Parts needed for ChaDeMo upgrade for non equiped cars

[MickeyS70]

It just occurred to me that the DC model also has battery chilled air cooling from the AC, does the non fast charge have this cooling ability?

Good point, no, there isn’t, but it’s possible everything is already in place to keep manufacturing process universal..

You know, having been part of manufacturing for over a decade, particularly in electronics, this makes sense,

But also, since this car was built so economically, it may not be the case.

Its always a choice isnt it?

Choice/ Effect	Pro	Cons
Universal	Simple, faster, mass-produced-discounts	All the same price, un-affordable to some, limits market range
Custom (options)	broader range of customer, cheaper with less options, upgrades produce revenue	incompatibility with models, more parts, more expensive the more features, each option is more expensive due to limited production

Is there an obvious place where I can look and see like : Yeah there is the vent! etc? stick my head under the car, around the AC?

Update: I can clearly see from the passenger side where the vent bypass for the battery would go , but even with a bore scope I could not confirm it is operational.

What i did found in my ac ducts where spiderwebs, dust and possibly the origin of COVID-19

There isn’t a whole lot to it, some extra ducting which you can get from a donor car and a motorised changeover damper which is controlled by the AC control unit

As far as I know the car blows air into battery during all charging sessions. At least mine does

Here is the mod to redirect A/C cooled air to the pack,

And a post showing the Chademo pinout and the relay under the rear seat,

There is also an older thread about some cars not able to DCFQ due to an additional check made by the newer Chademo stations. The miev firmware does not know about that check function and the stations will not turn ON.

Sandy I was mistaken. I do not have the ventilation for the AC cooling of battery.

Seems like the possibility is getting further and further away

Yes the car is filthy I know.

I think the green connector on image 6 is C111 of the EV-ECU, looks like CHAdeMON wiring is missing?

i would take out the knee-shredders while you are down in there.

You’re not missing much, 1&2 is all you need from a donor car plus the ducting that goes into the pack,

What about 3? I don't see that place where the equipment would attach.

Also the tubing inside the battery, will it be there?

I'm starting to think just drive to Canada and buy the whole junked car , lol

It should already be in place to direct the airflow downwards, add it to the list if it’s missing

Also the tubing inside the battery, will it be there?

There isn’t any if I remember correctly

Actually, not a bad idea…

Only if you have the "cold weather package" does it get the cooling duct if you dont have DC quick charging

@siai47, thank you for reminding us of that. Great to hear from you again!

Forgot about that, it actually connects to an opening in the lid of the pack and trough some additional ductwork to 2 in post #31.
There are already LHD and RHD versions of the battery pack, what are the chances that they kept the ductwork inside unchanged and just put a blanking plate on the lid to keep it waterproof?

 

[Joel_1885]

The only person who would know is someone who opened a non DC fast charge version battery pack.

But being a plastic piece, maybe they all have it.

Later I will use the borescope to peel back the floor of the car and see if this hole exist and where it leads

Mitsu was surprisinly stingy with their manufacturing cost/benefit, but some CHAdeMO components are found in the non-DCFC cars. For instance, the release cable for your CHAdeMO door in the left rear corner terminates inside your RIGHT rear quarter panel, and the missing release handle and cable actually crosses under the carpet to that opposite corner of the car!
Having started life as a RHD gasser made for some interesting compromises!
