The "removability and replaceability" requirement for portable batteries is a massive win for device longevity, but the Battery Passport is arguably the most sophisticated part of this framework.

By creating a standardized digital record for larger batteries, it provides the transparency needed to finally make a secondary market for "second-life" storage (like using old EV batteries for home solar) viable at scale. It’s a great example of how regulatory standards can help solve the information asymmetry that usually prevents circular economies from functioning efficiently. It will be interesting to see how this shifts industrial design priorities over the next few years.

I hate that kind of thing though when it would come to smaller batteries. This battery passport prevents the user from replacing their car battery themselves easily. Which is entirely in contradiction to this legislation's objective for smaller devices which aims at making self-service easier. But it also links devices to their battery meaning one can not be recycled apart from the other!

It's already causing problems for me there. I often repair small electronic devices, or I remove the battery and repurpose them. For example I use some old tablets and phones with the (often bloated) battery removed, and replaced by a DC-DC converter set to 4 volts or so. This way the device 'thinks' there's a battery. Because most devices with an originally integrated battery will not even power up on USB power if they think the battery is not present or deep discharged. And bloated batteries are unsafe to keep on a charger 24/7 so I remove them.

However the local recycling point is getting increasingly difficult about accepting loose Li-Ion and Li-Po cells. I put them in individual ziplock bags and tape over the contacts but they seem to view them as industrial waste or something. They sent me to the central disposal unit far from the city center but even there they were very hesitant to accept them. And at one point they accused me of running a business because I had 5 different batteries to recycle (I had saved them up because they always give me such a hassle). I think businesses have to pay for recycling or something, I don't know and don't care because I don't run a business.

This in effect stimulates 2 things: People just throwing them in the normal bin which is a waste and can cause fire. Or recycling the whole device instead which is a waste of resources if the original device can still be used.

The battery passport links the device to its battery and only 'approved' facilities can break that link so I think this is a very bad idea for smaller devices when it comes to self-repair people like me. And I will fight that with a passion.

For EVs etc I don't know how that works, I don't use cars nor care about them. But I think even there being able to work on a car at home would be a good thing no?
