Monitoring charging power consumption

[Dave T]

Does either the standard "Porsche Mobile Charger Connect" (or the associated app) allow you to monitor how much power you use when doing your nightly charging? I'd be interested in seeing the draw at the current moment, as well as daily/weekly/etc totals for how much power I used to charge the car, as well as what it cost me.

If it doesn't give you that info, I guess I'd look into setting up a monitorable current clamp on my charging line.

I use the Curb system. It works very well.

Thanks. A link would have helped, but I found it:

This appears to be similar to the system I use:

https://sense.com/

But I don’t think sense will be able to separate out the power consumed just by the car charger. Can Curb do that? How?

Sorry.

Yes. Unlike the Sense system, Curb has multiple clamps which you put on the circuits you want to monitor. Here's what my home is doing right now.

When I'm charging the "EV Charger" spikes up to 9-10kW.

Isn't the Sense supposed to differentiate the appliances using power? It might be able to isolate the car charger. I dunno.

Ah, ok. Sense tries to be “smart” by using signal processing algorithms to detect individual device types by their “signature” when they turn on and off. It’s cool when it works, but it often doesn’t and just groups all unknown devices together. They have to write code for every device type and I’m not holding my breath for them to add recognition of the Taycan charger. So maybe I’ll get Curb. But in theory, Sense would be better for me. I have 8 electrical panels in my house, so it isn’t practical to put a current clamp on every breaker.

So the Porsche charger can’t tell you your power usage?
