1st Gen Superchagers Materially Slower Than Newer SC's?

[houstonian]

SCing now on the "classic" SCs with 60kw being the peak. Arrived here (Waco) with 6% left, weather conditions are moderate (73), and the car is a software limited S60.

Yesterday the charge topped out around 96kw at the brand new Flatonia SC and the conditions were similar.

Do others find the "classic" SCs to be slower than the new ones or is it just me?

The original superchargers were 90 kW, then 120 kW, then 135 kW. But I thought all the 90's had been upgraded.

I've never in my four years of ownership encountered a 60 kW Supercharger. Even the first ones put in can now go to 120 kW.

Actually my experience is the opposite. The older ones were putting out more power than the new ones. But that was about 6-9 months ago. I think the new chargers issues are mostly solved.

Don't forget that the S60 has lower voltage than the 85/90/100. The older superchargers (square-ish metal pedestal instead of the nice, lighted plastic and metal ones) were limited to 90kW but It could be possible that this was because of current limits (amps). With lower voltage (because of the 75 kWh pack) and lower current (old supercharger) you'll end up with a bigger penalty.

Does it explain the difference, maybe not but I think that would be a good avenue for further investigation. Too bad that the car doesn't show Volts and Amps now when supercharging....

Greetings all - three more SCs today confirm my observations. Still on the road but should be able to post the TeslaFi SC logs.

Data from a recent road trip per TeslaFi logs:


Waco SC - Older Design
~5m SuperCharging at 92-97kw; 7:53am - 7:58am; the GREEN bar on the graph tracks this.

Huntsville SC - Older Design
~10m SuperCharging at 92-97kw; 10:35pm - 10:45pm; the GREEN bar on the graph tracks this.

Denton / Razor Ranch SC - Newer Design
~9m SuperCharging at 92-97kw; 10:29am - 10:38am; the GREEN bar on the graph tracks this.

Arlington SC - Newer Design (brand new - just opened the week prior!)
~7m SuperCharging at 92-97kw; 6:34pm - and 6:41pm; the GREEN bar on the graph tracks this.

Amarillo SC - Newer Design
~8m SuperCharging at 92-97kw; 10:36am - and 10:44am; the GREEN bar on the graph tracks this.

So after looking at my data the weak link appears to be the Waco SC (?)

All other SCs, both the new type and old, were able to deliver longer periods of max charging. In my case this equated to 7-10m of charging at 92-97kw and then tapering off as expected.
