Replacing PHEV main batteries - any idea on cost?
Just wondering if anyone knows the approximate cost of replacing the main batteries when the time comes. Mine's coming up to 3 years old now and the max range has dropped by about 10%. I seem to remember reading somewhere that LR guarantees a 70% battery capacity up to 7 years.

I'm hoping by then alternates to OEM batteries may be available which offer greater capacity therefore greater range?

My EV battery, 90kwh would be 40k to replace today. Takes into account 8k to pay the garage to swap the battery.
Reasonably to replace your battery today you are looking at 8/10k at least in Uk.
Battery at 70% means it’s done. In 7 Years I would expect to get new gen batteries with different chemicals, more density and capacity and same volume.

Throw in vehicle depreciation then in reality you are looking at scrap value in the long run.

Even in the e-bike world no third party supplier is making replacement batteries for older models, and they have been around longer.

Modern vehicles are just not meant to be kept. Unfortunately you just have to know when to cut your losses, it also means this is how they will get you into a fully electric car even if you don’t want one.

Thought as much. I'm intending keeping mine for some years yet, so I think spending another 10k in 4 years time will be worth it. Current: MY22 P400e SE

Maybe PHEV batteries will need replacement sooner than BEV vehicles? They work harder. Our EV (Vw) is coming up to 4 years old, and the battery health is still at 100%. The range is the same today as it was when new.

We usually only charge to 80% which covers our needs, only charging to 100% when necessary. Do PHEV owners always go to 100% charge? 2021 Defender 110 X-Dynamic HSE D300 MHEV

A battery health of 100% after 4 years would defy physics. I strongly suspect that number is incorrect.

Yes, PHEV batteries go through a much higher number of cycles but they also have a significantly larger buffer, meaning they don’t necessarily reach harmful states of SoC. Hence longevity should be pretty comparable to BEVs.

With current trends I would expect the vehicle to be obsolete in seven years, so although I have no doubt that much better batteries will be available I wouldn't necessarily expect that they would fit a seven-year-old vehicle.

The technology to the rescue phenomena must have a lot of confirmation bias.

Sure there are examples were technology has solved big challenges: LED lights, consumer electronics, anything with electronics, but there are an equal or more examples where it has lead to nothing: Living in space, flying cars, unlimited energy, various social issues.

I think batteries might have reached this point where we might see incremental changes only. Surely a battery with immense power density, enormous charge and discharge currents and infinite life would have been invented by now.

I also don't see any development towards sustainability in general with shortening of equipment life cycles, no repairs possibilities, software dependence an other planned obsolescence.

Its all a con. In any case society's demised is more likely to come from social media than the environment I think

I disagree!

Firstly, a common misconception is that faulty battery packs mean the entire battery pack needs to be replaced. A BEV battery consists of a large number of individual cells that can be swapped out if any one of them get faulty.

Secondly, second hand BEV batteries are being used for renewable energy storage to great effect!

Thirdly, there’s ALOT of R&D into battery technology, and if you look at EV range increases over the last few years we’ve almost doubled efficiency of EV batteries in a relatively short amount of time.

Lastly, EV batteries are generally extremely durable when treated well.

My dealer hope the warranty will cover the replacement...
the cost of the battery pack (in Italy) is about 13.000 euro + VAT and installation.....

Interesting and disconcerting! My P400E is booked in to the dealers on Monday as I too have an engine warning light, or did as it has now subsequently gone off after 4 days. I will keep the appointment and see if it is related (we have had sub zero weather here over the past week so it may well be battery related).

Did you determine this fault using IID tool or is that a screen grab your dealer gave you?

Both....
IID Tool report same DTC...

Click image to enlarge


DTC Confirmed from Topix and diagnostic routine specific for DTC P0A7F-00

Click image to enlarge


P400e purchased on October 2021.
km 68.000 (about 25.000km in EV mode / 43.000 Hybrid)
Battery cycle 100%-0%-100% about 1.500

Heath of battery:
Power lost: 19%
Capacity lost: 9,5%

Click image to enlarge


The DTC Issue is not (maybe) related to Heath of battery...
19% and 9,5% is not so bad...
maybe the problem is locater in other parameters..

Eerily similar. mine was purchased Sept 21 and has done 67k km but I would say majority of that using battery.

I will ask them to give me the same health report on the battery!!! I presume if I ask them to run the same diagnostic based on the fault code you mentioned I'll get a similar health report? Current: MY22 P400e SE

Heath of battery is a BECM Module Application.
the dealer can do it also without DTC pending...
