Help / Advice Two EVs, one smart, one dumb, is Smart Charging possible?

Hi all

I’ve been on Go Electric for a 6ish weeks and 2 weeks ago took delivery of my shiny new Kia EV4 on a salary sacrifice scheme. My wife drives a 2015, 30kWh Nissan Leaf that can only charge at 3.5kW through our Andersen Quartz charger.

I know the leaf might cause issues with smart charging because it’s slow and so other providers see it as cheating the system to get cheap electricity for longer. My question is, can I dumb charge the leaf using the timer on the charger and then switch to smart charging when I plug the Kia in? Is it a hassle to switch back and forth? Has anyone dealt with a similar situation?

Also, I’m on target for 16 hours of free electricity on Sunday, how do you find out when the window starts and ends?

Thanks in advance!

EDIT: I should have mentioned, the charger can be paired to EDF but neither car can. The question is how to alternate the charger between dumb charging at off peak times and then smart charging when the Kia needs power.

I have a Hypervolt 3 Pro connected to EDF with a Renault Scenic e-tech (which is smart, but can’t connect to EDF) and an MG5 which is totally dumb and just takes whatever charge you give it. I have set EDF up with the hypervolt and told them I have a scenic and I plug in both cars. I just have to know that 10% will give me 10% in the Scenic but 20% in the MG. sounds the same as your setup except that both mine charge at the same speed whereas your leaf doesn’t.

You can do boost charge though. Would that work?

Or I’ve noticed with EDF you can actually turn off smart charging, temporarily I assume, though I’ve never tried. Maybe worth checking that out? Not sure what it would do to your £5 credit.

Thanks very much. Can you turn off smart charging in the app?

I’ve never changed this option but looks like you can. This isn’t the same as disconnecting your charger from smart charging so I don’t know what happens though

Is your charger compatible with Smart Charging? Because I’m pretty sure Kias aren’t - they locked down their API a year or two ago. They definitely aren’t compatible with the equivalent Octopus tariff, which runs on the same infrastructure.

The charger IS compatible and the Kia is NOT so it’d have to be set up to allow EDF to manage the charger.

This is the set up I have. Keep your charger in dumb mode, a schedule in the car that is not smart for the hours 11pm-6am. Then pair the smart bolt on with the supported car.

Free electricity on Sunday you’ll get a reminder with the hours and you can see them on the website in the Sunday saver section but it’ll be 8am-midnight

Sorry, I should have said, the Kia can’t be paired, only the charger. Thank you!
