Use a Ford Pro Charger 80 Amp on my Kia EV6

[Pioneer74]

The 19.2kW is peak output - 240V * 80A = 19,200W.

Your 17.9 is probably about where it should be after efficiency loss of about 5 ~ 7 % on the charge process under normal conditions. 17.9 / 19.2 = 0.93229 or 93.23%

I was just saying that absolute peak, possible output is 19.2kW, which is much lower than DCFC charge rates, so the charging rate doesn't need to be slowed until close to the end or target charge level.

I went back and edited my numbers. The biggest I've ever recorded is 17.7kW, and I'm measuring the wattage being delivered to the EVSE, not the truck. So I'm not even getting into the charging losses.

I measure 238V at the EVSE, so 17,700 ÷ 238 = approx 74 amps

@TaxmanHog - what are you seeing on your FCSP?

Interesting. You'd think the FCSP would do a bit better than that. But how can we know if it's the FCSP being not so great internally or if it's negotiating a lower rate than ideal with the truck? Or both? Perhaps Sandy Munro could tear apart a couple FCSP units and the charging system on the Lightning to get to the bottom of this... Heh.

All valid, and great, questions. Wish I had the answers.

Not a lightning, but my Volvo EV is set to pull 48amp, mm y evse supplies 30 and usually it charges at 28.5 to 29amp, never the full 30. If I remember correctly our bolt pulled the full 30. I have been charging the lightning weekly at a free location near work, so have not checked how much it pulls from the evse.

Not to go off topic, but had anybody ever seen anything close to that? I've never recorded anything over 17.5 to 17.6kW.

I‘m consistently seeing ~16.7-16.9 kW. I saw 17.6 kW ~5 min into last nights 76-91% FCSP charge session that lasted 2 hr 5 min (28.947 kWh delivered per FCSP Insights….with Preconditioning). Unfortunately, I didn’t CarScanner this session, but that 17.6 kW 5 min did catch my eye….

My truck charged at the full rate all the way up to 90% last night.

Good to know!
