Parts, Mods And Hacks / Re: Elcon TC HK-H 1800W Charger (on Zero Motorcycles 2013+)
« on: September 16, 2018, 02:31:47 AM »
Thanks for sharing this Shadow! I'm following your progress and will likely be following in your footsteps...

So you went the enable signal route, can you post a schematic and a pic of how you wired it up? I assume you connected it to one of the signaling pins on the anderson connector to keep the contactor closed, correct?

Was the CANbus option even feasible? Was there an option to order the charger with the protocol to talk with the bike straight out of the box?
The AliExpress (https://www.aliexpress.com/item/3-3KW-Elcon-TC-Charger-for-Electric-Vehicle-for-LiPo-LiFe-Lead-Acid-battery-pack-for/32855919611.html) supplier states that they can work with most BMSs but I doubt Zero's is one of them :-\
I saw a post with someone using a ThunderStruck EVCC-Basic Controller but that is considerable added complexity that I would prefer to avoid, so I'll likely be going the enable signal route.

Are you using these in tandem with the stock charger?

P.S. for $220 and up you could replace your onboard with a suitable TC Electronics charging module but there is some similar DIY factor like what you are doing now. I bought an 1800W charger module from EVComponents (link to China seller) and plan to do just that with my own bike to shave some weight - it's low enough power output that you don't need any fancy charge algorithm. When I have time to mess with it I'll document how it goes, but so far I found it to be an acceptably rugged construction. Just trying to find a schematic how does the bottom face connector get documented when I only know English language and no idea how to ask for the wiring diagram from the seller. For twice the cost Electric Conversions (Elcon) of California has the same exact product but with support and programming capabilities. I've heard it is either charging enable or it is CANbus... how to test what it is?

Thanks for the heads up on that Shadow. Could be a good option. I'll check it out.

So I connected the meanwell stack to the back of the battery with power through an anderson and no signaling, I plugged in the ground connector of the meanwells instead of the stock charger. I keyed on the bike and then plugged in the charger, I was looking for a sign of life (green charging light) but was only able to see that it was charging through the app. I left the bike on for the duration of the charge.

Started out at 45% which is where the stock charger left me. At around 65% I went to eat lunch, when I come back I see the dash flashing all 8s :-\ disconnected the charger keyed off the bike and restarted the process. All of a sudden the SOC is at 97% but the battery voltage is 113... I just let it do its thing for another couple of hours (trickled nicely) and I'm up to 100%. Haven't seen those beautiful digits in a long time ;D

Couple of things:
1) Under what error conditions does the dash flash all 8s? Could it be an error that the bike is on for a long time with no rider input?
2) The cell balance is currently 5mV which is higher than the 2mV that I started out with. Anything to worry about?

When my DC2DC died, it was on and off (drove me nuts) for a couple of days until it was just off...

Replaced the DC2DC and walla problem solved.

Yeah I'll keep you posted on that.

I assume that it's the charger since there is no error on the BMS and when I disconnect the charger and wait a little it will resume for a little while, increase the SOC by a few % and then stop again. Funny, sometimes it stops at a certain SOC (well below 100%) with a solid green charge light showing as if it completed charging but doesn't cause the dashboard to flash all 8s.

So I guess I'll go with keying on the bike during the aux charge instead of plugging in the stock charger, as MrDude said I'm kind of worried about the stock charger malfunctioning and cutting off the charge prematurely...

The stock charger on my 2015 SR is dying a slow, cruel death...
Started with a flashing dash and a max SOC of 98% and over the course of a couple of months can now only bring the battery to 54%.

This is actually a replacement charger after the original failed about 6 months into life.

I have been trying to procure a diginow charger as a replacement but due to a huge backlog (wishing Brandon a quick recovery!) and import restrictions, I still find myself with a bike that has a slowly decaying 60 km range...

Which brings me to my request for help, I have access to a 2013 OEM charger and would like to use this as a bridge charger until I can get a diginow. The 2013 charger (A stack of 4 Meanwell HLG-320H-54As) was originally designed to work in conjunction with the CCU. I am planning to re-purpose the charger to be used as an Aux charger through the back of the battery by installing the SBS-75x connector to the C+ and C- lines coming out of the charger. There is no signaling available.

I plan to still use the stock charger to initiate the charge cycle and close the contactor then plug in the aux charger to supplement the charge hopefully allowing me to increase my dismal SOCs.

