Computer firewall on entire pack which seeks to prevent low cells from self reversal or otherwise overcharge destruction when recharging: areohead speak.

In normal speak: tends to prevent the long imagined nuclear fireball while sitting at a fast charger or self destructing the usefulness of the entire pack. ($$$$$)

Since these packs are essentially a thousand series paralleled "C" lipo cells you kinda want limits.

Some additional/new info on the Lightship (maybe). It's at least recently published, and the YouTube video in it is newer too.

The trailer has a strong converging jet, downward and inward, that the tow vehicle lacks. That validates my teardrop trailer design.

I wonder if oil pan 4 the Corporate imperialist has figured out the contribution of the pusher configuration yet.

I like how except for a couple wisps, all the flow seens to go underneath. Hmmm. Computer edited picture , where is the smoke source? Diffuser would work wonders, perhaps.

I don't think it's smoke, but [is] low pressure rendered visible.

' flow imaging '

I think that they're just denoting 'separated/turbulent' flow around the aerodynamic system.
If the F-150 Lightning had been 'streamlined', and the gap was closed and 'tailored' to create an aerodynamic 'singularity', rather than the 'double-frontal area' structure we witness, then, we wouldn't see that 'disquieted' flow.
'Viking', behind 'Spirit of EcoModder' was striving for this 'singularity' condition, and creates a system clean enough that it at least compensates for 'being there,' not registering at all at the fuel pump. The same would go for at the charger with a BEV.
AeroStealth's IONIQ-5, if pulling Viking in California, would be returning 504-miles range, off it's 77.4-kWh pack, under EPA HWY-esque conditions. And this would be without the benefit of any onboard TT propulsion system.
