It works on the latest 5.38 firmware with the inverter in run mode (not manual run!)


I found out the reason why my idle mode wasn't working! I hope this information will be useful to someone in the future.
I had the values of pot2min and pot2max set to 0. Even though I had the offthrotregen ...

how do I get to this merged branch?
and thank you for your build, I will definitely test it.

This is very sad news. 99% of the community will not be able to collect firmware files on their own.

7.2seconds 0-100 km/h on grass!!

this car uses a firmware version with a modified syncadv principle (5.36.42B-foc), and the battery voltage is 260 volts. two Outlander motors.

It would be interesting to test the updated firmware on it.

Is it possible to become a beta tester?



I didn't notice any significant differences in our settings, but this mode doesn't work for me.
You have cruise support enabled, but I have it disabled. Could there be a problem in this area?

This is great, but I haven't seen this firmware version in the releases. Where can I find it?

Moved to Drive trains. Please check for a better category before posting under "General".
A classical task for the new maintainers to take care of!




I thought that the question about the program code corresponded to the "general" section in "inverters" . Please forgive me if I was wrong.

This mode was meant

Hello everyone.
I remember very clearly that I used this mode on one of the previous firmware versions, and it always kept the engine running at idle for automatic transmission.

However, today I was unable to start it. I tried pressing the "start inverter" button while holding down the brake ...

Yes I am considering if it is ok to just add Lebowski brain directly to inverter or would the main chip protest in some way. You have to remember current flow and desat sensing is still active when power supply is on...


I did not take any action against the native processor, it remained in its ...

if you add two more fans on the other side of the radiator, but on the "other" side, so that the air flows together, your problem will be solved.

this temperature is quite normal, there is no need to worry.
for the inverter, anything above 80° is critical, and the motor can tolerate 130° in long climbs.

a) cracked solder joint of connector on OI board. Diagnose with microscope or by wiggling every single pin with tweezers. (I don't think a continuity test will discover this because intermittent).

my opinion is exactly the same. somewhere the soldering contact on the control board is missing.

I've always been curious about how to get the basic RPM of the engine from the power plant using sinusoidal firmware.
For synchronous motors, it's easy to do this by disabling the FW, which allows you to obtain the RPM based on the current battery voltage.
However, how can усwe achieve this using ...

Thanks, I didn't think of that. It's a strange solution, but you could use 12 volts for this purpose, like everyone else.
I'm going to use it with a small V3 Joohu board and not use the small steering inverter.

Hello everyone. I need help with this inverter.
I'm applying 5 volts to the red and black wires, but the drivers don't receive power, and connecting the inputs to ground doesn't open the channels.
What am I missing to get it working?

and why not use a charging system using an OI board??
in boost mode, you can supply any constant voltage to the input, even 75 volts, and an inverter with a motor will raise it to your battery level.

@Romale did you ever figure out the issue?

......

How should I interpret this? Did I mess up soldering one of the JSTs, or is there a bad component on the board? Should I be concerned or ignore the error?


Hi. I'm not sure what to say to that.
No, I haven't figured out the problem.
I have ...

This can be used on the DcSw positive contactor output. So only when you have other means to control the latter


it could be a great feature if it used a less sought-after output (for example, instead of "out vtg" or "out err")

I tested charging with a boost current of 100 amps, it works great ...

I noticed the appearance of a new feature (80, 81). do I understand correctly that this can control the cooling fan!? if so, at which exit will it be +12 or gnd?

once I get together, I'll create a theme for this car. everything will be there))
here I just showed how the syncadv improvements work for this firmware

I give my report: with the corrected firmware, when I abruptly released the pedal, I received a powerful braking force that led to an overcurrent. by increasing the vlimmargin parameter to 4900 and lowering the syncadv to 3, this problem has gone away. However, it should be noted that I drove ...

in general, the minus of cell 55 should be the plus of cell 54. why did you decide on 56??

So any recommendations from anyone for a charger that won’t break the bank? Dont anticipate doing this often, so feature rich is not necessary.


You can use any old charger from a mobile phone with an output of 5 volts and 2 amperes and watch the voltmeter to perfectly tighten the 55 cell.
You ...

They work with low voltage just with lower efficiency than low voltage mosfet inverters


this efficiency is so SLIGHTLY lower that the huge gain from the price outweighs the huge advantage in the direction of cheap inverters from Outlander, Honda or note-e power.
The very inexpensive rear ...
