EV Charger Recommendations

[carlyai]

Hopefully purchasing an EV with a 82.5KWh battery capacity.

We have 3 phase supply, but at the moment only single phase to the garage which will be upgraded to 3 phase when we install the solar.

So initially we would have a single phase charger then hopefully with the same charger re-configure to 3 phase.

We have a 60 A mains 3 phase breaker and 45A PEA supply.

Cable is 1x25mm.

If we configured the charger to 7KW charge, that would deliver 32A charge and take 12 hours (from 20% to 80 battery charge).

The charger would eventually be charging from the 3 inverters or battery if I go full solar.

Any thoughts on a charger? and hope my maths is OK.

82.5kWh sounds like it could be a BYD Seal, that's the size of my battery and it came with a free wall charger and installation. 

 

I have off-grid solar which powers the house and 2 EVs.

 

I've never had 3 phase so can't be any help on that one. 

 

If I run the battery down to 20% I tend to charge it back over a few days.

I have asked on that forum as well.

Decided on a 7kW/23A single phase charger.

Just waiting for any responses on brand recommendations..

There are many brands on Shoppe and Lazada.

Great forum and knowlegable people on Electric Vehicles in Thailand forum.

That should be 32A.

 

My PEA installation is 3 phase 15/45.

What are your thoughts of squeezing  32 to 40A out of my system if the pool pump and EV charger are in at the same time.

 

I think OK.

 

I will buy the BYD 7 kV charger from Lazada or Shopee.

I have the same question as carlyai. But you guys in the EV forum are always so focused on cars rather than electrical questions ...

 

May I ask what is the reason you kept the car charger on single phase?

 

I'm thinking of a car port the style Crossy has built. So seeing these 3 phase inverters now being not much more expensive than single phase, I thought this has advantages if you parallel 2-3 of them. The currents on the AC side  would be in a region I'm comfortable with, where with 10+ kW on single phase seems already a bit high for me.

Probably because most people have 1 phase electric at the house.  Auto maker supplied Wall box charging cables (7+kWh) work fine with 1 phase, as does the emergency/granny charging cables (2+kWh).

 

If charging overnight, more than enough for most folks daily driving needs.   Easily adding 100-150 kms daily overnight.
