In the rapidly evolving landscape of electric vehicles (EVs), particularly in the two-wheel segment, affordability and efficiency remain paramount. A recent study led by P. S. Praveena Krishna from the Department of Electrical and Electronics Engineering at the Manipal Institute of Technology has introduced a promising innovation that could reshape energy storage systems (ESS) for low-budget EV designs. The research, published in ‘Cogent Engineering’, presents a novel battery pack configuration tailored for low-power applications, boasting a capacity of 48 V and 3.84 kWh.
The challenge of balancing individual cell voltages and states of charge (SoC) within a battery pack is a significant hurdle in battery performance and longevity. Krishna’s team tackled this issue by implementing an active cell balancing method using a switched supercapacitor (SC) with a straightforward on-off hysteresis control logic. This approach not only enhances operational efficiency but also simplifies the circuit construction, making it a cost-effective solution for manufacturers.
“The differences in manufacturing processes and internal resistances among cells can lead to imbalances that degrade battery performance,” Krishna explained. “Our method allows for rapid balancing, which can significantly extend the life cycle of the battery pack.”
With the research validated through MATLAB/Simulink simulations, the findings suggest that this innovative balancing technique could dramatically improve the performance of lithium-ion battery packs. The implications for the construction sector are substantial. As the demand for affordable and efficient EVs grows, manufacturers can leverage this technology to produce more reliable and durable battery systems, ultimately leading to lower costs and better performance for consumers.
The integration of such advanced energy storage solutions is particularly relevant in the context of urban mobility, where two-wheelers are becoming an increasingly popular choice due to their convenience and reduced environmental impact. As cities strive to reduce congestion and emissions, the adoption of efficient EV technologies will be critical.
Krishna’s research not only addresses current challenges in battery technology but also sets the stage for future developments in the field. By focusing on simplicity and efficiency, this work could inspire further innovations that enhance the sustainability of electric mobility.
