If the car is always charged fully from the AC supply, the BMU estimate of SOH is probably quite accurate.


I am not sure about this statement HHL. Now from the person on youtube I posted above says:

"Had the 2018 phev since Feb. After 20.000 km and battery capacity down to 93%according to watchdog, had car inspection and they suggested battery reprogramming, and they did a dbcam procedure. Since then battery capacity upto and remains at 98,5% and have driven 1000 km. My garage(Germany) doesn't understand all these problems, so the most important thing when buying a phev, which I love and am very happy with it.,is the 3xperience and quality of expertise at your garage. The extra education of the mechanics is expensive so my garage tells me."

Now we cannot tell from this if the person used DC charging but reading what he said made me go and check my new April 2018 PHEV and saw that the SOH was 91.84% with only 12,823 kms using EVbatmon. So according to the BMU I have lost approx 8% in approx 9 months with no DC charging and we have been babying the new PHEV's drive battery far more than my oldest PHEV.

Speaking of which ie my oldest PHEV you asked me back in the old Evbatmon thread I started:

Same here... works a treat.

Use an old Nextbook to run it. Very impressive....

My battery % is 91.4% (car built date is Mar 2014, 11,000km)

Care to share your info?


Sure.

Battery condition 90%.

Car built Feb 2014(bought April 2014), 31,415kms


Now this was posted Sun Dec 27, 2015 so nearly 2 years after it was built my oldest PHEV that we did not baby is approx the same as my new PHEV that we do. :roll:

Do I think my new PHEV is degraded this bad for real? No I do not. I think the BMU is being very pessimistic on the new PHEVs as some around here have noticed including the person I quoted above.

Will I bother to get my BMU recalibrated at this stage? Not sure. I may wait to see because it is not effecting the range we need while EVing but I would love to know for sure like the person I quoted above just to satisfy my curiosity. :geek:


Interesting about the new one's SOH. Anyway, I do think the less dealers fiddle with the car the better it is ;-). As for a certain Youtube enthusiast's exploits, I do think the engineers who designed this car deserve a bit more credit. When you look at the few recalls, all of them quite minor, it is an incredible achievement with a car of this complexity.

"certain Youtube enthusiast's exploits" Who you talking about? Don't be shy. ;) :lol:

Yea I think the engineers have done a great job as well. Is the PHEV perfect? Not IMO. But as an design engineer myself I know we cannot make everyone happy. We have budgets and sales projections to consider as well as technology and physical constraints etc. But we try our best to make the product better as technology gets better etc.

Well it all changed when anko (yes the same anko you still see here floating around sometimes) decoded the Canbus. Now we have multiple apps to show our SOH of the drive battery and other things.
Recognition. Thank you :P ;)


:lol: That would my pleasure anko. You did good work. 8-) Though sometimes I curse you like when I checked my new PHEV's SOH. :lol:

:lol: :lol: #metoo

In Australia it "seems" to be 80% after 10 years. At least for a happy few. As in good will, no warranty ;)


Hi anko. So who are the "happy few" you mention? Is this something I have missed? :?
Auch. I guess you have fallen behind. YouTube 'celebrity' Andy from EVUnplugged Australia has led the rebellion against MMAL and this resulted in his battery (and maybe one or two others) to be replaced on short notice. Not because of warranty but because of goodwill :geek:

He needed about 140 short VLOGs and this is the final one in which he announces the results.

Look like he swapped PHEV for a Tesla...just for a day.

Hi folks,

As my old degradation thread is now 36 pages :shock: long I will start a new one here as the old one has a lot of out of date information.

Now just to catch up of where I am currently with my oldest PHEV's drive battery which my oldest son now drives is we had below 80% SOH (about 77%) in Feb 2018.

After stuffing about with different dealers where the first could not get his MUT-III to communicate with my PHEV I finally got another dealer to get some tests done. It was there where they did a battery smoothing (cell balancing from what I could see) and a Auto Capacity Measured Procedure which empties the battery and measures what it takes to refill it and then adjusts the BMU SOH to include the new result. For me it took the SOH up to about 81% . Now the other day my son and I checked his drive battery and it was showing about 72% SOH so the gain did not last long so I will be trying to get a new drive battery before the 5 year warranty runs out in April.

But will have probably have to get another Auto Capacity Measured Procedure done again though. ;)

Regards Trex.


After getting my oldest Phev's drive battery recalibrated again and the SOH went up to approx 75% and the data sent to MMAL, and been told by MMAL that they will NOT replace my drive battery.

So if you are a whinging German on youtube that moves to Australia and he buys a 2nd hand PHEV, from memory, you get your battery replaced. But if you buy 2 PHEVs brand new and was born and bred here no such luck.

Yep, sounds fair to me. :lol:

I would go so far as calling it a double Auch. :roll:

Hi guys,

I bought my 2015 Outlander PHEV in March 2018 with 26,000kms and it read a battery SOH of 84%. Now less than a year later it reads 76.3% with less than 35,000kms. Does this seem acceptable?

Also, the car is due for a 3yr service and I have been quoted $930, $850 and $680 to do the service (in Brisbane, Australia), do these amounts seem reasonable for what looks like a basic oil/filter change, a pollen filter, plus 'looking at' a list of things?

Thanks

I tried PHEV Watchdog with "KONNWEI" bluetooth adapter. It works otherwise fine, but I can't get it display the "battery condition" page. It's always blank. I waited like 5 minutes in case it was just being slow, but no. Other pages work fine.

However, I installed EvBatMon, it shows the stats correctly. :) It showed 34Ah capacity and 91%, but are these comparable to PHEV Watchdogs values? Pretty good still? MY15 car, registered in 08/14, with 71000km.

I unistalled EvBatMon already, Play store gives the money back if you uninstall in 10 minutes or so.. I'm not interested in using these apps daily, but I thought it's good to check the stats.

Welcome pughev

In Australia, till recently, they did advertise that the Outlander PHEV should not go below 80% of SOH in the car life. Car life has been later stated to be 10y

Some people in Australia (I don't know if they made any legal action, but you might check Andy on facebook or on his YouTube channel) have got an agreement to have their battery replaced for free from Mitsubishi for 10y, if the battery goes below 80% SOH.

You might use this as precedent with Mitsubishi Australia, and in case they would ignore this, contact Andy or other which got the agreement with Mitsubishi.

Since Mitsubishi Australia made a mistake on their advertisement ... In my view every PHEV acquired before the correction, he/she has the right to get a new/replaced battery for free once this go below 80% SOH

PS: I think the main problem of the Outlander PHEV in Australia ... it is to let the car sit with high SOC under the sun or with very hot ambient temperature ... so this can impact PHEV with low km as well with high km ... maybe more the low km models which might have sit plugged on the charger in a hot environment for many hours and many days. Unfortunately the PHEV active battery cooling is not active while the car sit unused
