Zombieverter + Thunderstruck MCU

[CapriV]

I have the zombieverter running my 450h and the battery box contactors.
I have the MCU from Thunderstruck that runs the BMS
Anyone using these two systems combined?
Thanks

Do you have a CAN spec for the Thunderstruck MCU?

What functions do you want to have the Zombie do and which the Thunderstruck BMS?

I have the mcu but no Zombie. The manual has pretty decently documented functions and can mappings. It also has a list of OBDii SIDs, and recently Kelan from Thunderstruck sent me a DBC for all the J1939 messages it can handle. If you just want it to pass along SOC, voltage, amps and temps you should be able to do that pretty easily with the j1939 table.

Hey.
I want the Zombie to control the 450H with access to the IVT-S can
Then the Thunderstruck MCU to handle the battery charging and management.
I have both setups working separately on the bench.

Kelan said both systems should be able to use the same IVT, I do have 2 of these though.... maybe use one for each?

One thing I have not wrapped my ignorance around yet is how to combine contactor engagement for charging when the zombie is powered down.
I have the Zombie working the negative, positive & precharge contactors using a bench top power supply and the motor is spinning.
I will have 2 separate battery boxes in my car that will be wired in series but how do I get the zombie to close all the contactors (and precharge) for charging via the TS MCU. Or do I wire in a complete second set of contactors for the TS MCU charge circuit only?

I would also need some sort of proximity fail safe wired to the zombie to halt driving when charging.

I'm just getting back to this project from last year so forgive me if this is a dumbo question. . . Thanks

Zombie configures the IVT different then default so you will need 2.

Power on the zombie, utilize a 12V input signal to set it to charge mode - possibly need the charge interface set to Chamdemo (or other but can easily be made to work (worst case I code it in)).

As for drive away protection, once in charge mode you cannot go into drive unless you key off the zombie it needs to go through off before allowing drive.

Sharing the Voltage and Current limits can also be done if you have info on the MCU CAN messages.

Ok. thanks for the input!

I guess when enabling charge mode it will activate the precharge circuitry?

In does the contactor sequence for charging yes.

If you're using the Thunderstruck charger, it has a 12v output that's active during charging. That's how I wake my vcu. Can also be used as a drive inh although it won't be active if charging is finished but the plug is still in.

There's also a NC relay in the charger that opens during charging in case it's helpful to interrupt a signal somewhere.

Yes I'm using their TSM2500 Charger (CAN enabled)

Thanks for the help on this, very much appreciated!
