I drive a 65 mph streatch for 3 miles twice every day. Which is better to do? a. Leave the PIP in EV and let it auto-switch to HV above 62 mph and auto-switch back to EV when I leave the highway. b. While on the ramp manually select HV, drive the highway, then manually select EV when leaving the highway. c. While still on lower speed road, manually select HV, so ICE starts warming up before the highway, drive the highway, then manually select EV when leaving the highway. A. will use more Battery, but less gas and raise mpg. B. & C. may save Battery, but use more gas and lower mpg.
imho B is better than C, what's the point of warming up the engine at lower speeds? but I think A is the way to go. don't try to outsmart the car.
Does it actually auto switch? I have never seen EV mode automatically turn off before. It stays on no matter what speed I am driving.
You left out the most important part we need to answer this question. How many miles is your commute and do you charge at work? If you have a short commute and you charge at work then leave it in EV and drive below 62mph. If you don't have enough charge to drive the entire trip in EV then consider driving in regular HV mode on the freeway and hypermiling the remaining distance to work until you get a feel for the areas in which EV use is best. I.e. could you cover some areas with regular hypermiling techniques and therefor save charge for the more demanding areas?
How long is your trip? Honestly I would stay under 100 km/h and stay in EV if it was me, for that short of a distance. Seems like running the ICE for 3 miles is a little wasteful
Yes if you have a short trip and you can make it in all EV then thats a no brainer. Leave it in EV and keep it under 62 mph. I assume thats not a possibility and thats why you are asking the question. What I find works best is if I activate hv about a mile before I know I will need it to give the ICE time to warm up. If the ICE has already been warmed up that day then I will activate it a little later, just as Im about to go up to speed. If you activate ICE as your going up the hill or on the onramp you use a lot more EV power. I have found that I use just as much EV power as I would without the ICE if I wait too long to activate HV.
If you are in EV and your speed increases above 62 the ICE will start and the EV symbol will go out. It uses battery while the ICE is warming up and then uses both Battery & ICE to power the PIP. If you switch to HV, the PIP remembers the Battery miles capacity state and recovers the Battery mile capacity after the ICE has warmed up.
My normal commute is 14.6 miles, including the 3 highway miles of 65 mph. When I leave the house with a full charge, I usually see 12.6 miles with the fan and heater off. I turn on the AC and the miles drop to 11.6. If I leave the PIP in EV, I run out of battery 2-3 miles before getting to work. If I manually switch to HV for the highway and back to EV after the 3 miles, I can Almost get work. I'll try to document the Trip A and EV1 numbers for the 3 scenarios.
Maybe you could try using EV Mode until you hit the highway. Then go into HV Mode and hyper mile the rest of the way to work. On the way home you could use EV Mode until the freeway then hypermile the rest of the way home?
That's why I posted the Question: Which is better to do? A. B. or C. And I don't just want an Answer. I want Proof why your Answer is better that the others. I do use EV when not on the highway, until the battery runs out.
Exactly, I dont think anyone is going to put together a spreadsheet for your "Proof". All we are going to give you is our opinions based on our own travels. I assume you work 5 days a week. Starting next Monday, go a whole week using #1. Tally your data on Saturday. Week two, use #2, tally your data. Week three, you get the idea.... Then report back to us and give US, YOUR Answer...
Looks like you are close to getting all EV. I would try B first. Try to P&G, get up to 65 and glide for as long as you can down to 60. Try to stay at or below 62 for as long as you can. Is there a way to skip the 3 miles of highway? But, as others said you will have to experiment and see what is best. Look at adding grill blocking.
For the love of god and respect to other drivers on the road, please never do this. Just don't go on the highway. I have enough people attempting to merge at 40 mph as is.
That is why I said try and also asked if he could skip the highway. Also, going 5 under the maximum speed is not that bad.
In either the San Franciso Bay area or the L.A. area, going 5mph over the speed limit when traffic would permit going faster is to subject oneself to nasty road rage (or at least middle-finger salutes).
Not everyone lives in the bay area. OP will have to see how his conditions are. With only 3 miles and going 65 he will be on the highway for less than 3 minutes. He may not have time to leave the right lane.
