German/European supply chains are making huge jobs cuts due to struggles in NEV transition

This is why EU and US are afraid, their existing part suppliers and their downstream counterparts, bar tyre and glass, are not transitioning to EV parts because they have been stuck on the ICE gravy train for too long to make a change. A fast shift to EV means a total wipe-out of an entire system of part suppliers and the jobs, economic worth with it.

no, the issue is because GWM tank series has been massively reducing prices. Tank-400 already cut price by 65k over the past few months to generate sales.

lols at some point in time they should realise that chinese passenger car market is stabilising at 30m unit yearly. rushing to the bottom only kill the margin for everyone and stress the income of workers.

Do we have a thread for general EV technology?

IEEE Spectrum has an article on an Oak Ridge designed wireless EV charger that can charge at 270 kW. I don't really think the tech is specific to the US since is a collaboration between Oak Ridge and Volkswagen along with funding from the Department of Energy, Hyundai and Stellantis.

Cutting the cord has been a longtime dream for EV charging, but it’s been stymied in part by anemic charging rates. Now, Oak Ridge National Laboratory (ORNL) has succeeded in juicing a Porsche Taycan EV sedan at

The Oak Ridge system pairs a magnetic resonance transmitter pad with a receiver mounted to the underside of the car. The system’s secret sauce is its polyphase windings—lightweight electromagnetic coils arranged over a coil to generate a rotating magnetic field that eliminates current ripples and field cancellation.

The system is compact on both the transmitting and receiving ends. Onar says the powerful 270-kilowatt receiver fits into the space that Porsche carved out for a potential 11-kilowatt wireless charger on future versions of the Taycan. The electromagnetic coils in the receiver are less than 50 centimeters in diameter. ORNL said its system is the world’s lightest wireless charging unit on a per-kilowatt basis—at 7.5 kilowatts per kilogram, versus 1.9 kW/kg for the Brusa company’s wireless system, which delivers just 22 kW of power overall.
