What REALLY REALL REALLY gets neglected in this "200 miles of range in 5 minutes of charging!" is...


that is a FUCKTON of power being transferred in such a short period of time. You need a HUGE YUGE YUUUUUUUGGGEEEEE source of power to push that much energy into a battery.

Yeah, I think electric cars are good, and I think they'll get much cheaper and much more practical, in part by things like this battery, and yes, I do think that infrastructure will be developed to do this superfast charging... but I always think it's weird as fuck no one bothers to do the math about how much power it actually takes to charge a battery like that in such a short time.
This, better have a 3 phase plug in to transfer that much juice in 5 minutes.

arent the current charging stations DC for the 400V EV battery?

If you make the plug 3 phase then the vehicle is going to have to have some heavy duty hardware to take 480 3 phase and charge a 400v battery

Also houses dont have 3 phase. most businesses dont have 3 phase

This would be an infrastructure night mare  coupled with the needed upgrade to the power distribution and generation system to supply this much more power.

Houses and business also currently don't have their own gas stations.  I don't see the need for a 10 minute charge at home.  

Why not use a standard charge at home (in the 4-8 hour range) and then design the fast charge at a "gas station" that has the infrastructure for it?  Current stations have huge tanks to store the gas/fuel.  Why not the same principle for electricity?

I don't know but I would guess they have some internal heat dissipation material in the design or the charge fluctuates during the 6 minutes of charging with intermittent shut downs to allow the battery to cool down..................???

Oh and I would assume that they have an automatic shut off when the battery has been charged so there won't be any overcharging???

I don't care if the car comes with its own newqueler power plant and has a plug-in bigger around than an 18-wheeler's tires, the battery won't charge in 6 minutes without burning down the owners house.

So, bringing to the personal-car market a battery for a car with a 200 mile range between changes, and one that can be recharded in 6 minutes is unmitigated...

The DC charging station standard is running the supply AC through a transformer rectifier unit that not only changes the supply voltage, but also converts the AC signal to a DC signal.  Part of the reason for using multiple phases is that you get a smoother DC supply signal with more phases.

I am skeptical given the projected release date.  Everything is delayed and over budget, or some scandal comes out that was covered up for decades or years, etc. Everything was about the nuclear fuel cycle, hence the hydrogen buses and other things that could fuel various industries and other things.  Toshiba had or has an accounting scandal, if you look for it.  Par for the course I guess.

Just a thought, and maybe I am completely misunderstanding the discussion, but what if by “Capacitor battery hybrid” they mean that this new battery has a bank of high power capacitors which do indeed charge in 6 minutes, but then discharge into a more conventional battery, thus allowing the battery to effectively charge while the car is moving, thus negating the fast self discharge time of the capacitors as they only act as a charger?

So you'd burn gas in a generator for hours and hours to recharge a car, when it would have been easier, quicker and more efficient to pour the gas directly in to the vehicles fuel tank?

You'd have to have one hell of a generator on hand to charge a car anyway, let alone charge it in anyway approaching the time that this article claims.

They have a rather low (well, high, relatively) internal resistance that causes them to self-discharge at about the same rate energy is used from them.  That's why they are only used as short term backups, and not even large enough for a UPS.   Once you get above 6V max, they really deteriorate with each charge/discharge and self-discharge, when talking the 400V from lithium battery packs in cars, capcitors are larger than lithium ion batteries, and have lower mAH/cc.

The biggest issue they're going to run into is that our power grid/outlets aren't built for continual 10kW surges when several people in a row decide to charge their car fast.  (Estimated power draw after losses)   Especially during daytime, when brownouts already happen if more than ¾ of customers have AC running.

I always thought a system of capacitors would be great. Lets say you have 4 systems on one vehicle. All 4 systems are are used at different rates being shuffled through. One will always be getting charged from wheel spin. Then once charged they shuffle through.

480 3 phase @ 20 amps would do it, but how many places are going to have that handy for surge use?  Not at any sort of affordable rate.
arent the current charging stations DC for the 400V EV battery?

If you make the plug 3 phase then the vehicle is going to have to have some heavy duty hardware to take 480 3 phase and charge a 400v battery

Also houses dont have 3 phase. most businesses dont have 3 phase

This would be an infrastructure night mare  coupled with the needed upgrade to the power distribution and generation system to supply this much more power.
Now imagine 4 or 5 of them charging at the same time. [the same as pretty much every gas station you go to]
Maybe a stupid question but isn't an auto alternator a 3 phase?

If so, why couldn't that take up the lion's share of recharging the batteries while driving?
Maybe I'm misunderstanding your question, but you can't recharge a vehicle with the electrical power output it generates.

"Lisa, in this house we obey the laws of Thermodynamics!"
There is regenerative braking, and at the power those batteries can take for input, there wouldn't need to be "dump resistors" to prevent too much power from blowing the battery up.  That'd make regenerative braking a bit more efficient, almost eliminating physical brake pad wear (low speeds/e-brake would still need old fashioned disc brakes).    Otherwise, trying to charge while driving would be the same as hitting the brakes.

