Outlander rear motor and inverter

[rstevens81]

Looks like I might be investing in a long steel bar to do some experiments

item "a".

Hm... i am thinking of connecting to my other inverter and sensing unknown wires for transient signal when putting it in short. Of course i would be doing this with 48Vdc power supply...

In Volt inverter i see fault signal as a weak pullup with NMOS pulling it down when inverter is active. If something would happen control would release the pullup and stop the logic. A failsafe design.
If control is any similar the signal would look as a pullup to Va when powering up. Then when you start the PWM you should see that signal drop and if you provide any 3V to that line you should see a stop to PWM.
I think that would be best tested with OEM wiring intact, since inverter already requires 12V signal to operate. If you remove that signal you stop PWM completely.

@Romale: I put general info of Outlander inverter OI lobotomy to wiki. Feel free to input more data.

[Romale]

Hi. Yes, there is one significant edit. The HV signal must go through a divider of two 3.3 kOhm resistors. Otherwise, the level becomes too high after about 330 volts and the v3 board is not able to fully measure.
I soldered two resistors directly at the input of the measurement wire, through one signal itself, and the second from the entry point to the ground.

Ok i put the latest comment in there as well...

For me it was bad connection between inverter and motor ( Resolver)

I metered every pin on the inverter to check against the values listed in the service manual (see attached)

Note that RSDN should be pulled low.

Once that was sorted it all worked very easy, no particular sequence.

Hi , Just want to ask about your RSDN post, does it mean you apply +12V to RSDN if you want to shutdown? and cutoff/dont connect RSDN if yiu want to enable/start the motor? thanks

Belatedly noticed the earlier posts about nicked seals etc. If anyone needs spare parts I have two gearboxes that I need to get rid of. Available for collection in South Manchester.

Hello
I'm new (not to world)

I'm trying my hand at the inverter, first reading out CAN bus data as with the charger.
Unfortunately, it seems that this is not so easy, or the rear inverter is broken.
My approach so far:
Connected to the grey inverter socket as in ewiki.
GND, CAN H L, IGCT, and RSDN to GND.

Couldn't see any CAN data, which is disappointing at first, as it was so easy with the Outlander charger!
190mA current consumption at IGCT
Then connected the motor in the hope that it would come to life

I now have 350v at the inverter and 12v (1A power supply)
No CAN data

Now I have reconnected the grey inverter socket, but upside down.
Perhaps it was incorrectly shown in the wiki.
0 mA consumption.
No CAN data.

Grey inverter socket reconnected correctly, now 490 mA power consumption
I can't imagine that it's broken, but it was probably already broken before!

So my question is, what do I need to do to get data to the REAR inverter?
The second very important question is, is it possible to get CAN data just by connecting these 5 pins?

Try switching can low/high around there's some contradiction on the wiki when you look at both diagrams

Connect 12V power to IGCT and 0V to GND.
RSDN should NOT see 12V when in normal operation!
You should use a propper power supply, 5A at least. I suspect inverter can go into brownout if not enough power
When you connect to CAN H/L you need to terminate connection on at least one end if not on both ends. Transciever inside inverter is not terminated.

How my car is connected to inverter
1. I provide 12 ignition through the key to IGCT pin and 0V to GND
At this time VCU is online and in ready mode. This means it is actively sending 0x285 telegram at 30ms in drive mode
There is NO CAN from inverter at this time!
2. When i provide START pulse precharge relay raises voltage and then DC+ contactor goves HV. You should see active inverter CAN reports then
I use charger CAN signal to verify correct voltage just a precaution with precharge
3. When i put car in drive mode all inverter messages are flying on the CAN bus

To summarize;
1. You need to connect 12V to IGCT
2. You need to connect HV to inverter (by precharge)
3. Inverter CAN reports are active when HV is online.
4. Only then you can read and command inverter with your VCU
EDIT: I went out in the -10°C cold to demonstrate this via screen grab... it says -6 but i assure you it is lower than that ...
0x289 is one of the inverter CAN reports
0x285 is BMS heartbeat that all Mitsu components require for operation

I sugget you make all connections with your motor, resolver and HV first in your workshop as you would in the car. Then start the "car".

[OutlanderTry]

I swapped low and high, but I don't think it's related to high voltage.
I'll have to test it again. Everything from the inverter is dismantled, I can't find any faults, it looks like new.
I'll reconnect everything. Precharging is done by the inverter itself with its resistor anyway.

Hold on.
I swear on my life.
This morning, from 1 a.m. to 5 a.m.,
I tried everything, including a different power supply. I even removed my termination and added it back again.
It was as if something was against me. A wall of sabotage (matrix)?

Now after I answer messages here.
I replaced the power supply with the 2.5A 12V and immediately swapped the CAN bus
low with high and high with low

I did not connect any HV
I am not sending any data
BUT
I am now receiving data
What is going on here?
I'm also using more power than in the very first test.
Can anyone confirm that the device draws 450mA in standby mode and not 200mA?

What I did do to the two CAN transceivers, one is 8-pin and the other is 16-pin, was remove the paint with isopropanol and scratch around the pins and conductor tracks.

Did I accidentally fix it?

Then was anything wrong in the beginning , i had only 200mA

Hm... strange

I connect car saux battery with ignition so i provide inverter, OBC and heater with 12V so it is more than 1A.
But even if i provide 12V and 0x285 telegram i only get response from inverter is when i give it HV via precharge process.

To verify this i use ECAN USB interface

I love the new 2026 calendar

I already have my ESP32 VCU interface ready.
Dual CAN

5x ULN2003 outputs
5x digital inputs
2x analog inputs via the ADS1115 i2C interface

I only need to provide the code... i am only a ME so very slow in coding...

Search for the latest version 2.4 and 2.5
2.4 is meant for application with 2x CAN ports controling chademo fast charging or receiving BMS updates
2.5 is simpler, only single CAN but it can drive more PWM outputs

I put schematic on paper somewhere and i would have to redraw it. I will add schematic at a later time. For now let the pcb file guide you .
It was drawn with Designspark PCB.
There are also pinouts for VCU that i envisioned. You can certainly adapt them to your use...

If you want a single blank PCB board for testing i can quickly send you one...

It's not like I'm using can control. I install a johu version 3 board in these inverters. together with it on the table, when I first start up from the power supply at 12-13 volts, I see a current consumption of about 430 ma. The O.I. board itself consumes catastrophically little, so the consumption of the inverter in these areas is ok

[Romale]

O.I. management greatly expands the scope of available use. with it, I got 350 amperes of battery current with this small inverter, it seems to me that controlling the can bus will not give such a result. I also get a higher speed than in the Mitsubishi itself initially.

Yes i can draw max 200A from battery with OEM setup
On the RPM i am not exactly sure, but i can go up to 160km/h on that motor and that seems enough

Hello, thank you.
There's no rush; I don't plan on using the circuit board.
I'm learning and appreciate things like what you've shared. .

I've had the Outlander charger, inverter and motor since Christmas.
I programmed a web test platform for the charger; you don't need an EVse, it's simulated with pwm.
Today I created a test programme for the inverter.
I limited it to maximum torque input in the minus and plus range.
And I limited it in terms of runtime.
So on the HTERM console, you enter your torque up to 33 minus or plus, and at the same time to test the brakes, press Enter,
and it then runs for 4 seconds.
The setting can be changed in the code.
