The ZombieVerter VCU Project

[EV_Builder]

Ok i found the CalcSOC method its in the utils..

[Jack Bauer]

That's it. Simple in theory as the isa shunt provides kwh used but I'm too stupid to make it work.

[Jack Bauer]

Ok I'm going to break this out into a separate support thread to try and keep things in some semblence of organisation.

[EV_Builder]

Good idea. Check the LIM CCS thread also maybe move some of that as well.
Software development deserves a own section IMHO in that way it's not mixed-up with support.

okey updated the GUI with some new features

Time to test my c++ class on the VCU board...

Making and using lookup tables never was easier

I like your table generator! But isn't it more a BMS task to protect the battery and tell the VCU max charge and discharge currents?

Attached some inspiration from lithium balance s-bms...
They use separate temperature and SOC dependant lookup tables for charge, discharge and regen.
No 3D table but separate 2D tables for temperature and SOC and then they use the lowest value as limit.

Yes! very fair point! So the place where we add the code will decide 'who' is reporting it. In the VCU it could still be the BMS class if there is one in use.

Multiple tables can be added indeed. Just copy the file and edit.
For a temperature correction value. If needed I could add it to my generator but I think waste of time for now.

I first need to get my GIGADevice running in CUBEIDE someone accomplished that?

[Jack Bauer]

So given I have had almost no feedback from the beta release that must mean it's perfect. The boards will be going on general sale this weekend.

Hi. Have you done the motor temp sensor and brake light inputs on the release board?

[Jack Bauer]

Yes

also NCV8402 now NCV8440 which is pin and parameter compatible

[chuuux]

Yes

also NCV8402 now NCV8440 which is pin and parameter compatible

Great. Can you give some instructions, please, for DIY modify V1 beta boards about temp and brake inputs?

[Jack Bauer]

No sorry I'm up to my ears in work and life right now. We have more then enough people with the requisite skills on the forum here now to help out in this way.

What was wrong with NCV8402? Just replaced them.
I have now swapped the LQFP100 for a 'real' STM..
The Giga didn't want to debug on my IDE...
Actually not sure if this was a good idea but hey..it's journey..

Ok. I've found and soldered it.

[Jack Bauer]

Much appreciated! Now we just need a wiki page:)

Re beta boards: Ugh, yeah, haven't tested my beta board cause I haven't been able to find the missing part of our prius harness so far. Sorry about that. Suppose today is a good day to try the junkyard.

Re wiki page: This one? https://openinverter.org/wiki/ZombieVerter_VCU

[Jack Bauer]

ah that's great thanks.

Now on general sale :

General SOC calculation and charge remaining timers for CCS now added to the ACDC_Lim branch.

Slightly off topic, but could I use a LIM with my Leaf VCU?
I know it needs some rework to run, but why not?

Yes, as long as someone adds the code to communicate with the LIM. But better first wait for the LIM protocol and CCS process to be finalized.

Great! Thanks for fast reply.

Is it a plug you are looking for? Show us the one you need or its mate with a photo and maybe we can ID it.

Yes, the main inverter plug for a gen 3 prius. Somehow I have everything but that.

[chuuux]

I guess you need G926047010 and G926647010 connectors. They join to each other.

[Electro Wrks]

PNs confirmed. A Google search shows they are available as repair parts from US Toyota stocks. I've forgotten where the pins(2 sizes) are available. You could salvage them with a length of lead from other harnesses. Also, salvaged pins and leads have the nice little sealing rings on them. The tool for unlocking the pins can be made from a squared-off(by careful grinding) regular or extra long push pin. The unlock holes are the small rectangular ones next to the larger pin holes.

Before the tool is used to unlock individual pins, the white plastic primary lock in the body of the connector needs to be slid sideways, with a small screwdriver, to unlock and lock all of the pins in the connector.
Shouldn't this info be on a Wiki somewhere?