I always thought a system of capacitors would be great. Lets say you have 4 systems on one vehicle. All 4 systems are are used at different rates being shuffled through. One will always be getting charged from wheel spin. Then once charged they shuffle through.

They have a rather low (well, high, relatively) internal resistance that causes them to self-discharge at about the same rate energy is used from them.  That's why they are only used as short term backups, and not even large enough for a UPS.   Once you get above 6V max, they really deteriorate with each charge/discharge and self-discharge, when talking the 400V from lithium battery packs in cars, capcitors are larger than lithium ion batteries, and have lower mAH/cc.

The biggest issue they're going to run into is that our power grid/outlets aren't built for continual 10kW surges when several people in a row decide to charge their car fast.  (Estimated power draw after losses)   Especially during daytime, when brownouts already happen if more than ¾ of customers have AC running.

The problem is reality gets in the way.  Cars are the #3 worse environments for electronics, behind space and saltwater boats.   The temp swings are huge, the area to dissipate heat is effectively small, vibration and all sorts of other "little things" nobody thinks about.    Right now, the new graphene supercapacitors are showing great promise, in lab tests.    Making them rugged and able to stand high current charge/discharge cycles at temperatures from below freezing to 140°F is a whole different animal.    

Even Li-Ion batteries being a "mature technology", they'll still explode or start on fire if you mistreat them.    Would you feel comfortable sitting beside a box containing 200 MegaJoules of  mostly stable energy in a crash (unit conversion ~ 250 tons of dynamite equiv)?

So right back to using fossil fuels then.

Or, you could use the natural gas itself, compress it, and pump it into a on board tank and burn it in a I/C engine very cleanly without all the expensive turbine stuff.

Wow... a lot of people seem to think this has to be something you can do at home. It won't be. Or they seem to think that if you CAN'T do it at home, then the whole idea is a failure.



Serious hardware, and power, will be needed for fast charging of EVs. They'll have to be like gas stations.

Normally, people will probably charge at home, at much slower rates. The common EVSE (Electric Vehicle Service Equipment - kinda like the 'charger' you plug in at home, then plug your car into, which isn't really a charger, it's just a fancy relay that disconnects the high voltage when a vehicle is not plugged in) at "level 2" uses 2 phase 240V, and can go up to about 7kW.  

So if you get home at 6PM from work, plug your car in at 7kW worth of power (considering no losses) and don't leave for work until 6AM, you could potentially get 84kWh. Accounting for losses, you'd likely get 70+kWh. Given you probably don't commute 100 miles each way to work (if you do, you're in the <10% of the population), you'd have plenty of time to top off overnight.

Most current EVs have several modes, where you can program "Time Of Use" so that your car doesn't start charging until a certain time. There's also "Time Of Departure", where you set the time you'll be leaving, and the car figures out when to start charging. The latter helps balance out local loads, so that the whole neighborhood doesn't all start charging when TOU kicks in.





TL;DR - fast charging will be at specific locations, like gas stations. Most charging will be done at home on slower connections as power is limited at residences.

On the contrary. That new lithium battery would be a big help for them. Their cars currently run off of several thousand 18650 lithium batteries. These new batteries will shorten the Tesla car's charging time and increase their range. I've wondered why Tesla doesn't incorporate solar cells into the roof, hood, and trunk lid of their cars so they would be constantly charging the batteries as long as they were exposed to the sun. Would just require redesign of regular solar cells into an integrated array that could be designed to appear to be part of the hood, roof, and trunk lid.

You just cant get enough wattage out of solar panels on a car.  These batteries could be great, the recharge time problem has been the big obstacle to widespread adoption of EV's.  But the chargers will have to put out serious juice.

The next pie in the sky tech that I hope comes true is a big jump in solar cell efficiency.

Photovoltaic solar can only get to 32% efficient, currently at 27% with bleeding edge technology which means 45 watts/m² electricity.  167 watts/m² is total sunlight energy reaching Earth surface on cloudless day at equator .   The rest is in thermal wavelengths which need to be harvested with the mirrors on the black body to boil water or similar.   Photovoltaic is really efficient if in space, not so much on Earth.    In San Diego, there are 3000 hours of clear / mostly clear daylight per year, a 2017 vintage 1 m² solar panel will create about 150 kWH of power per YEAR (adding in 10% for cloudy days).   Nothing generated when people are at home, peak generation is about 2 hours after sunrise to 2 hours before sunset, though I'm giving those dusk/dawn times benefit of the doubt as well.

The leap in solar technology will be combining Photovoltaic solar with Thermal Solar, through peltier junctions (inefficient 10% of heat power into electric power), or by "cooling" the solar panels with a fluid/gas to expand and drive a turbine like the mirrror farm in the desert.

Agreed.

According to /r/futurology on Reddit (or any other left-leaning green energy totalitarian website), all of these awesome new battery technologies are just right around the corner and we'll all be driving electric cars in a few months.
