I understand standard on-board charger is 7.2 kW, but in term of electrical outlet which I will have electrician to set up this week should it be 220V 16A? or 220V 30A ? to optimize the 7.2 kW charger

Please advise

 

The standard is not 7.2kw, it is 3.6kw (at least here in the US). The 7.2kw is an option at around $800. Double check to see which one you have. But here are the specs.

For the 3.6kw you only need a 220v 20amp (the charger is rated at 16 amp, but you need the breaker to be 20 amp)

For the 7.2kw (if you got that option) it is 220v 40 amp. As with the above it needs be higher then the rated 30amp of the charger. That rule applies to all EV charger wiring.

I have the 7.2kw option and it charges to full in about 75 minutes or so.

 

Thank you so mine is 3.6kw given it is standard one , I ordered mine from UK if I set my breaker to be 30-32 amp would it makes charges faster?

 

You can't charge faster then your charger's capacity (3.6kwh). So anything over a 20 amp dual pole breaker is a waste of $. Unless you plan to add another higher charge rate EV in the future that may utilize it.

 

I installed my charger with on a 220/240 30 amp. I used 25' 10/3 wire and a two pole 30 amp breaker and 6' of conduit and a NEMA 6-50 outlet. Total cost at Home Depot was $83, and I did the install.

3.6kWh Porsche 2015 S E-Hybrid charges completely in 2:25 min versus the old 11 hours at 120v

 

How about your E-power range? my Porsche 2015 S E-Hybrid charges completely in ca 4:30 min but only give range of 16 KM , I thought the range suppose to be 35 KM?

I am getting 16 miles consistently (26km).

The only exception is if I use battery mode up a very steep grade. Hills seem to suck the life out of the battery. Beyond that, I am happy with my range.

The 35km range is overstated, like all EV cars that state a high end range that is not really achievable.

What does the first part of your commute look like? Hills, high speed, bumper to bumper traffic, etc?

 

bumper traffic like LA

 

That may be the problem. Especially if you have the AC cranked and seat ventilation or other accessories.

I would drive it on a normal highway speed drive once to see how it does for range as a comparison.

 

How about the acceleration when the battery is empty? Specs say 5.9 seconds for the 0-100 sprint but I'm guessing that's with a fully loaded battery

 

The system keeps 20% of the battery in reserve for stop/go driving and additional power needs like acceleration.

 

Interesting, so what happens when you're at 20% reserve and you accelerate? It's going to deplete eventually right?

 

Yes, if you are under the 20% it deactivates ePower mode (battery only) and switches to hybrid mode. In that mode, it will use that 20% for hard acceleration or for stop and go (creeping in very slow traffic). Once it gets down to near zero it will start to run the engine a little higher (like in eCharge) to get back to 20% automatically.

 

Thanks for the info.
