No Reading on Tire Pressure on 2012 Chevy Volt
May 29, 2014 at 9:11am ET
Then how far can a Chevy Volt get one ane charge? I plan to find out. Equipment used: one 2012 Chevy Volt with 52,000 EV miles and a whole lot of spare time!
FedEx Field Was The Perfect Base OF Operations
Let'south discuss what one charge means. In that location are three ways to charge a Chevy Volt: plugging in via J1772 connector, using Mountain Way, or reclaiming electricity via regenerative braking.
I've seen ranges as high as 141 miles using regenerative braking through large pinnacle changes. Theoretically, hundreds of miles tin can exist accomplished on one accuse via regenerative braking. I will exist using none of these methods to accuse the battery after my initial charge.
To achieve a very long range, 1 must almost never stop, in essence a test track should be used, or a road every bit much like a test runway as possible. I practise not take a exam rails to apply, so I had to locate a public road very much like a test track. A long land route would work, simply last fourth dimension I checked no such road exists well-nigh metro Washington DC.
The best choice in my example would exist a large traffic circle. In add-on, at that place needs to be nearby access to a level 2 charger. I succeeded in finding the perfect location, FedEx Field, home of the Washington Redskins. Surrounding FedEx Field is a giant traffic circle, and correct next to the road are 12 free solar powered level 2 chargers compliments of NRG eVgo.
The central factors affecting range are speed (lower the better), ambient temperature, tire PSI, driving style, elevation change, and climate control. I will exist driving effectually 20 MPH. Optimal temperature for efficiency is around the mid 80's Fahrenheit, which is warm, but not hot enough to engage thermal management of the bombardment. I volition exist using no climate control, of grade. Recommended tire pressure level by GM is 38 PSI. Really too low, many owners become with 42-45 PSI. A few hyper milers (me included) go with 50 PSI. For this test, I went way beyond that and set my tires to 60 PSI. Do non try this at domicile! Another factor in my favor is that my tires are pretty worn as they have 52,000 miles on them. Newer tires with more than tread create more friction with the road, reducing EV range and MPG.
Getting Underway!
I picked Memorial Twenty-four hour period for my run. It was a squeamish warm day, upper 80s Fahrenheit and I could spare a adept chunk of my mean solar day for this "exercise". Early afternoon I set out for FedEx Field. I used around 60% of battery to get to FedEx Field from Northern Virginia. About 2 1/4 hours later I had a full charge. However, I waited. I allow the battery rest for 30 minutes, and then turned on the Volt while it was still plugged in. This allows the Volt to charge an additional buffer. I will not go into details here, subject for some other commodity. Almost 10 minutes afterward, the battery was charged to the maximum allowed. This raised the actual state of charge from 87% to 89%. The Volt only allows 65% of the bombardment to be used, this trick bought me some other ii%.
A cardinal metric for measuring efficiency of how one drives is miles per kWh. My 2012 Volt has an EPA rated range of 35 miles on 10.0 kWh, or 3.five miles / kWh. Really efficient driving is 5 miles / kWh. This drive will go way across that.
At 6:25pm I started my run. I turned off my daytime running lights and made sure Bluetooth was off on my telephone. I did non want whatsoever precious electrons wasted on a Bluetooth connection. I had both front windows croaky almost i.5 inches due to the heat. There are a few small little hills on the ring road around FedEx Field. When going downward these hills, I use neutral to coast as much as possible. My speed varied from xix MPH up to equally high equally 25 MPH. Average speed for the entire run was 23 MPH. I really could not become slower since it was an agile road. By the time I finished and my range had dropped to 0 miles, I had driven 81.8 miles using 9.8 kWh for a measurement of viii.35 miles / kWh.
81.8 Miles On Electricity!
Hither is a table with my progress:

The drive required a lot of concentration keeping the speed at the perfect spot and continually shifting from bulldoze to neutral back to drive. It'south amazing how quickly the time actually passed. I did accept to stop once. I managed to take hold of the interest of a police officer who wanted to know what I was doing. I explained I was testing the electrical range on my Volt and he allow me on my style, or on my circle!
Unfortunately, I should accept started a little before. I had to plough on my lights dropping my efficiency from 8.v kWh. A 2014 Volt with around 11.0 kWh available has a decent adventure of getting to ninety EV miles on ane charge. Anyone with a 2014 Volt want to try???
