Poor battery performance

[jaapv]

As I said, why don't you guys have your battery capacity checked? At 20.000 Km mine was 36.3 Ah which is normal, most cars are in that range. (baseline is 40 Ah)
A battery capacity check costs 9 Euro over here, official service price by Mitsubishi.

Hi,
That battery capacity sounds more like the 12v capacity but I expect you know what you are talking about (usually do). Please explain.
Kind regards,
Mark

It is the battery performance figure that gets supplied with each service. (or should be) at a supplementary cost of 9 Euro.

40 Ah * 300 V = 12 Kwh

All cars are (or should be) checked before delivery and should exhibit a capacity between 37 and 38 Ah at room aka workshop temperature. The next check point is at 20.000 km ( or, I suppose, something like 15.000 miles or whatever the UK service interval is). This will give a figure between 35 and 36 approx, as the falloff is the highest in the first period of use. The figures of each individual car are relayed online to Mitsubishi Japan to keep track of the performance of the battery.
40 Ah is the theoretical max capacity that gets entered in the record as a zero point at 0 km.

I have had a similar experience as well, with battery charge range never getting above 24-26 miles and an actual range of 15-18.
Before jaapv makes some helpful comment regarding driving style...Dealers PHEV specialist been out to examine my driving style and standard daily journey and also thinks there should be better range as I was driving it better than any others he had seen!.
Really interesting and helpful what gwatpe is saying that it is possible that battery quality/capacity can vary, but suspect dealers may not be aware of this as when they have checked they cannot find a battery problem.
I am getting the dealers demo for a week so will see what difference this makes.
gwatpe - when checking full recharge level, will I need to start a charge from empty to get the kWh reading, or if recharged from 30% capacity will I still get the reading?

Sorry for not responding. Since the forum went down it is almost unusable when responding to a post, so I have not bothered to look as often as I had.

I suspect that some dealers may have the neccessary MUT3 diagnostic tools that jaapv mentioned. Here in Australia, Mitsubishi Motors Australia did the test on my battery, and the maximum capacity was 36Ah instead of 40Ah, NEW.

The reduced battery capacity does affect any drive of more than 20miles or 35km.

New PHEV has over 50km battery range and my driving style has not changed. Noticeable improvement to REGEN as well.

I would like to see every PHEV come supplied with a battery quality/capacity test report in the user manual, or service record.

I do know that the MUT3 diagnostic test is only a guestimate and not an actual measured Ah, but is a dealer number and this is very important when it comes to warranty.

Hi jaapv, i went today to the dealer to analize the battery with MUT3 test and the result was 34,6 Ah on full batttery 329 volts and 15.000 km? .... there was others issues that arent well but they have to ask to the Mitsubishi Portugal technician for more information!? What do you think about this Number 34,6 Ah x 329v= 11,38KW .
Thanks

Mine was 37,8 at delivery and 34,5 at 22.000 km

better than mine, 13,75% lost from original pack is to much in 22.000 km and even worst in my 15.000 km !!!!

I've been driving the outlander for more than 120.000 km and about 80 % of that was electric. I fully recharged the battery twice on a regular working day.

I'm a very conscious driver. Partly because I'm worried about climate change but also because my boss pays for the electricity and I have to pay for the petrol. So I pay close attention to the battery performance every drive.

Since the last 4 months I noticed a steep decline in battery performance and not only because of the winter. Compared to earlier winters it has definitely less range. I'm now getting only 25 km and that is without AC and in close distance to large vehicles while driving.

I also noticed that earlier when I complete empty the battery and then charge it only receives 6-7 kwh whereas a year ago it would still be 10 kwh.

What do you recommend me to do? The car is from feb 2014.
I'm dutch, btw.

Make sure you get the Ah reading. Do you have an OBD adapter? If not, where about are you located?

 

[djmoscow]

I filled mine up yesterday. Full tank. Empty battery (0 EV range). The overall range was showing as 354 miles. I drove 15 miles and the range was showing 272....that's a ridiculous underestimation....especially since I'm driving steady in ECO mode with a PHEV box and trying to regen as much as possible and coast in B0 too....

What was the original capacity? Note that it will never be 40 Ah, that is a nominal value.

The only thing that an be done is "Mitsubishi battery smoothing" ... that is a slow discharge and charge process, in order to fully balance the battery pack and as well re-initialize the battery parameters like expected battery capacity and voltage level for different state of charge

Anyhow .. don't expect miracles out of it ... the PHEV firmware is relative smart on keeping the pack balanced and updating automatically the needed parameters, so ... unless they make a mistake on battery smoothing, the possible gain is marginal.

What is important is to know if any of the cell in the battery pack is much weaker then others ... in this case maybe something is wrong in the pack and it could be fixed/improved

 

[Bert]

And then we have the battery cell smoothing procedure and the BMS reset procedure as separate services they can apply to the battery.

I think they have done a full reset on my BMS as it went straight back to 100% SoH with 60.000km...
