ChargePoint Home Flex (Hardwired)

As we know, to draw the full 50A you need 70A breaker and 6AWG wire and hardwire the wall box. I am wondering if anyone has tried this for BMW iX?

There are some people who have tried it on Kia EV6 forums. Kia EV6 limits 11.5kW maximum.

The iX is limited to 11kW on AC maximum.

I don’t believe your charge point can do more than 48 so the 60 breaker is the highest you would need unless you want to future proof.
Chargepoint can do up to 50A, which is very minor difference. Total output difference 11.5kW vs 12kW.

I agree with you, 60 breaker should be sufficient for now.

I think the 60A breaker is the right answer to max out the charging rate for the iX. I had my home pre-wired for an electric car and have not yet looked in my breaker box to see if it is a 50 or a 60. I am expecting it to be a 50, and am now wrestling with whether I should upgrade the circuit or just get a charger which is variable and see how I go with 50. My iX should arrive in the fall, maybe sooner if it can ever clear QC.

I used to have a NEMA 14-50 outlet and 50A breaker- and the Chargepoint Home Flex charged at 9.6 kW. With a 60A and hard-wired, it's 11 kW- a 20% increase. I think that's nice- but- you would need sufficient gauge wire (#6 I think) before they can even change the breaker. I was lucky that the EVSE was in the garage on the other side of the wall our electrical panel was mounted in outside- so we only needed to run 2' of larger wire. The breaker was around $100 for the part.

My electric meter is right outer side of garage wall and inner side of same wall sub-panel with breakers. Wall Box is going to be about couple of ft from breakers. Let's see what electrician says.

I ordered ChargePoint Home Flex from their website, probable shipping in 3-4 weeks.

I got the ChargePoint Home Flex and it's on a 60amp circuit. It charges at 11KW no problem, and I haven't seen anything anywhere that says the iX can charge faster on AC only.
The ChargePoint app is also really good.

Got myself ChargePoint Home Flex as well, just got delivered today.

iX maximum charging speed is 11KW with AC current. Even though ChargePoint theoretically can deliver up to 12K, maximum you can use 11KW for iX.

Quick clarification… for those that purchased the Chargpoint - & are hardwiring… did you order the 6-50AMP or is it immaterial if it is to be hardwired

I am seeking 48amp juice and will have am60amp breaker for to-be delivered M60
thanks

It doesn't matter which plug you get because you will be hardwire the box. Electrician will remove the plug wire and connect directly.

I'm also installing 60Amp breaker for 48A, ChargePoint Home Flex. Make sure to get 6 AWG THHN wire for this.

I checked my car charger circuit, for whatever reason it had a 45A breaker. Put in the warranty claim on my house and they sent the electrician out the next day and swapped out the 45 for a 60. I confirmed with the electrician that the wire was/is a 6 Guage. I still am not sure whether I will put in any charger, at least not up front as my driving needs are not going to require daily charging, so the 11kw charge vs the 9.6 with the supplied is not much of an issue. The analytical side of me will be missing the data points, but I might be able to see the spikes in my hourly electric bill.
