Is “flash” the blinding light the car makes when it bursts into flames?

#12BYD's America containment policy to make Americans drool with jealousy. America will still be home to boring vanilla EVs that looked like it was stuck in the 2010s. BYD has a better chance of entering US market by offering tribute to Trump & Co over an inflexible protectionist / labor union friendly Democratic party.

#13Does anyone know if they have looked at how charging quickly impacts the longevity of the battery? Can the cells be damaged by the rapid increase in temperature and current?
Probably a bit but here’s the thing: if charging fast is, well….faster…then people care less if they loose a little extra battery because getting it back is less inconvenient.
There’s a graph i imagine here where slow charging, you want to retain all capacity. Faster it gets, you tolerate more battery loss.

Fast charging appears to damage batteries less than expected. There are lots of reports of taxis which almost exclusively used fast charging with over 200,000 miles on their battery.
Of course that is normal fast charging. Flash charging is 3x or more faster, so that's unknown.

No, it is a marketing term relating to the chargers BYD is deploying. According to the article the chargers can charge a car with enough electricity to provide a range of 400km in around 5 minutes. Another separate, but important, factor is that these chargers apparently work very well in winter and can provide a similar charging speed at -20°C.

There's been a lot of study into this already and the forming consensus is that fast DC charging is less of an issue on battery longevity than was first thought. In cars with decent thermal management systems it seems to have a fairly limited effect on battery lifetime as opposed to natural calendar aging.

#17I'm against BYD factories unless car parts shipped from china are not heavily tariffed. You don't want to allow them to ship entire kits from china to final assemble in Europe. You want them to buy from providers in Europe. Otherwise I'm in favor of massive tariffs on their cars to avoid dumping.

#18As an American, I'm going to be really sad when we miss this transition. Maybe there's still time?
It will happen. My guess is that Canada is BYD’s pilot into the US. They have very similar buyer characteristics and the Canadian tariff deal allows them to enter the market without taking the risks of local factories. It won’t take much to get BYD access to the US. It’s a two-step process: - Toss a million bucks at Trump or wait for a Democratic administration - Build a plant in Alabama/Tennessee/South Carolina/Geor…
A million? 100M only gets you an ev advertisement on the Whitehouse lawn. It will need to be something more like Saudi Arabia's investment in ivanka, i mean the affinity group. 25M a year to his son in law gets your phone calls answered when you feel like Iran is acting up too much.
I am not as optimistic. If that doesn't happen the only candidate likely to let china do as they wilt is aoc. Vance would happily start ww3 with them. Rubio/newsome/shapiro etc will all keep the full pressure of all allies in them, potentially kicking them out of places they already sell.

#19I read an article recently that said something along the lines of “China is pausing on the idea of a BYD Mexico factory over fears of US stealing their technology.” Isn’t it ironic? Don’t ya think? Update: link to the article I was reading: https://electrek.co/2025/03/19/chinese-authorities-delay-app...
