EV charger load

[Toros]

Hi
Do we have to allow 9600 VA load for E.V charger in the load calc????

Thank you

A typical level 2 home chargers fed with a 40 amp breaker and will use a max. of 32 amps continuous load. If you want to limit the home to this charger think the load calculation should be 7,680 watts, not the 9600 watt amount, and added into the total demand at 100% with no demand factor reduction, similar to a heat pump or AC.
But there are larger chargers. I have installed an 80 amp Tesla charger which is fed with a 90 or a 100 amp breaker. So is that a 19,200 watt load? These are new questions for new equipment usually run at night, often at specific hours such as 11 pm to 6 am to obtain the cheapest rate from your utility. ...I do not know if anybody has decided on how to add EV to load calculations. Any help out there?
Our local code says provide for EV charging in the garage. To comply with this we run one inch diameter flex to a junction box in the wall and leave it empty. All new services are 200 amp minimum. What if you have two Teslas?

That's easy, give me one ... <g>

I think their chargers inter-communicate to limit total load with 2 (or more?) used.

652 says it is to be treated as a continuous load.
