makes sense, i put the inverter back on CAN1, dcdc and shunt on CAN2 and still getting timeout. ill play with the inverter can setting tomorrow ... I have a similar problem with Teensy VCU and my Outlander setup. I use everything from Outlander in Mazda MX-3 car; Inverter, motor, charger and heater...

I see a pattern :o Also ordered same charger from UK ebay seller. This is how mine arrived.

It seems like this stuff is quite resillient and packaging is there just b...

...I must admit I just spent half an hour starring at that thread and spinning my charger around 960° back and forth only to realize you do not show a pic of the "high voltage port gland" for the charger... For ease of use i cut my chargers DC cables and put MC4 connectors on them. This v...

I used PWM code for speedo dial and it responded with dial jumping...
Then i put the speedo function after the inverter RPM report function. This is what i get:
Seems like it would want to keep the beat with radio .

I need to apply some filtering other than in code really as much of it is of no interest and maintaining 10 msec update on the 285 is a challenge with the dash update True. I am slowly leaning towards using a separate BMS with 2 CAN bus lines. One would drive JK BMS modules at 250kbaud and the othe...

Ah!!! Nice idea. Will test this today thanks.

Any opinions or knowledge?

Motor is rather small, maybe 28kW?

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 enoug...

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_...

Am I understanding this thread correct you are able to command 280Nm from the stock inverter? I assume that means that you are exceeding the stock 60kw power output? Or is it just hitting 60kw at lower rpm? (I assume current is recorded from the shunt?) Not yet. I reset it back to 230Nm. I managed ...

You need to check the response message from BMS void canRX_001(const CAN_message_t &msg) { Serial.println(msg.id); Hm... i still have to verify this. In the meantime i noticed my speedo function is misbehaving. The needle is oscillating a lot. I use Tone function for this as it can quickly vary...

Are certain BMSs not included in the array, or is data from one BMS partially missing? 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 module...

I got it now thanks! Reverse is now good even in uphill. Next i tackled the missing CAN traffic on CAN1 that i setup for JK BMS comms. I found out there was really bad 3V3 connection and i resoldered this link. Now i get good traffic. Because i didnt want to connect BMS requests to shady timers i op...

My math suggests that 35kw cont, 85kw peak should be sufficient for a 2t vehicle with performance characteristics of a microbus from 1989 - that is, slow, but able to keep going at 100km/h continuously. Well i can say i could get 11s to 100km/h for 1.2T car. I can see max 230A with 320Vdc battery =...

Change the -6 for more torque So do i go less than -6? Ok like if the higher number makes more torque? ...

All three can bus work fine for me. One balancer did not respond well to requests, I replaced it. Tnx i will look into why i cant get any traffic on the lines... On the other hand i see very little torque in reverse. Today i tested this driving in a small hill. It was embarrasing :(. How to up this...

Now finally everything works as it should with VCU. I got good acceleration, good regen response, Nice reverse drive and everything connected to Outlander components is operating aas it should. Acceleration at 13s now. I managed 11s with large torque swings, but it was not comfortable. I setup all a...

Ok so I think we can say your application does not need any ramping to control wheelspin. I would suggested removing it and simplifying the code, your fork is quite far from mine now so It's hard to debug any issues you are having I would be interested to see if you can actually command (and get) m...

I recommend to you that during troubleshooting you wire your DC contactor through latching circuit.

Did you also change or comment out the over torque check in the code? No i kept it in as i thought final sanity check might help :). I just prepared a new map for test const int pedal_map_three[21][22] = { // Sport // map 3.. /*250*/ {0, 0, 18, 20, 20, 20, 18, 18, 18, 16, 16, 16, 16, 16, 16, 16, 16...

I measured acceleration at 15s from 0 to 100km/h....
I made some effort to play with map3 and changed some values at the first section up to 2500rpm from 7 to 15! This notably increased responsiveness from takeoff. At second try i got 14.4s to 100km/h. I am sure i could do even better....

My iteration of program works without BMS at this time. You can get it here:
