The present invention relates to a parallel charging device for electric vehicles and a control method therefor. The device according to the present invention includes a driving motor which receives DC charging power from a rapid charger, a motor-driving inverter which boosts the DC charging power supplied from the rapid charger through the driving motor and transmits it to a high-voltage battery, an on board charger (OBC) which boosts the DC charging power supplied from the rapid charger and transmits it to the high-voltage battery, and a power distribution unit which distributes the DC charging power supplied from the rapid charger and supplies it to the motor-driving inverter and the OBC, wherein the motor-driving inverter and the OBC are connected in parallel to the high-voltage battery.
