Sorry if this has already been answered on this thread,but im considering buying a 2015 Zero S , but I need it to be able to do 114 mile round trip on my commute to work.Would be greatfull for any advice on my options for charging.The Nissan dealership across the road from work has a charge station for the leafs and have said I can charge there,what would I need to do this ? Can I just buy a special lead for the onboard charger,or do I need the power tank or a fast charger ?

Either of those should work. The power tanks isn't for charging but an extra battery brick to give you some more range. You can also choose for the charge tank, you loose to option to get extra range but you'll charge significantly faster.
To charge at a charging station you'll need an adapter but that's it in most cases, but have you already taken a walk on your own parking lot at work? You might encounter a stray outlet somewhere that you can use, that would make it much easier.

I have a 2016 DSR and have a 100Mi round trip commute.  I am lucky in that I have both Level-2 and outlet charging available at work.  On my bike, if I take the highway (35 Miles at 70 MPH and 15 Miles at 45 MPH), I arrive with 30% charge remaining.  If I take the back roads (45-50 MPH), I arrive with 50%.  So a round trip might just be possible on the back roads, but it would be tight.  I think you'll need to find a way/place to charge at work for a 114 Mile round trip.

Do I need a quick charger to plug into the charge station, or do I buy a special lead that plugs the onboard charger into the station ?

I have a J1771 adapter that I purchased from TusconAV for $145.00.  It has two appliance cords coming out of it. and the J1771 coming in.  I can use one to use the on-board charger only, or that and the second one to power my QuiQ charger (I have 1x QuiQ).  I get about 2500 Watts of charging with both chargers running.  That's how it works with Level-2, for the standard outside outlet we have near the parking lot, I just use an extension cord.  Even with just the on-board, I can top off from 30% to 100% in about 6 hours (I work longer days than that!).

If you were to purchase a Charge Tank, you would just plug the J1771 in directly to your bike, I think you get 3.3KW charging with that setup.

I am lucky that we have 8 free Level-2 chargers in the parking lot at work, and we have the external outlet that I have permission to use.   The level-2 slots are hardly ever in use (I've never seen more than 2 in use at a time).

The DigiNow is a much better option because it is a faster, more powerful charger, its modular and you can fit 9.9 kW in the tank area + the 1.3 kW onboard with the use of 2 J-plugs.

Zero has to meet strict world wide EMI requirements and it is hard to do that with other hardware.  Don't blame Zero, blame the requirements (European, I believe. )

Here are some numbers (updated):

Charge Tank= 2.5 +1.3 kW
Charge Tank Cost + Install =~US$ 2195
Cost per kW =US$ 578/ kW
95% Recharge Time 13.0kWh = 2.9 hours

DigiNow 3.3 +1.3 kW
Charge Tank Cost + Install =~US$ 1755 (Install is easy/ free)
Cost per kW =US$ 382/ kW
95% Recharge Time 13.0kWh = 2:21 hours

DigiNow 6.6 +1.3 kW
Charge Tank Cost + Install =~US$ 2710
Cost per kW =US$ 343/ kW
95% Recharge Time 13.0kWh = 1:22 hours

DigiNow 9.9 + 1.3 kW
Charge Tank Cost + Install =~US$ 3600
Cost per kW =US$ 321/ kW
95% Recharge Time 13.0kWh = 0:58 hours

Nice analysis Killroy!!

Yes Testpilot1 I would get a 2016 or 2017 SR if you can because it will have a 13.0 battery vs the 12.5 in 2015.
It will also have much better power density and the IPM motor

The 2017 will come with a stronger belt and have even more power, so the 2017 is advised if possible.

And like Killroy suggested, go with the 6.6 Diginow supercharger in the tank to take full advantage of the J1772 at the Nissan place across the street.

Here are some numbers:

Charge Tank + On-board Charger= 3.8 kW

DigiNow 6.6 kw + On-board Charger= 7.9 kW
Charge Tank Cost + Install =~US$ 2710
Cost per kW =US$ 343/ kW
95% Recharge Time 13.0kWh = 0:52 hours

95% Recharge Time 13.0kWh = 0:37 hours

Is your math off or am I?

How do you get less than 1 hour charing time with 7.9 kW ?

But the concept is correct;)

its because hes not showing 100% charging time..
All lipo batteries get full current charging until they hit the voltage max at that current... then the voltages is held there, so logically the current starts tapering down.  So the very last bit of charging on the battery takes much longer than the rest below it.
the higher the peak charge rate, the sooner it starts tapering down.

The digiNow table with similar numbers lists these times as charging to 80%, not 95%. Still, charging with a 7.9kW source for 52 minutes simplistically yields 6.85kWh, which is only 53% of 13kWh. http://diginow.it/super-charger-for-zero-motorcycle.php

Great response guys thankyou, very informative .......... I'm not technically minded like a lot of you, so bare with me. So if I just got the suitable lead to plug the onboard charger into the Nissan dealership ( think the class 2 is 22kw ) , would it charge any quicker than my home 240 V supply ? Or do I need the diginow  ?

22kW, you must also be located in Europe then? But no, when using only your kettle plug the bike will always charge at the same rate using the on board charger.

I got the numbers wrong before and I corrected them  I'm just pulling from Zero and DigiNow and I was confused with 0-80%, 0-95% and with and without the 1.3 kW onboard charger. 

With the charge tank, when you plug in the J-Plug, does the 1.3 kW charger get used too?  Is the total 2.5 kW with the on board or is it 2.5 kW +1.3 kW the total? 

Note that the 0-95% times on DigiNow are without the 1.3 kW onboard, so if you plug in the onboard, which could be a separate step, then it will go even faster up to 1C or the limit of your charge station.

Yes, charge tank will use onboard for 3.8kW total.

With the charge tank you get 3,8kW from the books, but in real life it's more like 3kW. Been there, done that, have the logfiles
Also, with 6,6kW charging power the bulk fill rate is approximately 1 minute per % so 20-95% takes 75 minutes. Also, been there, etc.
