Charging Speed - Mustang Mach E Premium - Only 80KWS Max

[dolvio]

To be clear, the preconditioning starts at 30km (18.6 miles) from the charger. 8 minutes isn't going to do anything. Couple that with arriving at 58%. And the battery wasn't 6C, it was likely colder.

I can understand that completely. I can’t imagine anyone using the chargers around here are driving from at least 30km’s away. The battery was probably warmer than 6C as it was in my garage before my short trip. This is a hyper charger (380kwh) and getting 55kwh is a joke. I’ve been able to get 60kwh at a 180kwh shared power charger.

Nobody charging around me is likely ever under optimal charging conditions. It’s all short trips, no pre conditioning, cooler weather right now yet my car is charging at half the speed as everyone else. I just don’t get it.

It sounds like you're describing optimal conditions for a L2 EVSE in your garage.

Not sure what that really means.

Err..... hyper charger (380kwh) and getting 55kwh is a joke. I’ve been able to get 60kwh at a 180kwh shared power charger. -----could you tell us what a charging curve is?

Not sure I understand what your message is about.

There’s a lot of irrelevant and irreverent advice in this thread!

Another thing you can do is find a nice hotel with an L2 charger and a good honeymoon suite and take your spouse (or lover, or random hookup) there and charge overnight while you enjoy each other’s “company”. Free charging!!!! The slower the better in that situation.

haha where do you find the spouse, love, or random hookup to test this method?

Not sure what that really means.

It means they should install an L2 EVSE at home and avoid having to go to DC fast chargers.

We go once a month for the sake of it.

The chargers are rated in kW, not kWh. kWh is what makes it into your battery and what it can hold.

A charging curve means that it starts out at 150 kW at low SOC, and as the battery "fills up", the kW tapers over time. So while you are getting a high rate at 50% to 70% SOC, it gradually tapers to less than 60 kW when you get to 80% SOC, and then further drops to less than 30 kW as you pass 90% SOC.

Why pay higher prices if you don't have to? There's DC fast chargers just down the street from work, but I use the work-provided ones because they are only 20 cents a kWh instead of the 50+ cents that EA charges.

Yep, I know. Thanks.

SaintKevin is the author of kWh statement. I'm not sure he understand this DCFC business.

I quoted your specific post which used kWh. Apparently both of you used kWh when you should've used kW.

Yes, that was new EV driver misspeak. Being a month in I'm more tuned to the frequencies and terminology now, but still a lot to learn.
