Found: $470 second hand 108 Cell Orion 2 BMSes, limited functionality

[Scrappyjoe]

My fellow hackers, I found this listing on the internet. I am not affiliated with the company - YMMV.

https://www.greentecauto.com/hybrid-bat ... /o2bms108z

Here are some copy pastes from the listing:

Orion BMS for 108 cells. Comes with the following items:

2 contactors
1 bypass contactor
1 bypass resistor
1 fuse with fuse holder
1 current sensor
Low Voltage Harness
Cell Tap Harness
Temperature sensor harness w/o sensors

We have over 100 of these BMS's. You will receive the following items.

Item Brand Model Number
BMS Orion BMS 2 O2BMS108Z
Contactor X 2 Gigavac GV251BPB
Bypass Contactor Gigavac P195BDA
Bypass Resistor Vishay LPS300H 100R
Current Sensor LEM DHAB S/124
Fuse Ferraz Shawmut A30QS250-4

These components were removed in a custom battery build that was never used. This Orion BMS is currently programmed to LTO cells. We've confirmed that you are able to download, change, and upload the program. You could also upload your own program into it.

Confirmed present functions:

BMS Balances
Communicates by Can Bus 1
Confirmed missing functions:
No relay control, the relays were activated from outside the car
No Multipurpose functions
CAN Bus 2 is not functional
No Isolation detection circuit
No safety enable low side driver, will not work with CHAdeMO charging

I found the listing because I am looking for a BMS that works with Eltek chargers. If anyone technically proficient cares to answer - do you think the above will work with https://openinverter.org/wiki/Foccci#In ... ur_car/BMS foccci? I am planning Eltek for AC and foccci for CCS. The comment "No safety enable low side driver, will not work with CHAdeMO charging" worries me. I'll be using a ZombieVerter VCU if that matters.

I've not used an Orion, so take this with large grains of salt:

It sounds like there is either a custom software or custom set of parameters being used, and the seller thinks these can be reconfigured. If so, it might be possible to turn CHAdeMO back on. To use with FOCCCI it would be very helpful/necessary to have CHAdeMO working. I would reach out to the seller and/or Orion to get clarification on resetting outputs/parameters. If it can be reset to a "standard" Orion2 configuration, that's a heck of a deal!
