CDR

Charge detail record: the digital receipt of a session, with energy, duration and tariff.

Explained in

EV charging fundamentals · Stop 05Why do different drivers pay different prices?Same charger, same hour, three prices. How contracts, subscriptions and ad hoc card payment price one session differently, and where the money goes.

After every session, a CDR (charge detail record) travels from the operator to the eMSP: the digital receipt with energy, duration and tariff. It becomes a line on the driver's invoice, so its accuracy matters to everyone in the chain.
