Battery-pack diagnostic system for vehicles

A vehicle battery pack diagnostic system, comprising:

• a battery module installed inside an electric vehicle and including at least one battery therein;
• a housing that accommodates the battery module and includes a switch and a display on an upper outer surface thereof;
• at least one sensing module installed inside the housing and configured to detect a status of the battery module;
• a battery management system (BMS) module installed inside the housing and configured to:
• output first warning message data related to charging of the battery module when temperature data of the battery module detected by the at least one sensing module exceeds a preset first temperature threshold, and
• output second warning message data related to charging of the battery module when voltage data of the battery module detected by the at least one sensing module exceeds a preset first voltage threshold;
• a wireless communication module movably coupled to one end of the upper portion of the housing, configured to receive an external control signal for the battery management system module, transmit management data of the battery management system module to an external device, and communicate through a Bluetooth Low Energy (BLE) short-range wireless communication method;
• and
• a communication connector module connected to the other end of the upper portion of the housing and configured to enable Controller Area Network (CAN) communication between the battery management system module and a vehicle electronic control unit (ECU).
