Change Amperage Charge Rate?

Hello, i just bought a 2020 Nissan Leaf with the 62 kw battery. My garage has 220/240 electric in it but only at 30 amps. The charger that comes with the vehicle is a 50 amp plug that I believe charges at 32 amps which would trip my breaker. I know there are 30 amp after market charges that charge at 80% or 24 amps. But, before buying one my question is: Does the Leaf itself have a setting that I can change that will only allow it to charge at let's say 24 amps and then I could use the charger that came with the car?

Common issue, and Nissan was stupid for providing a non-adjustable 28 amp charging cable when so many home 240 volt circuits are 30 amps and can handle no more than 24 amps continuously. No, the car doesn't have a setting for lower charging input amperage. You can check the gauge of your garage wiring or have an electrician do it. If it is heavier than the breaker rating you may be able to just upgrade the breaker. Otherwise you have to use an aftermarket charging cable or station.

I'll probably merge this with an existing topic later on.

And surprisingly a 24a EVSE isn't the most common to find. The cheapest EVSEs seem to be 16a and then 30a, 16a leaving lots on the table for a 30a circuit and 30a(27.5a max on a Leaf) being just too much for continuous use on a 30a breaker.
Some EVSEs like Juicebox allows you to select the amperage you want and Clipper Creek makes a couple of nice 24a models, the model has a 30 in it but that is for the breaker size, it outputs 24a max, perfect for a 30a breaker.
You might be able to find a cheaper(Chinese-made) 24a EVSE but again they aren't as common.
This name brand Siemens apparently has a internal dial to limit charging current and at it's current $327 isn't a bad price but it's 14' cable is a bit short and it needs to be hardwired in(or you could add a pigtail cord yourself).

I have something very similar to this and it works great, has 10/12/16/24 and 32a settings. You can even select the type of plug you want, in my case since I selected a 30a plug my EVSE maxed out at 30a, not sure if this brand is the same. If they didn't have your plug type you could always cut off the supplied plug and add your own, about $10 off Amazon(could be as much as $30 locally for 240v plugs).

This is one of the many CC EVSEs Amazon lists, again pick your plug type or some can be hardwired in.

Battery capacity is measured in kWh, not "kw".

Indeed.

Nissan should've provided something like Tesla's mobile connector (https://shop.tesla.com/product/gen-2-mobile-connector-bundle). They have adapters (https://shop.tesla.com/product/nema-adapter-bundle and https://shop.tesla.com/product/gen-2-nema-adapters) that you can buy as a bundle or individually. The EVSE adjusts its pilot signal to tell the car what it can draw at most depending on which adapter is attached.

Their gen 1 MC had different adapters (https://shop.tesla.com/product/gen-1-nema-adapters). Tesla's only been including a mobile connector where you get at least 1 adapter and can buy what you need since mid-2012. From them until maybe a year or two ago, they were always including NEMA 5-15 and 14-50. They dropped 14-50 as being included...

Thanks for the reply. I asked my dealer and he didn't know and was asking Nissan 2nd level support but who knows when they'll get back to me. Have you heard anything good or bad about an after market charger made by a company called SplitVolt?

No. I took a quick look at their website, and see no mention of an EVSE/charging cable.

If you are looking for a quality home unit that has a selection of amperage settings, check out this company:

Yes, I'm Canadian and shamelessly promoting a Canadian company

...is anybody familiar with Lectron? Is this one of those Chinese companies you were referring to?

OpenEvse has a range of options that you can either buy pre-assembled or DIY. I assembled one several years ago that has adjustable ampere settings via the menu and/or RAPI (programable interface). It appears that the current models must use wifi to adjust the amperes. Not sure if you can use RAPI to set that current manually on the standard models - would need to contact them.

I have this EVSE

I can sell to you.
PM if interested

If you are willing to settle for 16 Amps and your receptacle is a 14-30
