For charger manufacturers

Standard data access agreement

This is the agreement Joulo offers to every charger manufacturer or operator. One text, the same for everyone, with no price on access to the owner's data. You do not need to sign it to connect: the owner of the charger uses their own right for that. The text covers what is useful on top of that: access without passwords, fair use, support, and what happens when a route closes.

Why one text

The same terms with every brand

01

Equal for everyone

Every manufacturer gets the same text. The EU Data Act asks for that (Art. 8(3)), and it saves you and us a negotiation per brand.

02

Not needed to connect

The owner uses their own right to their data (Art. 4 and 5). This agreement covers what is useful on top of that: security, support and continuity.

03

Public

The text sits on this page, with a version and a date. Your customers can read what you and we agreed about their data.

What is not in it

We receive proposals from manufacturers too. These are the parts that appear in those proposals and are missing from our text, on purpose.

  • No price per charger, per session or per month.
  • No share of ERE revenue.
  • No reporting of our revenue or our payouts to the manufacturer.
  • No approval right over what we say in public.
  • No retroactive effect.
  • No cut-off of an owner without that owner's request.

The text

Standard data access agreement for chargers

Fifteen articles. References to Data Act articles are in brackets and refer to Regulation (EU) 2023/2854.

  1. Article 1

    Parties and purpose

    1. 1.1This agreement is between Joulo B.V. (Dutch Chamber of Commerce 42023359, Brummen) and the charger manufacturer or operator that signs it, hereafter the manufacturer.
    2. 1.2Joulo files charging sessions with the NEa, the Dutch emissions authority, on behalf of the charger owner and pays the proceeds to that owner. To do so, Joulo reads the charging session data of the charger.
    3. 1.3Within the meaning of the Data Act, the manufacturer is the data holder, the owner is the user, and Joulo is the third party that receives data at the user's request (Art. 2 and 5).
  2. Article 2

    Access at the owner's request

    1. 2.1The owner authorises Joulo through an affirmative action in their own account. Joulo records the date, time and wording of that authorisation and shows them to the manufacturer on request.
    2. 2.2After that authorisation, the manufacturer makes the charging session data of that charger available to Joulo: without undue delay, of the same quality as is available to the manufacturer, and free of charge to the owner (Art. 5(1)).
    3. 2.3If the owner withdraws the authorisation, Joulo stops fetching new sessions within 72 hours. Sessions already filed are settled as the Dutch energy-for-transport rules require.
    4. 2.4The manufacturer states per charger whether it has a MID-certified meter inside the housing, and provides the evidence on request: type approval and meter serial number. Only kWh from that meter count with the NEa (Regeling energie vervoer, Art. 9).
    5. 2.5Per charging session the manufacturer provides the start and end time and the readings of that meter at the start and at the end. The NEa files only what the meter of the charge point delivered to the vehicle.
    6. 2.6At the request of Joulo's independent verifier, the manufacturer confirms the data delivered for a charger, up to five years after the calendar year it relates to.
  3. Article 3

    No price for access

    1. 3.1The manufacturer charges no fee per charger, per session, per month or as a share of ERE revenue. Such a fee comes out of the payout to the owner and also counts for chargers that earn nothing.
    2. 3.2Joulo is an SME within the meaning of the Data Act. Any compensation to Joulo is therefore limited to the costs directly related to making the data available (Art. 9(4)).
    3. 3.3If the manufacturer asks for such a cost-based compensation, it provides the calculation (Art. 9(7)). Joulo pays after agreeing to that calculation, per calendar year in advance, and never retroactively.
  4. Article 4

    Access without passwords

    1. 4.1The manufacturer offers a route by which the owner grants Joulo access without sharing their password: OAuth 2.0 with refresh tokens, or an API key the owner creates themselves.
    2. 4.2A token stays valid until the owner revokes it. A security measure on the owner's account, such as two-factor authentication, does not affect the delegated access.
    3. 4.3As long as that route does not exist yet, the manufacturer does not block access the owner has authorised themselves. The new route comes first, then the old one closes.
  5. Article 5

