Hi all,

Firstly, I hope this is not something already discussed but I’m asking for some advice before I contact my service provider.

I took custody of my lease V1 58kWh a month ago (Dec 22) in the UK and have managed to put 2400miles onto it in temperatures between -5 and 15c. Since having the car I’ve found myself using a combination of home charging and public fast chargers. I’ve used a variety of fast chargers (150kW) including BP Pulse/IONITY and GridServe and have not managed to see the car achieve anything above 35kW charge speeds in all temperatures. It seems to stay at 30kW regardless of the charger speed. Additionally, I’m really struggling to get the cars economy above 3.0kWh despite normal road speeds with a keen eye on the economy - ie. SLOW.

Whilst I understand it’s winter and temperature affects performance/economy, I can’t help feel I should be seeing better performance figures and quicker charging speeds?

Any advice or suggestion will be appreciated.

Charging rates are a mixed bag when out and about on rapid chargers. Just because a charger is rated at 150kW or 350kW - the supply to that charger might not make that possible, or the kW output is based at 800v, and the Born is only rated to accept charge at whatever (assuming 250 or 400v, not sure what it is). Rapid charging also has a preference for a warm and quite empty battery.

Some chargers are faster than others in reality, despite what they are rated at.

Last week I did a 500 mile round trip, 170 miles on my own home charging, then a top up at a 175kW "charge point" charger. The car's battery was warm from the motorway driving - car pulled 41kW peak and in the 30s on average.

Next charge was done on an Ionity 350kW charger- 51kW peak and 42kW average.

Last charge was on a new 150kW rated Gridserve charger (part of an array of 8 new units at Moto Wetherby) - peak 81kW and ave 62kW charging speeds. The crappy old Gridserves on the same site gave me 29kW last time I used them!

In my experience, Osprey chargers are the quickest (I've had a 116kW peak charge rate).

When I jump on a 50kW charger, I usually get very close to 50kW for the whole charge.

On that very same round trip, temp was 5.5C when I left Newcastle and 7C when I arrived at Bedford. I drove all the way down with no heating except the steering wheel on 1, and got 3.2 miles per kWh for the journey. If I'd set the heating at 16C, my expectations would have been about 2.9kWh for the same journey, religiously sticking to 71mph, with no congestion to slow me down.

In the Summer, same journey, with some aircon on to cool things down would be an easy 3.8 miles per kWh.

Don't underestimate how much car heating can hammer efficiency, especially on shorter Winter journeys.

Hi Monkeyhanger,

Many thanks for your time and response.

It’s interesting to hear how many variables we have to deal with regarding temperature, car options and public chargers. Maybe I’m being naive generally and relying on the facts as opposed to being flexible with reality. Time for me to “tweak” to that nice balance.

Once again, thankyou!

OMG! am really not enjoying my Cupra Born anymore. Its been ok/ish for short local journeys, but since taking delivery of it in March this year, its already been recalled for tyre issues and also the main console was really glitchy and the reversing cameras just stopped working!
But yesterday, i think I really lost the will to live after it took me 9hours round trip to Birmingham from London...and there was literally no traffic!

I started in London - the car was charging overnight, but only managed to charge up to 80% - i checked my charging options, and it was set to charge to 100% so no idea what happened there. But it had 152 miles on the dashboard which, considering I only needed to drive 99miles, I thought i would be ok! but with around 32miles to go the car was down to only 4% and i had to find a service station to charge it!
At Frankley services I tried to plug into the Gridserve charger which was meant to be 50KW charger, each time i plugged in the cable, it said 'trying to connect' then disconnected...i tried it 4 times! i unhooked and plugged in again...but still said there was an issue!
I moved to the slow 7kw charger just to get some charge on it so i could drive to another place - at a cost of £14.60. Another car drove up, plugged into the Gridserve 50KW charger and it worked fine for him! I had to wait 1 and half hours to get enough charge to get me to the next charging station. I also tried the Gridserve one again after the other driver left, but still the same error!

I then drove to a BP Pulse charger further down the road - there were two 150KW charging points...after waiting an hour to get onto one of them..i plugged in and it went from 100KW to 20KW then 13KW...! It literally took 2 and half hours to get to 151miles on the car. I even swapped chargers as some other guy plugged into the one next to mine and he was getting i moved to his one after he left and the same thing happened! I was getting no more than 20KW...Because I'd swapped chargers and with BP you have to have at least £5 credit...this cost me £50! Ok so i have £8 in credit on my BP app....but the trip in total cost me nearly £60 and 9 hours of my life! To put that into perspective our other car is petrol...full tank costs £75 and we'd have gone there and back in 4to5 hours!

Our journey back was 95miles and we had 151 miles on the car...we barely made it back again...with 2% left on the battery..we'd had no heater on or radio as I couldn't face another charging situation! Why does the battery deplete so quickly on this car!

I was a total ambassador for EVs but maybe its just the CUPRA? I've never been so stressed on a long journey!

Its now going back to the garage for testing again next week...clearly there is an issue, but i notice on this thread that others have experienced similar situation..

Something really doesn't sound right with your car. I drive mine with little in mind about efficiency and get to 3.0 to 3.2M/KWh on a 160-180 Mile regular trip I do - aircon on at 21c, music blaring, cruising at approx 78 - 80mph, 90% of the journey on motorway driving, 2 of us in the car, sat nav on, ACC engaged. When I plug in (usually to a 350KW charger) I am getting the full 150-170KW reported on the charger between 20% and 80% with a gradual decline in speed as it fills that last 20% up to the 100% mark.

There is a know issue with some cars on the HV battery - might be worth seeking a dealership that can test it for you as it sounds incapable of holding charge and accepting charge under loads.

There must be something wrong with the car unless you had the cabin temperature at 30c and were doing 100 mph with 4 passengers driving into a headwind.

Now the weather has gotten a bit cooler I’m getting about 90 miles from 60% battery at worst. Don’t think I’ve ever seen it charge at less than 40kW on a rapid charger. Sounds like you have a battery fault.
