Not likely there will be all sorts of support hardware for active cooling
and processors controlling that.
Basically its not just the battery there is all kinds of support hardware and programming.
could it be done probably would it be cost effective most likely not.

Swapping the 2021 phev lithium ion battery into 2019 rav4h. It is reportedly much more powerful than our nimh battery.

It’s a complete system. Changing battery would change everything. The software would need to be changed. The battery may not physically fit. Wiring will be different. 2019 generator probably too small to charge a battery that large from ICE.

May be a lot easier to just buy the PHEV? :)

There’s a company in Europe that supposedly can upgrade the battery in an e-Golf to greatly extend its range. But the upgrade is crazy expensive and the car has to be reprogrammed.

While you're doing that why not also replace the wimpy Atkinson I4 with a '06-'12 V6?

I’m all for thinking outside the box. But these cars are literally a total synergistic system where everything is carefully selected and tested to work together in harmony.

Well maybe except for the fuel tank & gauge. Something went haywire in that department.

Yeah it you want to replace it with the same battery it might be simple . But you are talking about a different type of battery that probably will take up different space and have a different cooling heating system probably driving different electric motors with different controllers and software maybe not and since there isn't even a Prime available now how can you speculate either way.

Okay, so it's a little involved. But still it shouldn't cost more than TWO '19 RAV4Hs. Think of it - then you could potentially have TWO reluctant gas tanks. And I'm sure there are many more unforeseen advantages!

Nothing is impossible for those with lots of money and no common sense. What are the assumed gains you imagine for such a swap?
Actually, it’s easy. All you gotta do is take all of the body panels off the hybrid and stick ‘em on the ‘21 PHEV. Swap done!🙄

Glad to see some smart bud comments. When the nimh battery needs to be replaced it would be nice to have a more powerful alternative. Would be sweet if it is a simple drop in with software upgrade.

After the ten plus years of ownership that might have the battery fail...odds are most of us would be looking for a newer chassis with upgraded tech.

No way there is going to be a cost effective "drop in".

Most of us not all of us will be looking for a new chassis. :)

If/when the nimh batt needs replacing, the rest of the car will probably also need to be replaced. Surely by then, the Dilithium Chrystal conversion will be perfected!
More powerful? How much more powerful and why? Faster quarter mile times?
You don’t really imagine Toyota is gonna offer you a simple drop in conversion. Charging system the same for both? Gonna have to put a charger port and associated wiring to the outer fender. Is there a normal 12v battery in PHEV? How about size/location/cost of the battery?

The Prime lithium battery would have more capacity but not more power, you would need bigger electric motors for more power. So you might as well ask whether the larger motors form the Prime could be dropped in. Again the answer would be no.
