EU is likely going to put tariffs on Chinese BEVs pretty soon. My personal take has always been that BEVs are merely a ploy by the CCP to gain marketshare in Western markets. Beyond that, there is no real interest by Chinese automakers, and likely they will abandon BEVs the moment it becomes convenient for them.
An Apple Air Tag uses a lithium cell to power it. Small few mA rechargeable type lithium cells can be charged by a 3.3V regulator, low reverse current blocking diode, and a resistor to limit the charge current. The wires for the switch in the handle for triggering opening the charge port door could provide the power for the 3.3V regulator. ...
... This is a circuit the lithium cell maker showed how to make in an application note. I use it for charging backup batteries for the digital clock chips in my art pieces.
Doing this would allow the air tag circuit to be built into the charger handle, and it would work for the life of the cord, not just the life of the Air Tag battery.
Those Air Tags could be computer monitored for location. When one moves it can be automatically flagged and investigated.
Fuel economy rules will basically follow whatever the average fuel economy of new cars will be. It's pretty clear that Biden has mostly given up on forcing BEV adoption via this mechanism.
The idea that the West will make our own batteries is a mirage. These things will always be made in the cheapest countries. All other factories will likely shut down.
