IoT Based Heat Management System for Electric Vehicle

Abstract

Growing electrification of road transport has made battery pack reliability a central concern for engineers and manufacturers alike. Heat accumulation within battery cells is among the foremost contributors to accelerated wear and unexpected failure. This article presents a networked, sensor-driven solution that autonomously oversees and adjusts the thermal state of EV battery assemblies. Multiple measurement nodes relay live temperature and electrical readings to a central embedded processor, which evaluates prevailing conditions and energizes cooling or warming devices as dictated by programmed safety logic. Acquired data travels over wireless links to hosted cloud services, affording engineers and operators unimpeded remote visibility. The outcome is a self-correcting system that maintains cell temperatures within tolerable bands, curbs stress-induced wear, and accumulates historical records useful for forecasting future maintenance needs. Bench-level trials confirmed reliable temperature stabilization and a meaningful improvement in operational robustness. The modular construction of the design permits straightforward adaptation to battery packs of varying sizes and chemistries.
