"Slow charge" option in My Cupra app

[mluisbrown]

Does anyone know if the "Slow charge" option really optimises battery life? I switched it on via the My Cupra app, and I couldn't find the equivalent option in e-Manager in the car. I have an 11kW charger at home and it seems to reduce charging rate from around 10kW to about 5kW.

I'm sure it does. There are various degrees of optimising from minimising rapid charging, DC charging in general, AC charging with the onboard charger unit is better for the battery than DC charging. So how far do you need to take optimising. If you have an 11kW charger reducing that to 5kW will be a further degree of optimising.
I'm sure not accelerating hard, avoiding very cold running or not driving hard would also be optimising measures but to what degree battery degradation is reduced is difficult to pin down.
I would think the difference in degradation charging at 5kW V 11kW is marginal.

The slow charge option on the Cupra gives me a 7mph charge, similar to a granny charger. Rarely useable if you want to keep charge sessions within a cheap tariff window of 4 or 5 hours. With the ID3 that option gave more like 12 mph which was more useful.

Is this option in the app, the same as the option in eManager to "Reduce charging power in alternating current" ?

I believe so. All it actually seems to do is half whatever charge rate a AC charge point can supply. Seems pretty stupid to me. Would actually make more sense if it worked on DC charging. 100 kW would wear out the battery far more than 50 kW.
