USB-C charging law in the EU.
BeBuLamar:
What do you think about the requirement that a lot of electronic devices must be USB-C chargeable?
To do so the BMS system as well as a boost converter is needed for devices that requires higher voltage than USB-C is capable to provide. I don't think it's a good idea to put all that circuitry in the device. I must rather have them in the charger.
wraper:
Law applies only to specific types of devices. It's very unlikely device that needs higher voltage falls under this law.

What exactly do you mean by "charger"? Generally it's an extremely poor idea to move charging controller into a power brick. Wait until customer plugs some incompatible charger and your device explodes and busts in flames. Do exactly that if you want this to happen https://www.beckershospitalreview.com/supply-chain/melting-batteries-3-fires-prompt-recall-of-248k-insulin-devices.html

What would be examples of devices which the EU requires to be USB-C powered, and which run on higher voltages than what USB-C Power Delivery can provide?
TimFox:
This EU press release has a list of objects that require USB-C charging: https://www.consilium.europa.eu/en/press/press-releases/2022/10/24/common-charger-eu-ministers-give-final-approval-to-one-size-fits-all-charging-port/
Question: is that list exhaustive?
Mention is made of a later deadline for laptops.
