Electric vehicles (EVs) have developed rapidly and are popular due to their zero
emissions and efficiency. However, several factors limit electric car
development, including battery performance, cost, lifetime, and safety. Battery
management is crucial for achieving maximum performance under various
conditions. The battery thermal management system (BTMS) plays an important role
in controlling the battery’s thermal behavior. A BTMS manages the battery’s
operating temperature by either dissipating heat when it is too hot or providing
heat when it is too cold. Various methods of cooling batteries include air
cooling systems, liquid cooling systems, refrigerant cooling systems, and phase
change material cooling systems. This study focuses on an innovative BTMS
utilizing a Peltier module, regulated via the Internet of Things (IoT) platform
for real-time temperature monitoring and control. The objective of this research
is to design and develop a temperature-controlled cooling system for EV
batteries, with the ability to dynamically adjust cooling intensity and send
alerts for anomalies. The system comprises temperature sensors, a (NodeMCU)
microcontroller, and the Peltier module, all interconnected wirelessly to the
IoT platform, enabling remote management through a mobile application. The
experimental setup successfully maintains the battery temperature within a range
of 35°C–45°C, optimizing performance and preventing overheating. Real-time data
monitoring and cooling adjustments, based on temperature readings, led to a
significant improvement in thermal management, enhancing the battery’s
efficiency and longevity.
