DATA TRANSMISSION DEVICE AND METHOD BETWEEN CHARGER AND ELECTRIC VEHICLE
First Claim
1. A data transmission device used between a charger and an electric vehicle, comprising:
- an internal interface compatible with messages or commands of a first protocol;
an external interface compatible with messages or commands of a second protocol;
an outside-to-inside transformation module, being adapted to receive messages or commands of the second protocol from the electric vehicle, to transform the messages or commands of the second protocol into messages or commands of the first protocol according to functions of data carried by the messages or commands, and to send the messages or commands of the first protocol to the charger; and
an inside-to-outside transformation module, being adapted to receive messages or commands of the first protocol from the charger, to transform the messages or commands of the first protocol into messages or commands of the second protocol according to functions of data carried by the messages or commands, and to send the messages or commands of the second protocol to the electric vehicle;
wherein the messages or commands sent from the outside-to-inside transformation module to the charger include;
a CER message for carrying an end-of-charge request of the electric vehicle;
a CSR message for carrying a start-of-communication request, a start-of-charge request and a battery type identifier of the electric vehicle;
a CCS message for carrying charging status of the electric vehicle; and
a CCR message for carrying a charging level request of the battery of the electric vehicle; and
wherein the messages or commands sent from the charger to the inside-to-outside transformation module include;
a POC message for carrying configuration parameters related to an output capacity of the charger; and
a POS message for carrying real-time status of the charger.
