Id like to start a thread for orion bms users and for future users.

State the setup and share some settings and ideas to help myself and others improve the setup and SoC reading.
Some canbus settings and tips and tricks for relay setting to have an external battery heater etc.

My setup is:
Orion bms 2

Battery: 3 modules renault zoe gen 1.
3 modules in serie of total 100V
estimated around 70Ah . 2.8V-4.3V

If anyone have a good setup for Kia soul cell or others that are not included in orion setup please share.

I was trying to configure the SoC reading but charging the pack from a low voltage , 2.8 to 4.3, to max voltage with 1/3 C rate. 20A in my case. Continuing reading voltage value and Ah to try plot the charge curve.

One problem I noticed is that if you already have drift points set in orion the Ah meeter will adjust, drift, to accumulated Ah value and therefore adjust the SoC value on the fly. So theres no Ah meeter in background calculating the total Ah you charge with. So top tip to do this in the beginning is to have no SoC drift points when trying to plot the first charge and discharge curves.

The shunt capacity is pretty good for balancing. They state up to 200mA. I had a module out of balance before starting and had to leave it balancing for more then 20h for reaching withing 0.05V with the rest of the pack.

ill share some pics

I don't have anything to share yet, but I will be using an Orion2 with my electric racing kart. It will be monitoring a 42S10P 18650 pack combined with a Kelly KLS14401-8080IPS controller.

How do you like the BMS? For me it's oddly the least expensive one available, is supposed to have great support, and will easily support canbus controlled charging.

Nice setup you building, what are you expecting for power output and performance from the kart?

I can confirm the support is superb with fast answer and they understand easy what you are building or problems. For example they havnt got a plug and play for battery heating but they have a work around to control relay for a heater.

will be interesting to see in the future what they will add.

The first battery I'm building will have a usable capacity of 3.4 kWh. I'm expecting a possible peak power output of 55 kW (full beans with a fully charged battery for a very short time - for example, a drag race).

For a sprint race with B&S 206 karts, which is what I will be starting out with, it should be peaking at around 6 kW with an average of 4.2 kW over a lap, for up to 45 minutes per charge.

For a sprint race with 100cc karts it should be peaking at around 13.6 kW with an average of 9.5 kW over a lap, for up to 20 minutes per charge.

Hello @18650
Very good to see that you got the Orion BMS to work with Renault Zoe modules. I was looking into a similar setup with 8 Gen 1 or Gen 2 modules in series and would be interested to hear about your experience with your build. Would you be able to share some more information with me?
Thanks & best regards,
Remi.

I love this idea, and look forward to learning from this thread, if there is a version that supports the BMW 530e PHEV HV battery pack I would be happy to jump on board

Hi all,

I am setting up a battery system with very similar LG Chem/Renault cells as the original poster of this thread with a Orion2 BMS.
The in-depth description of the original battery can be found here:

Renault Master/Kangoo/Zoe 36kWh Battery

Out of the 12 modules (3 kWh per module, made of 8 cells), I am using 8 modules (24 kWh) in a Renault Twingo. I have now set up the Orion2 BMS (visible in the picture on the bottom left side.

Bicycle tire Tire Automotive tire Motor vehicle Wheel

As it is my first time working with the Orion, I would be grateful if some knowledgeable people could have a quick look at the setting and confirm if everything is OK.

My first question is this screen here (initial setup). Do I need to fill in something in the selected battery cell (Profile Wizard) section at all? The problem is: This opens a drop-down with different pre-configured batteries, but no LG Chem or Renault pouch cells are available there. I have selected the Nissan option in this screen for the simple reason that it is probably the closest to my own cells, but of course not the same at all.

I am working with 8 modules in series with 8 cells each, so 64 cells. This is a live view at the single cells. In my eyes, the cells seem to identified OK. Anything dodgy to be seen here? Does the pack SOC make sense?

Here's the parameters screen:

...and here's some more parameters:

I would be very grateful if some expert could have a look into it. If somebody would be willing to offer (paid) assistance through TeamViewer to double check I would be a taker.

For readers in the States who are not familiar with the model: The battery resides in this Renault Twingo, a lovely French A-segment (subcompact) car with a microvan design first presented in 1992.

This car here was a test vehicle for the molten-salt (ZEBRA) battery in the 2000's and has recently been upgraded to a LG Chem Li-Ion battery system as described above.

Appreciate any comments or help on the Orion2 Setup (or of course other questions about the car, too).

Best regards,
Remi.

@R4eCV
Did you find which cell settings to use for the LG chems? I just got to the first bootup of the orion 2 with a full Chevy Volt pack. I have most of the cut off voltages figured out but I can't find any data on temperature derating.

First EV, never mind the wiring spaghetti, it is how I got the vehicle back from the shop that I took it to have the 12 lead batteries replaced with 5 Tesla Model S battery modules. The fancy dash display they sold me, is inop, tech states that I have to cycle the batteries a few more times to have it register correctly.

Anywho, I have a Orion BMS 2, and waiting for their Wi-Fi module to come back in stack Togo with my original plan if monitoring the pack status via iPad Air. Anyone have photos from the Orion Wi-Fi output and real time comments about how it works?
