Help - Mileage Sucks

For short trips without EV, that is indeed reasonable to expect. Go longer or warmed up with EV, the results are quite different... as is driving sometime other than winter.

 

Stupid question but "warmed up with EV" ???

 

warm up in hv then switch to ev. ice will cycle to provide heat and ev miles will increase your average mpg's. you have to be able to plug in tho.

 

It takes around 4 minutes to warm-up the system with temps in the 20's. During that time, the engine & emission system gets heated coolant circulated. The battery also receives some charge from excess energy caused by the running the engine at a controlled rate, while also drawing some electricity. All that is considering warming. When done, you've got EV available, even with the heater on. That's when you start seeing 100 MPG segments on the consumption screen.

For my morning commute, there is often just 3 minutes of MPG segments followed by most pegged at 100. So, it really depends on the circumstances. On one of the really warm days of summer, I made it all the way to work (17 miles) without the engine ever starting. No chance of that happening in the winter.

 

That mean I have to switch only on EV not EV and ECO together ,SORRY but I don't know to much for hybrid and probably for someone this is stupid questions .

 

EV and ECO together is fine. Are you saying you're getting 38 mpg in EV ECO mode?

 

Really? If we can't agree on facts, then we're not going to get anywhere. Then again, I disagreed with most of the suggestions on this thread. So what do I know? Good luck. Be sure to take pics.

 

It shows you went 8 miles with 2 kWh of electricity. There is about 2.7 kWh usable in the battery so you did not use it completely. Calculation shows you still had ~2.8 EV miles left.

Can you take a pic of the summary screen after turning off the car, tomorrow?

 

Does the display round off the figures to zero decimal point? I can't recall seeing 2.7 or 2.8 kWh used on my display. I think it will show either 2 or 3 kWh just like it does with the gal used figure. I recall looking at my display once with a completely exhausted EV batt (where I started off with a full charge) and it only showed 2kWh used not 2.7 or 2.8 kWh.

 

Hello Gary, How did you go about resetting your EV/HV Ratio ?

 

I think you are right. The display truncates to a full number.

Assuming all the battery charge was used up, we can break down the consumption:

22 miles / 58 MPG = 0.38 gallon used for the trip. Since only 14 miles miles ran on gas, 14 miles / 0.38 gallon = 36.9 MPG on gas.

Plus 8 EV miles on 3.1 kWh means 388 Wh/mi (with charging loss) on electricity. Those are high consumption numbers for both electricity and gasoline. For your reference, I am averaging 264 Wh/mi on electricity and 55 MPG on gas.

At this point, we should focus on the driving condition, speed and the trip duration (mins). It may turn out to be the car (alignment or brake stuck?, etc..).

 

58 mpg was on the outbound commute. does that correlate to the 22 miles?

 

Hello Gary, I believe that the only way that one can reset the Ratio is by rebooting, that is by disconnecting the 12V battery for a few seconds. All you did was to reset the A and B trip indicators. I may be wrong on this, if so somebody will correct me.

 

Yes, if it was 3 EV miles.

That also mean the return trip got 5 EV miles because the total said 8 EV miles.

The only way to know for sure is to look at that EV mile counter on the EV Driving Ratio screen before and after.

What's the reason why your wife cannot use more EV miles? Is it because,

1) She turns on the heater?
2) Very hilly road?
3) Manually switch to HV mode?

11 miles one way trip could be covered with pure EV even at highway speed (50-55mph).
