Abstract

Efficient thermal management is critical for improving the safety, performance, and service life of lithium-ion batteries, especially in electric-vehicle applications. This study evaluates a mini-channel cold-plate system by examining the effects of coolant type, mass flow rate, and channel enhancement on heat dissipation using computational fluid dynamics (CFD) supported by experimental validation. Four fluids, namely water, acetone, ethanol, and methane, were examined at mass flow rates of 1×10-5, 1×10-4, and 1×10-3 kg/s. Among the tested fluids, acetone produced the lowest maximum battery temperature of 28.0 °C at 1×10-3 kg/s, while methane showed the weakest thermal performance. Increasing the mass flow rate consistently reduced battery temperature, but it also increased pressure drop and pumping-power demand. The results indicate that coolant selection should be based not only on thermal performance, but also on pumping-power penalty, safety, and environmental considerations. Although acetone delivered the best cooling performance in this study, its flammability limits its immediate practical adoption. The findings provide design guidance for the development of more effective mini-channel cooling systems for lithium-ion batteries.

Abstract

This paper presents the experimental development and evaluation of a PIC16F877A-based intelligent controller for voltage regulation and load prioritization in standalone photovoltaic (PV) home energy systems. The proposed system integrates a photovoltaic panel, battery storage, inverter, and embedded controller into a unified platform for efficient energy management. The controller continuously monitors battery voltage using an analog-to-digital converter and implements a threshold-based control strategy to disconnect non-critical loads when the voltage drops below 11.7 V. Experimental results show that the PV system maintains stable voltage characteristics within approximately ±3%, while the output current varies significantly with solar irradiance, exhibiting fluctuations of more than 60% under varying environmental conditions. The proposed controller effectively regulates system operation by dynamically managing load distribution, thereby preventing deep battery discharge and improving overall system reliability. In addition, the integration of auxiliary subsystems, such as automatic lighting and motion detection, enhances energy efficiency by reducing unnecessary power consumption. The findings demonstrate that the proposed low-cost PIC-based controller provides a practical and effective solution for intelligent energy management in standalone PV systems, particularly in off-grid residential applications.

Abstract

Mobile robot path tracking is a fundamental problem in control systems and robotics and has been widely utilized as a platform for integrating multidisciplinary concepts in mechatronics education. This study proposes an experiential learning framework for mobile robot control using a PID-based path tracking approach. The framework integrates theoretical control principles with hands-on implementation through the development of a differential-drive mobile robot equipped with reflective sensor arrays and a microcontroller-based control unit. The PID controller is applied to regulate robot motion based on real-time feedback, and its parameters (Kp, Ki, Kd) are tuned experimentally using a structured trial-and-error procedure. Experimental results indicate that the PID controller improves tracking stability and reduces oscillatory behavior compared to proportional-only control. The optimal parameter configuration (Kp=0.8, Kd=0.32, Ki=0.2) achieves stable tracking performance across different trajectory conditions, including curved paths. From an educational perspective, the proposed framework supports experiential and project-based learning by enabling systematic analysis of control system behavior through iterative experimentation. This work provides a practical and scalable approach for integrating control theory and robotic implementation in mechatronics education.
