Document Type and Number:
WIPO Patent Application WO/2019/078616
Kind Code:
A3
Abstract:
An electric vehicle charging apparatus according to an embodiment comprises: a first sensor for measuring a second voltage value between a first battery having a first voltage value and a relay in a high voltage line connected to electric vehicle charging equipment; a second sensor for measuring a third voltage value between the electric vehicle charging equipment and the relay in the high voltage line; and a control unit for controlling on/off of the relay, wherein if a difference between the second voltage value and the third voltage value is less than a preset fourth voltage value when the control unit applies a second battery voltage between the relay and the electric vehicle charging equipment in the high voltage line after controlling the relay to be turned off, the control unit determines that an operation of the relay is abnormal.
