The Car Care Nut has a video on this, the fan sucks air from the right corner and it goes over the battery packs and down and out the bottom of the vehicle, and somehow it is protected from water coming in that way.I can't find this online but is there a diagram of how the air flow for the traction battery go after starting from the right footwell of the rear passenger?
How hot is the interior of your car?It seems to support that but I don't see an outlet unless it's the entire bottom that's opened. I'm looking for an outlet to perhaps add a switchable suction fan to support the blower to solve my current warm traction battery issue I'm coming up against every 5th drive. Been in lockdown so I've driven 30km in the past 5 weeks and experienced heat soak & inadequate cooling performance not related to filter.
I can tell you how it works in a Prius. Maybe the Rav is similar. With the Prius the warm air from the battery flows into the spare tire well area (under the floor of the cargo area, then out a vent on the left side just behind the left rear wheel. There is no ducting to bring the air to that vent but air has to go that way because the cargo floor prevents it from going out any other way.To answer my own question (maybe) I took the rear seat out and it appears the air flows out the top of the left side of the traction battery and not plumbed anywhere else trapping the air under the seat with a very little bit leaking into the rear luggage compartment. Anyone else know of any other idea of other vent outlet?
Use a screen so air flows but mice don't.So here are the pics. The vent is covered by duct tape as I try to prevent the mice from getting in, so far unsuccessful. I'm not worried about blocking the vent because I've removed the cargo area floor, so there is plenty of room for the warm air to dissipate.

I do plan to do that.Use a screen so air flows but mice don't.
So the battery just vents into the hatch area?That vent you’ve circled should be a series of shutters (like a house) that just allowed air to pass when the doors are closing and open/close freely. It’s got nothing to do with the air flow output of the traction battery.
