Slow Charging Macan 4

[Billgoat]

Has anyone has a positive experience charging their Macan? My experience so far is less than stellar. While Porsche says their high speed charging can charge from 10-80% in 22 minutes, I haven't seen this, even while using the high speed charger at the dealership. I tried to use a level 2 charger at the dealership and sat for 20 minutes while my car added just 2 miles! We have level two chargers at work and my Tesla Model Y charged ~18 miles per hour. My Macan charges about 8-9 miles in a hour. I wonder if I'm doing something wrong? I don't see an option for preconditioning the battery but used navigation to the Porsche dealership to prime the battery but it was terribly slow. I was worried about charging this car since I'm used Tesla superchargers. Ugh.

A few things must be happening:

1. There are several variables that must be met in order to achieve maximum charge speeds assuming the charger is not broken and provides adequate charging power, and the variables are the following from the manual:

SoC: <10%
Charger Speed: >320kW
HV Battery Temp: 74F minimum and shown in the left tube with line bracket (on the right side) indicating optimal temp range to accept maximum charge. See graphic below that is from Taycan but it gives clear explanation of what you need to be looking for.

2. The Charger may not be providing adequate speed as it may be throttled or broken.

3. Your onboard charger is bad.

This is from the Taycan refresh launch that would be helpful to you. The only thing that Macan EV does not support is the predicted charge speed on the left of the battery graphic.

Also to confirm, high speed charging requires Level 3 charging.
The first post mentions Level 2 and that is nowhere near enough to hit 10-80% in 22 minutes - should still provide more than 2 miles per hour that said.

He said 2 miles in 20 minutes on a level 2 outside in winter. Indy is current below freezing. Normal.

Also need to use kWh if you want analysis.

First, I doubt you are doing anything "wrong". For folks here to help you unpack this, though, it would be helpful if you separated your Level 3 (DC) charging experiences from the AC charging experiences, and also if you would indicate KW charging rates rather than miles per hour, because the latter wraps in assumptions about efficiency which make it more difficult to interpret. (For example, most likely the Model Y is more efficient than the Macan, which is a separate issue from actual charging rate.)

That said, just as a starting point, suppose we assume that the Macan has an efficiency of 2.8 miles per kwh and the Model Y has an efficiency of 3.5 miles per kwh. The charging rates you indicate at work then imply something like 18/3.5 = 5 kw or 9/2.8 = 3.2 kw for the Tesla and Macan respectively. Are these rates on the same EVSE's? (I ask because the Tesla would be NACS while the Macan would be J1772 so if the same EVSE's then there is an adapter involved). Either way, the implied rate is well below what the Macan could accept on Level 2 (9.3 kw give or take), so I don't think the Level 2 experience is being limited by the Macan.

Similarly, we don't know the capacity of the Level 3 (I assume by "high speed charger") charger you tried at the Porsche dealer. From what I understand, with the right Level 3 (CCS) charger, the Macan should be able to charge from 10-80% quicker than the Model Y would be able to at a Tesla supercharger--but, are you comparing apples to apples? You would need to locate a properly-functioning 300+ kw CCS charger. (Note, this does not factor in that you may have a lot more success finding a fast Tesla supercharger than an appropriately fast CCS charger for the Macan, but that's not the Macan's fault.)

Also, different battery sizes, so 10-80% is a different amount of energy.

why aren't you using the free EA charging?
None near you?

and as noted L2 charging vs. FastDC charging are two wildly different things

also miles of range per hour of charge is ambiguous and based on optimistic consumption assumptions - the only way to compared two different EV's and their charging speed at different EVSE's is "kw" - kilowatts - how fast your EV charges at any given EV charger (called an EVSE) will depend on how much power the EVSE is providing

public commerical chargers from ChargePoint for example provide about 6 kW (208 volts @ 30 amps) - that is 6 kWh of power provided for each hour of charge - if your EV goes 2 miles/kwh that's 12 miles of range - if your EV goes 3 miles/kWh that's 18 miles of range, if you own a lucid it does about 4.5 miles/kWh so it will go 27 miles - but each EV got teh same amount of power from the EVSE…

if you want to compare you need to provide the kW's the EVSE is providing and we can then tell you want is expected.

I get 30mi an hour at home on both a 40A and a 48A EVSE so something is weird there. I'd suggest it's the charger, not the car.

At a fast charge I've definitely gotten 8%-80% in under 18 min. the first time I tried it.

L2 charging is AC based and therefore slow in charging and as a consequence there is no concept of or requirement to precondition the battery prior to charging. DC charging speed benefits from preconditioning only.

Check your L2 cable (EVSE to car) rating (amps) as it sounds like it is 50% below. what it should be e.g. 16A when it should be 32A (or US equivalent).

Also, the Macan EV has a 11kW AC onboard charger. What is the power output of the EVSE you are using? In contrast the Tesla you mention may have 19.6 / 22kW and so if the EVSE is rated at 22kW then it will charge twice as quick as your Macan EV.

You see lower charge per mile rates on AC as the Macan is not that efficient or you have driven it around not that efficient … They both have the same onboard AC charger specs … for Europe that is 11kw …
