I velcro'd a 4 litre box with a a lid to the top of the obc. (Kia NIRO EV.) It holds the KIA evse, the tire patch kit and air pump. Never touch the contents, only for emergency. ⛽
This means that you don't have a gap between them? How warm does it get when charging? I guess it would make the most heat when charging at 7 kW on a sunny summer's day.
Interesting, I know that the three coolant loops in the Bolt uses automatic transmission fluid as the coolant. I would've expected the Kona to do the same but I guess a glycol water mixture would be sufficient so long as the level and concentration was regularly checked.
@MrAbletospeak Apparently, reading must not be your strong point as I had explicitly said the Chevy Bolt used automatic transmission fluid as the coolant and I would've expected the same approach be taken, though a water and glycol antifreeze mixture would also work if the levels were frequently checked and the concentrations maintained, so in essence my guess was already stated for those who are literate as being the ATF especially as an oil based coolant would not be conductive while a water based coolant would be hence the video saying water cooled is a bit suspect (do you really want 400 to 800 VDC water cooled).
@MrAbletospeak Yes but my post said I had expected the same oil based approach as the Bolt used. The "I guess" was a concession to the questionable use of water cooled mentioned by the video. You are still failing in comprehension.
@MrAbletospeak Sigh, demonstrating your illiteracy again. The video poster said water cooled, I said that I had expected oil cooler as with the Bolt but conceded that glycol water if carefully monitored would work as a coolant. All you're doing is den narrating illiteracy in first missing out that I had expected oil based and only conceded water cool might be an option but not the one air had expected. You do understand that reading requires comprehension and it is the comprehension that you are repeatedly failing.
You could have used a 3mm bar and filed the ends down to 2mm, Also I would have also placed a bar across the inside of the Frunk to make it a bit more rigid. Also A frunk with a lid would have been a help too.
Fair play that’s pretty cool! Not sure about the fruit but as a place for cables (that are hard wearing/water resistant anyway) that seems like something Hyundai should of done anyway! Logical place to keep them instead of under boot floors etc
Somebody should sell the 3d printed parts as part of a kit. A Frunk would be a goof place to put the granny EVSE and any adapters such as ones to use an RV power socket or a Tesla level 2 charging station and the air compressor and tire sealant kit. It's amazing that Hyundai didn't set up storage for those items in that space.
Might want to check your owners manual (page 5-160 if I remember correctly), it seems that storing stuff in the front can void the warranty. If you bring it in for service you might want to revert the frunk to stock.
I am totally perplexed why so many Kona EV owners seems to want to bother putting a frunk in? As I have posted before, Hyundai avoided a frunk for reasons of affecting the cooling of the motor below in that area. All you are getting is a max of 1.8 cubic feet of storage? In a dirty outside temperature environment.
We've had a few months now to see if we actually use this space. Perhaps I can help with your perplexion! The Kona has about 330 litres of boot space, and the tub I put in is 30 litres (about 1 cubic foot). 330 litres sounds like a lot, but in practice it is tiny! When we go travelling we have the boot filled to capacity, sometimes with heavy stuff. There is some space under the floor of the boot, but that is not practical to access if you have anything sitting on the floor. So previously, we'd put our charging cables on the floor of the rear passenger area. Our charging cables are often dirty, so we'd clean them off before we went on a trip. Now, we use our froot to store our charging cables. We typically have an EVSE, an extension cord and a type-2 AC charging cable. These all fit comfortably in the 30 litre space, and it doesn't matter if they are a bit dirty. As for cooling the motor, it has a liquid cooling circuit which uses a radiator. My tub is placed on top of the charger, which is on top of the motor controller, which is on top of the motor. In theory the tub could affect the cooling of the charger, which is why I place it up on stilts to allow airflow.
I like your ingenuity but I don't see how this is a benefit. You have to go to the bother of unlatching the bonnet from inside the car every time you get your charging cable (which is the only thing you'd really wanna transport in the front given its depth) More hassle than just getting the cables from the boot.
Strange comment……what is the difference between pop the hood or open the car on the back?. It’s equal the same “bother” . but when the car is stuffed with suitcases or groceries then you get the benefit of the Frunk 😌
I personally don't use the "granny charger" and either charge at a fast charge station - which has it's own cable or my home level 2 station, which also has it's own cable. So, you would just be looking for a convenient spot to store it for the few times in an emergency you needed it. With the styrofoam insert out of the trunk (boot) you have quite a bit more room. We don't have single use plastic bags here anymore, so this spot is great for my reusable shopping and produce bags. The frunk would also be a handy spot to put my emergency gear in case of a winter breakdown.
Only thing I put under the hood is a rat scattering device. Plenty of room in the trunk and back seats to put my junk without looking like a weird mechanic constantely popping the hood to fiddle with the engine or in your case keep my fruit warm.
You put a plastic box on top of a component that gets very hot. I am concerned that this plastic us not thermally stable. The plastic is not heat resistant. Your car does not have a heat pump fitted to it. Very strange.
The Australian Konas did not get the heat pump. Very annoying for people like me in a cold part of Australia! Indeed, the charger can get warm. I've left a decent gap between the charger and the box, so it shouldn't heat up too much. I imagine that if it is hot enough often enough then the box may become brittle over time.
Built it and installed. Has been working great with a bigger tote with a lid. Thanks for posting this video. It led me to the 3d print files.
Great idea! Looks like enough space for a spare wheel. (Years ago I had a Ford Grenada - the V6 was so short they put the spare in front of it...)
I was thinking the same thing! th-cam.com/video/LYC_qUShL_M/w-d-xo.html this guy managed to put one in the trunk

The OBC is water cooled, it doesn't get any more than " a little warm"

I made a video about the temperature, check it out th-cam.com/video/58gJkdz2br4/w-d-xo.html

I just installed my Frunk. Thanks so much!
Good opportunity for someone to offer a replacement grp hood cover with a storage compartment built into it...

My kona came with a froot tub no need to create one. back of the manual shows you how to fit it.
That's cool!
I assume you bought it just now? Which country?
What is length Width Height to box?
652 x 413 x 163 mm
