1. A battery diagnosis and data change device, comprising:
a communication unit connected to a connection unit and configured to transmit/receive data to/from a battery management system (BMS) configured to measure a temperature, a current, and a voltage of a battery module, and determine that the battery module is in a stable state in response to at least one of the measured temperature, current and voltage of the battery module satisfying a first preset control range for operation parameters of the battery module, wherein the data received from the BMS includes the first preset control range and battery operation data calculated by the BMS based on the measured temperature, current and voltage of the battery module, wherein the communication unit is configured to determine occurrence of overvoltage or overcurrent in response to at least one of the measured temperature, current and voltage of the battery module not satisfying the first preset control range;
a control unit configured to control data transmission/reception of the data to/from the BMS;
a diagnosis unit configured to determine a state of the battery module based on the battery operation data and the first preset control range received from the BMS;
a memory unit configured to store the determined state of the battery module; and
a change data input unit configured to transmit a preset data update containing a second preset control range to the BMS for changing the first preset control range in the BMS to the second preset control range.
