Hahaha, everyone need to passed the regulation except one national backed brand <you know who> can get certified under table no matter what.
Conspiracy aside, most fire issues are not battery design itself. It is manufacturing defects. Looking at battery structure, you can see the margin of error is super thin.
Sample sent for test is of course passed, but who is the unlucky poor felle.
Coming CATL gel based electrolyte "condensed battery" is the revolutionary until "forever coming soon" solid state battery arrives to mass market.
The gel is impossible to get lit at all.
That explains why insurance and car makes are very conservative towards any dent or scratches of the main exterior battery casing....
But still, a national standards is still something that should be applauded, gives the industry a focus to try to meet and reduce the risk on that specific area of risk. I'm more positive on this aspect as china wants to uphold the image of being the grand master in EV (although of course there are quite some issues with deleted negative comments or userids get wiped out when they comment negatively for some selected EV brands)
Condensed battery really sexy lah....i also drool when reading through the specs, just not sure the cost and which car make/model will apply it. Somehow it was MG4's semi solid/liquid battery that got rolled to mass consumer market.
CATL need to really have quicker integration and collaboration with the car makes to put in their new gen batteries. As time goes on after BYD fully rolled out their 2nd gen blade battery, refreshing and releasing car models using this new gen battery and mass deployment of their flash charging station, CATL's response to BYD's mass push does sound more of marketing "reminders" of their prowess and 刷存在感 instead of something that is readily and mass availability.
After all, how good you can produce but majority of consumers don't get it, not relevant at the end.

EV battery production no doubt is involve in certain polution, but the production process keep evolving. Those retarded people do not that battery isn't appear now but many decades. Battery recycling is a long existed business and recycling isn't any issue.
Electricity isn't green? Bear in mind those advanced countries like Japan, Singapore, Korea, Australia etc they rely on fossil fuel, coals or nuclear to generate electric. Those countries with great public transports need more electric. Electric efficiency is much higher than fuel powered vehicles. ICE cars highest is 45% thermal efficiency while EV car energy efficiecy always in 90%.
2 aspects to look into
Firstly, coal/fossil fuel energy generation is no doubt polluting. But the energy "extraction" has higher general efficiency due to concentrated and focused process of energy extraction (they can set it to operate at the most efficient state; while vehicle engines need to operate in wide range of rpm, driving behaviour and external environment, fuel types etc), and also the pollution mitigation is "easier" to implement/manage and control as again, it is done in a single location. Vehicles are on the road, on the hands of many million individuals, making it much harder and less cost efficient for pollution mitigation. And engines itself has limited thermal efficiency, and those are measured at the most efficient operating point, not really the real average lifetime efficiency of different operating conditions (as opposed to power generator to always adjust to the peak optimal range). Also, some power plants have the feature of capturing exhaust heat, upping the thermal efficiency further.
Secondly, there is another secondary benefit of EV. Imagine the environment of schools where hundreds of parents are waiting to drop off or pick up their child at the school entrance. If most of the cars there are EV, imagine how little noise there is, how little exhaust fumes that are wafting in the surrounding when cars are idling. In short, noise pollution is reduced, and so are the living environmental air pollution.
