My estimated range has been shrinking. Back in 2018 I was getting estimates of 15-18 miles (although I never achieved that); more recently I was getting 13 and now I am down to 10-11 mile estimates. And the most recent shrinking (no George Constanza jokes please) happened as the outside temperature has declined from the low 100s to the 70s and 80s when I would have expected it to rise.

I checked my app and I am putting at most 6 KWH into my battery when charging. What are others getting?

Thanks.

Very curious here as well. Lower temperatures (~70F) should be the most ideal conditions for the battery and I’m seeing my range increase as a result of the drop in temperatures here in Philly.

I know my MY2020 has the slightly larger battery, but this is a picture I took on Friday after a drive from a full battery to flat. I don’t hyper mile so I keep my climate control on, but I did use ECO Pro. In 100F that would have been between 12 and 15.

I am also curious as to what others are seeing.

I have the larger 2020 battery and my range has been consistent with my driving patterns and outside temps. Last week, I signed up with "Recurrent Auto". They monitor my battery health through a connection thru my "connected drive" and will send me a monthly report on battery condition. First one due in Dec. Their stated goal is to develop an industry-wide baseline of battery condition. They also advise that their battery condition reports should help with resale, when the time comes.

I will give that a shot since it worked for you. I tried previously, but the site kept saying I didn't have a supported car and support never got back to me.

Guess I am still out of luck for that service. Let me know how it goes!

Batteries like higher temps not too low or lower. This is caused by lower resistance when warmer.

You only see lower mileages in summer due aircon not a less efficient battery.

I have a solar plant in my home and the batter lives next door to my boiler to keep it warm all year round.

Seems counter intuitive.

The 530e will keep the battery in a safe operating range. If you are in cold temps (under 50F or so) or high temps (above 80F or so) the car will. Heat or cool the battery as needed to keep it in that range.

Even if you skip climate control you will lose range due to this.

Hi logical

I thought the 530e didn't actually do this and preconditioning is actually only for the cabin yet if started early enough (hour plus)it has the side effect of heating the battery but it's not actually designed for that.

Think I saw a few articles on this also online.

You're right that preconditioning with a scheduled time in the future (I believe at least 3 hours or so, but possibly as low as 40 minutes) will do this before you start the drive. If you fail to do this before starting the drive the car will do this first using the ICE and will let you know the HV battery is outside of operating range and will be heated or cooled until it is and become usable after it has.

It will also heat or cool the battery while driving if the temperature gets too high or too low as well.

These can slightly reduce range.

curious--accepted me first try 2020 530e.

I had my car in for maintenance yesterday. I explained to my SA about the charging issue. She called me in the afternoon and said that the software update should help with the estimate issue; I explained, again, that what concerned me was not the estimate but the amount of energy I was putting into the battery according to the BMW App. 5-6 KWH instead of 7 or 7.5.

She just called me to say that everything was done except they ran a test on the battery and one cell came back bad. They ran it again and sent it off to BMW corporate and now I wait to hear back.

The lesson, to me, is to focus on the amount of energy going into the battery and not the battery estimate (which is too controlled by external factors like driving style, weather, terrain, etc.

That's really good to know. I'll definitely keep an eye on how much the battery is taking in as it ages.

Interesting Steve keep us updated. Looks like you will be getting a new cell at a minimum under the warranty.

How are you determine this how much goes into the car? I just use my 110v charger overnight

The MyBMW app now reports charging information.

I saw on the X5 forum that in Europe they use more of the battery than we do in the US (referring to the 20% holdback here) but also have a shorter warranty. Looks like BMW is trying very hard NOT to use the battery warranty.

I shall report back.

[CnSky]

Have had charge reporting for a while in Europe see mine below.

What's the total battery size in a pre LCI should I be concerned max I get is 8kw.. should it be 9.3 when empty.

Or is it holding back 20% and only ever needing 8kw to charge remainder.

Hard to know.

I got 10kw a few weeks ago in a single charge session but used precondition.

My understanding is that i9n the US BMW holds back 20% to save the battery life. So on a 9.3 KWH battery, that means that 7.4 KWH should constitute a full charge (approximately; sometimes one cuts into that 20% so the actual battery capacity for a charge could be a tad higher). But I believe that in Europe the holdback is less (as is the battery warranty...duh!).

[CnSky]

Thanks Steve I think it's the same in Europe regards holdback but we still get a crap warranty, that's situation more or less standard over here regards all consumer products.

You guys is the US should be praising the TSB program it's unheard of over there for governments to protect the consumer.

I have actually used TSBs to get assistance from BMW CS before as it's so obvious they treat the east side of the Atlantic worse than the West.

They always cave when legally threatened for fear it spawns a similar system in the EU.

Anyone know how that saves battery life? I ask because from what I understand is that on the i3 it is the same however you can easily code it to use that 20% to maximize range as that car desperately needs.

If so are we able the code the 530e battery?

My SA called me late yesterday afternoon (a Friday). She said that BMW ordered them to remove the battery pack and run some more tests and she will get back to me sometime on Monday.

I do have a loaner (a stripped 330i) so I can get around but I do miss the little things on my 530e (soft closing doors; nappa leather; autohold; adaptive dampers; ACC; HUD; etc.).

The other matter I have noticed, and noticed previously on various loaners, is how much rougher the engine is without the electric motor to smooth it out.

[SteveinArizona]

Just heard back from my SA. They are going to replace the entire battery pack (all 6 cell packs). But they don't have them in stock so she said it will be a week or two.

[CnSky]

If they are using the new LCI battery then happy days Steve!!
