The Post-Pay transaction scenario for EV charging enables a customer to pay for the
electricity they use to charge their electric vehicle when the charging session ends.
The final transaction amount is calculated based on the amount of time or number of
kilowatts (kW) used during the EV charging session.

Post-Pay Transaction Workflow
The Post-Pay transaction workflow for EV charging typically consists of this sequence of
events:
The customer can choose a specific amount of time or the number of kilowatts
(kW) to charge their electric vehicle or can start a charging session for an
unspecified amount.
The customer presents a payment method to pay for the EV charging session.
The EV charging session starts.
The EV charging session ends when the customer's chosen amount of time or number
of kW is reached, the battery is fully charged, or the customer manually stops
the charging session.
The charging session transaction amount is calculated by the EV charging payment
system using the amount of time spent charging or the number of kW
consumed.
