1. An electric vehicle charging system, comprising:
- a charging station which comprises;
a power delivery system;
a power transfer measurement unit; and
a communication system configured to communicate with an electric vehicle; and
a charging monitor mounted in the electric vehicle which comprises;
a power transfer measurement unit; and
a communication system configured to communicate with the charging station;
a controller, which is configured to control the power delivery from the charging station to the electric vehicle based on a comparison of a first power transfer measurement made by the charging station and a second power transfer measurement made by the charging monitor mounted in the electric vehicle;
a vehicle payment module; and
a station payment module, wherein the vehicle payment module is configured to transfer funds to the station payment module, and the controller is configured to implement the power delivery in increments, and to implement the funds transfer in corresponding increments.
