Hugues replied to the thread New PID's for Orion BMS and possibility to read Curtis motor data with Torque.
" Finally, i got the whole thing to work

On my Torque dashboard, i now have both the BMS and Motor/controller data. I cannot see the data in the 3rd party screen on the BMS PC interface, but the PID are anyway available in Torque.

So a little recap, for those interested:

- I'm using this CAN repeater/isolator:
http://www.bb-elec.com/Products/Seri...Converter.aspx
which i bought here:
http://www.ebay.ch/itm/282312297142?...&sojTags=bu=bu

- You need to get the Curtis OS files from HPEV to flash your controller if you do not see the BMS menu in your Curtis software. Simply turn on the BMS option

- I connected the CAN H and L wires from the controller on the CANOP side opposite to the side with the power input. I did not connect the CAN gnd wire

- I connected the CAN2 H and L wires from the BMS on the CANOP side with the power input. I also connected the shield of the CAN wire to the CAN GND. I used the same 12V supply as the BMS to power the CANOP

- The list of PID in given in the first post of this thread, you need to define them manually in Torque before calling them from your dashboard screen.

- You can see my Curtis and BMS printscreens in this file:
https://drive.google.com/open?id=0Bw...HpFZGtqUC0xSFk

Nice to see the motor amps and rpm, controller and motor temp, Curtis fault code, you can also show the speed of the bike by using the rpm value and divide by the appropriate factor, before i was using GPS speed, not always accurate especially at low speed.

ALso, with the new OS version and this CAN connection, the controller receives the battery cell voltages and SOC and can reduce power in case of values out of range. I still need to check if i have set this right.

thanks all !

Enjoy ! "

" ok,
so i managed to upgrade my controller with the flash file sent by HPEVS and set my parameters back, everything works normally as before.

So i got the BMS option in the menu, i turned it on and tried to set the parameters as far as i know.

But the BMS still does not receive the CAN data from the controller, at least i cannot see it in the Orion screen.

I attach a link to a pdf file showing printscreens of the relevant screens of my BMS and all the Curtis parameters:
https://drive.google.com/open?id=0Bw...HpFZGtqUC0xSFk

If anyone spots something not right, please let me know.

When i configured the BMS to add CAN connectivity with Curtis controller, it added some CAN messages: 0x300, 301, 602 and 601, we can see them in my second printscreen. 300 and 301 if i'm not mistaken send data to Curtis, then 602 and 601 looks like they should receive data, but it seems to me their configuration is empty, but maybe it's normal that way. In 3rd printscreen we don't see any data for the motor. And in the 4th printscreen we don't see data for messages 602 and 601 but we see 300 and 301. So something is not right. Maybe i still have a connection problem, but i don't see it.

I will contact HPEVS to ask guidance for next steps. "

" So,

I've been in contact with HPEVS, they sent me a file and program so i could flash my controller to get the new functions like BMS,...and they sent me a .cpf file with all the parameters.

I made sure i backed up my current controller parameters, also taking printscreen of each, i also had my previous flash file.

So i followed HPEVS instructions to flash my controller and upload their parameters file, all went well.

Of course some of the parameters i had to adjust to my build, like "invert 2 phases" to get the correct rotation direction on my motor, this i could change and save.

But some parameters like the 0 rpm throttle voltage was set at 0.3 volts and mine was 1.05 volts, so i can change it on screen and it's taken into account, but if i close the controller and power on again, the parameter is not saved. Problem 1, can't run the bike like this.

But some other parameters i can't even change on screen, like the % to set my contactor voltage, it's blocked at 48% which is about 48 volts and i need 24 volts. Problem 2.

A bit puzzled by this, i never had any version of my controller that blocked me from changing some parameters.

I trust HPEVS know what they are doing, so the problem is probably on my side. If someone knows why i cannot change/save some of the parameters, please let me know. It's Saturday morning here and HPEVS is not back online till monday. Crap.

So i re-flashed my controller with my previous settings and cpf file and all is fine. (Note: i cannot load my cpf file on the new HPEV system, says it's incompatible).

UPDATE: I found the problem. The new parameters list provided by HPEV in the flash file have a new section at the beginning which contains some of the parameters found in the usual list, and these have priority over the ones below. So you have to set them first, like throttle voltage and so on. Now busy re-entering my setup. "

" Hi all
The low quality can be accepted if balanced by low costs, but when it involve our safety it is very very important extensive controls on every product.
Non only Lithium batteries are involved in fire risks, luckily at today we (me and my friends) don't have experienced fire on batteries, but we had on controllers.
We have some pictures of "made in USA" burned controller
Attachment 7292

I have no doubt about good quality of this controller. But It had many years of use (about 7) without too much care.
I want to say that talking about electric vehicles there are risks even with products of good quality.
Imagine how much risk using products of poor quality.

