1. A booster kit for reusing a battery, the booster kit comprising:
a battery connecting unit connected to a positive (+) electrode and a negative (−) electrode of a plurality of battery modules of the battery;
a plurality of converters, each converter being configured to convert a voltage of a respective battery module of the plurality of battery modules;
a current terminal configured to supply current of the plurality of battery modules to outside of the battery; and
a communication terminal configured to receive a control signal from a second control unit and transmit the control signal to a plurality of first control units,
wherein the plurality of first control units are configured to:
measure a voltage value of each battery module of the plurality of battery modules,
transmit the measured voltage value of each battery module of the plurality of battery modules to the second control unit separate from the booster kit,
receive the control signal generated in the second control unit, and
control an operation of the plurality of converters based on the control signal,
wherein the plurality of converters are configured to convert the voltage of the plurality of battery modules based on the control signal,
wherein the control signal generated by the second control unit includes a total voltage value for the plurality of battery modules, and
wherein each of the plurality of first control units is configured to control an operation of a respective converter, independently of the control signal, to convert a voltage of a respective battery module to output a voltage value so that the plurality of battery modules can output the total voltage value included in the control signal.
