Module Identifier: chargingprofiles
Type: Functional Module
With the ChargingProfiles module, parties (SCSP but also MSPs) can send (Smart) Charging Profiles to a Location/EVSE. It is also possible to request the 'ActiveChargingProfile' from a Location/EVSE.
The ActiveChargingProfile is the charging profile as calculated by the EVSE. It is the result of the calculation of all smart charging inputs present in the EVSE, also Local Limits might be taken into account.
The ChargingProfile is similar to the concept of Charging Profiles in OCPP, but exposes this functionality to third parties. These objects and the accompanying interfaces make certain abstractions that make them more suitable for energy parties to signal their intent. The data structures are base on OCPP 1.6 and 2.0 to make conversion of messages between OCPI and OCPP easy.
Note
|
Charging Profiles set via this module are no guarantee that the EV will charge with the exact given limit, it is a maximum limit, not a target. A lot of factors influence the charging speed. The EV might not take the amount of energy that the EVSE is willing to provide to it, the battery might be too warm or almost full. A single phase cable might be used on a three phase Charge Point. There can be local energy limits (load balancing between EVSEs on a relative small energy connection to a group of EVSEs) that might limit the energy offered by the EVSE to the EV even further. |
ChargingProfile can be created by the owner of a Token on Sessions that belong to that token. If another party sends a ChargingProfile and the CPO has no contract that allows that party to set profiles on sessions, the CPO is allowed to reject such profiles.
This module can be used by the eMSP, but can also be used by another party that provide "Smart Charging Services" (Smart Charging Service Provider (SCSP) / Aggregator / Energy Service Broker etc.) These SCSPs then depend on the CPO sending session information to them. They need to know which session is ongoing to be able to influence it. If a SCSP uses this module, read eMSP as SCSP.
Note
|
OCPI provides the means for SCSPs to do this. Parties doing this have to adhere to local privacy laws, have to have setup contracts etc. Local laws might oblige explicit consent from the driver etc. |
Module dependency: Sessions module
There are different Smart Charging Topologies possible. Which topology can be used depends on the contracts between different parties.
Note
|
Care has to be taken to prevent mixing the different topologies. When multiple parties start sending Charging Profiles, the resulting charging speed might be unpredictable. In case of OCPP Charge Points, the result will be the minimum of all the Charging Profiles, resulting in a slower than needed charging speed. |
The most straight forward topology, the eMSP generates ChargingProfiles for its own customers, no SCSP is involved. The eMSP 'owns' the customer, so if the eMSP knows that its customer agrees with the eMSP manipulating the charging speed, the eMSP is free to do this.
Interface | Role |
---|---|
Sender |
eMSP |
Receiver |
CPO |
In the topology, the eMSP has delegated the generation of ChargingProfiles to a SCSP. For this, the eMSP and SCSP have agreed to use OCPI as the interface.
The eMSP 'owns' the customer, so if the eMSP knows that its customer agrees with the eMSP manipulating the charging speed, the eMSP is free to do this. The eMSP can forward OCPI Session Objects to the SCSP. the SCSP can act on the received/updated Session Objects, by sending Charging Profile commands via the eMSP to the CPO.
The eMSP and SCSP have to take into account that they have to oblige to local privacy laws when exchanging information about eMSPs customers.
From the CPO point of view, this topology is similar to the one above, the CPO will not know the difference.
Connection | Interface | Role |

In this topology, the CPO has delegated the generation of ChargingProfiles to a SCSP. For this, the CPO and SCSP have agreed to use OCPI as the interface.
The CPO 'owns' the EVSE on which charging happens. As the CPO does not 'own' the customers, the CPO needs to make sure the EV driver knows that the charging speed might not be the maximum the driver has expected, this could be something as simple as a sticker on the Charge Point, or might even be part of the tariff text.
The CPO might generate ChargingProfiles themselves, but as OCPI is then not used this is not part of this document.
The CPO can forward OCPI Session Objects to the SCSP. the SCSP can act on the received/updated Session Objects, by sending Charging Profile commands to the CPO.
The CPO and SCSP have to take into account that they have to oblige to local privacy laws when exchanging information about eMSPs customers.
In this topology, the eMSP is not aware that the CPO is using OCPI to receive Charging Profiles from the SCSP.

This module is designed to support the following use cases, for all the above mentioned topologies.
-
The eMSP/SCSP sends/updates a ChargingProfile to manipulate an ongoing charging session.
-
The eMSP/SCSP request to remove the set ChargingProfile from an ongoing charging session.
-
The eMSP/SCSP request the ActiveChargingProfile for an ongoing charging session.
-
The CPO updates the eMSP/SCSP of changes to an ActiveChargingProfile.
The ChargingProfile creation is a request to activate a charging profile on a running charging session.
Most Charge Points are hooked up to the internet via a relative slow wireless connection. To prevent long blocking calls,
the ChargingProfile module is designed to work asynchronously. (similar to the Commands
module.
The Sender (Typically SCSP) sends a request to a Receiver (Typically CPO), via the Receiver interface. The Receiver checks if it can send the request to a Charge Point and will respond to the request with a status, indicating if the request can be sent to a Charge Point.
