Home EV Charge Station

[Yellowtail]

I am in the process of moving and plan to install an EV charge station at the new place. We'll have three-phase, and as I understand it, 36A is plenty. Is that correct? 

 

Also, any recommendations for the charge station itself would be helpful. There seems to be quite a variety.

 

Thanks!

You want a 22Kw 3 phase charger, that will charge single phase at 7Kw too.

 

Don't be tempted to buy an 11Kw 3 phase charger as it will only charge at 3.6Kw on single phase.

 

Is it going to be in a place where a neighbour might come and charge his car whilst you're away?  If so, get one with an RFID card to begin charging.

 

If you're getting an electrician to fit it and there's any chance you might want to move house and take it with you, then I would also install a red industrial 32 amp plug and socket where you're putting the charger and put the plug on the charger.

 

There are loads of 22Kw wall boxes on Lazada.

Our is routed from a mains-breaker in the house, it can be isolated (to off) if we wished to do so.

 

But really, is that something that happens ?.... Neighbours parking in your drive and using your 'charging station' ???

No, that's not the case.

I will likely fit it myself, but I'll have an electrician run the drop.

Yeah, it's a bit intimidating given I recognize none of the brands.

I've seen it on TikTok, but I suspect it was a fake and clickbait.  More likely to happen if you're in a condo I would think.

There's not much inside the boxes, some sensing circuits and a contactor.  I wouldn't be tempted to spend too much on one, just keep it cheap and simple.

Ours is a 22kW Wall Box...     (Type 2 plug)

 

Which actually works on a 15/45 3x Phase...    (i.e. each phase provides 15amps) 

 

I believe this charges at 10.4kW 

 

Thus: Mathematically it would take approximately 8.4 hours to fully charge our 88 kWh battery (from zero to 100% - with 100% charging efficiency).

 

Real word charging efficiency is approx 90-95% - so we're looking at 9.5 hrs for a full charge.

 

Real Real world charging: we rarely get below 50% running around BKK... so the charge is only ever a few hours to top up... i.e. Plugged in every 3rd night or so....

 

 

Location of the wall box to where the car is parked is obviously a key point.

My station came with the car. For free.
