i am trying to built my circuit now....
if i understand correctly your process works like this...
1. you press "brake" to power VCU temporarily
2. you press Start button connected to enable pin
3. VCU commands one relay to latch 12v power to supply itself
4. VCU goes to ready state (or would it be ...

I think this variation will work. But you still need to swap the current and resolver sensors for correct operation. And most importantly, the gearbox is not designed for operation in the opposite direction. The pump pumps only in one direction, and the gears have teeth tilted in the other direction.

When I press the brake, power is supplied to the VCU, and if I press the "Start" button while the brake is pressed, the relay to support the 12V power supply is turned on and the VCU goes into "READY" mode. If I press the "Start" button when the engine is not rotating, the VCU turns off the power ...

Bad news is the 3.x ones are still a way off by the looks of things, which makes the BMS side of things tricky.

teensy 4.0 is a full replacement for teensy 3.6. The pin layout is completely the same, only the processor is more powerful

Thanks for the prompt updates!

It looks like the sales rep I was speaking to didn't really know what they were talking about, so the inbuilt CAN is isolated. Does anyone have the datasheet?

I've ordered a few of these units, different vendor (directly off JK taobao store, JK B2A24S) and would ...

I've been looking around for BMS options and have landed on this project. I'm trying to prioritize cost and this seems most effective.

Have been in contact with JK-bms sales reps to try to aks more details out of them. Basically the same info that we already have.
From what ive told, the CAN ...

I managed to get 8.7s at one time but i cant repeat this anymore. I dont know what i did.
Did you notice the slow start almost like a rubber band? I guess this takes at least 0.5s from you....

Also i must reseal all the moving parts of chassis. There is so much chatter in the undercarriage my ...

Thank you, the tests were successful. I was especially pleased with the sport mode. Acceleration from 100 km/h in 9.6 seconds.

No, I meant throttle maps

Done that :)

Same thing, only 3 ...

Now I am finishing the installation of 3 Outlander chargers for stationary charging of 10 kW in the garage from a 3-phase power supply. And one device is mounted on the car.

Well...

I managed to see what signal EVSE shows to Cp line. And to my surprise it was 56% PWM not 26% as i imagined.
This forced me to add additional variable PWM_sig so that i set limits to my current calculation.
First i read PWM_signal from byte3. Then i check if signal is less than 6% or ...

Nice unit.
Can it blow air out of the case? How do you make sure no water gets in?

I plan to route the air ducts under the hood or into the trunk

the seam is not heated up enough, there is no need to rush.

2. Other relay will show active signal on pin_8 and activate charging process.
This one is tricky as it will also power hydro pump of the power steering. A bit annoying to hear this with charging...
I will have to think about how to use a single relay to sense PP and command charging and second ...

I have such a fan installed inside the battery case.

OK now i changed from tone to PWM code and it works...sort of :?.

I still get needle to jump by 10km/h. This lets me to belive the problem is not in the code but rather in the CAN bus rutine or chip.
It seems like inverter report does not arrive to VCU in time and so speedo is not updated fast ...

Request BMS

The tone function has another parameter: pulse duration.
tone(pin, frequency, duration)
And also in your code, line 2026 "tone(OUT9, 3000); " what is it for?
You need to enable hardware PWM. The code already contains the library #include "Teensy_PWM.h"

frequency = 10000.0f;

PWM_Instance = new ...

I have 84S cells as well. But i use 7 BMS modules. Each BMS module is connected to 12S battery module as this was the easiest. When i connect to CAN lines i can see the FF request going out and i see all 7 modules reporting on the line. Everything is good on the lines but VCU does not read the ...

Are certain BMSs not included in the array, or is data from one BMS partially missing?
I only use data from cells that are not repeated in the array.
I have an 84 cell battery, 4 pieces of BMS.
