What's about if the authentication works with a NFC chip which is in the membership card? authentication:nfc=yes or authentication:membership_card=yes? --Klumbumbus (talk) 18:54, 3 July 2014 (UTC)

RFID authentication

Is authentication:nfc=yes designed to include the traditional RFID chips present in many credit cards? I'm assuming that it is unless someone argues otherwise. T99 (talk) 23:03, 20 July 2014 (UTC)

Seems to be so. I thought at first this was for systems like ChargePoint, but those should use membership_card instead (even if they are using NFC.)

Power in kW

I propose a tag giving the maximal power in kW which a single charging point is able to give.


So a Schuko at 240 Volt can be used at 10 or 16 amp giving 2.4 or 3.7 kW

Voltage and amperage alone are not sufficient to calculate the maximal power a car can draw. With AC sockets it also depends on the number of phases. USA 1 phase, Europe and others 3 phases.

So a 240 Volt socket at 16 amp gives 3.7 amp with ONE phase (type 1 socket) but 11 kW with 3 phases (type 2 socket). At the moment this can only be calculated indirectly via voltage, amperage and socket type combined, but this is the most important information for a driver.

I agree with you, I also noticed that there is no way to map the max kw. In my understanding the amperage tag refers to the one connector with highest output. If there are multiple outputs this can be an issue, e.g.: One station with 2x Type 2 connector each with 32amp but the entire station is max powered with 22kw. This means if both connectors in use each can only be rated with ~27,5 A.

Type B sockets

The current documentation is somewhat Eurocentric and is not specifying the tags for some connectors used in the rest of the world. I will have to start using an undocumented tag socket=typeb to refer to receptacles which accept the grounded, polarized, 3-prong plug known as "Type B" plug and commonly used in households and offices in most of North America and parts of South America and Asia. I would also like to document the tag by adding the following to the table on the main page. -T99 (talk) 03:19, 21 July 2014 (UTC)

Tags Definition Photo Comments
socket:typeb=* the number of sockets for "Type B" plugs Domestic AC Type B USA.jpg Americas, Asia: NEMA 5-15 receptacle, also known as "Type B", maximum rating 125 V, 15 A (USA). The count should include any NEMA 5-20 (20 A) T-slot receptacles which accept NEMA 5-15 plugs. The nominal supply voltage varies by country between 110-127 V. The user must generally provide a portable "Level 1" trickle charger and connect it between the socket and the vehicle.

(Was not signed.)

Standard receptacles are a nightmare, so we should add them when they're in use. This one is.

Other Chargers


I'd suggest adding the following:

socket:type1_combo (J1772 "Frankenplug" w/ DC charging)

socket:tesla_roadster (Tesla Roadster plug. Not [as far as I know] available as a for-a-fee charging station, but since I have seen some at public places, I feel this should also be included)

socket:tesla_supercharger (Tesla supercharger. For use only on their supercharger stations.)

socket:tesla_standard (Standard plug, found on post-roadster cars.)

Supercharger and standard should be separate although the plug is the same since the supercharger connectors are DC-enabled and in all cases official (by Tesla themselves.)

socket:magne_charge (obsolete, but still installed in some places. For the sake of completeness)

Some places also offer high-amperage receptacles. Of these, the NEMA 14-50 is by far the most used to my knowledge. The TT-30 is also used (mostly at RV parks).

For these, you could use:

My problem is I cannot correctly assign the power of a socket. A CHAdeMO with an max ouput power of 50kW can have a different amperage related to the voltage of the battery. So Amperage is not a good choice for such sockets. Also a station can have more than one socket types which are limited to the max. of the station: A 50 kW triple charger can have a 50kW CHAdeMO, 50kW CSS and 2x 22kW Menekes Type2. But if more than one sockets are used, e.g. CHAdeMO and Menekes the CHAdeMO will be limited down to 20/25 kW. CHAdeMO + CSS usage is not allowed at the same time because both sockets use the same AC/DC charging unit.

How can we map it now? We use the old socket attribute but extend it with the power seperated by a colon. Here a view examples:

socket:schuko:2.3=2 means two Schuko plug with 2.3 kW output power (which is limited by a 10A circuit.) socket:schuko:3.6=2 means same but with 16A circuit.)

socket:cee_red_16a:11=1 means a cee red of type 16A with 11kW output power. socket:cee_red_32a:22=1 means a cee red of type 32A with full 22kW output power. socket:cee_red_32a:14=1 means a cee red of type 32A with limited output power by 20A circuit which is sometimes found.

socket:combo:43=1 means a combined socket type with a output power of max. 43kW. socket:chademo:50=1 means a combined socket type with a output power of max. 50kW.

To limit the whole charger a special attribute can be used like: socket:all:50=2 means on this combined charger max. 2 sockets can be used at the same time with a max. combined output power of 50kW on all sockets.

But to have better describtion I guess it's better to use a mechanism like the opening hours attribute which maybe can be declared as sockets (with s). The parsing is from left to right, where a new rule is beginnig with a socket name. The other in right of the last socket definition are the attributes of the sockets. the all socket type means a limit of all sockets to the right as long a new all socket has to been found. All keywords on left side up to the first socket are absolute declared limits. I use the following key words addionally as the attributes allready described:

power: power in watt phases: 0 for dc or dc, 1 for one phase, 3 for triple phase 120° phase movement plug: yes/no where yes means the chager has no socket, a cable + plug is availabe where then length: the cable length is known in m or feet ( e.g. 7m or 5ft) locking: yes/no which means, the socket locks the plug from foreign removement


A simple socket 2 charger with a limit of 11kW: sockets=type2:1 power:11000 voltage:400 phases:3 amperage:32

A simple chademo charger: sockets=power:50000 voltage:0-500 phases:dc chademo:1 plug:yes

A charging station which is used in my near by enercity with 1 Schuko 16A unlocked + type2 22kW which also can used by 7,6kW 1phase EVs: sockets=type2:1 power:22000 voltage:400 phases:3,1 amperage:32 schuko:1 voltage:230 phases=1 amperage=16 locking:yes

Another example with a limit declared by the special all key word of 35kW sockets=all:max power:35000 type2:1 power:22000 type2:1 power:11000 schuko:2 locking:yes power:3600

A double charger of 50kW with a chademo + css which is limited by a voltage range and only one of them can be used at the same time: sockets=all:1 power:50000 voltage:0-500 css:1 chademo:1

A tripple 100kW charger with one combined dc charger for css/chademo + two 22kW socket 2 cables sockets=power:100000 all:1 voltage:0-500 css:1 power:50000 chademo:1 power:50000 socket2:2 power:22000

Here a special private charger station I found: sockets=power:43000 cee_red_32a:2 cee_blue_32a:2 cee_red_16a:1 socket2:1 power:22000 schuko:2 cee_blue_16a:1

What do you think about?

A small change to my sugggestion is to use a keyword type: + amount: instead of use type:amount like type:socket2 amount:2 ... instead of using socket2:2. In this case a all:max will become type:all simply without the amount keyword. Another small difference is instaed of use type all use type limit to limit e.g. the power. Maybe better use all for declaring e.g. voltage aso.

Authentication via smartphone app

What's about authentication with a smartphone app, how do I tag this? I suggest: authentication:app=yes

In my case there is also a authentication possible via text so I only mapped this at the moment.

Parking situation

How do I map the parking situation? In Germany charging stations are often placed on regular parking areas.

  • The parking lots in front of the station can be reserved for electrical cars
  • The parking lots can be free only for electircal cars
  • The amount of reserved parking lots can be different to the amount of sockets at the station

So I think it would be helpful to map this informations as well.
