What is a CDR?
The charge detail record: the digital receipt of a session with energy, duration and tariff. It travels from the operator to the eMSP and becomes a line on the invoice.
Explained in
Why 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.Much of what the operator receives is spent again quickly. Energy purchase is the largest variable cost, followed by the site host's rent or revenue share, hardware depreciation and service. How many sessions a site sells therefore decides its result, as stop 7 shows.

Related questions
- Why do drivers pay different prices at the same charger?Each commercial route prices the session differently: a contract with an eMSP, a subscription with a monthly fee, or ad hoc payment at the operator's own price.
- Can I charge without a contract?Yes. Since April 2024, every new public charger in the EU must allow ad hoc payment, by card at 50 kW and more. The price is shown before the session starts.
- Why does public charging cost more than charging at home?The prices cover different things. A public charger's price includes hardware, grid connection, site, service, payment and a margin; a household tariff pays for energy on an existing connection.
- Why does charging involve so many companies?Three things spread the work: the grid connection, the location where people park, and contracts that work across many networks. One company can hold several roles, but the roles stay separate.
