The second-generation Blade battery can charge from 10-70% in just about five minutes and from 10-97% in under 10 minutes. More impressively, the company showcased the battery charging flawlessly from 20-97% at -22°F (-30°C) in just about 12 minutes, only around three minutes slower than it charges in normal temperatures.
…
The EV was plugged in at 9% state of charge with 93 kilometers of range (57 miles). In 9 minutes and 51 seconds, it charged up to 97% with the range prediction in their gauge cluster displaying 1,008 kilometers (626 miles). This is likely calibrated for the China Light-Duty Test Cycle (CLTC), which tends to be more optimistic than the Environmental Protection Agency (EPA) test cycle in the U.S.
Still, these charging speeds are way faster than the 20-40 minute charging stops on the latest EVs in the U.S. The new BYD EVs can basically recharge in nearly the same time it takes to refill a gas car. Even the new 1,500 kilowatt (1.5 megawatt) Flash charging stations are arranged like a traditional gas station for cars to quickly drive in and drive out.
Every time I’ve seen someone test this hypothesis - as in doing a long-term experiment with the specific purpose of testing whether fast charging harms battery health - the result has come back that it doesn’t make much deference at all
It’s also worth pointing out that every battery is different and apps like Accubattery are imprecise. It’s entirely possible that your 100% and your friend’s 93% are actually exactly the same. It’s also possible that their battery would have displayed 93% when brand new
I crossreferenced my testing a lot though I cant 100% guarantee what I found is accurate.
Though I can say this: I don’t think built-in health monitors in phones are worth a damn. My gran’s phone was showing at 100% health when accubattery was at a whopping 73%. Testing the old and new battery, the new battery held up just about 30% more time than the old one on youtube playback.
I did other things that I wont get into
This is why I chose to trust accubattery and pretty much invalidate other testing in my head. I know it’s one single test and sample but this is my information and I trust it at lleast for now.
