Ummm. how one can un-plug if the owner with the key fob is not around (assume the car is locked). or do someone need to call the owner and owner unlock it from phone apps ?
The cable has two ends. One is usually locked into the car, the other end can sometimes be locked, sometimes not (depends on the charger installation). For those charging stations where you can unplug, it is sometimes possible for another EV to reach that cable, even when not in the charging spot, but one next to it. Personally, I have a thick 100+ foot extension cable (for 13A only), so I can be about 20 spots away from a charging spot and still use it.
If I can see my car will be done charging around 6 pm, I don't mind if someone arriving after that time unplugs the cable to charger their own car.
When someone arrives to find all charging spots in use (or ICEd), they can see on my sign when I plan to be back. Maybe I am coming any minute, and if in doubt, they can send me a message. Maybe I am early? Maybe I am nearby, and can go to the spot in a few minutes to move my car?
It's all about being considerate to other EV owners.
In 5 to 10 years when parking lots are crammed with chargers, we will look back and laugh at discussions like these.
"Remember back when we had so few charging stations that we had to make signs to show when we were back? And interrupt the middle of a movie or dinner, just to move the car to a non-charging spot? Can't imagine how we put up with it back then, now that chargers are everywhere"

I didn't use much time to cater for design details, just wanted something that worked here and now.

You can download the two pages above, including guidance how to use it:
Contact Sheet
Be aware that the MESSAGING FUNCTION will NOT work for cars that are NOT registered in Charged.hk!
If for some reason you choose not to be a charged.hk member, you can still use the document, just cut it off below the time-table.
You can sign up as free as well as paying member on charged.hk
It's highly recommended, you will help us support the EV charging infrastructure, and many more EV and clean air related aspects in Hong Kong. The more members we are, the more we are taken serious. Having said that, we are already being taken so serious that we recently attended a conference about EVs in HK at government level by special invitation. A briefing about it will be emailed to all members in a few days, so be sure to sign up NOW to hear more about it!
If you choose the free option ("Associate member"), then your
sent messages will be limited to emails, while you can receive both SMS and email notifications. Paying members are able to both send and receive SMS messages, and
it's all anonymous! That means that the two parties of an SMS exchange won't know each others SMS/email addresses, as it goes via the Charged.hk server. We (in Charged.hk) "do know who you are" so abuse will not be tolerated, obviously.
Please be polite and orderly, as markwj wrote, it's meant to communicate about the availability of EV charging spots.
Note that the linked PDF above is the generic QRCode, where you have to enter the registration of the car you are scanning.
Once a member of Charged.hk, you can download your personal QRcode which you can substitute into the document - that way, someone who wants to contact you don't even need to bother to enter your car plate registration.
(that is the reason I blackened the code out in the picture above!)
To make your own custom version (with your own QRcode or other changes), you can use these downloads instead:
OS X Pages version (original)
docx Word version (export from Pages, might need some reformatting to fit!)
