At present we have a dumb Rolec 7kWh unit that is used to charge Leaf.
A few months ago, I picked up Outlander and I am primarily using manufacturer supplied 2.4kW EVSE using mains socket.
I was wondering if it is possible to create an EVSE that supports multiple heads being plugged in simultaneously and being able to charge independently too
Hello @Hermit_Dave, @glyn.hudson may be able to help with this one, I think the answer will be that you need an EVSE controller and contactor per socket and then would need to design the ratings of everything else appropriately
It would be possible to create a double-headed unit using two OpenEVSE controllers and two contactors. However, I can’t see any advantage of this over fitting two units.
In a domestic installation you would probably need load sharing between the two units to avoid a 14kW additional load which would most probably not be allowed by a DNO. EVSE’s installations are now required to be DNO notifiable.
I suppose I need two load sharing EVSE controllers. Rolec doesn’t have load sharing capability unless only one needs to be capable.
I was looking at Viridian EVSE controllers - they seem to support load sharing so in theory I could replace existing EVSE controller with Viridian and DIY another unit
It’s all relative. My first Time of Use tariff was EDF 20:20 that required specialised meter. I used that for a decade before upgrading to smart meter while on equivalent EDF Go Electric last year.
A few years ago I came across TIDE tariff which was the first time I heard Time of Use though no where near as dynamic as Agile.
It is, but you said the only TOU tariff. I was just pointing out TOU has been around for a while albeit in a very static way. Agile is the first to price in relatively short time slots and that price is set on a daily basis.
