EV - after few pointers please

[sythai]

Hi Guys

Not been involved with any EV much as of yet. But time has come now with new LABC regs that we have to fit on all new builds.

Did the Niceic (think was 1/2 day) EV course 2-3 years ago, then signed myself up as a pod-point installer.

That was about it ! All the OLEV paperwork put me off, looked like a right headache !
Also bit concerned that wouldn't be able to figure out set up for any app to get it working after install - I'm not so tecchy, but my younger employees probably figure it out.

Did get quite a lot of customer enquires and if we ever went quiet was going to do a few - never happened though.

So all we've done to date is put in the 1st fixes ready for any EV point at a later date.

Few questions if you can help on please :

- Do I have to inform ENA / WPD of every EV point we install, even if has load limiter on it ?

- How do I inform ENA / WPD is this all on line ?

- Can I install any EV charger or do I have to be 'approved by the manufacturer' cant remember the benefit of becoming 'pod-point installer maybe longer warranty ?

- Any EV chargers you recommend the are easy on final set up assuming they all have an app ? Or maybe there's some that dont need the an app.

- Been specified on a new build coming : Zappi 22kW, anyone fitted this unit ?

Thanks Sy

What KVA have the DNO supplied as that looks like a 70KVA max head. So if you want 80KW for charging you will struggle,

Yes correct - 70KVA (3off 100A fuses). As with EVSE's, the DC charger can be configured to limit power delivery so the main fuses don't blow.

I got a quote for 3 phase upgrade some years back, the cost for which I wouldn't describe as nominal.

It involved no trenching, but did include several poles, a lot of expensive cable and a new transformer. I imagine the cost would now be a quite significant five figure sum as nothing has changed with local distribution.

Sounds like you haven't been involved in organising supplies to buildings before, there will likely be a very large difference In single and three phase.

Well lets say you are building a housing estate. Developer will arrange for DNO to lay 3-phase in the pavement on each side of the road. That is the expensive part.

Each house then needs a feed and here you have a choice of single or 1 or 3 phase cable / cut our, and that's the bit with nominal material cost difference and almost zero labour difference.
