Newbie charging questions

Post by Crazymind » Mon Jun 29, 2020 11:56 am

Hi folks. Still quite confused about charging time and charge points on a long trip...
If I am correct our Ipace can take 22kwh on a DC charger. Meaning at home I can only get 7kwh on AC.
Are the charger points installed on public areas AC or DC?

No worries - let me try to explain it. Key to understand is that the speed you can charge is influenced by both the car and the charger.

Your question "Are the charger points installed on public areas AC or DC?"
Almost all home chargers are AC - the far majority of public chargers are AC - most fast chargers are DC and you tend to find them along the highway like Ionity, Fastned, etc.

Your question "If I am correct our Ipace can take 22kwh on a DC charger?"
You can charge faster on a DC charger - 22kW is an AC speed (3 phase 32 amps). DC speeds are 50kW or above.

Diving into more detail:
AC is called Type 2 and only uses the top part of the charging port plug.
DC is called CCS or Combo and uses both top & bottom part of charging port plug.

The MY2019-MY2020 I-pace has an 1 phase 32 amp onboards AC-DC converter which allows you to charge maximum gross 7.4kW per hour. If you connect to a 3 phase 16 amp charger (11kW charger) you will only charge with 3.7kW because the I-pace can't use the 2nd/3rd phase and the charge max aps is 16 so it is limited from both sides to 230 volt * 16 amps = 3.7kW. The new MY2021 I-pace can handle 3 phase 16 amps or 1 phase 32 amps NOT 3 phase 32 amps.

With DC charging there are more variables including outside temperature, SoC %, battery temperature, normal or liquid cooled cables and the DC charger max amps. So far the amps the I-pace DC charger can take is 250 and the voltage runs between 380-450 volt.
At a 50kW charger (125 amp * 400 volt) - the I-pace can maximum charge 50kW. Colder weather, multiple cars charging at that location, high SoC % will result in slow charge rates.
At HPC chargers the I-pace in theory could charge with 100kW but in real world it barely ever does and when it does usually only for short period (2-5 minutes). At some HPC chargers it is impossible - there are 100-160kW DC chargers with max 200 amps (200amps * 800 volt = 160kW) so on these the charger limited the amps to 200 and the I-pace limites the volts so max charge rate is 78-84kW if you SoC % is below 50%.

You’ll find both, but what you need for fast charging en route is a CCS DC charger. There are many of them giving 50kw or faster. A lot of chargers currently installed have three connections: 50kw DC (Chademo) which can’t be used with the I-Pace, 50 kw DC CCS which is the one you want, and an AC connection - can be anywhere for 11 to 43kw but 22kw is common on these chargers (with the MY19 & 20 you’ll get maximum 7kw from this and with MY21 you’ll get a maximum of 11kw from this). Chargers that are faster than 50kw are cropping up and becoming more common, but bear in mind your absolute Max charge rate will be 100 kw, so not worth choosing a 375kw Ionity over a 150kw BP charger as both will only give the I-Pace 100kw at best (it will actually more likely be around 80kw for most of the charge).

I know it’s all a bit confusing but you soon get used to it! A Better Route Planner will help if you download their app. You just put in your car and it will only show you chargers you can use and will stick to fast chargers.

Be aware that there are actually 2 main groups of 100kw-160kw DC chargers and sadly in most cases it is impossible to know in advance which one is which.
A) High voltage - lower amps (500-800 volt * 200 amps)
B) Lower voltage - higher amps (400 volt * 250-400 amps)

On type A - the I-pace is limited to 80kW-84kW as peak charging rates.
On type B - the I-pace in theory could charge 100kW at peak but in most cases is limited to 80kW.

From 175kW and up the amps of the charger will always be equal or higher than what the I-pace can handle so charging speed is not limited by the charger only by the I-pace.

Thanks. Answer Little bit more complex than expected... :) I will definitely need to learn something more about electricity. I am stack at switch on/off.
