Charging time on a 50kw charger

[RobboWWFC]

Being as most public chargers here in the UK are 50kw. How long would it take to get 100 miles of range from one of these?

Just less than about an hour I’d recon. 50 minutes maybe?

At 350wH/m it'd be 42 minutes. (I just picked 250mi range and 88 kwH battery to come up with that)

At the twenty 50kW stations I used on my trip, I saw charge rates from 28 to 47kW, averaging at 43-44kW.

So you can get 100 miles of range in approximately an hour. (YMMV)

On average it's 21-25 kwh / 100km. So to charge 50 kw for one hour you will get 50kwh which will give 200km. (@ 25kwh/100km)

To get to 100 miles or 161 km, that will be 161/200*60 = 48 minutes.

I agree with Louv’s findings, the U.K. 50kw chargers I have used usually only give around 43kw ( I have not seen more than that yet ( on about 10 different chargers). Most of the time I have used them I have still been over 50% charge remaining though. So about an 1hr for 100 miles is roughly right

Since the Taycan's charge rate taper is sooooo good - math on how many kWh you will get for 1 hour of charging is pretty simple for chargers of a 120 kW or less...

the Taycan really never gets below 50 kW of charge rate due to taper until very very close to the end

so any charger 50, 100 or even 120 kW = 1 hour of charge = the charge rate of the charger in kWh.

since there is no taper - the kW rating is essentially the kWh rating for 1 hour of charging

50 kW = 50 kWh of charge for 1 hour of charging

Maybe in a theoretical world but in reality the chargers do not deliver the 50 kW power. I have charged at several with my cars and agree with @louv . The car might not taper off but something does

my apologies for being unclear - yes 50 kW chargers only deliver something like 90% of their rated charge to the car, but as far as kWh are concerned the Taycan has such a good taper at lower kW ratings that what ever charge rate you are seeing - will pretty closely translate to kWh for 1 hour of charge…that was my main point - since there is no taper - kw = kWh for one hour of charge

so if you're getting 43 kW at a 50 kW charger, your rate for 1 hour of charging will be 43 kWh - so you can pretty easily "know" how much you'll get for 1 hour of charging - if there is taper involved the math becomes slightly more complex, but can be approximated for 1 hour by taking 1/2 or 2/3 of the charge rate for estimate kWh for 1 hour of charge

I agree with you there. But I have still seen a small difference of maybe 5% or so between what the charger is saying and what I will pay for, compared to what the car is showing,. Nothing to really worry about, but the chargers seldom deliver the full power they advertise in my experience.
