บทคัดย่อ
—Public Electric vehicles have been used in many cities around the world. Lithium batteries are mostly used as an energy source for those electric vehicles due to their efficiency and versatility. For safety reason, Battery Management System (BMS) is required for comprehensive monitoring and fault diagnosis of a lithium battery pack. To monitor the BMS operation, a remote BMS monitoring system is a solution. Low-power long-Range Wide Area Network (LoRaWAN) has been deployed in many applications that require low-power, long-range communication due to its unique transmission modulation. Applying a LoRaWAN technology to fleet of electric buses can be cost-effective solution for many large cities around the world. Moreover, there is no additional cost for utilizing the LoRaWAN frequency spectrum in many countries around the world since LoRaWAN usually operated on unlicensed spectrum. In this work, a BMS monitoring system based on (LoRaWAN) protocol is developed. Electrical parameters from a BMS including individual cell voltage, current, temperatures, State of Charge (SoC) and state of Health (SoH) are transmitted over the LoRaWAN at AS923-925 frequency plan (923-925 MHz). The communication range analysis was performed based on Received Signal Strength Indicator (RSSI) and a monitoring system dashboard. ©2024 IEEE.
