Optimizing Energy Storage System for Electric Wheelchairs: A Comparative Analysis of Lithium Battery Technologies

Electric wheelchairs serve as indispensable aids for individuals with mobility impairments, offering them autonomy and freedom in their daily lives. However, the efficiency, lifespan, cost and range of the Energy Storage System (ESS) in electric wheelchairs pose significant challenges for users. To address these concerns, many wheelchair users resort to replacing the original ESS with car batteries, often perceived as offering superior performance. This paper aims to conduct a comparative analysis between three lithium battery technologies and the original ESS of a type B400 electric wheelchair, taking into account factors such as weight, volume, and cost. By evaluating these key parameters, the study seeks to identify the optimal alternative solution for enhancing the ESS of electric wheelchairs, thereby improving their overall performance and usability for individuals with mobility impairments.
