Is the BMU VIN coded? Or could you buy a late model BMU and "upgrade" in a plug and play fashion? Having to have the module coded would make it harder but even still it might be an option once warranties run out to get a boost in (or at least restore) electric range.
I'd guess either way mitsubishi would have to do a reset /recalibration of the pack but it would be interesting to try

Interesting difference between the dedicated EV company (Tesla) where seemingly everything can be upgraded over the airwaves and the dinosaur vehicle tech company where "no, you have to buy the new model to fix that problem" :-(

I don't know the answer to that, but I do know they cost around $5K as the dealer we had the vehicle with after that particular event resisted getting the part in for weeks. I said to them in the beginning that I believed the problem seemed to be in the BMU (after discussing with him the fault codes they were seeing) and their reply was that the only way they could check that would be to get in a new BMU and try swapping them over. But if they were wrong, they'd have to wear the cost of the part. Eventually they relented, got the part in and bingo the problem went.

The interesting sequel to that story is that a year later after our battery problem, we suspect that the original issues were likely also due to moisture inside the battery compartment messing with the cell-top modules. But that's speculation now!

Just bought one it is a 2017 and at full charge it reads 33km range available. Not happy but unsure what to do to be honest.

Where are you? Perhaps there is someone nearby that can check battery capacity using OBD2. If down you may have a valid claim against Mitsubishi - it's been successful before.

NZ Northland. Would I contact Mitsubishi directly or go to a local dealer?

I was actually thinking of an AEVA member but a dealer would do it for you - at a price maybe. Not all dealerships handle the PHEV.

How much have you driven it yourself? Be aware that the range it guesstimates is dependent on how you have driven over the past few journeys. If you've not driven it much, but the previous driver was a leadfoot, you'll find the range will improve if you do a few trips to discharge/recharge the battery. Also, using the climate control will reduce range. Using the "eco" mode button should help improve range.

The quickest and easiest if you don't have the OBD gadget is to set the charge cost to 1 in the system and then charge it from empty. If the charging cost is around 9 you have a pretty good battery. You could also use one of those power sockets that measures consumption. In my experience they read almost the same as the built in MMCS.

The range available display is not useful for assessing the battery condition... except if it shows more than 50km every time after a charge :lol:

Hi all. Sorry to bump the thread. I am looking at purchasing a new 2020 PHEV.

Is there any new information on the battery issue that I should factor into my buying decision?

Do folks feel that Mitsubishi is close to acknowledging the issue and providing some sort of fix or resolution?

Cheers.

I have read on a Facebook PHEV group that the MY19/20 has a "BMU bug" and there is a fix being rolled out for it.
In general, passively cooled batteries like the PHEV are never going to last as long as actively cooled batteries like Tesla's. However you are not paying the same money either. Nor is battery degradation such an issue in a PHEV as the car still drives as a fantastic hybrid whether you have 50km EV range or 5km. If you want an EV around $50k, buy something like the MG ZS EV which is a small SUV. However if you want to travel, the PHEV allows unlimited distance with only 5 minute stops. Sadly right now, EVs still require logistics.

Thanks zzcoopej.

Side query; does anyone know whether the included portable charger for the 2014 PHEV (which has a 15A plug) actually draws at 15A? I have read that it may actually just charge at 10A.

I am wanting to charge it from a 10A socket so it's good news for me if it doesn't actually go above 10A (I will of course use a caravan adapter with appropriate breaker).

Yes the 15A charges at around 10A and the 10A at just under 7A. I tested this some time back with a commercial calibrated instrument.

Thanks Johny!

I don't suppose there is any means to tell the charger/vehicle to charge at a lower rate than the charger's maximum rate? (I know this is a feature with other vehicles).

Hi everyone
I've just become the owner of an ex-demo 2019 outlander phev. I've connected it to the watchdog app and if I'm interpreting it correctly the battery SOH is at 77%. The car has done 7000km so I'm surprised at how low this is.
The car gives me 52km predicted kms when starting but will drop very quickly for the first 5-10km.
Should I be concerned about this?
Thanks for your opinions.

This doesn't sound right. How many actual km are you getting?

My outlander (2015 model) does the same thing so probably not. Also when it switches to fuel the total distance to empty plummets.

77% SoH doesn't seem right, certainly a warranty job if it is

Hi,
Earlier this year I bought an ex-demo 2019 Outlander PHEV with just over 7000km on the clock. The Watchdog showed a SoH of 78% for 34.3Ah, but on the Battery Condition detail screen it says that 38Ah is 100%. So 34.3Ah would be roughly 90%. The active trip screen seems to show this more correct percentage. BTW, the car has now done 15500km and the Watchdog shows the SoH as 32.6Ah.
