80% of full charge is 228 miles?

[ChasingCoral]

So I’ve read that a fully charged CA Rte-1 MME should be around 310 miles. I have my charger set to charge to 80% but I’ve noticed it stops at about 228 miles. If 310 is truly the amount of a 100% charge this math doesn’t add up. Should I charge to 100% to see what the top end truly is and adjust accordingly or just increase my charge to a higher amount?

Your car charges to approximately 91 kWh of capacity. Your software will compare the actual charge against what your car is capable of reaching (taking any capacity deterioration into consideration). When charged as far as it will go, it will deem that to be 100%. If it measures you have reached approximately 72.8 kWh it will deem that to be 80%. (nb: it doesn't actually measure kWh, it measures voltage and current but that's another matter and clearly farther in the weeds than you are ready for.)

There's a reason why it's called a Guess-o-meter, everything is fine, just enjoy your car. How often do you travel 310 miles in a day?

I think the worry is how many miles will a person get when they are on a longer trip. Until the EV charging network is built out it is something to worry about. Once a person gets some experience at it then becomes easier.

I disagree, but ok

Just charge it and go, the GOM is only because you are light/heavy footed and whatever the temps are... The Mrs. drives like stepping on an eggshell and mostly city, I drive the highway 68-72.

I think you should take it in for service. I heard they were putting in the wrong size packs last winter.

These cars were tested in the most perfect conditions possible, which is very misleading for the consumer. I wish we had a standard where we would drive the cars in very cold weather, on an uphill at highway speeds to get their true range.

Mileage is a moving target with EV's, at least with the MME. I'm usually closer to about 200 miles at 80 percent, but the only time that really happens is on the road.
I fully charge Sir Barton each day in the garage at the end of its local travels. Traveling locally, the screen indicates as much as 291 miles. Once I plug in a long-distance destination, however, that estimate drops siginificantly as I pull from the driveway -- based on assumptions made regarding how fast I will travel on interstates and what level of climbing the journey will present. Once I stop to recharge on the road, I usually get between 180 and 210 miles at 80 percent charge. Somone on here smarter than I accurately termed the odometer as a "guess-ometer." I do know that when I use Blue Cruise and travel at or slightly above the posted limit that our MME actually banks estimated mileage as we travel. I love our MME; best vehicle I've ever owned. But travel and range projections are tiresome at best. I hope this helps.

Range is a moving target with every vehicle ever made. It just isn't obsessed over with gasoline ICE vehicles. I bet there's even more focus on range on hydrogen powered vehicle forums. Talk about lack of infrastructure...

We've only had our MME for a few months. We've seen range as high as 350 miles when traveling 45-50mph on long flat roads, to as low as 200 miles when driving 75-80 mph with a slight headwind and slight incline.

 

[tuminatr]

Yeah, I'm getting ready to switch to the Continental DWS06 myself.

That's a really good all-season but not a great winter tire. I would suggest an all-weather that is going to be much better in the cold, even cold and wet. think Cross Climate, Quatrac Pro, Pirelli Weatheractive

 

[Graybeard]

Also it helps to reset the GOM in the settings every season. What you are seeing is basically an average based on your driving habits.

There is a standard. It's the EPA range. Your suggestion would not be very helpful for people driving in California, or Florida, or Arizona. And it would create all sorts of confusion in the summer.

What we need here are more informed drivers. Do you know how many people don't agree that in winter a gas vehicle gets lower mpg due to winter gas and cold temps?

You are correct it's about a 17% drop. The other thing that most people don't know is the air is more dense so ICE cars make more horsepower.

The EPA measures in the most perfect conditions. Even if you live in the summer, stress testing the vehicle lets you only what is the minimum amount of range you can receive, no matter your situation.

Even though gas cars perform worse in the winter, they are still champions in the range department, and EVs have the worst hit in the cold.

I'll disagree with your conclusion, and leave it at that.
