Room temperature superconductor:

Unfortunately it loses its superconductivity in a magnetic field.

 

Hi,

Yeah I saw that ship tragedy, nasty.

On the lighter side of life, Toyota supposedly came out with a 900 mile solid state battery for their cars. Supposed to happen 'soon'.

 

Isn't any battery which stores that amount of energy in that volume going to be dangerous?

At least the superconductor is should be cheap - it's mainly lead phosphate

 

Death by government edict?

Hi,

I am not sure what you are saying, it seems you are mixing batteries with superconductors?
I was not addressing your post i was just mentioning that there may be new batteries for EV cars.

Is the battery dangerous? Well, it is solid state, so I think it is safer than batteries that are not solid state. I don't have all the facts yet though so I'm still a little in the dark too. They didn't give a release date yet either. It's supposed to be a breakthrough in EV powering technology, or simply battery storage.

 

Death by government edict?

Is it possible to discuss without politics? Who knows. Let's find out.

Well, I wasn't deliberately. I commented on your solid state battery comment, along with a further comment on the superconductor.
But it's not such a daft thing to mix - could superconducting cell interconnects reduce battery heating?
I'll shut up and go to bed.

 

In my defense, that was the other thread. But so was the point I was trying to make.

My bad.

Hi,

No that's ok I just thought that the two subjects are usually discussed in a mutually exclusive way, but being able to wire them together with zero Ohm wires would be really good too, as well as wiring to the motor. Heavy current drops larger voltage with regular wire, and I could imagine how high the current is for these EV motors.

 

 

It makes be wonder about using the Channel Tunnel. LPG cars are banned, but electric cars aren't.

 

Don't they call that a business model? Car catches fire people need new car, rinse and repeat.

Only if the people don't go up in flames with the car.

GM delays EV truck production at Michigan plant by year

General Motors Co (GM.N) said on Tuesday it will delay production of electric pickup trucks at its plant in Michigan's Orion Township by a year as the No. 1 U.S. automaker grapples with flattening demand for electric vehicle.

The move is the latest sign that electric vehicle production and demand may not be as strong as forecast. GM had been set to begin production of the electric Chevrolet Silverado and GMC Sierra in late 2024 at the suburban Detroit plant. The company said the plan now is to start it in late 2025.


GM said the change was being made "to better manage capital investment while aligning with evolving EV demand" but said the move does not impact its battery plant plans. GM said in July battery production at the Ultium joint venture plant Ohio has been hampered because "our automation equipment supplier is struggling with delivery issues."

 

We do not have any of those cheap and tiny Chinese EV cars YET!
A photo of a parking lot in China shows a few of their EV cars and a couple of EV bus's on fire.

 

What does the connector for a 1MW charger look like? That's 1000V at 1000A. How can the socket tubes be small enough to stop the general public sticking their fingers in them?

There are a trillion nano-tubes. Elon calls it "GigaPlug". </sarcasm>

Make it big so they on stick the fingers in once when powered.

III. HV Touch Safety
High voltage (HV) touch safety is a measure intended to prevent living objects from contacting
conductive paths that may have a high voltage and/or high temperature. Globally many governmental
bodies require IPXXB for high voltage connections that are outside of a passenger compartment. IPXXB is
defined by IEC 60529 and is intended to prevent a defined “finger” from contacting any hazard surface.
MCS never intends to have any high voltage exposure when the connector and inlet are not mated. Based
upon the experience with the CCS standards development and the lessons learned toward broader
adoption of the CCS interface in regions with other guidelines related to touch-safety protections, the
MCS design followed these learnings and is constructed to provide IPXXB level of touch safety.
