Design and Development of a 24 kWh Lithium Cobalt Oxide (LiCoO2) Battery Pack for Achieving a 300 km Vehicle Range

Abstract

This study presents the design and development of a 24 kWh lithium cobalt oxide (LiCoO₂) battery pack optimized for achieving a 300 km range in electric vehicles (EVs). LiCoO₂ was chosen for its high energy density of 266.5 Wh/m³, outperforming other lithium-based chemistries. The battery pack consists of 2,614 cells arranged in a 42S/64P configuration, providing a nominal voltage of 145.2 V and a capacity of 8 Ah. With a total weight of 198 kg, the design emphasizes energy density and structural efficiency, making it well-suited for high-voltage applications. The lightweight and compact structure of the LiCoO₂ battery pack enhances energy storage efficiency, making it ideal for hybrid electric vehicles (HEVs) and high-performance EVs. The design also highlights the need for robust thermal management systems to ensure safety and optimal performance during operation. This study confirms that LiCoO₂’s superior energy density and space efficiency provide significant advantages for long-range electric mobility, underscoring its potential in next-generation sustainable EV technologies.