One of my friend have 3 Quantya Freeride and Strada, he purchased used some year ago (I think are 2009/2010 models).
He use it for rent in his farm near Milano and have no time to maintenance it so the bikes are often abandoned as they are after the use in the Woods.
All his motorcycles have had problems with the batteries, but only involved the BMS, not the battery cells.
The main cause of the malfunction is the minimum current consumption of the BMS.
Leaving the battery discharged for several weeks, the minimum comsuntion of the BMS discharged some cells lower to 2.4/2.5 Volts.
Fortunately the cells do not ruin and just recharge them with a small battery charger and everything returns to normal operation.
Also the BMS (Made in Swizzerland) went dead on 2 batteries, but all cells are saved.

I repaired it with the new BMS16 purchased at Chargery.com
With a little interface that I built the BMS16 can control the HiperFets on the original Quantya power card.
This are some picture of my modifications.
Attachment 7293Attachment 7294Attachment 7295

My balancer is of the passive type and absorbs about 1A with a control on the voltage +-1mV.
Hope these info are useful to someone.
Greetings "

" I have torn apart about 60 of these packs for reusing som fresh cells. It is samsung icr18650-22p and the dates are different on each cell so I dont think its a rewrapped chinese crappy cell. But the weldings and soldering are very crappy and the bms is lowest quality. Inside the hoverboard all cables goes thru the moving part in the middle and cables are not protected.
It could be a great product but the chinese manufacturer did a bad job as always.
Hire a german or japanese qualitycheck and the problem is solved.

The Eltek will talk to anything that sends/receives the correct CAN messages. They use standard CAN frames, so in principle you should be able to program another device to work with them. The Orion has the messages preprogrammed in. If you go into CAN settings > edit CAN bus messages you can see the byte structure. Eltek uses IDs 2FF (receive data from BMS) and 305 (send to BMS).

I'm not sure about interfacing a Kelly and Orion. Again, the Orion uses standard CAN messages so in principle it should be possible. But HPEVS has custom code for communicating with the Orion, so you would need something along those lines.

The Curtis doesn't talk to the Eltek, only the Orion. Generally the BMS controls the charger not the motor controller. The controller should be off while charging. "

Hey Matt,

I always ran with HPEVS AC-XX and Curtis, so can't speak for other brands, sorry.

Currently discussing with HPEVS to upgrade my controller OS to their latest version so i can activate the BMS functions, should be doing that next week-end. "

" Decided to break down the Savage and move to a new frame I've had a crush on - the 1973 BMW R75. Got a Hurricane Katrina-flooded donor for $1, so it is go time.

We've got it working with the parts from the Savage:

Attachment 7290Attachment 7291

More build: full prototype, week 1, 2, 3.

Drivetrain:
Kelly controller - 250 amps now, would like more power, something that can talk to the Eltek/Orion
Orion BMS - nice unit but big, could shave the heat sink down, but would love something smaller, not sure I can do anything else if I stick with the Eltek
Eltek charger - a great unit, but I don't have it running at full 220 right now, would need to add cold plate for that. But I've got 220 at the house, so would like to keep, but open to a different charger/bms combo
Batteries - Loved the Leaf pack but gonna sell em. I'm sitting here looking at two Tesla modules with 888 18650's and cooling circuits, but no BMS hardware. Can't fit em in as is so I could: break the cells down and rebuild a pack. Sell em (got em cheap). Stretch frame and use as is. Thinking about a 3d printed or vac formed battery pack to mimic lines of original motor housing, but not sure.

Chassis:
Will drop front end, swapping for GSX or BMW rNineT front end. Hoping to vacuum form a transparent gas tank, rough component layout feels good for now.
Keeping the enertrac b/c I love the look of the shaft drive and the hub motor - mimics the original drum.

POP QUIZ: What's your dream build on this chassis? I'm ready to sell some of this off or move it to the Vespa. Fire away with ideas! And thx! "

" Hmmm... Check with HPEVS. All their software for the last 4 years works with Orion, as far as I know.

There's a way to turn BMS on with menu button programming instead of Curtis programmer. Read the instructions on their website.

Where did you get these ?
