Is a 75% range lose during winter normal

[DanielB]

Hey, the last month and a half I have been struggling with the capacity of my battery. I have the 77kwh battery in my born. But when I charge my car from 20%-80% it only puts about 16-18kwh of power on the battery, where I would normally be closer to 50kwh.
Also keeping the battery between 80 and 20% I only get about 62km of range.
I tried contacting my dealer about this. But they told me it was just due to the temperature outside, even though it's currently between 3 and 8 degrees celsius outside.
The car is a 2023 model and has 24.000km on it, is this normal? Because I have never had this issue last winter, even though it got alot colder.

Hi - No that's not right at all. You should get at least 200km on 60% of total battery capacity assuming a winter-low efficiency of, say, 4.5km/kwh. I use miles and miles/kwh as I'm in the UK. But my 58kwk Born V2 gets a good 100miles for 60% of my battery even when cold (which here is generally above freezing). I usually get 2.8 or 2.9miles/kwh winter and 3.8-4.5 in the summer. The heat pump in mine uses far less battery than standard air-con. Obviously it varies depending on where you're driving and at what speed. Looks like you have a major battery issue if you're only getting 62km.

Your car/battery is defect, go to the dealer, or find another one.

The worst I can manage driving in -10 deg c on motorway using 60% capacity would be about 160km but typically closer to 200km

Summer local driving 15kw/100km - winter 20-23
Summer Autobahn 20 - winter 25-28

Those numbers are when driving normal, ie not trying to be particularly efficient.

As said this doesn’t sound right. My home charger charges the same % currently in the cold as it does in normal temps. Charged to 80%, showed 270km range (58kw) today and drove about 15km or so with heater etc full blast and used less than 10% and it’s about -4 here.

We have a 77kw Born and at 2 degrees Centigrade and we charged 34 kw on a DC charger no problem.

Thanks you all for the help. I have reached out to the dealership again and they agreed to take. Look at it this time, unfortunately not before 3rd of February though.

I have found that range loss in winter is caused by having to use the heater to keep windows clear as no fan only option. Opening the windows works but then the car gets cold quickly. Recent trip of mainly motorway, 145 miles, I was down to under 30miles from 100% battery on 58kwh. I think if there was a fan only option I wouldn’t have needed the heater as much. I was only using the heater at times to conserve battery so think I would have dropped a lot more if constantly used.

Having to use the heater is one factor, but by far the main factor is the effect of the cold temperature on the batteries performance.
