Left -25C, highway fast / stop & go, -24C at destination, some medium/strong wind. Cabin heater was set to comfort, 23C
Damn, I burned 0,88L gas for my morning commute and still have some kWh remaining in the battery, the ICE came on due to the infamous ERDT (even more this evening)
ERDT: Engine Run Due to Temperature, set at the lower position: -10C
I understand the ERDT having done a lot of reading on the Volt. I find it quite intriguing. I thought the ERDT would be on more that cold.
So, your opinion: Here today, -17C, my average day as for driving, maybe even more than average as I went out twice. A grand total of 6 km. (Yes, seriously.) Unless I have an appt., etc of the wife wants to go shopping and I have to travel to another town (small village here, 2 km and you've left it.) this is my average daily driving.
My question is, do you think the 6 km in town with pre-heat (Does the pre-heat work on 110?)) would be mostly EV? From what you said above, I'm thinking it would be.
Sorry, I missed your question here.
The Volt can be remotely preheat one or twice 10 minutes cycle a) unplug b) plug on 120V or c) 240V. If plugged b) or c) during and after preheat cycles, it can recover partially or totally the energy used to preheat the cabin, depends of the rest time after preheat cycles ended.
Below -10C (if set to very cold parameter) the ICE is programmed to start (notice: only once unplugged from the wall) to heat the liquid loop of the cabin heater. Once it reaches its temp. set point, then the ICE goes off (and on) based on the cabin loop temperature but if as soon the outside temp goes above -10C, then it will goes electric heat loop only...
The ERDT can be a bit annoying sometime with a MY2013+ when you still have plenty of remaining kWh (energy) available in the HV traction battery but that the way it is... In brief, in you do multiple errands (start & stop) and outside is -10C and below, you notice the ICE turn on/off without any driver control over that on/off cycling...
*2011-12, the ICE came in once if you don't turn the car off, it was possible to set climate control in Comfort, let say 23C and low speed fan (1 or 2), the electric heater keeps the cabin warm & cozy unless the heater loop temp. drops below ICE threshold temperature. Otherwise then, the ICE kicks on.
