Abstract
A system for diagnosing a battery cell using a substrate manufactured by an LDCMOS process, includes a master BMS and a plurality of direct BMSs, wherein a battery cell connection unit included in each direct BMS makes direct contact with a positive electrode terminal and a negative electrode terminal of each of a plurality of battery cells of a battery module to measure raw data of voltages of the plurality of battery cells and raw data of a current of the battery module, and in order to accurately process raw data of the voltages of the plurality of battery cells and raw data of the currents, a first substrate unit manufactured by the LDCMOS process and a second substrate unit including a configuration to wirelessly transmit and receive a signal generated and processed by the first substrate unit to and from the master BMS are provided.
