Re: Interfacing Orion 2 with Thunderstruck EVCC [SOLVED]

There's no difference in the Orion Utility when using these special order units and a regular one.

The busbars of the 62kwh pack are the same size.

Re: Reattaching Cell Terminal - 62kwh module


You can check if it is nickel with a small magnet.

It looks like it's probably nickel plated copper, it's not magnetic. I was thinking it might be feasible to drill a series of divots in the part of the terminal that's pulled away from the cell stack to reduce the thickness in those areas, and ...

Re: Reattaching Cell Terminal - 62kwh module

does it seem feasible to you to try to manually charge up a single cell?

I don't feel confident telling you that this will work/is a good idea/won't damage your batteries. Your best option is to charge the whole pack with a BMS and let it take care of balancing the cells. However, I think you ...

Re: Interfacing Orion 2 with Thunderstruck EVCC [SOLVED]

There is a hardware difference between the BMS that I linked and a new Orion 2. They were special ordered from the factory from my understanding.

Re: 62kwh Leaf Pack max amps?

Any regrets?

Yes, that's one of the biggest things I would change if I did it all over again. The most I've seen my pack output is 600amps. I'm using Jon Volk's tune for the LDU so I haven't tuned the parameters according to my setup, but that 600amp mark seems to be right in line with my ...

After some very frustrating BMS issues, I discovered that the terminal of one of my cells had been pulled off of the cell stack.

Try to connect incandesent light bulb to chassis ground and HV minus.

That's a handy trick! Unfortunately (fortunately) the lightbulb did not light.

I have been using bare copper wire, but I doubt this ...

I am doing something quite similar. My setup uses a dual hall throttle and i would like to use CAN for transmitting the regen, by means of pedal travel. not sure which value to send on.


I’m not familiar with controlling the OI board over CAN, is that how you’re handling control of the OI board ...

I assume you've already read the threads about switching your A/B wires on the 4 pin encoder connector. I can't recall if that would affect the hand-turn test you're doing or not. Are your encoder wires shielded? I was bench testing with a brand new harness that did not have the cables shielded for ...

Re: Interfacing Orion 2 with Thunderstruck EVCC [SOLVED]

This is very helpful, I might run my setup like this. In this configuration, does the BMS just interrupt the loop when the pack is at full voltage since the EVCC isn’t receiving information through CAN?

Yes, one of the limited features of the BMS I’m using is that it only has one CAN bus. I can see the CAN data in the EVCC terminal but it labels the messages as “unknown.”
