The NEC states that a continuous constant load cannot exceed 80% of a circuit's rated capacity.

A 50A circuit should never be used for vehicle charging above 40A. (80% of 50 is 40.)

Likewise, the EVSE should be set to no more than 24A when using a 30A electric dryer outlet. (80% of 30 is 24.)

 

Im aware. I have the internal rotary switch set to 24A.

Im asking about when I actually have a dedicated circuit installed, will this unit allow me to run at 50A if I hardwired it with a 70A breaker. In other words, is the 40A 14-50 version internally the same as as the hardwired 50a unit.

It honestly doesnt matter if it does to me. Up until this point Ive driven my bolt 3000 miles in 2 months just using the 120V charger that came with the car. Even 240V/24A is plenty. I was just curious.

 

If you want to set a limit on your 2018 Bolt, just turn Mountain Mode on. That's as good as it gets.

 

It's called Hilltop Reserve mode on the Energy settings screen of a 2017-2018. Enable it and it limits the charging to around 88%. See page 140 of your Owners Manual.

 

Here is some of where my confusion is coming from:

But then they go and say this:

And yes I understand that my Bolt can only accept 30A/7.2kw but if I have the opportunity to install this as a 50A unit I would rather do that now than regret it later down the road when I have it wired as a 40A unit.

 

Honestly, I think I am just going to turn the internal switch to 50A and see what it does without the car plugged in. The Autel app will tell me what the maximum charge current is set to. Unless the charger has some kind of software limit, or secondary hardware limit specific to this model, it wont know that its hardwired or not and should show 50A within the App.

 

Cell balancing happens with every charge. 2017-2021 Bolts max AC charge at 32 A, not 30.
