In the Netherlands, capacity is guaranteed to be 65% of 40 Ah = 26.0 Ah for MY14, MY15 and MY16 and 70% of 40 Ah = 28 Ah for MY17 and MY18. Both during 160.000 km / 8 years (whatever comes first). It is clear some countries do better, some do worse. I am aiming to build a list per country, preferably backup by official Mitsubishi documents and / or websites.

Here is what I have so far. Anything you can add?

Netherlands

Minimum 65% of 40 Ah = 26.0 Ah for MY14, MY15 and MY16 or 70% of 40 Ah = 28 Ah for MY17 and MY18. Both during 160.000 km / 8 years (whatever comes first)

Finland

Minimum 70% of 38 Ah = 26.8 Ah for MY14, MY15 and MY16 or 70% of 40 Ah = 28 Ah for MY17 and MY18. Both during 160.000 km / 8 years (whatever comes first)

Norway

Minimum 70% during 160.000 km / 8 years (whatever comes first)

UK

Minimum 70% during 100.000 miles / 8 years (whatever comes first), but only for MY16 and beyond

Nothing.

I have not found anything like the above yet for pre MY16 cars for the UK but is it safe to assume that all EU countries have the same warranty...whilst we are still with you of course! :cry:

Indeed, I would think / hope so to. Although, that could work out two ways.

In the USA, it's not just Mitsubishi that doesn't offer degradation battery warranty - they join Ford, Fiat, and Tesla in this regards: https://www.plugincars.com/what-you-need-know-about-electric-car-battery-warranties-132884.html

As that article brought out, Tesla is in a safer position for this issue due to the larger battery capacity. Bottom line for Mitsubishi PHEV owners in the USA - protect and baby that drive battery: https://www.evolutionaustralia.com.au/top-5-ways-to-preserve-your-battery
 
So would I be wrong to assume that mits engineers would only allow 80% charge when the battery is full? That would make sense since there is no setting to stop at 80.
 
Mitsubishi have already taken best practice into the design of the battery management unit.

What you see on the dash does not show either the top end or the bottom end of the battery's capacity, it shows the working range.
 
I've learnt this recently by using a public charger for the first time this week.

Battery shows empty on car yet when you plug it in its starting at 30% which must be the point at which the usable capacity begins. It'll only charge to 80%.

My interest was to see the actual kW that I could put in the car so I connected it to the UK 3 pin plug through a smart socket. I could put 7.4kw only into the battery from "empty" before it was full. As my battery shows its degraded down to 85% that sounds about right. This makes me slightly happier that whole the range is pants at ~22 miles, I'm not spending 12kw of electricity achieving it!!
 
This raises a question. Does the battery indicator on the dashboard still show "full" after charging even though the capacity is lower for those with a significantly degraded battery? I.E. will those of us too non-tech to be able to use one of the plug-in analysers :oops: notice anything to show the battery is degrading, other than declining range?

SoC is expressed in relation to SoH. So, even when SoH is 75% you can still have 100% SoC, so full indicator on the dash. It is all relative.

It also means that the bottom buffer (at what energy level does the engine start) gets smaller. Same SoC but lower amount of Ah.
 
No capacity guarantee in Australia. I specifically asked about this, and the reply from Mitsu was as follows:

Please accept our apologies for the delay in our response.
We can confirm the Traction Battery is covered for 5 yrs / 100,000km (whichever occurs first) warranty.
The battery in the PHEV is no different to any other battery and will deteriorate over time. It will deteriorate in proportion with the usage of the vehicle as battery life depends on the usage and maintenance of the battery when both in use and in storage.

According to users who have been tracking battery performance with PHEV watchdog, it appears the full charge goes up to 4.10 volts on full charge, which is about 92% full capacity (please correct me if I'm wrong).

There are some interesting threads in this forum that suggest some improvements can help:
