Porsche Demonstrates Inductive Ev Charging at Iaa

I guess that doesn't have the sexy Nikola Tesla factor.

Taking five seconds to plug in isn't a big deal to me. However, my wife (with her own separate EV) does often forget, and it's a bit maddening at times. Of course, we have a long enough cord that we can park in different places and always charge, so a wireless charger wouldn't fix the problem if we had to switch around to use it.

Of course, you could have some driver aid informing them how to better align themselves. But still, you will always waste energy in practice, and at the scale of automobiles out there it becomes unreasonable, no?

Also, that "efficiency" measurement is not overall Pout/Pin. It's merely measure of charging speed and they do touch on that mentioning the lack of a "break-out box" etc. to determine the actual numbers.

One can absolutely achieve the same charging speed with induction charging, but with a much higher power input and at a greatly reduced vehicle efficiency due to the much higher on-vehicle mass dedicated to charging the battery.

This is also a bit of rigged game as they're using the oldest wired-charging infrastructure against the latest wireless. They do touch on that. The older wired standard has a much lower power-factor duty-cycle.

That said, it, otherwise, was a good test as they also took into consideration ambient temperature and battery heater.

What's the deal against hydrogen? Toyota made a car that made it to market, it can't be that dangerous if it was sold in certain regions with extensive safety testing procedures. I know the problem is getting hydrogen at the pump station but other fully battery dependent cars have had that same issue before.

I'm sure hydrogen has other problems (conversion efficiency?) but what about ethanol? Better than gasoline, no? At least 40% less greenhouse gases out of the tail pipe, and its production is pretty mild for the environment compared to batteries. It wouldn't make cars that much more complicated either, and you could "easily" convert your ICE car. Of course, at the scale we are talking about the gains would be way lower given a 5 year timespan vs batteries

Hell, there are others.

Such a weird set of events dictating the future of cars ngl, some of the alternatives may have had come sooner if someone focused there (I know Brazil has some minimum ethanol requirement that seems like a good idea while transitioning).

this amount of extra heat would probably need in car AC to kick in draining probably another 500W
