New PiP Owners...More data please!!!

Trust me, I'm the world biggest leadfoot! That's exactly why I got the Pip, so I can get in that carpool lane and go for it. Yes, LA traffic truly is that bad. Enjoy your ride in NY. You're going to love the car.

 

Thanks.. I'm still confused by these displays.

Is the 18kw from the wall or battery?

Since the "today" line seems 51.6 to say 39mi 0G it seems to do some agressive rounding/truncation for display. If 51.6miles / 73mpg since it seems like .70 gallons used.


Forget NY.. try Colorado for a change of pace and getting out of the crowds..
Sunny and 70 yesterday

 

I assume 18kw is from the battery. I don't have a kill a watt to measure from the wall. It does round to whole numbers in that display.

 

Almost ready to fill up. Here's the latest stats.

Today: 55.4mi Cons. 109mpg Avg 24mph (charged at start and at work)
EV: 53% 29mi 5kwh HV: 47% 25mi 0G Fuel Saved: .4G

Lifetime: 577.1mi Cons. 71mpg Avg 25mph
EV: 26% 153mi 34kwh HV: 74% 423mi 8G Fuel Saved: 2.8G

I won't be using the car for the next 2 weeks. Can't wait to see what the next tank will average with charging at home and now at work.

 

Lurk,
Your 577 miles at 25 mph is amazing to believe.
And most of that is on a Highway ???

All non-EV/PHE vehicle owners should take the Bus !!!

 

Very nice!!

 

Impressive EV to HV ratio on your trip today. It will bump up your lifetime EV to HV ratio.

Your lifetime (so far) electric mile efficiency is 22.2 kWh/100mi and gasoline efficiency is 52.8 MPG.

 

Yeah, it really is highway. The 210 and 134 actually. I never realized how slow it really is. On the weekend the average speed on that highway is more like 80mph.

 

It was even better before I stopped at Lowe's. The 25.7 miles was 130mpg before the stop.

 

Prius PHV uses 85% when full to 23% when it switches to HV mode. That's 62% depth of discharge. It comes out to 2.73 kWh usable energy.

 

keep in mind, average speeds take all "On" time into consideration including when in park or sitting at lights.

we drove to Disneyland in 2010 in our Prius. it was set CC at 65 mph and drive. we stopped to pee, eat, etc. it was get off. park do our business, get back in and go...

did we average 65 mph?? nope. 60? nope..

50?? nope...

we averaged 44 mph on one tank, 47 mph on another. twice we got off the freeway and total distance driven was probably less than a mile. rest stops; even less than that.

so dont get thrown by the average speed over the entire tank...it means practically nothing.

if you want it to be real low. simply turn on the car then go sit in your living room for a few hours, then go back out and drive. do that every day and you wont average 10 mph for the tank

 

What is your source for this information? How authoritative is it? Is it from Toyota, measurements from the CAN bus, or is this your own calculated estimate based on the best information you can find so far?

 

If it's only 2.73 usable then why is the wall measurement that Tracksyde did 3.28 measured by kill-a-watt? Is there loss or something else i'm not getting?

 

That is well within the range of charger loss converting from wall curent, into the high voltage DC needed for the batteries and most is loss as heat during the charging process. (Feel a charging battery in a laptop and you can feel the "loss").

Decent chargers range from 80%o 90% efficient. 240v chargers are a tad more efficient. Overall efficiency also depends on on how fast the batteries absorb charge and if one needs to cool them or heat them while doing so. .273/3.28 is 83% efficient charging which is about the same as the Volt. I find dividing by 1.2 to be a good approximation for car to wall for most EVs.



Note when quoting wh/mi one should use Wall power, accounting for charger efficiency. (USBseawolf tends to ignore that loss for the Prius and then compare to EPA data for other cars which do include charger loss). The 29kw/100 miles on the EPA sticker is based on wall power, not what the car reports.

 

If I remember correctly, your lifetime includes one long trip in HV (picking-up the car with zero EV miles).
With your driving patterns I can see your lifetime utility factor (% EV) climbing to the high thirties in the future.

 

Tracksyde pulled it from CAN bus with the Torque app.

 

I am not sure yet. 2.73 kWh from the battery and 3.28 kWh from the wall. The car display rounds it to 3 kWh so the only way to tell is by keeping track of multiple charges enough to tell the difference.

 

The EPA process is well documented for other PHEVs so I cannot imaging they would do anything different for the prius PHV. EPA data for the Volt is based charging using 12.9kw, while the usable is 10.4kw.

Also what makes you think the Prius rounds? So far all display's data posted here that I've analysed suggests Prius truncates, not rounds.

 

It may appear to be truncated in one trip but may be included in the next trip. Until we have better tracking, we won't know for sure. That's why I like to focus on the lifetime number than the trip.
