Exactly right. The Nissan charger is a weird design because it draws less than 10A but has a 15A plug. That means you can find a charger that draws almost 50% more power through the same plug aftermarket.

Am I right in thinking that the one supplied direct from Clipper Creek would plug directly into the same 15 amp outlet required by the EVSE supplied with the leaf, and will decrease charge times by about 1/4? We are planning to try to do most of our charging from solar panels as we have a 6kw system, so I think having a quicker charger will probably be needed to achieve this. Thanks. Anthony, I have solar panels 3kw, and charge during the day to use them. That works fine now because it takes between 6 to 8 hours to charge depending on the state of the batteries. However I only get 2 to 3 kwh a day in the winter from my solar panels so I need grid power too. I don't think having a faster charger would help me, 'cos I just don't have enough solar power in the winter to do the job. You will know your system and whether it would be worthwhile for you.

Generally my Wife (who will be mainly driving the Leaf (lucky girl)), is usually out for about half a day, sometimes morning, sometimes afternoons. This leaves only about 4 hours of decent daylight left for the Leaf to charge off solar, which makes me think a quicker charger might come in handy. Though we will probably 1st see how we go with the Nissan supplied charger then make a decision.
Thanks.

Anthony, you also need to consider whether off peak charging would be better anyway, leaving you several uninterrupted hours every night, and use the solar for other things.

Yeah. There was no way I was willing to pay $4999 for a Nissan EVSE or $4799 for an Actew AGL charger or $5499 for a better place one. So like most other things, I made my own. After all the EVSE is basically a small circuit and a relay. Thanks to the openEVSE group I built my own 16A EVSE and have been using it for 17,000km without a single problem. Total cost was just over $500 code.google.com/p/open-evse/wiki/EVSE_LORDSn1per

So? Brian and Duncan, you can mail order the E-Station and plug it into a GPO 15A socket ( like the Level 1 charge cable from Nissan does ) and you have a level 2 charger?? Brian - love the portability as I am preparing to downsize. Wow - I owe a beer or coffee!!!

ravolt probably easiest you just go pick one up (the e-station shop is in perth ) you can also test charge before you buy www.recargo.com/sites/3146 IMHO you should not put a 15amp lead on a e-station because in theory they allow up to 32amps.. while your car will only ever ask for 15amp if plugged into a EV which supports 32amps you'll then be pulling 32amps through a 15amp plug. so if you want to put a plug on a e station it should be at least 32amp plug. (while yes there are no EVs that pull over 15amp in the country it should be safe by design not by chance) your other choices are import from the USA, or cloudninecars sell a 15amp charger for $950 +plus install.

*** Supercharging *** Thanks Brian for the test yesterday Saturday Just putting the info here for posterity Circontrol 16.994 amps - 15 amp non card 16.608 amps - 15 amp card; used for volt note the overload light is ON. Clipper Creek 14.975 amps - 15 amp ECS-20; charge fault message on Volt, OK on imiev and leaf BTW clipper creek make the 10A EVSE for the Volt. note that the clipper creek units DO NOT come with the yazaki charge coupler any more instead they come with the Delta type ie. not lockable one reason to wait for the next gen Leaf, it is supposed to have a lockable charge port. however, there is the charge port cover when charging in public $515 cos even with the lockable j1772 port on the next gen leaf, passersby can fiddle with the Chademo socket www.clippercreek.com/uploads/ClipperCreek%20ECS-15-20.pdfAttachments:

After using the stock EVSE for a few months we figured that charging at 10A was good enough so I took the cheapskate option and bought the Volt EVSE for $368. Charged the car fully last night without problems. Thanks for the bargain GM! Attachments:

hmm $368 aren't they going for $AUD350?
what does Nissan say about using a Holden product? will it be covered under warranty?
one quirky thing with the volt is that it defaults to 6A; this is for the lawyers. so one just has to remember to set it to 10A on the touch screen. Perhaps in the future there may be an option to set it to 10A all the time; unlikely in the US due to the lawyers.
This is one thing that LEAF & imiev owners don't have to bother with. Also if volt detects a 15A source, it will use it. BTW Volt pulls 14A.

I didn't think to ask why the website had it for $350, I figured it was the dealer mark up. Still got a good deal I think, it's only a few bucks.
Unsure about the warranty, probably something they'll try to blame if something goes wrong with charging, even though it's an off the shelf product that conforms to standard. That's when I'll call Dean. I'd be more concerned if I used OpenEVSE.

