1. A system for controlling charge and discharge using paddle braking, the system comprising:
an input unit inputting a braking command to a vehicle;
a regenerative braking unit performing driving and regenerative braking of the vehicle;
a load unit including a plurality of auxiliary loads using electrical energy charged in a battery; and
a control unit receiving the braking command and controlling the driving and the regenerative braking, wherein the control unit performs:
dividing a time section into a plurality of sections including a discharge section and a regenerative braking section;
in response to receiving the braking command input, changing an operation time of at least one of the plurality of auxiliary loads, which operates during the discharge section among the plurality of sections, to the regenerative braking section among the plurality of sections, so that the electrical energy generated by the regenerative braking is directly used by an operation of at least one of the plurality of auxiliary loads without being stored in a battery; and
wherein the plurality of sections comprises:
a braking intention prediction section which is a section between a braking starting time and a first time when actual regenerative braking starts;
a regenerative braking charge section which is a section between the first time and a second time when a driver releases a paddle braking command;
a paddle braking release section which is a section between the second time and a third time when an actual paddle braking release command is confirmed; and
a driving motor discharge transition section which is a section between the third time and a braking ending time, and
wherein the regenerative braking charge section and the paddle braking release section are sections that the regenerative braking is performed.
