Abstract

A charging system includes a charging station. The charging station includes a charging unit, an input unit, a first communication interface, and a controlling unit. The input unit receives a model number message and a destination of an electric vehicle. The first communication interface receives a residual energy quantity message and an acceptable energy message of a chargeable battery of the electric vehicle. By comparing the model number message and the destination with a database, a type of the chargeable battery and a travelable path are realized. The chargeable battery is charged according to the type of the chargeable battery, the travelable path and the residual energy quantity message until a residual energy quantity of the chargeable battery is equal to an estimated energy quantity required to drive the electric vehicle to the destination along the travelable path.

Claims10

Dependent claims

A charging system for an electric vehicle, comprising:

a charging station configured for charging a chargeable battery of said electric vehicle and comprising:
a charging unit for providing a charging energy to said chargeable battery;
an input unit for selectively receiving a model number message of said electric vehicle and a destination of driving said electric vehicle;
a first communication interface in communication with said electric vehicle for receiving a residual energy quantity message and an acceptable energy message of said chargeable battery from said electric vehicle at any time;
and
a controlling unit electrically connected with said charging unit for controlling operations of said charging unit, and connected with said input unit and said first communication interface, wherein by comparing said model number message and said destination with a database, said controlling unit realizes a type of said chargeable battery and a travelable path of said electric vehicle from said charging station to said destination, wherein said controlling unit controls said charging unit to charge said chargeable battery according to said type of said chargeable battery, said travelable path and said residual energy quantity message until a residual energy quantity of said chargeable battery is equal to an estimated energy quantity required to drive said electric vehicle to said destination along said travelable path, wherein during said chargeable battery is charged by said charging unit, a magnitude of said charging energy is dynamically adjusted by said controlling unit according to said acceptable energy message.

3 more elements

A charging method for use in a charging system, said charging system comprising a charging station for charging a chargeable battery of an electric vehicle, said charging method comprising steps of:

(a) receiving a model number message and a destination of said electric vehicle, and receiving a residual energy quantity message and an acceptable energy message of said chargeable battery;
(b) comparing said model number message and said destination with a database, thereby realizing a type of said chargeable battery and a travelable path of said electric vehicle from said charging station to said destination;
(c) charging said chargeable battery by said charging station according to said type of said chargeable battery, said travelable path and said residual energy quantity message, wherein during said chargeable battery is charged by said charging station, a magnitude of a charging energy provided to said chargeable battery is dynamically adjusted according to said acceptable energy message;
and
(d) judging whether a residual energy quantity of said chargeable battery is equal to an estimated energy quantity required to drive said electric vehicle to said destination along said travelable path;
and
(e) if said residual energy quantity of said chargeable battery is equal to said estimated energy quantity required to drive said electric vehicle to said destination along said travelable path, said chargeable battery no longer being charged by said charging station, and if said residual energy quantity of said chargeable battery is lower than said estimated energy quantity required to drive said electric vehicle to said destination along said travelable path, said step (c) being performed again.
