http://www.amazon.ca/P3-International-P4400-Kill-Monitor/dp/B00009MDBU254$........... I was looking for something below 20$, once i get data after a week I will probably get enough data maybe I will repeat this summer then...
I saw my volt stats, but i was not sure if this take in account all the electricity.Like Loboc said, I just log into myvolt.com and download the data from there. It measures actual power pulled from the wall, not the power stored to the battery. This means there is no need to apply efficiency corrections or otherwise manipulate the data. It's already accurate. The only downside is that it does batch uploads from the car to the Onstar servers once per day so you can't get real-time data. That's not really a big deal to me. Once I have the CSV file downloaded, I use Excel to crunch it into graphical form for trend analysis. This requires a bit of custom programming work to get daily summaries because the data comes in with a new line for every time you plug in the cord which could mean as many as 6 lines of data per day for me.
Hmmm.... Interesting question. I've never gone 2 days without using my car so I can't rightly say. I just downloaded my most recent record and looked for a day of non-use and couldn't find one. I also discovered that when you download the last 12 months worth, it just gives monthly totals. This means that you need to download and save the CSV file on a regular basis or you will lose the fine-grained details that are more than a month old.I saw my volt stats, but i was not sure if this take in account all the electricity.
So if I understand right.......if the car is plug for a week but not use, i should have 5 lines from My volts stats? This should give me how much KwH is being use to maintain the car.
PLEASE BE CAREFUL! Use caution with these Kill-A-Watt units. If you search this forum for Kill-A-Watt... You will find photos of a Volt owners who tried this device and it MELTED. (More than one.)http://www.amazon.ca/P3-International-P4400-Kill-Monitor/dp/B00009MDBU
There is this but I don't know how long I would run a 12a charge through it. Also it won't do a level 2 charge. Which is why I suggested the first one.
You are lucky... I have seen more than one MELTED Kill-A-Watt photos on this forum posted by other Volt owners. I would never leave one plugged in overnight. (Unless I was there to monitor it's temperature.) It's just not safe. I don't think the quality of the receptacle & current shunt are of sufficient quality to supply 12 amps for 12 hours a night without significant heat build up. You might have been lucky so far...I've been running 12A through it (Kill-a-watt) since 2011 and never had a problem.
It's just a photo showing a typical example of what CAN happen if you overload ANY outlet. Not specifically a Volt incident. If you want to see a specific photo of an outlet melted by a Volt EVSE you can see one in this excellent & helpful FAQ page posted by a moderator of this Forum:I note the date on the photo above is 2006, obviously before any Volt was sold or produced. (Just trying to avoid alarming anyone...)
