Public charging routine in a nutshell

[Weeble]

OK, to some of you wise old owls this post may appear as a little 'basic', and bits and pieces have been discussed recently elsewhere so I may be in threat of duplication, but can we please develop some sort some sort of a Public Charging Routine for newbies specific to the S5 and pin it somewhere -- the handbook is next to useless.

I've had my S5 for almost 6 months now and have never needed to use public charging. However, over the coming days I'll be going farther afield and will need to use a public charger for the first time, so I thought I'd have a 'play around' tonight to see what does what.

I have no problem with how to use the public charger itself so I put my home charger in 'Boost' mode to manually turn it on, as a substitute for the public supply.

TEST 1
=====
1. Plugged in
2. Locked car
Nothing happened

TEST 2
====
1. Turned off scheduled charging in car and App
2. Plugged in
3. Locked car
Charge started

TEST 3
====
1. With car charging
2. Unlocked car to sit inside
3. Charging stopped
4. Sit in car (don't press brake)
5. Turn car OFF from pull-down menu
Charging resumes

TEST 4
====
1. Press the Stop Charging button on the App
Charging stops.

Questions:
Is this a recommended 'standard' procedure to follow or have I missed something (i.e. are there any other setting that need to be checked)?

There appears to be alternative ways of turning off the charge, so which one is recommended?

The help info on the car charging screen says that the purpose of the charge % setting allows the charger to keep going after a scheduled charge session ends, until the battery reaches the set %. In practice I've always found that the charger reaches the set % before the schedule ends and stops at that point.
The Set % field disappears when the scheduled charge is turned off on the car screen, but stays visible on the App screen. So does the % limit still take effect in a non scheduled charge session or does the car keep charging to 100% unless interrupted?

Hopefully not too daft a question.

Merry Christmas to all......

Not that I use it, but my charger also has a timer on it, so, I guess, if you want a totally foolproof checklist, you need to check that the charger is going to be willing to pump out the electrons throughout your charging period.

But, as I say, mine is set to 24/7; I rely on the car to suck when required, not on the charger to blow.

No need to turn car off.

Assuming a CCS rapid - remove rubber port cover, plug in charger, pay for it, wait for it to handshake with the car and start charging (around 30 seconds). Either get back into car, or lock car and go do something else.

Whether the car is powered on or off shouldn’t make a difference.

Yes, it will stop charging if it reaches the limit set in the app.

Some chargers will have a stop button which you can simply press, others require you to swipe your card again to bring up the stop screen.

You can simply unplug the car to stop the session without manually stopping.

Are you sure? It seems to me that it won't (AC) charge unless locked. Have I misinterpreted?

Interesting reply. I'm sure in my test the charge didn't start until I locked the door. I wonder if CCS and type 2 systems gave different requirements.
There are both types of charger at the local pub so I might have to venture out for a quick christmas eve half tomorrow.

On my MG4, unlocking the car pauses AC charging for about 30 seconds, then resumes. It's not obvious that the charge is paused from the car display. During the pause, the cable is unlocked, abd relocks when charging resumes. I assume that this behaviour would be similar on other MG EV models.

I don't recall what happens with rapid DC charging.

If you are charging at home (AC) the car has to be locked before it will start charging. If you unlock it the car will pause charging before restarting.

Fast charging (DC) it doesn't matter if the car is locked or not.

For using a fast DC charger:
1. Plug car into charger
2. Swipe payment card or if using an app select charger and press charge or whatever is required for that app.
3. You might have to take the weight off the plug so the top two terminals make proper contact for the electronic handshake. You can let go after that's done.
4. When finished swipe card again/stop the charge in the app.

What @Ian Key said!

They do, as Ian points out.

That's a very useful tip. I haven't seen that mentioned before, so thanks.

I'm in slight conflict over the 'car must be locked' issue with home charging.....
At home, I'm using an Ohme charger with Octopus Intelligent Go and the Ohme App.
If I programme the required home charge amount on the Ohme app, and then approve the charge request on the app, the car will start charging if the Smart Meter bizz deems it worthwhile to start charging whether the car is locked or not. I've seen it start charging whilst the car is unlocked with the home charger.
With the public rapid chargers, I'm in agreement - the car doesn't have to be locked for the charge to start.

In my experience it is the act of locking the car that causes the charging cable to become locked in at both the car and the charger.

I totally agree that locking the car locks and secures the charging cable.
I don't agree that home charging requires the car to be locked before charging begins. I've seen several charging sessions where I see my charging indicators turn green before I lock the car, indicating that charging has started.

Just my experience.....

I should have added: charging doesn't seem to start until the cable becomes locked in (in my experience).
