Do electric cars need grilles or are they only there for aerodynamic/aesthetic

Their brakes, batteries and even motors still need cooling.

Aerodynamic reasons most likely

mostly aesthetic reasons. because regulations forbid shit like wedges. when you make a car without a grille, even a mock grille like the Model S, you get an abomination like this

>>16833183
Motors and batteries get hot as fuck. Not like an internal combustion engine, but pretty hot nonetheless and they also need to be way cooler than ICE's to run properly.

thing is, porsches don't really need front grilles and they've been doing fine in terms of styling.

like here's a redesign that really REALLY improves it, precisely because it takes a note from prosche's book.

it's just difficult to make something look good without a grill, because without it you have a shitload of negative space at the front of the car you have to design around

wrong, and wrong.

right, and right.

>>16833195
sorta right.

they don't get hot as fuck. they get hot but in terms of total thermal energy lost due to heat, it's a fuckload less than ICE. tesla's battery packs are liquid cooled and they do an excellent job but the problem is even moderate heat in the packs (like 150F) can really fuck them up, hence tesla limp mode.

you can easily satisfy the cooling needs with a ground-facing intake, or a little lower intake slit like the model 3 uses. a full on grill is redundant

>need to be way cooler
but not too cold
>>16833401
telsa also warms the cells up

>>16833426
true, cold cells are just as ass as hot cells, which is why teslas also have a sort of cold limp mode where while the pack is warming up in REALLY cold weather (assuming you didnt plug it in, leaving it plugged in lets the pack heater keep the pack toasty), it doesnt let you use regen braking for a few miles. When the packs are cold they really do not like to be charged and discharged back and forth

seems to me that the current design trends are what hold these things back. headlamps have gone further and further up and around, and grilles have gotten bigger and bigger.

if you took something like a caprice and removed it's grille, it wouldn't look so bad, because of the way the front is designed. Hell, many 90's cars had very small minimalistic grilles, like the Taurus, and looked (mostly) fine.

but modern styling conventions just dont really allow for a decent grille-less design, because like you say, you end up with a shitton of wasted space at the front

the software to keep track of this must be briddy neat
something like 7100 cells to balance and rotate
although it's probably managed per module for cooling and per group for charge

yes there is a good deal of abstraction, but it's sort of a cell-within-a-cell approach, each level with some form of battery management system which can be trusted to keep clumps of cells balanced. Software wise it's not actually -that- difficult desu senpai.

>>16833473
actually that's a really good point, i didn't even consider that.
shit. it's like a perfect storm of awful styling

electric cars are gayboy mommy machines anyway.

it's not even an automobile. no otto cycle. NOT /o/.

Each individual cell for charge/discharge balance, brick for cooling

Pretty sure the radiators for my Boxster were behind the front grill.
And by pretty sure, I mean absolutely certain.
