EV charging speed is not a matter of technology

Chinese brands are constantly advertising that their charging speeds are overwhelmingly superior,
but you need to know the truth.
Of course, it is not entirely unrelated to technology.
The better the battery, the higher the charging speed it can handle,
and controlling a battery to accept higher current even if it is the same model
is indeed a form of technology.
However, simply being able to charge at high speeds...
that is not technology. It is just brute force.
If you just allow it even if the battery lifespan is destroyed,
it will charge quickly.
It is not that Samsung or Apple lack the technology to support 100W charging.
Chinese phone manufacturers all claim ultra-ultra-ultra-fast charging.
Does that mean their batteries are premium while Samsung and Apple's are low-grade?
Samsung and Apple prioritize battery lifespan and stability,
whereas Chinese companies often operate without regard for long-term consequences,
using ultra-fast charging marketing simply to show off their technical prowess.
It is the same with electric vehicles. Being somewhat fast is a legitimate spec.
But those that are ridiculously fast...?
They are the ones that have given up on battery lifespan.
You can consider them far from practical for real-world use.
If you look at data coming out of China,
even while using low-quality batteries,
Chinese cars charge at speeds similar to or faster than cars using premium batteries
(and, of course, pushing power consumption excessively during driving also has a major impact).
There are countless cars where the battery health has dropped below 90%
after only 30,000 to 50,000 km. It is a level of defect.
You should not compare those who operate without regard for the future against those who do
based solely on numbers and specifications.
