Charging loss

[Erewegoagain]

I used to have the cheapest commute possible as on arrival at Cheshire Oaks after my 170 mile journey there were 2 Tesla destination chargers and I could fill my car for free.

Sadly all great things come to an end and today I arrived to see them replaced by ChargePoint chargers. I’m wondering if I therefore plan in a stop at Keele…..

which brings me to my question. If I charge with a supercharger I believe that is DC charging and there is little loss compared with a non Tesla charger. Can anyone tell me how much the loss is when converting AC to DC as the superchargers are slightly more per KW but I wonder if they aren’t dearer in reality

thanks

It doesn't matter at a SuC as Tesla bill you for kwh delivered to the car and not the AC consumed by the charger as other companies do

Based on the new chargers at Rugby, it was around 13%, based on the data from TeslaFi, compared to the charger itself.

Not looking good for Leavesden https://www.watfordobserver.co.uk/news/19512641.tesla-loses-second-application-unlawful-creation-charging-spaces/ I worked in Kings Langley and honestly I think this was not a good choice for a supercharger location. Fiddly access from the M25 with long queues...

The AC chargers bill you per kwh used, so some energy is wasted by the the car's onboard AC-DC charging system.
Anyway, I'd say if it bothers you, simply choose a charger that has the lowest £/kwh.
