So, for my bike, I have a 1500W charger that runs off of 120V, with a MiniBMS (well, i will have this when i finish).

I'm also getting a Nissan Leaf, and will have a AeroVironment 220V 30A charger (http://evsolutions.avinc.com/products/at_home/#charging_at_home_a) for the car. This charger has a J1772 adapter. Can i use this on my bike? I know places like currentevtech sell J1772 adapters (http://currentevtech.com/SAE-J1772-Socket-p164.html), but will i be able to use this charger for my bike as well?

Yes. Ensure you connect the receptacle pins correctly to the bike charger, but the J1772 has 240V single phase and 120V single phase in the plug. You should be golden.

BTW, have you been able to find any other places selling the receptacle?

can the 1500W from Elcon charger run off 240?

Frodus, i think so, but i don't want to do that (i think). it's not really an elcon. it's a no-name chinese charger i got from bmsbattery.com: http://www.bmsbattery.com/index.php?main_page=product_info&cPath=5_27&products_id=36&zenid=e84f8e40ac9377fd06ae388755f432c0. Specs at http://www.bmsbattery.com/pdf/w1500.pdf.

I think from your comment and from sean's comment, i think i just realized where my thinking was faulty... I thought that the AV (aerovironment) "docking station" was a charger itself. My thinking was that using the standard 120V charger that i bought would be for normal use, but when i was at my house, i could use the AV "charger" to charge faster. The problem here is that the AV "docking station" is not really a charger, right? The Leaf must have its own onboard charger that can get charge from one of the three possible inputs (120V "trickle charging", 220V "L2" standard charging, and 440V "L3" quck charging).

So, now, i wonder...can i have the charger i bought be hooked up to both 120V and 220V somehow? Should i even bother? a 7kWh pack should charge overnight at home using the 1500W 120V charger, and that's probably all i need anyway...

BTW, What's the use of those docking stations anyway?

I used the 3000W "El Con" charger from BMS battery this year. All BMSBattery did was scratch off the "El Con" on my charger. Why did they do that....... I have no idea. But it did work fine on 240VAC

How were you talking about hooking up the charger to the two voltages? An additional charging port where the extension cable would determine the voltage or through the J1772? J1772 will be pretty definitive, so maybe a switch if you go that route.

Under 'details', the link you provided says "Model : W1500, Manufactured by: EcityPower"

what is the input voltage range?

If its a 1500W charger its not going to charge any faster off 240V than it will of 110V, right? So, probably not worth the trouble to tap into the L2 input of the J1772 since it has both L1 and L2 inputs, right?

From green.autoblog.com

"Nissan's partner to make home-charging for electric vehicles (EVs) a reality is AeroVironment (AV), a leading producer of EV charging units. The partnership is putting the finishing touches on a Nissan-branded home charging unit marketed at buyers of the Leaf all-electric car, but the charger is not model-specific. As AeroVironment's vice president of EV solutions Kristen Hensel remarked:
It's a very good charger, it will work for any car. So whoever owns the home and owns the Leaf, if they sell and move out and a new EV owner purchases that home, the charger will work reliably for years."

its still just a power drop, no charging stuff built in.

its a typical industry miscommunication....

Unless I've misunderstood what I have read about the J1772 connector, it has contacts for both 120 and 240 but that doesn't mean they have to be used. If you have a vehicle set up for both L1 and L2 charging it could do either, but if you are set up for L1 and you plug into a station that only has L2 you aren't going to get anything. The real question is whether all these new "L2" stations are going to be L2 only or if they will be set up to offer L1 as well, and are just being called L2 because that is the highest level they offer.

Something also, that I noticed about a week after I ordered my 86v Chennic charger....
Their chargers are rated by watts output, and you can choose how to have them configured for the factory (i.e. lower voltage, higher amps, or vise-versa) and you can also choose which input range you want. Input ranges are 100-120VAC, 220-240VAC, or for only a few dollars more (like $4 if memory serves) 100-240VAC.
For those in areas where they are likely to have public charging stations in the future, it looks like a very nice option to give the flexibility of charging L1 or L2.
