I don't think it's paranoia. Given the internal temps that Kiev has posted it's a valid concern. I've gotten the blower airflow optimized and my wife is out of town this weekend. so I should get the bracket jig together and a few brackets made (she calls things like this "goofing off" so p...

Beginning to look like bonding a finned heatsink to the case with the air blowing over it and perhaps some means of extracting that trapped hot air under the rear deck might be indicated ... jray3's initial list isn't looking that far-fetched. :geek: Yeah, I don't think a heat sink is in order. It ...

OK . . . so does this make sense? Looking back at the numbers the lowest coolant temp and case temp numbers were both achieved with aggressive air cooling the charger case only. If the coolant temperature is lower then the components that Kiev has just pictured on the aluminum heatsink (troubleshoot...

While driving, the waste heat loads should be higher, yes, but there is more than just the radiator fan at work. The turbulent air in our motor bay has to provide some cooling as well, compared to the hot stagnant air during a recharge. I'm just glad I never got around to making that rear belly pan...

During the course of dismantling jay's charger i discovered that the 'clear' plastic sleeving and black heat shrink tubing on the inductor and transformer wiring had somewhat melted and fused together. i don't know at what temperature that would occur, but it is likely greater than 360 F. i've neve...

seismic seems to have left. Bummer. Anyway, I'm dropping the car off at the mechanic on monday and he will give me a quote / fix it if its not too costly. I will let you know how it plays out. Thanks for keeping us in the loop. It's valuable information that should get recorded for others who run i...

Do you have a picture of the charger setup in the 2012? It sounds different than the 2014.

There must be much more heat generated when driving the car, cooling the motor and the inverter - I can't believe the cooling system that handles that cannot handle the charger alone. In your tests, do you think you were moving as much air through the radiator as the stock cooling fan would? If the...

There is an OEM fan on the radiator at the front of the car - Any thoughts on just making a mod to use that fan? Many ICE cars have 12 volt cooling fans behind the radiator which are energized using a thermal switch on the radiator tank - When it gets hot enough, the fan comes on for long enough to...

Aerowhatt, what did you pick up as your fan's 12v power source, activated only during charging? Right now it is temporary, separate 12 ah AGM. The DC to DC output is right there and easy to connect to. The negative will go to ground (likely to the bracket for the blower). Fuse (3 amp) right at the ...