The Receiver sends the requested command (via another protocol, for example: OCPP) to a Charge Point. The Charge Point will respond if it understands the command and will try to execute the command. This response doesn’t always mean that the ChargingProfile will be executed. The CPO will forward the result in a new POST request to the Sender (Typically SCSP) ChargingProfile interface.
The Sender (Typically SCSP) can send the Charging Profile to the EVSE via the CPO by using the CPO PUT method for an ongoing session. The Sender can request the current profile the EVSE has calculated, based on different inputs, and is planned to be used for the ongoing session by calling the CPO GET method. The Sender has the ability to remove the Charging Profile for the session by calling the CPO DELETE method
When the Sender has (at least once) successfully sent a Charging Profile for an ongoing charging session, the Receiver (Typically CPO) SHALL keep the Sender updated with changes to the ActiveChargingProfile of that Session. If the Receiver is aware of any changes, he notifies the Sender by calling the MSP PUT method. The changes might be triggered by the CPO sending additional Charging Profiles, or the some local limit being applied to the Charge Point, and the Charge Point notifies the CPO of the Changes.
The Receiver can cancel/remove an existing ChargingProfile, it can let the eMSP know by calling the MSP PUT method
For calculating optimum ChargingProfiles it might be useful for the eMSP or SCSP to know the ChargingProfile that the Charge Point has planned for the Session: ActiveChargingProfile. The ActiveChargingProfile might differ from ChargingProfile requested via OCPI. There might be other limiting factors being taken into account by the CPO and or Charge Point, that limit the ChargingProfile. The ActiveChargingProfile profile can be requested by the Sender by calling the CPO GET method on the Charging Profile Receiver interface. The CPO will then ask the Charge Point for the planned ActiveChargingProfile. When that is received it is forwarded to the URL given by the eMSP or SCSP.
The CPO can limit the amount of request that can be done on the Charging Profiles interface, this too prevent creating a too high load or data usages. To do this the CPO can reject a request on the Charging Profile Receiver interface be responding with: TOO_OFTEN.
If the Sender (typically eMSP or SCSP) wants to have a reference between the calls sent to the Receivers interface and the asynchronous result received from the Charge Point via the CPO, the Sender can make some unique identifier part of the`response_url` that is part of every method in the Receiver interface. The Receiver will call this URL when the result is received from the Charge Point. The Sender can then match the unique identifier from the URL called with the request.
When a new Session is started, or when an update to an existing Session is available, the CPO sends the Session object to the eMSP or SCSP. The eMSP or SCSP calculates a Charging Profile and sends it to the CPO by calling the Charging Profiles PUT method on the Receiver interface.
The CPO responds to the eMSP or SCSP, the response body will contain the response to the request, acknowledging the request was understood and can be forwarded to the Charge Point.
The CPO sends the requests to the Charge Point. When the CPO receives a response from the Charge Point, that result is sent to the eMSP or SCSP by call the POST method, on the URL provided by the eMSP of SCSP in the PUT request, this call will contain a ChargingProfileResult Object.
When a new Session is started, the CPO sends the Session object to the eMSP, the eMSP forwards the Session object to the SCSP.
When a new Session is started, or when an update to an existing Session is available, the CPO sends the Session object to the eMSP. The eMSP forwards the Session Object to the SCSP. The SCSP calculates a Charging Profile and sends it to the eMSP by calling the Charging Profiles PUT method on the Sender interface implemented by the eMSP. The eMSP forwards it to the CPO by calling the Charging Profiles PUT method on the Receiver interface.
The CPO responds to the eMSP, the response body will contain the response to the request, acknowledging the request was understood and can be forwarded to the Charge Point. The eMSP forwards this response to the SCSP.
The CPO sends the requests to the Charge Point. When the CPO receives a response from the Charge Point, that result is sent to the eMSP by the POST method, on the URL provided by the eMSP in the PUT request from the eMSP. The eMSP forwards this result to the the URL provided by the SCSP in the PUT request of the SCSP, this call will contain a ChargingProfileResult Object.
1.3.3. Example of a removing/clearing ChargingProfile sent by the Sender (typically the eMSP or SCSP)
The Sender might want to remove the charging profile, for example the EV driver has selected to switch to charging with the highest speed possible. The Sender can ask the CPO to remove the set charging profile. This can be done by calling the DELETE method on the Receiver interface.
The CPO responds to the eMSP or SCSP, the response body will contain the response to the request, acknowledging the request was understood and can be forwarded to the Charge Point.
The CPO sends the clear requests to the Charge Point. When the CPO receives a response from the Charge Point, that result is sent to the eMSP by call the POST method, on the URL provided by the eMSP in the DELETE request of the eMSP, this call will contain a ClearProfileResult Object.
The SCSP might want to remove the charging profile, for example the EV driver has selected to switch to charging with the highest speed possible. The SCSP can ask the eMSP to ask the CPO to remove the set charging profile. This can be done by calling the DELETE method on the eMSPs Charging Profile Receiver interface. The eMSP forwards this to the CPO by calling the DELETE method on the CPOs Charging Profile Receiver interface.
