The car is a week old, but from the VIN it looks like I have an NCM battery. Been keeping the charge between 20% and 80% mostly.
My window sticker says I have a 91KWH USABLE EXT BATTERY. What does your sticker say about the battery.
This is a UK thread and in the UK we don't have window stickers.
It is not always 91. It losses capacity with age, and mostly noticeable - with lower temperature. I charged my standard battery to 100% at 30F a couple days ago, and it only got 58 kwh. At 80F it was 66 kwh max.
I like to think of the guess-o-meter as a credit score. takes into account weather & road conditions, driving style, prep and auxiliary draws on the battery. Could it have been all the ‘stars’ (so-to-speak) were in alignment to cause such a noticeable drop?
I’m not sure this is true. I just charged over the weekend. The charger says I added 45.5kwh and my cars log states 50% added. This is would equal exactly 91kwh, the same as what the manufacturer claims as the usable battery any time I have checked this in the past it always works out as exactly 91kwh. The actual battery is 98kwh but they keep some of it unusable specifically to limit battery degradation. The temperature doesn’t affect the capacity, but it does affect its efficiency at both charging and powering the car. You will get less range but the usable capacity is the same. I would expect in a few years a difference may start to be noticeable, as the battery ages. Apparently the batteries should be good for 10 years till the capacity starts to become an issue with estimates being around 85-90% of capacity.
The data received from ODBII doesn't prove that - with lower battery temperature it shows a lower KWh number for 100%. It is also my understanding or the preconditioning of the battery - it get warmer and can hold a higher charge.
watch your climate temps, I forgot which update it was, it really uses power now on our 22 rwd stnd. we were happy until started updating, we take the chill out and shut it off, ac not so bad
It's because you're driving so slow, only about 25 MPH there. With full heat output, the most efficient driving speed is about 40 MPH. Slower than that, you burn through heat faster than you can rack up miles. In the summer, the most efficient speed is about 30 MPH due to lower energy use.and this is what I hit this morning driving to work, this is including preconditioning.
That is 0.9 miles per kWh meaning I would get less than 90 miles on a full charge if it continued at that rate.
I must have a faulty car as it is drastically different to what other people are experiencing
That’s great advice for driving around a city on my commute to work especially when it’s icy lol. I’ll make sure and explain to the cops that I was just driving efficiently when I get pulled over for speeding.
Same reason I averaged 11-13 mpg in my last car though. My commute to work was 30 mph zones and 1 mile from home. Half the time was spent in the parking lot.
