[0001] Embodiments disclosed herein relate to a cassette for an electrical energy storage device, and more particularly to a cassette to accommodate at least one electrical energy storage device for use in electric vehicles.BACKGROUND

[0002] The adoption of electric vehicles (EVs) has been steadily increasing worldwide, primarily driven by environmental concerns and advancements in technology. However, conventional EVs face limitations such as lower range, higher charging times, and significant initial investment. To address these challenges, the industry is increasingly turning to electrical energy storage device interchange technology, particularly for heavy electric vehicles.

[0003] In heavy electric vehicles (HEVs), fixed electrical energy storage devices are commonly used, necessitating charging at dedicated charging stations. However, this approach presents limitations, including range anxiety, long charging times, and high initial costs. Electrical energy storage device interchange technology offers a promising solution by enabling quick electrical energy storage device replacement at the charging and interchange stations, eliminating the need for long charging sessions.

[0004] While the electrical energy storage device interchange system is straightforward for smaller vehicles, the heavy vehicle segment presents unique challenges. Designing a single high-capacity electrical energy storage device for heavy vehicles is impractical due to concerns such as potential electrical energy storage device damage, high replacement costs, and lack of scalability. Thus, there is a pressing need for a modular and scalable system capable of accommodating multiple electrical energy storage devices within a single device for electrical energy storage device interchange in heavy electric vehicles.