The CPO responds to the eMSP, the response body will contain the response to the request, acknowledging the request was understood and can be forwarded to the Charge Point. The eMSP forwards this response to the SCSP.
The CPO send the clear requests to the Charge Point. When the CPO receives a response from the Charge Point, that result is sent to the eMSP by call the POST method, on the URL provided by the eMSP in the DELETE request of the eMSP. The eMSP forwards this result to the the URL provided by the SCSP in the DELETE request of the SCSP, this call will contain a ClearProfileResult Object.
When the Sender wants to know the current planned charging profile for a session, the Sender can ask the CPO for the ActiveChargingProfile by calling the GET method on the Receiver interface.
The CPO responds to the eMSP or SCSP, the response body will contain the response to the request, acknowledging the request was accepted and can be forwarded to the Charge Point.
The CPO sends a message to the Charge Point to retrieve the current active charging profile. When the CPO receives a response from the Charge Point, that ActiveChargingProfile is sent to the eMSP by call the POST method, on the URL provided by the eMSP in the GET request of the eMSP, this call will contain a ActiveChargingProfileResult Object.
When the SCSP wants to known the current planned charging profile for a session, the SCSP can ask the the eMSP to ask the CPO for the ActiveChargingProfile by calling the GET method on the eMSPs Charging Profile Receiver interface. The eMSP forwards this to the CPO by calling the GET method on the CPOs Charging Profile Receiver interface.
The CPO responds to the eMSP, the response body will contain the response to the request, acknowledging the request was accepted and can be forwarded to the Charge Point. The eMSP forwards this response to the SCSP.
The CPO sends a message to the Charge Point to retrieve the current active charging profile. When the CPO receives a response from the Charge Point, that ActiveChargingProfile is sent to the eMSP by call the POST method, on the URL provided by the eMSP in the GET request of the eMSP, this call will contain a ActiveChargingProfileResult Object. The eMSP forwards this result to the the URL provided by the SCSP in the GET request of the SCSP, this call will contain the same ActiveChargingProfileResult Object.
When the CPO knows the ActiveChargingProfile of a Charge Point has changed, the Receiver (typically the CPO) sends this update ActiveChargingProfile to the Sender (typically the eMSP or SCSP), by calling the PUT method on the Sender interface.
1.3.8. Example of the Receiver (typically the CPO) sending an updated ActiveChargingProfile to the SCSP via the eMSP
When the CPO knows the ActiveChargingProfile of a Charge Point has changed, the Receiver (typically the CPO) sends this update ActiveChargingProfile to the Sender (SCSP), by calling the PUT method on the eMSPs Sender interface.
The eMSP forwards this ActiveChargingProfile to the SCSP, by calling the PUT method on the SCSPs Sender interface.
The ChargingProfiles module consists of two interfaces: a Receiver interface that enables a Sender (and its clients) to send ChargingProfiles to a Location/EVSE, and an Sender interface to receive the response from the Location/EVSE asynchronously.
Typically implemented by market roles like: CPO.

There are no URL segment parameters required by OCPI.
As the Sender interface is called by the Receiver (typically CPO) on the URL given response_url
in the Sender request to the Receiver interface.
It is up to the implementation of the Sender (typically SCSP) to determine what parameters are put in the URL.
The Sender sends a URL in the POST method body to the Receiver.
The Receiver is required to use this URL for the asynchronous response by the Charge Point.
It is advised to make this URL unique for every request to differentiate simultaneous commands,
for example by adding a unique id as a URL segment.
Endpoint structure definition:
No structure defined. This is open to the eMSP to define, the URL is provided to the Receiver by the Sender. Therefor OCPI does not define variables.
Examples:
https://www.server.com/ocpi/2.2.1/chargingprofiles/chargingprofile/12345678
https://www.server.com/activechargingprofile/12345678
https://www.server.com/clearprofile?request_id=12345678
https://www.server.com/ocpi/2.2.1/12345678
The content of the request body depends on the original request by the eMSP to which this POST is send as a result.

Result of the DELETE ChargingProfile request, from the Charge Point. |
The response to the POST on the Sender interface SHALL contain the Response Format with the data field omitted.
Updates the Sender (typically SCSP) when the Receiver (typically CPO) knows the ActiveChargingProfile has changed.
The Receiver SHALL call this interface every time it knows changes have been made that influence the ActiveChargingProfile for an ongoing session AND the Sender has at least once successfully called the charging profile Receiver PUT interface for this session (SetChargingProfile). If the Receiver doesn’t know the ActiveChargingProfile has changed (EVSE does not notify the Receiver (typically CPO) of the change) it is not required to call this interface.
The Receiver SHALL NOT call this interface for any session where the Sender has never, successfully called the charging profile Receiver PUT interface for this session (SetChargingProfile).
The Receiver SHALL send a useful relevant duration of ActiveChargingProfile to send to the Sender. As a guide: between 5 and 60 minutes. If the Sender wants a longer ActiveChargingProfile the Sender can always do a GET with a longer duration.
Endpoint structure definition:
{chargingprofiles_endpoint_url}{session_id}
