Contantly cooling while charging and driving

Sat Apr 04, 2015 11:28 am

HI,
I have a 2013 SL and recently it started to constantly run the coolant fan in the hood while charging and also when I start the car. The battery heat indicator has never gone above three bars so it is not a heat problem I assume. Any ideas ?

There is no cooling of the battery pack so battery temperature is not a consideration... The best guess is that it is the radiator fan for the liquid cooling loop. If it is running constantly, there is a problem.

I have heard that too. I am guessing it is to keep the converter inverter cool while charging.....

You always hear the coolant pump running when it is charging but the fan should cycle on and off. It is a very different and much louder sound.

Yep, I've heard the coolant pump always running when charging but have never observed the radiator fan (or any fan) running while charging. Then again, I hardly charge at home and mostly charge at work. But, I have sometimes checked on my car while it's charging.

As for radiator fan running while driving, yes, it ALWAYS comes on for me if I either turn on the AC or heat on my '13 SV. OP, what if you turn those off or simply turn the HVAC to off?

To pump coolant through the the onboard battery charger to cool it.

I did not know it was water cooled. I see now that they are running a coolant line all the way to the rear of the car where the charger is located. Seems like it would have be easier to air cool it back there somehow.

I'm sure that running a couple of small coolant lines was actually much easier than providing the amount of air and ducting that would have been necessary to cool it by that means. It also makes for a smaller and more reliable charger.

Hi have exactly the same problem, I have a 2015 Leaf SV with 5000 miles on it, they decide to change the VCM, i had to wait 1 month before receiving the part, they change it monday and unfortunately this have not solve the problem, so they ordered an other part yesterday and suppose to change it today. So im driving a stupid Micra for over than a month now.

The Nissan service is very very bad, they never call for feedback, yesterday I open a complaint at Nissan Canada, I hope they can fix an arrangement for me.
