Welcome to the Forum seriousam! Can't advice on level 2 chargers as I don't use them. I use the EVSE that comes with the LEAF. However the thread 'Do I buy that Leaf?' has some info. that might help you.

Welcome Serious Sam,
Good to see that you are thinking of swapping the bazooka to a LEAF as well :-)
I am planning to get the same Bosh unit, it is supposed to be a very good unit and is probably the only decent priced one. I am trying to source it directly from Bosch in Germany but it will take a few weeks. If you still haven't bought by then, then I may be able to give you more advice.
Phoebe, the Nissan EVSE is level 2 as well as others have said it, too. Level 1's take like 20 hours to charge (ouch!) and we don't have that problem here being a 240V country.

If the unit is not designed for 50hz don't buy it American is 60hz and that's the target market for the Bosch unit... also any licensed sparkie has the right refuse to install it as the Bosch unit is not legally allowed in the country. All electrical devices in this country are required to carry a RCM mark and if required be EMC tested. it may invalidate your home insurance but I haven't really read the fine print.

Haha awesome! Someone got it!
Sounds good! Let me know how it goes, I would love to know if it is worth buying since all the others I've been looking to buy are at least $1,500.
Yeah gabzimiev, that is a good point. It doesn't state whether it works at 50hz or 60hz, I assume that it may be able to switch between them similar to power supplies in computers you can switch between 240v or 110v.

It doesn't state whether it works at 50hz or 60hz, I assume that it may be able to switch between them similar to power supplies in computers you can switch between 240v or 110v. the problem with the assumption is that the part which needs the transformer to produce the 12volt is for signalling. and if it's 60hz transformer and that creates noise on the 12volt line or voltage variation then it's not going to be able to handshake with the car. the EMW juicebox www.emotorwerks.com/products/online-store/product/show/44-emw-juicebox-level-2-15kw-ev-charging-station-kit-or-assembled-unit atleast you can see that the transformer they use is a JMD20-B from the assembly pictures this has a wide frequency and voltage input range it produces 15volts which they then are using a linear reg. to bring it down to 12 volts so you will probably get a very clean power output from that.

Do you need to charge your leaf at 15amps
If not then cheapest 10a option is the Holden volt evse $370

I believe if I was going use 15a, I might just stick with getting a 15a wall socket or the device from Jaycar that has a fuse in it, and stick with the cord that comes with the Leaf (I am aware it doesn't use the full 15a, it just has the 15a earth pin). The point of my original question was to find out if getting a 30a EVSE for about $800 was too good to be true, since E-Station and Origin both have their devices two to three times that price.

Welcome to the forum! Would be worth comparing the charge times. Seems like the 10a chargers only take about 20% longer to charge and if you mainly charge overnight then you have time to spare. Phoebe, how long does it take you to do a full charge on average using the supplied 10a? For comparison, I have the Origin Chargepoint 30a www.originenergy.com.au/3814/Products-servicesand it seems to take between 6.5 and 8 hours to get a full charge. I'm guessing the supplied EVSE isn't too far behind that. But to answer your question about too good to be true, no, it's not too good to be true since it's in a different product class. The big-ole Origin Chargepoint is expensive because it has a lot of unnecessary bells and whistles like automatic back to base firmware updates, a card reader for using professionally and other gizmos. All you really need is for something to feed the power, and that's what the cheaper ones do. I only have the Chargepoint because they gave it to me. That's me in the product videos in the above link.

It normally takes me 6hrs to charge, but I usually still have 40kms left when I do that. The only time I've had nothing left it took eight and a half hours. If you are doing that overnight that is no problem.

there are 2 reason to get a wall charger over the provided EVSE.
10amps vrs 15amps charging at 150Wh/km so 15Kwh to do 100km
10amps is a 2.4kW charger so 15kwh would take 6.25 hours 15amp is a 3.6kW charger so 15kwh would take 4.16 hours
so 1.5 times faster to use a 15amp charger.
the other is connivance of not having to remove the EVSE from the boot if you like to bring it with you when you leave the house... mine just stays at home.

To me the time difference isn't really a big deal unless you are charging during the day and waiting for it.
The second argument, pulling the EVSE from the car to use it is the real one, but you can get the Holden EVSE for $375 and bolt it to the wall.
If the only difference is another 90 minutes of charge time overnight, I would be cool with that.

Nissan seems to charge $3410 for a replacement 10a evse the last time i checked. They might have a deal with chargepoint origin. Mitsu charges $1600
Charge-amps have portable 6,10,16 evse for $us 750 Evseupgrade have their 15a portable for $us 1027
Can't wait for Matt Lacey to assemble his open evse unit.

This one is 7.2kW with 30a (Although the Leaf would only use 6.6kW) but increased time is still increased time. I thought it made sense if you ever needed to run home a few times over a weekend and you need to charge it quickly to get going again. I can't imagine this would happen too often, but if you ever needed to go further than the current charge in the car, you can quickly plug it in and get 50km in an hour or whatever. Yeah I thought having the wall charger in the boot of the car would lessen the chance of forgetting it; meaning, if you get stuck somewhere you can plug it in some where enough to get yourself home, or even at a mates place. I am interested to see how someone goes with the OpenEVSE.

you in the right country ? Australian leafs max out at 3.6kW. you might be looking at the UK spec leaf even then the 6.6kW is an optional extra

We're still stuck with the original LEAF, not the improved model sold overseas. What we have as the 2013 model is old stock, when I bought mine in June last year it was an April 2012 build. Nissan must have brought over more than they thought they could sell. People have asked Nissan when they'll start selling the upgraded one here but as far as I know there hasn't been any confirmation (probably trying to avoid the Osborne Effect!). We bought the LEAF knowing it wasn't the latest compared to overseas but if you compare the difference between the two and can live without the improvements, it's not really that big a deal. I have happy memories of playing Serious Sam on a LAN with my high school buddies. It was manic!

Welcome to the Forum, Serious Sam. My experience is I bought the E-Station unit, and have been very happy with it. Rather than have it hardwired to the wall, I ordered it with a 15 Amp plug, and modified the unit so that it could either hook on to a wall mount, or un-hook and come with me for quicker charging than the supplied ' back-pack ' EVSE. My E-Station unit has been measured charging the LEAF at up to 18 Amps. We have never yet been caught waiting for the charge to finish so that we could get to our destination ( and back ).

Still happy with my UK clipper creek 15amp. Have built an EMW Juicebox for a backup at work.

Meant to say to buy the European Clipper creek, as it is 50Hz 230v. The specs go to 265 volt. The things just work well and are very robust.

thx 4 info.
do you have a 15 amp rcd/cb on the 20 amp circuit?
would be interesting to see what happens when you plug a volt into your EVSE. my volt creates a fault on the clipper creek EVSE, but at least it didn't trip the House RCD.
I sent mine over to to marty11 to test on his volt. still with marty11 since the only EVSE albeit wall box that works reliably with my volt are the circontrol wall boxes. and even then, the 16A non card unit only negotiates a 10A connection. all in all my volt is very fussy. I treat it like a mac. all planets have to be in alignment to work correctly.

I got some bad news from Bosch in Germany. The Bosh EVSE unit is not being sold over there. I thought Bosch being German, I can get it directly from them with European specs. From what I am hearing EVs are not very popular there at this point. I can understand why. Trying to run it at 200km/h on the autobahn (if it could go that fast), it would not make it to the next freeway exit Given the speeds they can drive at, EVs will not be used by the Germans, I think. I will have to investigate the American unit further, but also contemplating whether to assemble the OpenEVSE instead.
