Abstract
The present invention discloses an auto re-closing device and method for an electric vehicle charging cable control device. The present invention is directed to an auto re-closing device and method for an electric vehicle charging cable control device, which are capable of stopping charging when a fault occurs and retrying to resume charging when charging is stopped.
Claims14
An auto re-closing device for an electric vehicle charging cable control device which is installed on a charging cable for supplying power to an electric vehicle from a power supply and controls charging of the electric vehicle, the auto re-closing device comprising:
- a fault sensor configured to sense a fault occurring during charging of the electric vehicle;
- a microcontroller unit (MCU) configured to control trying to charge the electric vehicle to be stopped when the fault occurs more than a predetermined number of times within a predetermined time, determine whether the fault is fixed after trying to charge the electric vehicle is stopped, and control charging of the electric vehicle to be retried when the fault is fixed;
- and
- a re-closing unit configured to disconnect or re-close connection between the power supply and the electric vehicle via the charging cable, under control of the MCU;
- wherein when a value of the fault sensed by the fault sensor is greater than a predeterminded threshold value, the MCU determines that the fault occurs and counts a number of times the fault occurs;
- and
- wherein when a value sensed by the fault sensor is less than a predetermined reference value which is less than the predetermined threshold value, the MCU determines that the fault is fixed.
A re-closing method for an electric vehicle charging cable control device which is installed on a cable for supplying power to an electric vehicle from a power supply and which performs an auto re-closing function of controlling charging of the electric vehicle, the auto re-closing method comprising:
- sensing a fault occurring during charging of the electric vehicle;
- a first control operation of controlling trying to charge the electric vehicle to be stopped when the fault occurs more than a predetermined number of times within a predetermined time;
- determining whether the fault is fixed after trying to charge the electric vehicle is stopped;
- and
- a second control operation of controlling the stopped charging of the electric vehicle to be retried when the fault is fixed,
- wherein the sensing the fault comprises determining that the fault occurs when a value of the fault sensed by a fault sensor is greater than a predetermined threshold value, and counting a number of times the fault occurs;
- and
- wherein the determining of whether the fault is fixed comprises determining that the fault is fixed when a value sensed by the fault sensor is less than a predetermined reference value which is less than the predetermined threshold value.
A computer program embodied in a computer readable medium causing a computer, which is installed on a cable for supplying power to an electric vehicle from a power supply and performing an auto re-closing function of controlling charging of the electric vehicle, to perform:
- sensing a fault occurring during charging of the electric vehicle;
- a first control operation of controlling trying to charge the electric vehicle to be stopped when the fault occurs more than a predetermined number of times within a predetermined time;
- determining whether the fault is fixed after trying to charge the electric vehicle is stopped;
- and
- a second control operation of controlling the stopped charging of the electric vehicle to be retried when the fault is fixed,
- wherein the sensing the fault comprises determining that the fault occurs when a value of the fault sensed by a fault sensor is greater than a predetermined threshold value, and counting a number of times the fault occurs, and
- wherein the determining of whether the fault is fixed comprises determining that the fault is fixed when a value sensed by the fault sensor is less than a predetermined reference value which is less than the predetermined threshold value.
