Fisker Claims it Will Build an Electric Car That Charges in 1 Minute

Get back to me in 2023 with something real and maybe I'll be impressed. Until then it's just hype at best.

You'd probably also need some inventive cooling to keep the battery from catching ablaze during charging.

I have similar difficulty seeing how they will get internal resistance down low enough to prevent a large rise in temps, I pointed to that in a previous post but they can side step a bit.
The heat has to get out somehow, completely insulated wont work, metallic external is dangerous...
So it comes down to forced air cooling or water. Water is a tricky thing to use and remain safe in an accident.
Unless there are some decent none metallic heat conductors that could attach to the cars chassis, it looks like forced air cooling.
I can see them attaching an air hose as well as cables.

Ultimately it will need to be very low impedance and have good cooling.
I think the 1 minute charge wont be realisable for a long time, 10 minutes is a tough call.
Especially for longer range and/or more powerful cars that need a larger battery, otherwise it is limited to a subset of the market.

ps the charging station could be underneath the road to keep cable length short.
Alternatively have a tall building (with a long wind tunnel to get air speed up) and surrounding charge points .
 
I see "Fisker" and all I can think of is "Fiskars"

It has to be changing the battery out. How hard was it to just get some 240+ lines run and then 480 at places? Not many wanted to pay the cost of it.
 
Folks they said capable of not that the infrastructure would support doing it ;). Pigs could be capable of flying...if they had wings!

Actually a battery that can charge at that rate is a bigger leap than the infrastructure.
 
I can imagine them getting around the household electrical infrastructure issue by having a large charger mounted to the wall that's full of large capacitors. The caps could charge slowly on a 120/240V circuit over the course of a few hours, and then you'd just need a cable that could dump all that power to the battery.

Anyway, I assume this "1 minute charge time" is more of a theoretical, best case scenario figure, and the average household user would be able to charge the battery in 15-30 minutes from empty to fully charged. That's still very fast.

Pretty much. You don't need to have a functioning prototype for a patent, so you can just put gobbley gook down and claim you've filed for the patent (heck, they may even grant it, like they usually do).

A little PR spin and you'll have the naive investors lining up.

It's an age old trick.

I call utter BS on this.

For a 500 mile range they'd probably need ~150 kWh battery.

Considering real world charging efficiencies of ~85%, they'd need to apply ~175 kWh in a minute.

That would require power delivery of ~10.5 megawatts for the duration of that minute.

That would be like having your own small power plant for a minute, not to mention there not being any power interface capable of handling that.

Assuming a power factor of 1 (this never happens, but lets just assume) you'd need:

- 87,500A at 120V; or
- 50,480A at 208V; or
- 43,750A at 240V... etc.

Let me point out here that the highest power NEMA connector (us power plug standard) is 50A at 240v. This is one 875th of the required power.



You are probably right, that they are referring to something like this, but this would be disingenuous. This is not "charging". This is "replacing".

This is some sort of scam and/or wishful thinking.

This is what I was going to post. It's either only capable of charging that fast in theory, or they're using some super-capacitor array that charges like normal over a 4-8hr period and then dumps it all to the car battery when plugged in.

And even if that is how it is done you don't want people messing with 1000s of volts circuits as at that level if it shorts its a bomb and blows you apart
 
A household-sized array of capacitors could do double duty as home-defense system. Tie it into your fence line...or your door-knob. No unwanted visitors! (Okay, at least not the first unwanted visitor...)
 
So they have a 160kWh battery. That can be charged in 1 minute. As in 60 seconds. Meaning you have to charge it at 50kA from 220V?

I've read some non-related articles on new battery chemistry and charging technologies coming down the pike, so it's definitely possible. How soon though? That's the question.

Pretty much this.

That being said, this sounds like a pump-n-dump to me.

does that term still apply to a stock that isn't sold on the open market? Maybe they are trying to attract private equity but question still stands.

My take on it is you can recharge on the road fast but 1 minute is daft.

At home you are looking at a much longer charge time.
It will take 20hrs to fully charge from flat with 2x 240V 13A plugs attached, assuming no losses and assuming its safe to use 13A.
Realistically 24hrs to fully charge which is not much use.
It will need a much upgraded supply to homes and expensive systems to support faster.

This will always be the problem with electric cars unless they are weedy or have a low range.
I cant see this being solved directly.
I reckon they are going to end up using something like fuel cells burning hydrogen to generate electricity.
Either in the car or the charging station at home.
 
This is what rich people do when they want to spend a lot of money, but don't want to spend any of their own money. They convince a bunch of other dumb rich people into giving them money. Its called investing.
