Design of Battery Monitoring System for Electric Vehicle

Abstract: Lithium-ion batteries are expected to be the primary source of energy for the future generation of transportation systems. Following the standard industrial communication protocol, this study describes a methodical approach to designing an effective hardware test bed for Battery Monitoring System (BMS) applications in the Electric Vehicle (EV) industry. The hardware test bed collects both battery voltage and current data acquisition.The architecture of a battery hardware test bed is then described, as well as the reasoning for picking key components such as the microcontroller and voltage/current sensors. The batteries are initially charged to their maximum capacity. The initial battery powers the vehicle. The source is switched to the second battery when the first battery goes below a particular level (low battery).
