Assuming you have a zero 11.4 S how would you set it up for touring assuming you don't want to have to wait too long at any given stop? How many miles per hour could you cover? Is there a limit to how fast you can charge the batteries without damaging them?

I have seen several 'quick charge' threads but if I recall none about the newer 11.4's or 14.4's and if I recall I would have to build an enclosure for them since they are not sealed. It would be nice to see a list of parts down the the adapter for the 11.4 an 14.4 models.

http://electricmotorcycleforum.com/boards/index.php?topic=3308.0 (bottom of thread last 3 posts shows BDSThw's setup)

I also found this thread talking about charging vs range options http://electricmotorcycleforum.com/boards/index.php?topic=3009.msg14592#msg14592

For a 11.4 to charge in 1.4 hours would require 8Kw but I don't know if you can get that many watts out of one charger.
for the 14.4 it would take a 10.2Kw charger.

I did my Northern VA down to Ashville NC trip in a day and probably wouldn't ride longer than that in a day given how sore your butt can get even with a nice seat. It was about 500 miles and took about 9 hours if I recall. Now I plan on streamlining my bike but I don't know how much of a difference in range I will get but I have been told to expect a 50% increase in range. So I assume my range would be around 130 miles at an average 55mph. This means I would do 500 miles in 13+ hours assuming a 1 hour charge time for example.

I realize there may not exist the answers to these questions yet but I figured I would post up to see what people thought to find out what is more efficient for the 2013+ models.

[protomech]

Using CHAdeMO, Zero charges the 2013+ batteries at approximately 1C. For the S and DS bikes, this can be limited by the maximum CHAdeMO DC charger output (some small CHAdeMO chargers limited to 50A, others 100A, a few are 125A).

Zero may also restrict the charge rate at high SOC, high cell temperature, etc. It will be difficult to get access to these sensor inputs.

Most J1772 EVSE will supply somewhere between 30A 208V AC (6.2 kW) and 32A 240V (7.7 kW). Assuming 90% charger efficiency, this gives you 5.6 to 6.9 kW per EVSE. Call it 6 kW DC.

You could tap multiple J1772 EVSE to increase your charging power, assuming there is more than one EVSE available. Terry Hershner does this to good effect.

Note that even though riding more quickly is less efficient, it will reduce your overall trip time as your charging power increases.

For example, with a stock ZF14.2 bike, times to ride + return to the same SOC

Riding 50 miles @ 55 mph takes 0.91 hours. Charging options:
1.3 kW (120V AC) 4.62 hours, 5.53 hours total
6 kW (J1772 x1) 0.98 hours, 1.89 hours total
12 kW (J1772 x2) 0.49 hours, 1.40 hours total (35.7 mph total)

Riding 50 miles @ 70 mph takes 0.71 hours. Charging options:
1.3 kW (120V AC) 5.56 hours, 6.47 hours total
6 kW (J1772 x1) 1.18 hours, 1.89 hours total
12 kW (J1772 x2) 0.59 hours, 1.30 hours total (38.4 mph total)

I would expect probably a ~20% improvement in range with typical bike fairings, or 60-80% improvement in range with a full slipstreamed fairing like Terry's.

Assuming a 70% improvement in range to 150 miles @ 70 mph = 59% reduction in power. You'd probably charge every 75-100 miles instead, but let's say 50 miles just for comparison purposes. Charging options:
1.3 kW (120V AC) 3.27 hours, 3.98 hours total
6 kW (J1772 x1) 0.58 hours, 1.29 hours total
12 kW (J1772 x2) 0.29 hours, 1.00 hours total (50 mph total)

With a sufficiently streamlined bike, a 500 mile trip would take approximately 7 hours to ride, with 4 stops to charge for about 40 minutes each. Total time around 10 hours.

"I am sorry officer I was just trying to decrease the overall time it took me to get to my destination, including charge time, by riding faster." LOL

That is 500 miles on a highway where I wouldn't get pulled over for going 70mph would take around 10 hours. I think half of our trip was backroads because who wants to be on a highway all the time? =D

Now on to the part I had to google, the coulomb you mentioned. The C-Rate I thought only indicated the SOC and how long it would take to discharge a battery. In another thread I saw that the C-Rate zero states for our battery is 0.5C, or meaning they can discharge up to half their charge in an hour. That doesn't seem accurate though.

Help me here if I screw this up. A 11.4 bike has an effective storage of 10.0 as stated by zero. So at 0.5C the bike can discharge  @ 5kwh safely. At 70mph the bike has a range of 70 miles which is equivalent to a discharge rate of 1C right? Since it takes the full 10kwh to travel 70 miles in one hour? For 55 mph the discharge rate would still be 0.647C an hour. I know 1C is 1Ah but without knowing the voltage of the bike I am not sure if I am making the connection required to understand what your talking about.

Not that it matters too much as we dont have CHAdeMO chargers here lol

The bike has the DigiNow dongle on it and I have been told restrictions have been lifted for rate of charge.

I just returned from an 80 mile ride on mostly secondary state highways with an average speed of about 50 to 55 mph.  I used 9.3 kWh of power, which will likely take me about 7 hours of recharging, according to my display.  Without being able to fast charge, your tour is likely to be taken in 200-mile days - provided you stay off of the freeway as much as possible.  For now, I will do my touring on my IC motorcycles, which is just fine as they need a workout now and then as I am putting about 700 miles a month just tooling around on my Zero.

After talking to Terry a bit today he suggested I look at the stuff Electric Motor Werks is doing. Seems likely they will be coming out with a 20kWh CHAdeMO kit and they already have a 12kWh kit available I could throw in a weatherproof enclosure on trips.

I do at least 1k a month on my bike, 500 mile day trips on weekends (called day trips because I leave at sunrise and get home near 11pm lol), and 3k mile week long trips when i can.

I use to build electrical laboratory equipment so I think I might actually build out a EMW kit, just don't know which yet ^_^ Then I will just have to work out adapters for J1772, Nema 5-20, and Nema 14-50 to their system.