Excellent data, thanks g4qber
I take it that was an amp meter, does the amount of current stabilise over time ( a few minutes or a few hours), or was it pretty constant all along. Keep in mind a 15A circuit has a 20A circuit breaker on it (just like a 10A circuit has a 16A breaker)

Yes Duncan it is an ammeter Didn't stay long enough to determine if 17 amps stabilised. Only 5 mins for each evse.
I find it odd that the circontrol boxes allow 17 amps when the label says 16 amps.
Normally the circontrol boxes are supposed to be permanently fixed to the wall, so no one would know that they charged at 17 amps on a leaf.
Brian and I have them in portable format so we can use them out n about. Especially since they charge faster than the 10 amp nissan trickle charger that comes with the car

Patrick was suggesting that lower the voltage the higher the amperage eg. 210V
yesterday measured 3.790 kW 240.6 V 15.950 A
so still supercharging the LEAF.

tested on ravolt's LEAF today; thanks ravolt for opportunity to test.
e-station plain box = 13A, 238 VAC, 3kW e-station card box = 16A - supercharge, 237 VAC, 3.7 kW EVSEupgrade portable = 16A - supercharge, 236 VAC, 3.7 kW Holden EVSE = 9.9A, 238 VAC, 2.3 kW Mitsu EVSE = 10A, 238 VAC, 2.3 kW Nissan EVSE = 10A, 238 VAC, 2.3 kW
will be interesting to see what happens on Brian's e-station plain box; which has had its controller replaced and also Volt on Brian's e-station plain box.
my hunch is that they Ravolt's LEAF will supercharge and volt will charge at 14A.

may not be designed for Australian electrical standards. what is your thoughts on this unit Gabzimiev?

Post by gabzimiev on Jan 23, 2014 18:50:58 GMT 11
so there are 2 factors when importing from the USA one is they used a lower voltage and it's line to line not line to neutral, the other problem is the frequency. I've discussed the line to line vrs line to netual and can't see a big issue but the data sheet for that bosch has maximum voltage at 240V and Australia can go as high as 250V and often is. www.pluginnow.com/sites/default/files/EV13-135.pdf might be better looking a european ones as they are closer to our power standards legally it's use as own risk a sparkie can refuse to install them without a RCM mark. it would be illegal to resell and distribute without a RCM mark.

can't wait for Bosch to start selling in Aus to Aus specs. They already are trialling in Singapore. But I guess that they may be cautious. this is quite a good review for the US wall boxes. www.youtube.com/watch?v=Np2CPoWJzhkgives you an idea on how big the Bosch unit is.

I actually like the Siemens unit the remote activate and remote charge lights are good as well as the reduction of power to 10 and 16amps with and internal switch is a clever idea.
Next time I see a siemens sales rep i'm going to have to ask if they are bring them out.

The US has 208 and 240 volts dependent on distribution. Eu is 220-230 volts. The EVSE box is just delivering power to the EV after appropriate handshaking. I would suggest that the EVSE control circuit in most cases uses a switchmode supply which on average take 85-265 volts. Given that, it is again just a controller to deliver AC power at a confirmed amperage to the EV on board charger. I do readily acknowledge the certification issues in this country, I understand the safety premise behind them. But if the device carries a certification of EU, UK or US standards, Im reasonable happy to use the device here. Home built is another story.

My hunch was correct using Brian's EVSE With replaced module, Volt charges at 3.3 kW 216VAC 15.555A
Brian's LEAF on evseupgrade EVSE does the same as ravolt's Super charging 3.7 kW 223VAC 16.959A
Thanks Brian

Given that, it is again just a controller to deliver AC power at a confirmed amperage to the EV on board charger. see that's the problem you've made an assumption here not saying it's not wrong but they could also be using a AC -AC transformer rectifier to DC then a linear regulator. which will on overvoltage over heat. also read this section on the effects of the changes of frequency between 60 and 50hz sound.westhost.com/articles/50-60hz.htm#s40 this is why clipper creek have international models of EVSE that are designed for 50hz www.clippercreek.com/store/product/ecs-international-plug-connected/ is 50/60 and www.clippercreek.com/store/product/cs-40-e/ is also 50hz. the Bosch data sheet is lacking

odd pricing on website holden evse is RRP $350 went to melville holden today quoted as $415 went to shacks holden quoted $425, but this could be a mistake cos the guy originally thought I needed a $1600 spare part.
