China Has "Flash Charging" EV's

[Mavster Mechanic]

BYD of China now has EV's and EV "Flash Chargers".

Flash chargers are apparently the next evolution above Super Fast chargers.

On a 500 mile EV:

10% to 70% in 5 minutes.

10% to 97% in 9 minutes.

The kind of heat that the EV would be putting off receiving that kind of current would have to be stupendous.

Just hope that doesn't kill the battery life, and that soon most EV's get a faster charging times for home chargers as well.

It's not just the charger as existing batteries in most EV's would detonate if they were charged that fast due to thermal runaway. The current "fast" chargers already cause battery life reduction.

The BYD Blade 2.0 LFP battery is what enables the ability to offer quick charging, due to its improved safety with high thermal resistance, where that lack is one of the major problems with "standard" EV batteries.

The LFP batteries offer a long lifespan as well as ultra-fast charging capability.
It looks like a game changer that makes other EV's and chargers effectively obsolete.
Maybe rollout of a premature technology wasn't the best way to spend billions.

Both in China and anywhere else that wants to go big with EVs is where the power is going to come from to fuel the EV fleet. Over half of China's power comes from coal fired plants.

They are already upgrading the electrical power grid system and semiconductors for Data Storage Buildings for AI. If Wall Street wants it, and they can profit from it, they usually get it.

They don't care, they have no oil so they are still ahead in their minds. Plus alot of the air pollution gets blown over to us.

Upgrading the grid doesn't add power, it at best improves transmission capability and reliability.
If more power is needed than is available, it doesn't matter how good the conduit is.

The basic issue remains - In an era of dramatic increase in demand, where is the power going to come from? Keep in mind that more power plants have been decommissioned here than built.

We could use some of the 40 million acres used for ethanol production and put that into renewable energy production. Just take 25% which would be around 10 million acres and throw wind and solar on it.

Ethanol is a looser anyway and if we were to "let the free market decide" like some people like to say then production would have stopped decades ago. Without taxpayers subsidizing production ethanol wouldn't be a thing.

Also, we already destroyed the prairie and it's not coming back so put that land to better use.

Alternative energy is great, except when it isn't.
It isn't scalable.

You can't make it sunnier or make the wind blow harder because more power is needed.
Alternative energy can also experience wide scale outages at the worst possible times.
That entire prairie covered in solar panels in your example can lose 95% of its capability with a few clouds overhead. A cloudy day in a heat wave can easily mean a power outage.

Excess power can be stored in batteries, but that is the expensive part of the renewable equation, and to be dependable, that is a requirement which also means less power is available for use in order to divert power for charging batteries when none is produced at night.

I happen to know what I'm talking about as I have designed and built solar stand alone and hybrid systems over the last quarter century. Solar alone is not viable as a primary grid power supplier.

The U.S. grid has 50% more generating capacity right now than demand.

Almost zero power plants run at full output. Many run 50%.

Except your numbers are way off.

Ethanol used 14% of the corn. So 14% of the acres makes sense, right?

54% of the corn was sent over-seas. Much of it was sent to Russia before the Ukraine war. So assuming that we stopped doing that as "sanctions" there is more corn available than ever before.

Funny!

Ethanol gets a dime of government help for every dollar of subsidy big oil companies get. How come you did not talk about oil subsidies?

Big oil is a big problem.

China QC right !
Mount that In Your garage, plug in your new battery tech.
Nine minutes later your EV is at a 97% state of charge or your house is 97% fully involved in a fire.

Cant use it anyway until that battery tech is available so its not an option.

I know you are joking, but as stated above it uses a new generation of battery, maybe stop thinking of it as a battery at all. Think of it as a storage device.

And it will never be for home use.
Commercial use only. Just like gas stations.

I would hold off with any BYD until they improve the quality of the BEVs they currently sell. Their 'burn rate' by self-ignition is higher than desired.
If I owned one, I would not park it in an attached garage. The energy involved to re-charge in such a short while could be pretty destructive if there was any problem. I'll pass.
