Hi, Im new here.

I dont know whats going on. I just got mine last weekend and I'm getting 1.7 mi/kwh. It had 10 miles on it when I got it and now it has 242 miles. I accelerate slowly and brake slowly like I did in my old prius. I've been experimenting with L mode and the "paddle" if I'm in D mode. My commute is only 25 miles so I pretty much only drive it 50 miles/day and charge it on the standard 120V charger. I live in the SF Bay Area and my commute to work averages about 50 mph and coming home is a lot lower in traffic. Can anyone help??? thanks!

Woah.. Huge difference. Why is the app so wrong? My dashboard says 3.6 mi/kwh. whew. thanks Matt!.
When I recharge, I reset the trip odometer and then it computes the mi/kWh as I go and you can check it just by looking down. I also record the miles traveled and kWh used before recharging, just because I did that for 48 years of ICE driving.

I charge to Hilltop Reserve for the battery's sake, not 'cause I'm on a hill, but I still reset the trip odometer to zero when starting out again. Correct me, gang, if I'm wrong, but I think the "Energy Information" considers charging to HR as "last full charge" and resets those parameters to zero.

:eek:I've had my Bolt for about six weeks, and I'll reach 1000 miles within the next several days. I'm trying to decide how I want to drive it. First, hill top reserve. I don't see the purpose. I'm going to utilize the Bolt's BIG battery to the max. When I charge, I'm going to fill it up. I live in a fairly flat area, so the lack of regen with a full battery isn't an issue with me. I love my Bolt and although it's a lease, I treat it like it's mine. The notion to use hill top reserve to save the battery for later isn't a concern. The Bolt is too new to suggest it's even an issue. My Prius Plug In and BMW i3 were always charged to the max, why should I treat my Bolt differently?

I'm averaging around 260 miles range on three full charges. I'd like to record at least one 300 mile charge, but is it worth it? I find that I drive my Bolt like I did with my Prius Plug In with 10 mile EV range, very conservatively. With a almost guaranteed 240 mile range, why should I? From now on, I'll drive for fun, or as conditions dictate, run the AC and heat when needed, and charge when required.

I totally agree with what you are saying. I have never had a hybrid or an EV. This is my first non-ICE vehicle. EV should be like this and the driver should not have to compromise. This is why I like the Bolt and is only jumping in at this time.

I think this issue has been resolved as a software issue - the actual car is getting the range/consumption expected - if that is the case may I humbly suggest the original poster update the title to select the actual problem - the head line is a bit sensational where as it turns out to be a reporting/software problem with GM's online services, not an actual problem with the car.

In hill top reserve setting, the Bolt considers that the last full charge and computes things from that point. I occasionally charge to full at a free charger at a theater parking lot. Sometimes, although it appears to be a full charge, the Bolt doesn't register it that way. If you keep track of kwhr used, then everything works out in the end.

Yes, the Bolt, especially when hilltop is used, always shows less than 238 mile range.

Yes, now that's it's winter, in hilltop, the Bolt always shows WAY less than 238 mile range, often 140 - 160 miles.

BTW, hilltop is not about saving the battery for the next owner, it's about having rengen always available for those of us who use "L" mode exclusively.

If it were a Leaf or an i3, that percentage drop in range would preclude using hilltop and induce range anxiety in even local use. As it's a Bolt, there's plenty of real world range for all our local use. In summer, it wasn't necessary to even consider having to plug in/ top off every day. In winter, we plug in just to be able to precondition.

Well that's all well and good, but charging a Lithium battery to 100% all the time makes your battery degrade more quickly. Until the technology changes, a lithium battery maintains it's capacity longer if you use the middle. For most products that 20-80%, for some batteries are best 10-80 some 20-90, but using either end degrades your battery more rapidly. This is why the Tesla has their equivalent of "Hilltop Reserve" on by default and you can only charge fully if you press an override.

If you don't care that you have more than 190mi range in 3 yrs, have at it and don't use HR. Myself, I live on a big hill so I use HR, but I would still use it if I lived in a valley and had to climb because I want my car to have >220mi range in 4yrs when I want it.

All cars have a compromise depending what you value in the car. But if you are driving less than 150mi each day what is the compromise with HR?

So while it may seem odd, I'm going to hit "revive" on this post to see if anyone else is seeing the same thing. I've posted separately about 'charging to full' issues, but this is EXACTLY a problem I'm CURRENTLY having (with the latest My Chevrolet app. (updated)).

1) My daily mi/Kwh is ALWAYS either 1.0 or 1.1, but I can go out and look at the car and it's 3.6-4.8 (range I've seen just in 2 weeks).
2) The app AND CAR will randomly show "fully charged, range of 425m" or other numbers well over 400. Then you get in the car and it shows the same thing, but once you start it the range will adjust down to the very low 200's.

I figured I'd need to update my app, but it is. This happens on BOTH the MyChevrolet apps we have installed in the family, but the fact that it shows the same on the car really confuses me. (didn't think to post this in my thread about the low range).

I have looked on here before and everything I see is a "this was fixed" somewhere in the end of the post. Well, not for me.

Anyone else seeing this?

I don't think I'm seeing your exact issues, but in my experience, the recent versions of the app have been a hot mess.

The app will show 2 efficiency numbers: since full charge, and lifetime.

The car will show one efficiency number: since the trip meter was reset.

Those 3 numbers are not necessarily related to each other.

The most reliable efficiency number is on the car, but it is not connected to lifetime efficiency nor to when you last had a full charge. I reset the trip meter when I have a "full" charge (whatever my target charge level is).

From the app, I really only use the SOC number (and maybe the tire pressure numbers). I ignore the efficiency numbers.

Also, see my response to your other post.
