System and method for transmitting and receiving a data when charging an electric vehicle
First Claim
1. A system for transmitting and receiving data when charging a vehicle, the system comprising:
- a first module including an instantaneous state of charge (SOC) data storage unit and a processor configured to calculate an expected charging time based on the SOC value obtained through a controller area network (CAN) communication once charging the vehicle is started;
a second module including a second processor configured to determine a size of transmittable or receivable data considering a transmission speed, wherein the determination is based on information obtained through the first module;
communication equipment configured to transmit and receive data between the vehicle and a data center via a power line communication (PLC);
a first data storage unit provided within the vehicle and configured to store telematics related data;
a second data storage unit provided at the data center and configured to store the telematics related data; and
an output unit configured to output information related to data determined by the second module,wherein the second module identifies a service list transmitted from the data center considering the transmission speed and based on charging time information analyzed by the first module.

Abstract
A system and method for transmitting and receiving a data while charging a vehicle includes first module configured to calculate an expected charging time based on an instantaneous SOC value obtained through a CAN communication when charging the electrical vehicle is started and a second module that is configured to determine a size of transmittable or receivable data considering a transmission speed and based on information obtained through the expected charging time analysis module. Communication equipment enables data to be transmitted and received between the vehicle and a data center via power line communication. A first storage unit within the vehicle and a second data storage unit provided within the data center are configured to store telematics related data, and an output unit is configured to output information related to data determined by the second module.

6. A method of transmitting and receiving data when charging a vehicle, the method comprising:
-
receiving, by a first module including an instantaneous state of charge (SOC) data storage unit and a processor, an SOC value of a battery of the vehicle, the first module including the SOC data storage unit having memory that stores the SOC value received from the vehicle; calculating, by the processor of the first module, an expected charging time based on the SOC value obtained through a controller area network (CAN) communication when the vehicle is plugged in to be charged; recognizing, by the processor of the first module, a difference between a full charge amount and a current SOC amount and determining whether a high speed charging method or a low speed charging method is used by a charger to calculate the expected charging time; determining, by a second module, a size of data that is transmittable or receivable within the expected charging time; reading, by the second module including a second processor, corresponding data and data information among telematics related data of the vehicle in which the second module is stored to transmit the corresponding data and data information to a data center through communication equipment; outputting, by an output unit, telematics data to a driver prior to transmitting the telematics data to the data center to allow the driver to confirm a type of a data to be transmitted to the data center; and identifying, by the second module, a service list transmitted from the data center considering a transmission speed and based on charging time information analyzed by the first module. - View Dependent Claims (7, 8, 9)

10. A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:
-
program instructions that calculate an expected charging time based on an instantaneous state of charge (SOC) value obtained through a controller area network (CAN) communication when a vehicle is plugged in to be charged; program instructions that recognize a difference between a full charge amount and a current SOC amount and determining whether a high speed charging method or a low speed charging method is used by a charger to calculate the expected charging time; program instructions that determine a size of data that is transmittable or receivable within the expected charging time; program instructions that read corresponding data and data information among telematics related data of the vehicle to transmit the corresponding data and data information to a data center through communication equipment; program instructions that output telematics data to a driver prior to transmitting the telematics data to the data center to allow the driver to confirm a type of a data to be transmitted to the data center; and program instructions that identify a service list transmitted from the data center considering a transmission speed and based on charging time information analyzed by the expected charging time analysis module. - View Dependent Claims (11, 12)
