It will be even cooler when active cooling like this means that my battery won't end up like a Nissan LEAF battery with 50% degradation after 6 or 7 years. This battery is already 5 1/2 years old but only has 7% degradation and still has very low internal resistance when I measured heat loss a few weeks ago. As the battery ages, the internal resistance increases, so you will have higher energy lost in heat from a high power output like driving up a hill, but that isn't the case here. Plus this is only a 21.6 kWh battery so going up a hill would discharge it at over 2C, for example. Very well engineered car.
@@BrandonKipp What's the mileage on your i3? I drove a 2014 REx recently that had 32k miles on it and the battery was giving 75 miles of range and when I charged it up it read 93 miles of range but after driving it for less than 10 minutes the range read 71 miles.. The battery is reading between 17.3 and 16.8 down from 19kw useable.
@@mamadouaziza2536 My i3 is a 2015 with 23,000 miles on it, and the usable battery capacity is still between 17.2 and 17.6 kWh, which is pretty good. The range rating definitely fluctuates a lot depending on how you drive.
@@BrandonKipp 17.2 to 17.6kwh is damn good because the car only had about 19 to 18kwh useable when new. One could never get the full 22kwh from the battery because of the buffer. Only 22k miles after 5 years? Thats good too! You could get $15k for it if you sell it now.
@@mamadouaziza2536 Yeah I actually was really surprised when I found out about that too. I am continuing to take care of the battery as I actually only charge it to 60% and usually don’t discharge it below 40%. I just manually unplug the car since you can’t set a charge limit. I actually recently bought the car for $15k with 17,600 miles, but I have been doing lots of road trips and tests with the car (the road trip videos are also on my channel), so it already has 23k miles. And I also think the usable capacity was 18.8 kWh so that would mean I have 7-8% degradation after 5 years, which is great as you said.
Its the fan and AC condenser making that noise and it usually happens when you charge up the car immediately after driving it all day. The battery is hot. It can also happen if you use DC fast charging.. Its always best to allow the car to cool down before charging if you can.. Also, it may be a good idea to over night charge outside of your garage because batteries seem to get hot and exploded in a ball of fire.. Happen to a guy in the UK with his i3 and its happening with the Chevy Bolt and with Teslas.
Yeah I also find that the active cooling activates after using the REx for a while. I haven’t heard about the stories of the cars catching on fire from hot battery packs, is there a news article about it anywhere?
@@BrandonKipp Its all over the automotive world news about the Chevrolet Bolt, Chevy has ceased selling any Bolts and have recalled all Bolts from 2017 thru 2019 because of a possibility of the battery exploding. The i3 fire is here on TH-cam. Teslas have caught on fire at Super Charging stations.
@@mamadouaziza2536 Yeah I just read about the Bolt, and I am surprised that it’s such a serious problem now, since there weren’t any problems before until the Bolt’s were a few years old.
So, I shouldn’t worry about this noise? Mechanic found no codes. Several videos say this is normal, just started to hear it today.
Oh yeah it’s completely normal, that’s the sound that the cooling system is supposed to make. It’s the sound of the compressor.
@@BrandonKipp Thank you, so much, for your response!! Great info!!
Very cool!

Never heard that sound on mine though.....
It only happens when you have been driving the car in hot temperatures and you plug it in before letting the battery cool down.
