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 2026-11-06. Every row rests on our own integration, not on what a brand promises.
How we score
Five questions, ten points. Every score matches the ticks: no rounding, no bonus.
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 us no fee for access. That fee would otherwise land on your statement. What the brand charges others, we do not know.
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 in writing
Access is set down in writing: in the standard data access agreement, in a standard integration agreement the brand signed with us, or in an open protocol such as OCPP.

With some brands the brand's app then stops working, unless your ERE service provider forwards the traffic to your brand's platform. We do that on request. |
