VEHICLE CHARGING SYSTEM WITH CHARGING EFFICIENCY CONTROL AND PROVIDING ADAPTIVE CHARGING SERVICE
First Claim
1. A vehicle charging system, comprising:
- a power grid; and
at least one charging station connected to and communicated with the power grid through a power transmission interface, and communicated with an electric vehicle through an electric vehicle communication interface for charging the electric vehicle;
wherein the at least one charging station comprises;
a power module for receiving a first electric power from the power grid and converting the first electric power into a second electric power;
an adaptive charging control circuit for issuing a charging command for controlling the charging operation of the electric vehicle according to commands indicative of demands for electric energy of the electric vehicle; and
a power manager for managing the power module according to the charging command issued by the adaptive charging control circuit and a loading of the power grid, thereby regulating and limiting a charging current provided for the electric vehicle.

Abstract
The invention discloses a charging system for electric vehicle which includes at least one charging station. The charging station includes a socket breaker. When the connection between the charging pump of the charging station and the socket lock on the charging stand of the vehicle is not secure or the charging current for charging the vehicle is too large, the socket breaker will open to shut down the power supply for the socket lock of the vehicle, thereby terminating the charging operation for the vehicle. Also, the charging station includes an adaptive charging control circuit and a power manager for regulating the charging current for the vehicle according to the charging demands of the electric vehicle and the loading of a smart grid/utility grid, thereby providing flexible and adaptive charging service for the vehicle.

10. A vehicle charging system, comprising:
-
a power grid; and at least one charging station connected to the power grid through a power transmission interface for receiving a first electric power and converting the first electric power into a second electric power for charging an electric vehicle; wherein the at least one charging station includes a socket breaker for controlling whether the at least one charging station is allowed to charge the electric vehicle, and wherein when the at least one charging station is determined to be disallowed to charge the electric vehicle, the socket breaker is open to shut down power supply for a socket lock mounted on a charging stand of the electric vehicle, thereby terminating the charging operation for the electric vehicle. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
