KONA IONITY POST BMS UPDATE - SPEED TEST

I started a new thread as the DC - DC Curve thread is all over the place, so as this is just about the Ionity speeds though it better new.

After our Slow Rapid Charger Charging issues and BMS update failure,

I thought I would try and post something positive about it all.

So I wanted to do a Low to 80% Charge on an Ionity HPC to see if the time it takes to charge had changed post update.

I was planning to arrive with less than 10% but the car is just so efficient I didn't manage it and arrived with 12% left.

OUTSIDE AIR TEMP AT START 28c
BATTERY TEMP AT START 34c
BATTERY TEMP AT END 46c

Plugged in and off it went, started at 73kw not as high as the 77kw I see when its colder but with high outside temps and very warm battery still very acceptable

CHARGING CURVE AS FOLLOWS

12% to 60% Above 71Kw (Very surprised with this as it always used to throttle from the 70s at about 51%) So thats a good gain

60% to 76% At 56Kw

76% to 80% At 36Kw

TOTAL TIME TO GET FROM 12% to 80% : 45MINS

ENERGY ADDED IN 45 MINS : 47Kw


CHARGING SPEED Assuming 4.2Miles/Kwh = 47 / 3 * 4 = 62.66 Kw per hour

4.2 Miles per Kwh (About average for motorway driving) 4.2 x62.66 = Charging Speed of 263 Miles Of Range Per Hour

Very Happy with that anything over 250 miles of range added per hour is a great result.

Only downside was that battery was so hot when we unplugged at 80% it was using 1Kw an hour to cool the battery all the way home (Over and Hour)

So from the looks of these speeds it looks like the new BMS update has shaved 8 to 10 mins off a 10% to 80% Charge

I had to read that line twice ...
