onto this forum this is the procdure The sonoff is connected to the control cct and not the main charging cct. Remove the live and neutral wires (brown and blue wires)connected to the controller at the top terminals marked L & N. Connect these wires to the input of the sonoff controller Connected the output from the sonoff back into the connectors use similar sized cable approx. 1.5mm. Set the sonoff up using app on phone As I said once set works great for setting times to charge. Hopefully the major software update promised by vw in January will sort out this basic problem for us

Thank you Robsto but we will continue to nag our dealer about the software update

I'm just using a granny lead at present and plug that into a Wi-Fi enabled socket ( that can be set with a routine to switch it on and off by Alexa or Google home. You just have to remember not to switch on and off more than once as it won't charge the second time. Given that we aren't doing massive mileage (only 2000 so far) I can't quite square the cost of a fast charger...

Hi - I'm new to the forum, having just put an order in for an ID.3 (1st Edition). I'm not new to EVs (got a Tesla too) and have a home EVSE (wall box) already. However, it's "dumb" and can't be set to charge at a specific time so this ability to do scheduled charging is actually quite important to me. I'm working on the assumption that it will come with the Dec/Jan big update, but I could really do with an interim solution.

I think this might be a potential route : https://smartcar.com/volkswagen/

I *seems* to offer an API to access some features of the car, including charging control. I'll do some more digging...

Another solution would be to use a contactor in the wall-box circuit controlled from a simple timer. However, that'll only work if the car will start charging when power is brought up on the wall box. Could anyone confirm whether this is how the ID3 operates?

I read somewhere of a guy who added a wifi-enabled relay inside his charger (invalidating the warranty), another who had a wifi-enabled breaker in his consumer unit - I can’t remember if this was specifically for the ID3 though.

Obviously you could simulate the effect of those to test the ID3 response by turning the breaker off, plugging the car in, then turning the breaker on.

I’ll wait for the software solution next month :-)
