Re: Upgrading the heating system to bioethanol or Diesel fue

Hi robert,

At 6 % soc battery temp avg was 7.1 deg peak 11 lowest 0 with the peaks on cells 17 and 50,55 the classic double bump temp readings lowest are 31 and 66.

Voltage followed the same pettern exactly peaks of 3.62 and lows of 3.585 my cells are probably out of balance somewhat but overall pretty good. I did not heat the battery but i was driving on the highway at about 80 km/h. I do keep the car in the garage when charging so the battery temp climbs while its in the garage.

Wow Don - you sure pushed it to the limits .
I would be too afraid of waiting for a tow truck in these temperature without heat.

Since you pushed it until you hit the turtle,
Did you have a chance to record how many km/miles you were able to squeeze out from a full charge in those temperatures?
Was that at 80 kmph?

Hi Sandy,

I drove from my place to st bruno round trip. It was 100 km exactly. It was -16 deg C and I stayed there 3.5 hours charging L1 8 amps with the oem charger. On the return the wind was howling right in our face. From the junction of the 15 and the 40 I stayed on the service road at about 50km/hour to make it home with 7% left. Turtling was not part of the plan but i think the winds from the west did us in. We were 3 in the car also.

So 100 km total in pretty bad conditions with 3.5 hours of L1 about 83 % highway the rest on the service road. This is round trip so elevation changes are zeroed out. I had the charger in the car and canion was giving me accurate soc. I started to worry when i was 20 km from home. So I got off the highway, stayed on the service road and kept scanning the rr and the gps distance to home. The last 20 km I drove slow.

It must have been rough in terms of temps for you up there in the mountains this past week.

To us temperate-climate Californians, your weather, and especially the entire NorthEast US blizzards in these last few weeks, leaves me shaking my head. OTOH, maybe instead of the Keystone pipeline we should have a water pipeline heading in our direction...

What a great example showing off the utility of the heating system mod. DonDakin, thanks for the writeup and for posting the CaniOn photos. A 40km/hr headwind (for example) when you're going 50km/hr is the range-killer, not to mention greatly increased rolling resistance in any snow or slush.

Congratulations for surviving turtle (which I have yet to see…)

Those winds were a big factor. We usually experience 3 - 5 C degrees cooler her in the mountains.
You did pretty well with 3 in the car and the speeds you were driving.
This little car keeps on surprising us.

Thanks, Don, for sharing the success story.
For all, in regards of the turtle, you would take the chance in Summer because in case you have to call for the tow, you do not have to freeze as you wait. In the Winter, you do not want to take the chance UNLESS you have the combustion heater, which keeps you warm and allows you to stay focused on managing your driving style to conserve the (electrical) energy and to ultimately complete your travel mission. In case you do not make it, you won't freeze because the heater will keep working (as long as you have enough 12V capacity).
In these freezing temperatures, I would also recommend to share the heat from the combustion heater with the main traction battery. It is essential to heat the battery early on to get the most of the benefit and perhaps even before you depart. It may not be necessary during the travel as the battery cools down rather slowly.

Hi Don,
It has been especially cold in New Jersey lately, and I recently took some battery temperature readings using Canion. I also keep my car in the garage, and the garage stays above freezing even when the outside temperature is well below freezing. What I have found is that discharging the cars battery (running the car) will increase the temperature of the cars battery even when the outside temperature is much colder. I started out and my battery was just a little warmer than the ambient temperature in my garage (a couple of degrees above freezing). Even though the outside temperature was a little over 0º F, the battery cell temperatures continued to rise a few degrees as I was driving.

I've seen that, too. If you want to heat the battery, get on the highway or pull some big hills, then hit the charger. I managed to get my battery to 70 F with 10 F ambient temperatures by 10 miles of 50 mph main roads, 20 miles of 65 MPH highway, followed by 3-4 hours of level 2, then the same on the way home. Motor coolant temp was also in the 80's after getting off the highway.

Regarding using the fuel heater for heating the battery, heat the battery early on, then let the nature of our cells carry on from there, keeping themselves warm. If you're somewhere secure, dump heat into the pack while charging.

Don's adventure with a zero degree Celsius cell still holding over 3.5V at 6% SOC just gives me more confidence in Mitsubishi's pack management. According to the mfr specs, 3.5V at zero degrees should be only about a 40 amp-hr discharge, and is still high on the knee (ie- hasn't yet fallen off the cliff)!

I have a question that I thought someone here might have an answer to.

Has anyone successfully installed or heard of some one who installed a diesel liquid heater
in a Leaf or Kia Soul,
or any other EV for that matter?
