80 amp wall charger pro

[Junior]

I want to have a hardwired wall charger in the garage and keep the one that came with the mach e in the car. I have a chance to get the 80 amp at a good price just wondering if it'll work on the mach e. It can be knocked down to 60 amps if 80 is too much. Will it charge the mach e or should I just pass on it?

It’ll work, but the MME won’t draw more than 48 amps.

The charger will work. This is the selector switch for choosing the maximum amperage.

Just know that whatever you set the charger to, the most your car will draw is 48A.

Wire it up to 100 amps if possible - some day you’ll have that 19.6kw capable vehicle!!

Almost a decade ago…geeze; I installed a 6.6kw EVSE when my Leaf at the time only was capable of 3.3 kw.

What we are talking about IS level 2.

And this is why we keep learning!

L2 (240 volts) charging on the Mach E is limited by the car to a max of 48 amps. An EVSE capable of delivering more will still only deliver a maximum of 48 amps to the Mach E. But in case the OP ever gets a car that can charge at a higher rate, having a higher amperage circuit could be useful. Of course their electric service and panel need to have sufficient excess power to make that feasible…

Thanks for explaining.

Yes that's exactly what I was thinking about down the road. At least my option is there. Sub panel I have in the garage is 100amp

Thank you all for the quick replys and information. ?

Sightly of topic here but,
What happens if I connect to a 240v outlet 50 amp, but the EVSE is only rated to 32 amp. Will EVSE just draw 32 amps regardless or will it get over heat

It will just draw up to the max it's rated for. No different than plugging in a lamp to a 120v/15 amp household outlet and it only drawing what is needed for the bulb. 240v doesn't work any different other than capacity differences.

You could plug a 32 amp EVSE into an outlet wired for 100 amps and it would still just draw what is needed. It's not a firehose, where water pressure is a direct force coming out the other end, it's more like a river and your outlet is just taking a drink from the river bank. A wider river doesn't mean you are forced to drink more.

Great analogy, I'm slowly "picking up what what everyone is laying down" here. So much to learn and understand on the EV's .

Your analogy totally makes sense for this usecase. ?Thanks for replying
