I mentioned a while ago I was having problems with the car cutting out as I drove. I have to admit it was getting me down as I didn't really know where to look but as sometimes happens fate lent me a hand. The last couple of times I tried to charge the HV battery it stopped charging after around 30 ...

I hope so, I just ordered one.

Does anyone know if the 7807A021 will operate the same?
It is going for a good price here

Once I got the cable issues sorted I concentrated on getting the timing right for turning on the inverter. For a while I struggled to get it to work reliably if turned off and on again but I think I've resolved this by using Output3 from the VCU to power the Inverter. When I get it documented I'll ...

First i would advise you to make a latching relay circuit. The fact you are using timed relay to power your contactor can be tricky. I allways want to have ability to latch contactor so that no mattery what VCU does HV wont be an issue. You can do this by using two automotive SP relays (or single m...

The board uses an NCV8401, designed for the job, 12V goes to one side of the contactor coil and the other to the VCU. Thanks Jamie, this is good to know, the issue I had with driving the contactors was very early in the evolution of my LV connection box so it is very possible I had wires crossed so...

You could try running contactor from negative side. Supply 12V directly from ignition and use timer relay to bring GND to contactor. Maybe GND is more stable... That's a great suggestion, however I'm using the neg output from the VCU to power the timer relay. I tried connecting the VCU directly to ...

I was about to say "It looks like the issue is a faulty contactor." I put a meter across the 12V supply for the positive contactor and when I turn on the headlights the contactor opens and stays open even though the 12V to it doesn't change." However it wasn't quite as simple as this....

Your 0x285 message looks funky as too, but it seems to work. Wiki suggests the 3rd byte should be 0xB6 to pull the EVSE into the correct state. Yours is 0xAA. Not sure if this is a full log, but some public EVSEs wont work if you skips state B and jump straight to C. The Pod Points at Tesco for exa...

Yes, agree 100% with you guys, thanks for showing what is happening.

I have ordered a couple of 12V fuse blocks to try and tidy up my wiring.

In the meantime I'll try to figure out what is happening.

The plot thickens! :o First I want to thank you guys for your help and support with this but I think the charger is OK and not the problem. Today I started a charge and a CAN Dump with SavvyCan, around 20 minutes later I climbed into the car and tried something which caused the car to cut out a coup...

The BMS now controls mine, just pinging out the relevant canbus messages when it's all plugged in. Is yours overheating maybe? Outlander heater too. Had a horrible thought when I spotted the snow: when I put some fluids in to test the loop, months ago, did I put in anti-freeze or just water? Can't ...

Is it possible that EVSE somehow disconnected PP signal? That would cause the change you speak of. Or maybe overheating.... There is B5 = Statusbyte within 0x389 which can tell you the status for charger and there is one for DCDC in 0x377 B7 = Statusbyte At the moment I can't rule anything out espe...

Hm... what mechanism do you think is there to disturb the inverter? Disturbances usually happen because faulty 0x285 heartbeat. It happend to me recently and i solved it by clearly determining timer for heartbeat. What kind of control do you use with charge? You have a voltage control loop in place...

Thanks, that very helpful.

Its strange but charger works with 100ms and inverter works with 100ms, but heater seem to work with less than 30ms. I seem to remember AC compressor needs 30ms as well. Due to easier application i simply setup a single timer for one 0x285 telegram at 10ms. I'm using your Due sketch to control my c...

Minor update: finally got around to instituting proper charging with the Spaceballs/Simp BMS. - Plug in charge cable - @JamieJones' PP detect circuit turns on main power and signals BMS to go into charge mode - BMS sends start signal to inverter (12v high - my OI/EVBMW board in there still refusing...

The data being sent on 0x285 does not look correct, A4 40 AA 00 DF C0 xx xx I thought it should be 00 00 B6 00 00 00 00 00 for charging. From the log it looks like the charge may have terminated at 375V. Hard to tell exactly as only 1V resolution. Do you mind if I ask how to extract the voltage fro...

The software supplied with this tool doesn't allow opening files so I'll have a go at capturing using Savvycan.

Been a while since I touched it.

What was that logged with? doesn't open with savvycan I bought a CanAlyst-2 a couple of years ago and as it was installed on my laptop I used it. I read the file using LibreCalc and used auto filter to focus on certain frame ID. This is it on Ebay https://ebay.us/Fa7Ean Hm... can you elaborate on t...

Here is the full log from around 20 minutes before it failed.

This is the CAN dump from the charger/Due It was over 29Mb so I removed the frame ID's that did not change the entire time listed below and reduced the time frame 0285, 0286, 0563, 0568, 0569, 0663, 0664 038A was climbing up until 12:55:49 then starts to fall. Another odd thing I noticed after the c...

No need to worry about it, i noticed the same. Symptoms; It seems that when charger is allways connected to HVDC and pin8 is connected to 12V power supply for a longer time charger sometimes goes out. Also i noticed that when i keep charger connected to 12V and remove the EVSE plug sometimes charge...

Hi guys I'm getting some odd behaviour from my Outlander charger and wondered if anyone else has seen the same issue. I got the car on the road a couple of months ago and have done around 600 miles so have charged it maybe 30 or 40 times give or take. Initially it charged without any issues every ti...

So today I had my 2nd inspection by the DVLA MOT inspectors so now I have to wait for the decision coming from Swansea. It seemed like half the MOT inspectors in Belfast were looking at the car as it attracted a lot of attention and the senior inspector came over to me and complimented me on the job...