Is there anything that I need to watch out for? I'm a little worried that without any signaling the meanwells could go rogue especially with the malfunctioning on-board charger. Would it be better to just key on the bike (I charge in my garage so I can leave the bike on during charging) and not plug in the stock charger?

I was looking for a towing solution for my UTV and I came across this:


https://www.amazon.com/TMS-MotorcycleStand-SC1307A-Motorcycle-Trailer-Carrier/dp/B005XDM0XO

which got me thinking...

Keep your rear wheel on the ground, set regen to max, disable your abs and you should be able to recharge your bike while transporting it, no?

Zero Motorcycles Forum | 2013+ / 3D scan of partially disassembled Zero SR '15
« on: December 20, 2015, 10:57:19 PM »
I've been toying around with my Kinect sensor and some SW for some projects that I've been working on (to be posted in subsequent threads) and did a scan of my partially disassembled bike. It's a bit rough around the edges but it allows me to make the measurement I need to fit some parts that I am trying make for the bike.

Attached is pic of what the scan looks like, it can be visualized and manipulated using a free software called Meshlab (http://meshlab.sourceforge.net/).

For those interested in accessing the scan I put it in my public dropbox, you're welcome to PM me for the link to download.

Awesome, I'd say that's as low temp as you can get. Never noticed that the steering limiter is also up top! How convenient...

Thanks for the info!

The bike looks great!

I am considering installing a front cowl fixed to the frame of my 15 SR (not to the forks). I was curious how you got the front fairing stay onto the neck of the bike. Specifically, how were the fairing stay tabs installed? Was it done by welding (TIG or oxy acy), aluminum brazing/soldering, metal adhesives or some other process?

I'm looking for a low temperature process and I've seen some processes for 6061-t6 aluminum (what I think is the grade used by zero) that maybe very applicable but it would be great to get some feedback from someone who has already done it.

Zero Motorcycles Forum | 2013+ / Re: 2015 SR rebooting and now won't charge
« on: October 28, 2015, 01:58:21 PM »
I've got reboots when stopped and at low speed, I always found it puzzling that it hasn't yet happened at high speed (and thankful for that)... I was told to make sure that the charger is disconnected, the contactor disengaged and the display is blank before starting the bike but it didn't help, still got reboots. My dealer recently updated the SW on the bike (about a month ago), it rebooted immediately afterwards (while still at the dealer) but hasn't done so since.

I previously had a problem with the charger as well (about 9 months ago I described the problem in detail in an earlier thread) but after being replaced I haven't seen any charging issues.

Good luck

I'm having trouble coming to terms with those Dyno run data, Doc.

If the bike is electronically limited to 6000 RPM which corresponds to 160 kph then according to the graph at 80 kph (3000 rpm) we should start experiencing a severe drop in acceleration. That has not been my experience after testing my 0-100 times (I attached a graph that I posted on another thread), wonder what could be the cause of the discrepancy?

If the dyno run is accurate, it would make a strong argument for a gearbox...

ctrlbrn thanks for posting that! it will be a good point of reference.

I need to get my hands on a stand so I can do a run and compare.

Did you do anything similar to that prior to getting the thermistor taken care of?

I just don't get the stubborn lack of fairings... :o

It just seems like such a no brainer - increase range (especially highway which is needed most) and improved weather protection with minimal design and manufacturing costs and only a minute increase in weight.

The only time it happened on a cooler day was when a guy pulled up next to me at a light, hollered at me about "is it electric??" and then bugged me into drag-racing him through the next few lights (for some reason traffic was really light). After about four one-block races the overtemp light started blinking and I started acting my age.

I understand that the overheating can be mitigated by slow and easy riding but I didn't pay the premium price for the SR only for the red color and the extra R in the lettering ;) I want to be able to be able to exploit the performance of the bike to its fullest capabilities and if there is a malfunctioning component that is limiting me from doing so, I'd like to get it taken care of. As it stands now, I now have a trade-off between heating and range since the bike doesn't shed heat when using full Regen (even only when set on braking), I keep Regen to a minimum and pay for it with reduced range while still hitting the overtemp limiter frequently.

ctrlburn, so just to clarify, after having the thermistor replaced the bike no longer suffers from overheating (or significantly less so)?
