No

I have:
Complete high and low voltage harness.
IOM
BCM
Fans

But why not change to Lipo, do you have NiMh batteries?

Just put a diode on the charger output. Maybe that is built in on your other charger. Yes I have thought about that but then the charger probably wont see that a battery is connected when starting to charge. Maybe connecting a diode with a 10K resistor in parallel so it can sense that battery volta...

Hello Joromy This project is awesome. Where can we find the teensy breakout board ? I would like to do a similar project with my car to Controller non CAN cluster. I have not any more left, could order 10 boards if you are interested. EUR 20 for one PCB only. I don't have enough orders to make them...

Is the Volk mods for tesla only, or can I use it on any acim?

I see your Charge Hysteresis is set to 200mV, and charge setpoint to 4200mV.
Then charging should not start, if cells are > 4000mV.
Could that be it?
Try setting Charge Hysteresis to 100mV

Interesting project will certainly follow this

I have wifi only in my main microcontroller, Teensy 4.0 with 4 CAN bus. Then I can control charger, inverter, BMS, heat/cool, instrument panel and more from one unit. This way I can have dedicated CAN bus for the inverter and BMS, and no trouble with different speed and CAN bus traffic. Would be nic...

Maybe a gauge?
Maybe join the two left boxes, and add motor temp and other essential info?

This looks great!!
One thing that is annoying with old interface are the "name value unit min max default" is scrolled away.
Would be nice if it was static, but you may already be ahead with that?

Inputs have max rating of 3,6V, some of the inputs are 5V tolerant, but I always put a 10k in series to be sure.
This pdf may help to understand the different methods of input/output circuitry.

Thanks for the help :) I gather that it’s the inrush of current which can damage the Capacitors, by extending the time I think I also lower the current? Therefore extend the lifetime or mitigate the risk to the capacitors. The main reason for precharge is to save the main contactor, and the resisto...

If you use same as Tesla does, it should be properly? I my model S pack it was 23ohm.
Have used 50ohm myself (50W)

We got two gen 2 chargers and opened them today. Turns out one of them was WET on the inside. Not water from the cooling outlets, definitely from within the unit. If it came from a wrecked car, it could very well be rainwater, or removed and then get wet. It's not very whether proof even when lying...

I am a COMPLETE novice to what is required and would have just bought the kit with the wifi module programmed had I realized it needed it 2. Anyone willing to program one for me (for a fee of course!)? You don't need to buy it together with a kit, Johannes are selling them programmed and ready, for...

As Bart just found out, JLCPCB have removed the STM32F103RBT6 from their library. Like completely, it's not even an extended part. For those who don't know, that is the main processor that has been used for openinverter for the last 10 years. Also it seems the price has exploded to around $12. I ha...

Just got this STM32G431 dev board for BLDC/PMSM. It has CAN, FOC, current sensing, encoder and even a ST-link debugger/programmer. But what can I use it for, can I beef it up to drive a IGBT. Looks very capable, will be fun to play with. Price $19.15 https://www.digikey.com/en/products/detail/stmicr...

I use cab500 works great, without any changes

Lots of Eltek 3kw chargers, have used some of them, they are CAN bus operated.
100-250VAC input 250-420VDC output.
Now they are really cheap!

Hi, and welcome. Very cool project!!
The tesla board is made specifically for tesla motor.

The ver3 board is more allround board.
https://openinverter.org/shop/index.php ... duct_id=58

What kind of motor is it?

Would be nice with some tech spec.

This is great, will try it out!

Ideally, what should the sequence of precharge and contactors closing be for the truck upon start up? The basics behind contactor and startup sequence. Drive: 1. Negative contactor close. (By BMS) 2. Precharge relay for TIM close, and charge up the capacitors. 3. Inverter will close Positive contac...

Based on the clues provided above can you think of reasons for my malfunctions? Sorry for all the questions.
Thanks.

I'm sorry, i missed this one.
How is it going, have you solved the issues?

Heh... i just got a crazy idea... You could take the REX and inverter unit and put it in a house/basement. Then you would take coolant hoses and loop them in a water container for some 800L. You could wire the inverter output to some solar inverter and make electricity and hot water. Additionaly yo...
