I get the cost, but it should be an option to upgrade any current EV to this new style battery.

It’s not needed in today’s EVs.

I’m thinking less in terms of lifespan and more in terms of range and charging time.

You shouldn’t have to upgrade your entire car to get a 600 mile range and 9 minute charge time if all that’s needed is better battery tech.

Two questions if that’s the reasoning: how often are you driving 600 let alone 300 miles? How often are you out of range of charging, if at all?

Charging at home makes range not matter. It’s not gas, you’re just always charged up.

The object is to get people to give up gas cars, you do that by providing a better range and a “refill” time roughly equivalent with sitting at a gas pump.

And, yeah, vast areas of the country do not yet have good access to charging stations:

You’re missing the point: it’s not like gas, and can’t be compared as such. If you have a home charger, you never need to use public charging except when road tripping, because your car charges within 4ish hours, or overnight if you have a slower charger. You cannot do the same with gas unless you just top off at the gas pump every day.

I’m not trying to get into charging deserts right now - frankly, most people do not live in them, and thus make up less of the EV market at the moment. We haven’t even come close to meeting your given objective of replacing gas in populated areas. Anyway, this article is about a 600 mile solid state battery that will only be in luxury $200k+ cars, if at all. Not charging deserts.

Not everyone can have a home charger. People living in apartments and condos won’t have access. Heck, even people who do have their own homes will have to upgrade their electrical panels to allow for charging.

Until everyone can charge at home, it all boils down to how much range a car gets and how fast it recharges, which is why this new battery tech is such a game changer.

Again, the people that can’t have a charger at home will not be able to afford this. It’s not a game changer, it would take higher powered chargers than the ones that currently exist, making your whole “charging desert” issue more problematic.

The solution isn’t prohibitively expensive 600 mile range (are you still saying you need that on the daily?), it’s more chargers.

Not true. Before we bought our house we could have easily afforded an EV. We didn’t buy one because we had no place to charge it.

After buying a house, we had to do other upgrades before we could even think of adding a charger, like upgrading the electrical panel from 100A to 200A, and even then, there were other priorities like a new roof and solar panels.

What I don’t get is why you’re so averse to the basic premise of EV owners being able to upgrade the battery tech in their vehicles to get a superior range and charging time.

As it stands right now, range is inadequate and varies greatly with operating temperature:

pbs.org/…/cold-weather-can-cut-electric-vehicle-r…

“It’s well known that EVs lose some of their travel range in the cold, especially in subzero temperatures like those that hit the nation’s mid-section this week. Studies found that range loss varies from 10 percent to 36 percent.”

The average range on an EV is around 300 miles, so losing 10 to 36% of that in the cold is no good, especially when it takes longer to charge in the cold as well. With a 600 mile range and 9 minute recharge, that’s less of a factor. Even if it takes 2x as long to charge in the cold, that’s still less time than it takes to charge a standard EV in good weather.

Every EV owner should have the option to upgrade to this new tech for better range and faster charging. Especially since the batteries are designed to be replaced ANYWAY.
