Re: Amps for a new charger ?

Sat Dec 05, 2015 4:48 am

OP is looking for an EVSE, not a charger. OP should look at viewtopic.php?f=6&t=14728&p=332668#p332668.

Today, I became aware of this decent article on the subject at https://transportevolved.com/2015/11/28 ... ers-guide/ via a Plug In America newsletter email.

'13 Leaf SV w/premium package (owned)
'13 Leaf SV w/QC + LED & premium packages (lease over, car returned)
'06 Prius

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Good link to another topic. But I wonder - who said the OP was looking for a "charger" as opposed to an EVSE? Or are you splitting hairs here and emphasizing correct nomenclature?

As for the link to the article, I'm not sure this is helpful. In the article they say "How much does your car accept? Most cars fall into two charging levels: 16A or 30A. Some take more, 32A, 40A and even 80A. The more the car can accept, the faster you can charge it. Once you know how much electric current your car can accept, you can decide on the size of the wall unit."

I don't think this is true, is it? It is my understanding that the Leaf comes from the factory with either a 3.6kW or a 6.6kW charger built in. If you get the quick charger option, then it is even higher than that. So the car doesn't accept a given current, it allows a certain power level. So, if you have a 120V supply, a 3.6kW charger could accept 3.6kW/120V = 30A if it were available on that 120A circuit, or 6.6kW/120V = 55A from the larger charger. Of course, I don't think 120V circuits are available that deliver 30A or 50A. That's a big current. So you go to a 240V circuit where you could accept either 15A or 27.5A, depending in the power of the charger.

So, can the car accept a certain maximum current, or is it regulated by the maximum power of the charger, in which case the maximum current accepted depends on the circuit?

Of course, for the OP, this may all be irrelevant...

It's in the thread title.

Yeah, okay. But I think we can all agree that the OP is really looking for an EVSE, despite the (common) misuse of the term "charger" in the title. I'm not aware of anyone who was actually looking for a new "charger."

Unlikely to notice a difference between 24A EVSE and 30A models in everyday useage. But lots more to choose from at 30A, if that's any consideration.
I noticed you're still working with polymers.

Hey thanks for all the info did not mean to vanish after asking the question and asking it wrong as well. But new little grandbaby came into the world so been at the hospital quite a bit as she was a bit early but all is well. So dealer told me my new leaf will be here in a couple of weeks so I have time to get it ready. So again thanks for the info and I shall figure out what i need this weekend

Clipper Creek has the fastest EVSE to run on 30 amp supply with the HCS-30

http://www.clippercreek.com/store/product/hcs-30-24-amp-ev-charging-station-25-ft-cable/
1 bar lost at 21,451 miles, 16 months.
2 bar lost at 35,339 miles, 25 months.
LEAF traded at 45,400 miles for a RAV4-EV
