Electricity doesn't magically disappear, 50kW chargers very reliably deliver 50kW to your battery. Reality won't deviate from the theory by more than a few percent.
No! It delivers 50kW continuously! It’s an hour to deliver 50kWh. Or, likely, slightly longer because of (minimal) losses.
Depending on the SoC, battery temp etc. But yeah basically.
I was more commenting on the kW vs KWh.
The reality, in my experience, is that charger output varies. A 50 kw charger locally generally only puts out about 35 kw. That's been with various SOCs. Also had similar experience at a local Ionity charger....arrived at 20% and only managed less than 100kw. I think that's what the OP may be alluding to about using chargers en route?
This is exactly what I was asking about. Thanks. I've got the general gist from some helpful replies. Real world experience of 50kw chargers in the UK.
to accept a decent rate of charge, the battery needs to be warm (> 30C or so) - so the charger and car will working to get the battery warmed up - that can take a fair bit of power, then the charge current is being limited in any event by the BMS. Charging lithium batteries can get complex. Some of the comments above that say that 50 KW in = 50 KW into the battery are slightly misleading. It can often be way less.
You'll get around 49kW right up to 85% assuming no load sharing etc. I regularly get this level from various 50kW units.
Watch Bjorne’s video that I posted above and you’ll see the same car, same 50 kW rapid returning two very different net charge efficiency results - from 82.5% into the car in the first attempt up (battery heater active and higher SoC) and later again with a warm battery (41C and lower 25% SoC) to 94.7% into the car, although he pulled it before the heater came back on after 15 mins. So huge difference based solely on SOC and heating up the battery or not.
Thanks mate. I'd searched for this topic before posting but this didn't come up! Got to get better as using the search function.
