Option for a second hybrid battery

[SgtLip]

Not an engineer or scientist by any stretch. But my question is WHY can't an all electric vehicle recharge itself? You can plug it in but as it runs it recharges too. If a Hybrid can recharge the battery when braking and coasting why can't an all electric do the same? The thing could drive coast to coast and back without ever having to plug in.

The ONLY reason I can think of is there wouldn't be a need for fuel, or plug in stations which means somebody isn't going to make money.

Asking for a friend...

That would be perpetual motion. It is impossible to do.

EVs can recharge themselves with regenerative braking. You still have losses due to drag, friction, and power delivery/conversion inefficiencies so even if you drive up a hill and regen all the way down you can't recapture it all.

Thanks. A guy can dream right?

Why doesn't Elon Musk solve that one instead of wasting money on a rocket ship? Just sayin'

Maybe because Musk can't violate the laws of physics...

Entropy (which is NOT chaos) causes energy to be distributed more and more into every possible mode (stretching, vibration, rotation etc) eventually it all becomes heat. So no system can run perpetually.

I would assume since the Escape, Fusion and C-Max have PHEV that the Maverick will get it too, this is why I'm leasing this Maverick, I'm sure in three years the PHEV will be out.

End of the decade for the tech, longer for the product at mass production.

I really am hoping for cab on a sled to dominate. Need to recharge? Swap the sled. Want to upgrade from 2 door to 4 door? Swap the cab, keep the sled. Want a power or range boost? Again swap the sled (batteries and drivetrain)

But no one asked me.

That's a cool idea! A whole module line of vehicles? It would be neat if they could develop a swappable battery system like we currently have with power tools. This would really cut down the need to spend a lot time recharging. Of course there are lot of things that would have to be over come, like standardization of batteries, storage at station, swapping mechanisms, etc.

Standardization of ANYTHING will never happen. Just look at the number of windshield wiper blades that are available. Tonneau covers is another. They tried to standardize cell phone charging cords but it failed.

Wiper blades! That's sooo true! Every time I go to replace them on my '04 Ranger I have to wonder why there needs to be so many different versions! I'm all for options, but something like 10 different version is a bit over the top!

Not true. Think gas stations. Fill nozzle standards are different for diesel, to prevent cross-fueling.

This is exactly the same thing. Every car has to fit every charging station for BEV to work. Until then, the HEV paradigm works for me.

This has kind of happened with certain platform vehicles in the past. I am thinking Mercedes and Volkswagen both had situations where they were so common that when engines required maintenance, they were swapped out and rebuilt into crate motors that then went through the same process. This happened when they were used as large scale fleet vehicles like taxis IIRC

I could see something like this happening in the future, unless battery recharging capabilities become quicker. I'm not sure if there are or what limits how fast a battery can recharge. I do know from my electronics courses that the faster current moves the more heat that's generated so that would be one limitation that comes to mind.

Certainly not an idea I originated. Something similar is being invested in in Si Valley: https://www.caranddriver.com/news/a35717014/ample-battery-swapping-station/

Well, even Apple caved to USB-C now, for a lot of its products. Here's to hoping for sensible standards for anything, I'm skeptical as well. It will probably take a government requirement. The EU seems to capable of forcing certain standards better than other places, for better or worse.