    What Joulo does with the data

    1. 5.1Joulo uses the data for the ERE filing, the owner's dashboard and the checks the NEa and the independent verifier require. For nothing else.
    2. 5.2Joulo does not resell the data and shares it only with the NEa, the verifier and the parties the owner designates.
    3. 5.3Joulo does not use the data to build charger management software that competes with the manufacturer's (Art. 6(2)).
    4. 5.4Joulo keeps the data for five years after the end of the calendar year it relates to, the retention period of the Dutch energy-for-transport rules, and deletes it afterwards.
  6. Article 6

    Fair use

    1. 6.1Joulo polls the API at most once every 15 minutes per owner, or listens to webhooks if the manufacturer offers them.
    2. 6.2Joulo fetches the history from 1 January 2026 once, at the first connection.
    3. 6.3The manufacturer publishes its limits. Joulo respects them and reports when a limit breaks the integration.
  7. Article 7

    Security

    1. 7.1Joulo runs an information security management system in line with ISO 27001:2022. Credentials are stored encrypted in a vault, traffic runs over TLS, and staff see only what their task requires.
    2. 7.2Each party reports a security incident that affects the other within 72 hours of discovery.
    3. 7.3Joulo never shares credentials with a third party.
  8. Article 8

    Support and continuity

    1. 8.1Each party names a technical contact and answers a question about the integration within five business days.
    2. 8.2The manufacturer announces an API change that breaks the integration 90 days in advance, with documentation.
    3. 8.3If the manufacturer wants to close a route, it gives twelve months' notice, effective at the end of a calendar year, and offers a working replacement: another API, OCPP 1.6J, or an export the owner can start themselves. The old route closes only once the replacement works.
    4. 8.4The manufacturer does not cut off an individual owner from Joulo, except at that owner's request.
    5. 8.5After a route closes, the data for the last calendar year stays available until 1 March of the following year, the day the NEa closes filing for that year. After that it stays available on request for a correction or a verification.
  9. Article 9

    The owner chooses

    1. 9.1Neither party restricts the owner's choice. No exclusivity (Art. 8(4)) and no choices offered in a non-neutral manner (Art. 4(4)).
    2. 9.2The manufacturer does not describe a connection the owner has authorised as unsafe or unauthorised in messages to that owner.
    3. 9.3Both parties leave the owner free to choose their charger and their ERE service provider.
  10. Article 10

    Equal terms

    1. 10.1Joulo offers this text to every manufacturer, in the same version, and publishes it on joulo.nl. Joulo signs no arrangement with one manufacturer that puts another manufacturer at a disadvantage (Art. 8(3)).
    2. 10.2An addition for one manufacturer goes into an annex to this text. That annex puts no price on access and does not change Articles 2 to 4.
  11. Article 11

    Openness

    1. 11.1Both parties may say in public that the integration exists and how it works. A factual statement needs no prior approval.
    2. 11.2A party uses the other's logo only with permission. Naming the brand in a list of connected brands is always allowed.
  12. Article 12

    Personal data

    1. 12.1Each party is an independent controller for its own processing. If a data processing agreement is needed, the parties conclude it before the processing starts.
    2. 12.2The parties exchange no more personal data than the integration requires.
  13. Article 13

    Liability

    1. 13.1A party is liable only for direct damage caused by an attributable failure. No limit applies in case of intent or gross negligence.
    2. 13.2If the manufacturer closes a route in breach of Article 8, or blocks authorised access in breach of Article 4, it compensates the payout the owners miss as a result. Joulo calculates that per owner from the charging sessions of the preceding twelve months and the latest sale price in its sales log, and passes the amount on to the owners.
    3. 13.3For other damage, each party's liability is limited to the payout the owners concerned received from Joulo over the preceding twelve months.
  14. Article 14

    Term and termination

    1. 14.1The agreement runs for an indefinite period. Either party may terminate with twelve months' notice, effective at the end of a calendar year. Filing runs per calendar year, so a route never stops halfway through a year. Article 8 applies during that notice period too.
    2. 14.2Termination of this agreement does not end the owner's right under the Data Act. An authorised connection continues for as long as the owner wants.
  15. Article 15

    Law and disputes

    1. 15.1Dutch law applies to this agreement. The parties first try to resolve a dispute by consultation within 30 days. If that fails, the court of Gelderland has jurisdiction.
    2. 15.2For a dispute about the owner's access to their data, the ACM, the Dutch supervisor for the Data Act, is open as well.
