Hi I know Brian post a topic on this but I just wanna make sure. I just got the car 2 days ago, is the fan suppose to run the whole time the car is charging? I am currently just charging on the regular 110v right now!

Well you are supposed to let the batteries cool before plugging in.. I normally plug in and then remember to come back after 30 min to unplug and let the fan stop and then plug in..
Which turns the fans off..

although I have had the fans replaced after they burned up so I am not saying this is too effective.. Maybe wait 30 minutes before plugging in?

I've to use the same procedure.
Plugging in and some time later, unplugging and plugging in again will always stop the fan.

i did wait for the car to get into sleep mode and plugging it in but the fan come on immediately. Maybe I need to try unplugging it and replugging to see what happen. That just sound stupid that we would always need to do this, hopefully the new 6.20 will address this.

During the town hall meeting, they promised, that starting with 6.20, plugging, unplugging and any action before and in between will not bring up any fan or CEL issues...

At least that's what I understood....

For now when you come home and the fans are running let the car go too sleep takes about two minutes the gear selector lights should go out at that point plug the car into the charger .
Check if the fans come on after that and let the forum know.

I park it left it alone for 20 mins, came back to charge it and the fan came on again. I also tried the unplugging method for 10 mins and plug it back in, but the fan still came on.

My understanding is as follows (just what I have gleaned from forums and Fisker town halls, not an authority)...

There are at least three independent cooling systems in the car. One involves the ICE, and one the battery. Can't recall what the other is.

At any rate the fans for these systems are all triggered by (?independent) thermostats. They may continue to run after turning the car off if the temperatures of the various systems call for it. Furthermore, the battery does heat up during charging, so if it heats up enough, the fan for the battery cooling system will come on during charging.

There seems to be a "feature" in the current software that if one of the fans (or possibly more, not sure which) is running when you plug in the charger, it/they will continue to run during the duration of the charge. I have found that if I wait until the car goes to sleep (about 2 min), the fan usually goes off and if I plug in at that point it may run for a brief while, but does not run for the duration of the charging session. Other than when I have plugged in during the first two minutes while the fan is still running, I haven't found my fan running when I next go to use the car (usually next morning).

On the recent town hall meeting the Fisker engineers indicated that they may be running the fans more than is necessary with the current software version and this should be addressed in the upcoming 6.20 software. Even with the fans dialed back I suspect that they will come on from time to time especially when charging in warm ambient temperatures, and/or if there is residual heat burden from a recent drive.

If your fan always goes on and never goes off, you should perhaps have your dealer check it out.

HTH.

I left it alone for an hr and try plugging it again this time the fan stayed off. I guess the battery cooled down enough for it not to run. But before this it was running the whole duration of the charge.

I'm now having the same issue, I let the car sit for two hours and when I plug in the fans start, I unplug they stop. This repeats each time I plug in or unplug, any new ideas?

I think it's related to the heat this time of the year. I have noticed the fans coming on almost immediately after I plug the car in and they seem to stay on until the car is finished charging and then they kick off.

Thank you, If that's the case my fans will be on for over 14 hours as my battery is at zero. I cant imagine this is normal.

My car was just updated with 6.28. When I brought it home the fan was running. I waited until it stopped and plugged the charger (110). The fan came on. Unplugged- the fan stopped. Plugged - again on. Only when I locked the car did the fan stopped. Anybody else with 6.28 and this issue?? What a pain in the a..!

Most likely the fans came on when you plugged in the charger because the battery was at a temperature where charging was going to require some cooling. It is not a bug for the fans to be running while you are charging.

I hope you are right. It is hot in New York and I was running the car on ICE. Yet is there not a concern that the fan will burn out?

I think Dennis is correct. The fans will come on when charging. Mine started as soon as I plugged the car in and stayed on until after I went to bed, but my car was charged as usual this morning. Also, I wouldn't be concerned with the fans burning out. I'd be more concerned with the battery overheating and losing life if the fans weren't running.

In last month's owner call Fisker's head of Powertrain Engineering stated that they are overly aggresive in running the fans in order to protect the batteries. He said they planned to fine tune this going forward.

To Clarify some of the fan issue's the HV battery has a cooling system which uses the large fan center one under the hood or the engine fan we know it as .

The inverters use two cooling fans one on each side of the front corner of the car were the black intakes are located behind them .

The ICE fan aka engine fan will come on when you plug the charger in if the battery temp is high .

The fans or the Low temperature fans located behind the intake are the ones that shouldn't stay running after you let the car go to sleep and plug the car in . The ice fan will stay running until it cools down the battery it actually uses a chiller inline with the coolant hoses

Hope this helps some

Thanks. How does one differentiate between the ICE fan and other? Different sound? Location?
