Your charging data
What does your brand do with your charging data?
Every kWh you charge at home is worth money. So whoever holds your charging data holds your money. This score tells you per brand how free you are: can you have your sessions fetched by the ERE service provider you choose, without a password, without a fee and with your history? High is open. Low is not.
Last checked 2026-09-25. Every row rests on our own integration, not on what a brand promises.
How we score
Five questions, ten points. A brand that signs the standard agreement gets one point extra.
Works today
You can have your sessions fetched right now by a party you choose, without conditions.
No price on your data
The brand charges your ERE service provider no fee for access. That fee would otherwise land on your statement.
Without a password
You grant access with your own key or by consenting at the brand, not by sharing your password.
History from 1 January
Your sessions since 1 January 2026 come along, including what you charged before you connected.
Standard signed
The brand signed the standard data access agreement and put this in writing.

| 5/10Restricted | Vattenfall InChargePlatform |
| Since 25 June 2026 Vattenfall refuses the sign-in route through which owners authorised a new connection. Existing connections continue; there is no official route for third parties. |
| 3/10Restricted | 50fivePlatform |
| A forced password reset on 28 May 2026 broke connections customers had authorised themselves. There is no route without sharing credentials. |
| 3/10Restricted | E-Flux by RoadPlatform |
| On 9 August 2026, customer-authorised connections became invalid, only on Road's own-brand environments. Road itself writes that you can connect to the ERE service provider of your choice. Source |
| 3/10Restricted | ZaptecCharger brand |
| Zaptec's API policy (updated 21 September 2026) forbids third parties to use the owner's password. Today that is the only route that works for owners. The password-free route in Zaptec's own documentation opens only after an arrangement with Zaptec. Directly over OCPP 1.6J the route stays open. Source |
