Increasing/Upgrading - Higher Battery Capacity

[user 5728]

Hope dies last....

Still a few years to go for me before it makes sense to consider a swap to better class batteries. Although, I'm waiting for it.

Just watched a chap on YouTube had rebuilt a higher capacity battery to 19kwh pack

I am not affiliated to him in any way and only came across it by accident I might look at trying to do this at a later date when I retire in 3 years
As I have 9kw of solar on the roof

Thomas is a nice guy, but I don't think he commercialised it.
However I read that there is a commercial solution under development here in Australia, due for release late 2022 -

They already have a iMiEV solution which a friend of mine has -

That clip is over 5 years old - I think we might have heard something by now

Wish I was in OZ when I see that, Those battery upgrades will eventually appear in Europe but I haven't come across any yet.

And why would you want one? The "basic" is merely the same range as the original, despite needing a 50% increase in capacity and if those figures are correct, how can the same battery pack give a longer range in the "extended" version? Something is wrong here, especially as the link talks about these coming in 2023 - er, we are already in 2024 but no live link to an actual product! Perhaps because it is all nonsense

I saw that too, but also noticed that they have an order form with just one price for the Outlander and that they want a 50% deposit. I wonder if they have the product and haven't made the website reflect that or they don't yet have the product.

It makes sense when you know how it works. The reason for the different ranges on the same pack is because one is just replacing the pack with larger batteries but using the stock settings in the vehicle so the car won’t recognize the extra capacity and the extended version uses a CAN Bridge to manipulate the messages from the BMU and trick the car so it can use the extra capacity in the battery so you get more range.

Interesting, so will show a faster degradation if it works, eventually - perhaps we shouldn't hold our breath, yet!

Why do you think it will show a faster degradation?

 

[greendwarf]

Why do you think it will show a faster degradation?

Because, AFAIK the original BMU offsets degradation by using the "unusable" top and bottom margins to try to maintain range. As this mod (you say) gets round that by accessing those margins then the normal reserve is no longer available to mask the overall reduction in capacity. So users will notice a loss of range earlier and at an increased rate. Whilst in practical terms it will make little difference to the overall EV miles driven, it is likely to disappoint purchasers who thought they were getting away with something for nothing!
