My EV Driving ratio

My login screen data seems to be significantly wrong, 26MPGe .

Are you thinking that the "Energy Consumption" screen does not including charging losses?

 

Here are my screen shots



Been a rough month with multipel high-speed long trips bring me down.

I miss voltstat.. this format is not very useful.

 

Oct 1,323 1,367 1000+ MPG 1.36 gal
Sep 1,412 1,461 1000+ MPG 1.26 gal
Aug 1,547 1,820 215.68 MPG 8.44 gal
Jul 1,234 1,534 162.51 MPG 9.44 gal



I would like VoltStats to gather a bit more data than what he is getting through the RemoteLink interface. I'm not sure why he isn't using the MyVolt interface and getting things like charging history, and trips (mileage history).

He could get better MPGe and miles/kWh and kWh/100 miles for the fleet.

Using the ZIP code as well as charging date/time he could do a ghg calculation as well.

 

I occasionally take 100 mile out of town trips without the chance for an opportunity charge. Most daily trips are covered by overnight 120v charging but there are still a few more in the evening that a faster 240v charger could cover. Even so, I think I'm doing pretty good :

3400 miles, 800 gas, 76.5% EV
Lifetime mpg: 142
MPGe: 80 (must resist sport mode must...... resist.......)

 

Getting +45 mpg in gas hybrid mode on the Volt is very respectable. 3.5 miles per kwh charge is about what I've been reading is normal for a Volt - but you should get more if you hypermile and/ or keep your speed under 50 mph. The 240v charger is suppose to be more efficient ( less power loss during the rechargin process) than the 120v charger. On cleanmpg.com, one of the more experienced hypermilers reported getting an overall 7 mile per kwh on a Nissan Leaf ( cancelling out any elevation advantage because they are going back and forth along the same commute) - I would think that a Chevy Volt could do the same if the driver hypermiled it.

 

just about right.. (depends if you measure miles per kwh before or after charge.. both cars report after charge loss.
The top 4 "volt" trips on a 10.4kw charge battery are 71, 72.9, 75 and 82..
Though the last 2 have some elevations gains.

 

This is the best I've done. It was along a rural route with several elevation changes and stop signs. I chose it because it was safe to travel <45mph and not disrupt traffic.

 

I am not trying to knock the Volt in any way, but I thought it was kind of strange that they separate the electric mileage and the kWh used to get that mileage. The same thing is true for the gas mileage. I would have thought that they would have been able to come up with a more user friendly screen layout. It's just not intuitive at first as to how the 4 sets of numbers relate.

The nice thing is that it's all software driven so they can change it with an update.

 

61.2mi/10.3kwhr=5.94miles/kwh
12.6mi/.30gal=42mpg
The 246 and 142 divide miles driven by gas used (mpg). MPGe hadn't been adopted when the volt began production.

 

I get how to do the calculations, it's just that the numbers, for instance, the 61.2 mi and the corresponding 10.3 kWhr are separated. I would have thought that the 61.2 mi would have been directly above the 10.3 kWhr for easy reference. The same with the gas numbers. It's more of a formatting (screen layout) thing.

 

Here is what I'm talking about, with just a little cutting and pasting. It's a little more user friendly! Click image to view full size.

 

I prefer the current layout, especially the larger display of kWh used. Mileage on the left, fuel info on the right.

If anything I would like to be able to rotate between "This Trip", "This Charge", and "Lifetime" displays of the same information. There is a Trip A and Trip B odometer that could each have their own corresponding detail display as well.

When I first started driving the Volt I thought the instrumentation included some "personalization" in the sense that driving statistics could be maintained for different drivers which would be a nice feature for a vehicle with multiple drivers. My kids used to be a little competitive with the Prius, seeing who could get the best mpg.

 

It doesn't mean that the kWh text size can't change. But, doesn't it make more sense to have one on top of the other? It's just that you are used to the way it is. Guaranteed, any newcomer would be able to decipher the screen more easily with my layout.

 

Yes, I like your changes but.... one thing you might not be taking into consideration is distance. Most photos like mine of the display are closeups taken with a camera phone a few inches away. Viewed from the drivers seat, the sets of numbers appear much closer together and it's easier to put "1+1" together to make 2. Hope that makes sense.

 

I don't find the current display hard to decipher.

Your proposed layout clearly prompts a mental calculation of miles/kWh or miles/gallon, which is a driver distraction, imo.

There is another set of displays on MyVolt.com that complement the vehicle displays.
