LA FERRARI

I've heard Panasonic ultimately made the batteries, and only did so in small batches which caused them to be extremely pricey. I do not believe there is any 'repairing' of them just yet. Only replacing. Future issues with hybrid Ferrari's have always puzzled me as it's not like some company will continue making these batteries, there has to be a rebuild solution, of which I don't think one exists yet. Anyone?

 

There’s a guy in the USA who specialises in car battery rebuilds who appears in prominent YouTuber car videos (e.g Tvarish). Tvarish was looking to replace his McClaren P1 battery (but decided to remove it completely). He has his own YouTube channel: Rich Rebuilds. Maybe contact him?

 

No rush to figure out how to fix it. New batteries are typically a year or more wait to get one.

 

Rich Rebuilds is who Tavarish was using for his P1. He could probably build you a better, cheaper La Ferrari battery if you don’t care about originality.

 

I happen to know something about the hvb packs.

Repairing a battery pack (i.e replacing defective cells), is not going to be an easy tasks on these: given the high amperage draw, I presume the cells are "matched". I can hardly see how to easily match replaced (new) cells with the old ones that you keep.

If the pack is not matched, under high load, some of the cells will sag, which is not what you want in such an expensive car. Also unmatched pack are more easily out of balance after heavy use, so take much longer to recharge (the bms has to repeatedely stop the charge in order to level the voltage).

Replacing all the cells would be more appropriate. This requires more hours. Also Requesting 100 cells that have the same internal resistance under high load is obviously much more expensive than randomly grabing them. Either you buy direct from the manufacturer, or you buy 4 times the amount you need, select the ones that suit you best (time consuming and resuires the proper testing tools) and resale the rest.
