I was not sure about what to use, so I took the largest off-road sponge that I could find from my dealer, because I didn't want to obstruct too much the airflow.
I'm pretty confident that is ok, because sometimes I hear the fan running, but after some minutes it stops, so I guess the fan is still able to cool down the battery.

At first I thought about using paper as Toyota is doing nowadays, but I couldn't find the "right" one for filters.
After having purchased the foam, I thought about recycling a face mask, but it was too late...

Funny thing about the foam, it's quite had to exhale through it, but I can inhale almost as normal.

Better make sure you install it the right way round then  :D

Maybe your sponge filter employs Nikola Tesla's unique one way valve design?

Are the rear ducts both air-input or is one in and the other out?  Anyone know?

Hi,
to answer your question, here's a excerpt from a document detailing the breakdown of the Jazz electric parts:
" The figure shows the flow path of the battery cooling air being drawn in through the intake air ducts in the cabin and next to the rear seats (Ⓐ), then enters through the ducts in the upper lid of the IPU (Ⓑ), and is evenly distributed to the four batteries. It flows down the battery module from top to bottom through the upper branch duct, passes through the exhaust ducts at the bottom of the batteries, and is then drawn into the cooling fan and discharged from the vicinity of the rear bumper (Ⓒ"

No, bms will protect the battery by limiting the amount of power that the car can draw or put in it.
You could find some situation where the car will use more the combustion engine instead of going in EV mode.
