New Energy Vehicles (NEVs) in China

Lethe

John Cadogan is an Australian automotive "content creator" with a background in mechanical engineering. Over the last couple of months he's done a series of videos on the challenges of EV battery fires, particularly in the context of the Fremantle Highway ship fire. In this most recent video he argues that what EVs need is a standardised access port into the battery compartment for direct delivery of water, brine, or other useful material to the affected cells. At first glance this seems desirable, but also quite challenging to implement given that nobody is going to want to come within close proximity of an EV in thermal runaway to fiddle with e.g. a screw-on port like a traditional fire hydrant connector. The port would need to be accessible from several metres away using perhaps a lance-type implement, and ideally that port (or ports) need to be accessible from several different directions and potential vehicle orientations. My first thought is that you might need some kind of intermediary pipe connecting the battery compartment to an easily accessible port on the exterior of the vehicle. The Chinese government would obviously have a considerable role to play in any such standardisation.


(Not particularly relevant, but in terms of the Australian EV market, Cadogan's current perspective is MG thumbs-up, BYD wait-and-see, Elon Musk is a wanker. Cadogan places great emphasis on reliability, parts availability, vendor support as being important than the often minor differences between the vehicles themselves. BYD is still an unknown quantity in Australia from this perspective.)

Xpeng & NIO both at around 15k. Not so great. a lot of these guys are really just dependent on that initial excitement over a new model to get sales

Li Auto is different, it is selling 10k in all 3 of its models and gaining steam monhly
big battle ahead with AITO

Remaining sales from September. GAC Aion & ChangAn did much better than I thought. Good month for NEVs
